CCDS Exam — Questions and Answers

Question 1: Under the Cooperating Parties coding guidelines, which organization provides the official publication for ICD-10-CM/PCS coding advice?

ACDIS (Association of Clinical Documentation Integrity Specialists)
AHA Coding Clinic for ICD-10-CM/PCS (Correct answer)
AHIMA Standards of Ethical Coding
CMS Medicare Claims Processing Manual

Correct answer: AHA Coding Clinic for ICD-10-CM/PCS

AHA Coding Clinic for ICD-10-CM/PCS is the official publication for coding guidance, published by the American Hospital Association under the authority of the Cooperating Parties (CMS, NCHS, AHA, AHIMA).

Question 2: A CDI specialist documents in the query that clarifying a diagnosis to 'acute kidney injury' will increase reimbursement by $4,000. This practice is:

Compliant because transparency about reimbursement supports accurate coding
Non-compliant only if the amount exceeds $1,000 under OIG guidelines
Non-compliant because queries must not reference financial impact or DRG changes (Correct answer)
Compliant if the physician is also informed of the clinical rationale

Correct answer: Non-compliant because queries must not reference financial impact or DRG changes

Including financial impact or DRG information in a query is non-compliant and can constitute improper influence on physician documentation.

Question 3: A patient is admitted with a heel wound that has been present for two months. The physician documents 'heel ulcer, etiology unclear.' What should the CDI specialist do?

Code it as a pressure ulcer based on the wound's location
Default to diabetic foot ulcer if the patient has diabetes
Leave the code unspecified as the physician's documentation is sufficient
Query the physician to clarify whether it is a pressure ulcer, arterial ulcer, diabetic ulcer, or other type (Correct answer)

Correct answer: Query the physician to clarify whether it is a pressure ulcer, arterial ulcer, diabetic ulcer, or other type

Etiology drives ICD-10-CM code selection for heel wounds, so the CDI specialist must query for clarification to ensure accurate coding and appropriate DRG assignment.

Question 4: When a patient is admitted for chemotherapy and also has the malignancy being treated, which condition should be sequenced as the principal diagnosis?

The chemotherapy encounter (Z51.11) (Correct answer)
The malignancy
The complication with the highest CC/MCC weight
The most resource-intensive condition

Correct answer: The chemotherapy encounter (Z51.11)

Per ICD-10-CM guidelines, when admission is for chemotherapy, Z51.11 (encounter for antineoplastic chemotherapy) is sequenced as the principal diagnosis.

Question 5: A patient with CKD Stage 3 (baseline creatinine 1.8 mg/dL) presents with creatinine of 3.2 mg/dL. The physician documents 'CKD Stage 3 with acute exacerbation.' What is the best CDS action?

Downgrade to CKD Stage 4 based on current creatinine
Query whether AKI on CKD should be documented, as the creatinine rise exceeds 1.5x baseline (Correct answer)
Code only CKD Stage 3 as documented
Code acute renal failure and CKD Stage 3

Correct answer: Query whether AKI on CKD should be documented, as the creatinine rise exceeds 1.5x baseline

The creatinine rise from 1.8 to 3.2 mg/dL represents a >1.5x increase meeting AKI criteria; querying for AKI on CKD ensures accurate coding and higher DRG specificity.

Question 6: Which of the following best describes the 'POA exempt' status of a HAC on the CMS HAC list?

The condition cannot be coded as a secondary diagnosis
The MS-DRG payment is not adjusted even if the condition is not POA (Correct answer)
CMS exempts the hospital from reporting the HAC to the state
The HAC is excluded from all quality reporting programs

Correct answer: The MS-DRG payment is not adjusted even if the condition is not POA

When a HAC is designated as POA exempt, CMS will not adjust the MS-DRG payment even if the condition was not present on admission.

Question 7: A CDS reviews a record with clinical indicators of sepsis (fever, tachycardia, leukocytosis, and a positive blood culture) but the physician has only documented 'UTI'. Which query statement is the most compliant?

Based on the documented fever, tachycardia, leukocytosis, and positive blood culture, can you please clarify a diagnosis that represents these findings? (Correct answer)
Please document sepsis as it is clearly supported by the clinical evidence in the chart.
Per sepsis-3 criteria, this patient meets the definition. Please clarify the diagnosis.
Do you agree the patient has sepsis secondary to UTI based on the fever, tachycardia, and positive blood culture?

Correct answer: Based on the documented fever, tachycardia, leukocytosis, and positive blood culture, can you please clarify a diagnosis that represents these findings?

This query is compliant because it presents the objective clinical indicators from the record and asks the physician to provide a diagnosis based on their professional judgment without leading them to a specific answer. Options A and C are leading, and option B introduces information not present in the scenario.

Question 8: Why is it important for CDI specialists to query for a specific type of acute kidney injury rather than accepting 'acute kidney failure, unspecified'?

Stage-specific AKI codes have no impact on MS-DRG assignment
Unspecified AKI always defaults to MCC status under MS-DRG grouping
Staging is only required for CKD documentation, not AKI
Specific AKI types such as tubular necrosis are MCCs while unspecified AKI is only a CC (Correct answer)

Correct answer: Specific AKI types such as tubular necrosis are MCCs while unspecified AKI is only a CC

N17.0 (tubular necrosis) is classified as an MCC while N17.9 (unspecified AKI) is only a CC, meaning specificity directly impacts MS-DRG weight and reimbursement.

Question 9: Which documentation standard requires that every medical record entry be dated, timed, and authenticated by the responsible provider?

CMS MS-DRG Definitions Manual
The Joint Commission (TJC) Medical Record Standards (Correct answer)
ICD-10-CM Official Coding Guidelines
AHIMA Standards of Ethical Coding

Correct answer: The Joint Commission (TJC) Medical Record Standards

The Joint Commission's medical record standards require that all entries in the medical record be dated, timed, and authenticated (signed) by the responsible provider.

Question 10: In a post-discharge CDI review, a specialist finds that septic shock was documented only in nursing notes but not by the physician. What is the appropriate action?

Ignore the nursing note as it has no coding significance
Query the physician post-discharge to clarify whether septic shock was present (Correct answer)
Add septic shock to the secondary diagnosis list without a query
Code septic shock based on the nursing note documentation

Correct answer: Query the physician post-discharge to clarify whether septic shock was present

Only physician or qualified provider documentation can be used as the basis for coding diagnoses. If septic shock is documented only in nursing notes, a post-discharge query to the attending or responsible physician is required.

Question 11: Under the Two-Midnight Rule, which physician documentation element is MOST critical to support an inpatient admission?

The patient's out-of-pocket cost estimate and financial counseling note
The number of procedures performed during the stay
The admitting physician's documented expectation that care will span at least two midnights (Correct answer)
The patient's insurance type and pre-authorization number

Correct answer: The admitting physician's documented expectation that care will span at least two midnights

The Two-Midnight Rule requires that the admitting physician document a reasonable expectation that the patient will require hospital care spanning two midnights.

Question 12: What does a high CC and MCC capture rate indicate about a CDI program?

The CDI program is effectively identifying and documenting secondary diagnoses (Correct answer)
The hospital treats a disproportionate share of Medicare patients
The hospital is upcoding claims inappropriately
The average length of stay is artificially inflated

Correct answer: The CDI program is effectively identifying and documenting secondary diagnoses

A high CC/MCC capture rate reflects that the CDI program is successfully identifying and ensuring documentation of significant secondary diagnoses that affect patient severity and resource utilization.

Question 13: In data analysis for CDI, 'specificity' of a coded diagnosis most directly affects:

MS-DRG assignment and reimbursement accuracy (Correct answer)
The patient's length of stay
Nursing staff workload
The number of queries issued per record

Correct answer: MS-DRG assignment and reimbursement accuracy

Diagnosis specificity determines the ICD-10-CM code selected, which drives MS-DRG grouping and corresponding reimbursement.

Question 14: According to ICD-10-CM guidelines, what relationship is assumed between hypertension and chronic kidney disease when both are documented?

Hypertension and CKD are coded separately as unrelated conditions
A causal relationship is assumed, requiring combination codes from category I12 (Correct answer)
The physician must explicitly state that hypertension caused the CKD before linking them
Hypertension is coded as a complication of CKD rather than its cause

Correct answer: A causal relationship is assumed, requiring combination codes from category I12

ICD-10-CM presumes a causal relationship between hypertension and CKD, requiring combination codes from category I12 without explicit provider documentation of causality.

Question 15: Which of the following is a key benefit of effective CDI programs?

Improved coding accuracy and reimbursement (Correct answer)
Decreased patient satisfaction scores
Reduced staff training needs
Increased patient wait times

Correct answer: Improved coding accuracy and reimbursement

Effective CDI programs yield several key benefits, most notably improved coding accuracy and reimbursement. When clinical documentation is precise and complete, it allows coders to assign the most accurate diagnostic and procedural codes, which directly impacts the financial integrity of healthcare organizations. Furthermore, it supports compliance, enhances data quality for analytics, and provides a clearer picture of patient care.

Question 16: Which of the following statements about query timing is MOST accurate under compliant query practices?

Queries may be issued concurrently during the encounter or retrospectively after discharge (Correct answer)
Queries must only be submitted after the patient is discharged to avoid influencing care
Queries are not permitted once a final bill has been submitted to the payer
Queries should be issued only at admission to capture the principal diagnosis early

Correct answer: Queries may be issued concurrently during the encounter or retrospectively after discharge

Both concurrent (during admission) and retrospective (post-discharge) queries are permissible under compliant query guidelines.

Question 17: A patient is admitted with decompensated heart failure and develops AKI from reduced renal perfusion. Which query format is most appropriate for the CDI specialist?

No query is needed since the etiology of AKI is clinically evident from the heart failure diagnosis
A yes/no query asking only if the patient has AKI
A multiple-choice compliant query offering pre-renal AKI, intrinsic AKI, and other clinically appropriate alternatives (Correct answer)
A leading query that directly suggests the AKI is cardiorenal syndrome caused by heart failure

Correct answer: A multiple-choice compliant query offering pre-renal AKI, intrinsic AKI, and other clinically appropriate alternatives

AHIMA and ACDIS guidelines require compliant queries to offer multiple clinically reasonable options without leading the provider toward a predetermined response.

Question 18: Which documented condition, if present alongside AKI, would most likely result in an MS-DRG upgrade reflecting greater patient resource intensity?

Asymptomatic urinary tract infection
Urinary retention requiring catheterization
Acute kidney injury with tubular necrosis, classified as an MCC (Correct answer)
Incidental asymptomatic hematuria

Correct answer: Acute kidney injury with tubular necrosis, classified as an MCC

AKI with tubular necrosis (N17.0) is classified as an MCC, which can significantly increase the MS-DRG weight compared to conditions classified as CCs or non-CCs.

Question 19: A physician responds to a query by writing 'per CDI' next to a newly added diagnosis. The CDI specialist should:

Ask the physician to re-document using their own clinical judgment without referencing the CDI query (Correct answer)
Code the diagnosis as documented because any physician attestation is sufficient
Route the chart to compliance for automatic review since the physician responded
Accept the response because the physician did sign the entry, making it legally valid

Correct answer: Ask the physician to re-document using their own clinical judgment without referencing the CDI query

Physician responses must reflect their own independent clinical judgment; 'per CDI' suggests the documentation may not meet compliance standards.

Question 20: Which quality metric measures the rate of complications that could reasonably have been prevented through optimal care?

Case Mix Index (CMI)
Patient Safety Indicators (PSIs) (Correct answer)
Geometric Mean Length of Stay (GMLOS)
Average Length of Stay (ALOS)

Correct answer: Patient Safety Indicators (PSIs)

Patient Safety Indicators (PSIs) are AHRQ-developed metrics that flag potentially preventable complications and adverse events during hospitalization. CDI specialists monitor PSIs because incomplete documentation can cause avoidable PSI flags that negatively impact hospital quality scores.

Question 21: A patient undergoes cardiac catheterization revealing 70% LAD stenosis. The cardiologist documents 'significant CAD.' What should the CDI specialist consider?

Query to determine if the CAD involves native versus bypass graft vessels and the number of vessels (Correct answer)
Accept 'significant CAD' and assign the unspecified CAD code
Query for acute MI since the stenosis is over 50%
Code coronary artery stenosis as the principal diagnosis

Correct answer: Query to determine if the CAD involves native versus bypass graft vessels and the number of vessels

ICD-10-CM codes for CAD differentiate by vessel type (native/graft), number of vessels, and presence of angina, requiring specificity beyond 'significant CAD.'

Question 22: Which of the following is a key component of effective healthcare documentation?

Limited use of medical terminology
Vague descriptions of patient conditions
Detailed, accurate, and timely entries (Correct answer)
Delayed recording of patient interactions

Correct answer: Detailed, accurate, and timely entries

Effective healthcare documentation relies on detailed, accurate, and timely entries that clearly communicate the patient's condition, care provided, and outcomes. Vague descriptions, delayed recording, or limited use of medical terminology can lead to misinterpretations, errors in care, and inaccurate coding. High-quality documentation ensures clarity, consistency, and reliability of patient information.

Question 23: Which MS-DRG grouping logic feature allows a single DRG to shift to a higher-weighted DRG when a qualifying OR procedure is present?

CC/MCC subclassification
Procedure intensity scoring
OR procedure designation (Correct answer)
MDC assignment

Correct answer: OR procedure designation

OR (operating room) procedure designation triggers MS-DRG logic to route a case to surgical DRGs, which typically carry higher relative weights than medical DRGs.

Question 24: Which compliance framework do hospitals use to structure internal CDI and coding compliance programs?

The CMS Conditions of Participation for Medical Records
The Joint Commission ORYX Performance Measurement System
The OIG Seven Elements of an Effective Compliance Program (Correct answer)
The UHDDS Data Element Reporting Requirements

Correct answer: The OIG Seven Elements of an Effective Compliance Program

The OIG's Seven Elements of an Effective Compliance Program provide the foundational structure for hospital compliance programs, including CDI and coding compliance.

Question 25: The Uniform Hospital Discharge Data Set (UHDDS) provides official definitions for which of the following?

Principal diagnosis and other diagnoses (Correct answer)
Sepsis-3 clinical criteria
Hospital-Acquired Conditions (HACs)
Appropriate use of physician queries

Correct answer: Principal diagnosis and other diagnoses

The UHDDS was established to create a standardized system for collecting hospital data. It provides the core definitions for principal diagnosis, other (secondary) diagnoses, and significant procedures, which are foundational to inpatient coding and reporting.

Question 26: Under AHIMA's 2019 compliant query guidelines, which of the following must be included in every written query?

Physician's DEA number, patient insurance ID, and estimated MS-DRG impact
The CDI specialist's credentials and the anticipated reimbursement change
A signature line for the physician to attest to medical necessity
Patient name, account number or date of service, and the clinical indicators supporting the query (Correct answer)

Correct answer: Patient name, account number or date of service, and the clinical indicators supporting the query

AHIMA guidelines require patient identifiers, relevant clinical indicators, and a clear question with balanced response options.

Question 27: What is the clinical documentation and reimbursement significance of 'acute on chronic heart failure'?

It carries a higher DRG weight than chronic heart failure alone and has its own specific ICD-10-CM code (Correct answer)
It has no reimbursement impact compared to chronic heart failure
It is not a recognized ICD-10-CM diagnostic term
It results in a lower DRG weight due to chronic disease adjustment

Correct answer: It carries a higher DRG weight than chronic heart failure alone and has its own specific ICD-10-CM code

Acute on chronic heart failure has a specific ICD-10-CM code and typically results in a higher-weighted DRG compared to chronic heart failure alone, reflecting the increased resource utilization.

Question 28: A patient is documented with 'hypertensive heart disease with heart failure.' Under ICD-10-CM, what is the coding convention that applies?

Hypertension and heart failure must be coded separately unless the physician explicitly links them
Heart failure is coded as the principal diagnosis and hypertension as a secondary condition without a combination code
The combination code only applies when systolic heart failure is documented
A cause-and-effect relationship between hypertension and heart failure is assumed and coded with a combination code (Correct answer)

Correct answer: A cause-and-effect relationship between hypertension and heart failure is assumed and coded with a combination code

ICD-10-CM presumes a causal relationship between hypertension and heart failure, requiring use of the hypertensive heart disease with heart failure combination code.

Question 29: Which CKD stage corresponds to a GFR of 15–29 mL/min/1.73m²?

Stage 4 (Correct answer)
Stage 3a
Stage 3b
Stage 5

Correct answer: Stage 4

CKD Stage 4 is defined by a GFR of 15–29 mL/min/1.73m², representing severely decreased kidney function approaching end-stage disease.

Question 30: A patient develops a catheter-associated urinary tract infection (CAUTI) on the third day of their hospital stay. What is the correct Present on Admission (POA) indicator for this diagnosis?

Y (Yes, present on admission)
W (Clinically undetermined)
N (No, not present on admission) (Correct answer)
U (Unknown, documentation insufficient)

Correct answer: N (No, not present on admission)

The POA indicator 'N' signifies that the condition was not present at the time of inpatient admission. Since the CAUTI developed after admission, 'N' is the correct indicator.

Question 31: A query is sent to a physician asking: 'Do you agree the patient has sepsis?' This query is problematic primarily because it:

Does not include the patient's MRN in the query header
Should have been sent to the attending of record, not the treating physician
Is a leading yes/no query that suggests a specific diagnosis without balanced options (Correct answer)
Uses the word 'agree,' which is not a recognized medical term

Correct answer: Is a leading yes/no query that suggests a specific diagnosis without balanced options

Leading yes/no queries that suggest a specific answer are non-compliant because they bias the physician's response.

Question 32: A CDI specialist is training new staff on query language. Which of the following phrases is MOST appropriate to include in a compliant query?

'Documentation of malnutrition would more accurately reflect the care provided and improve reimbursement.'
'Based on the following clinical indicators, can you clarify or further specify the patient's condition?' (Correct answer)
'Please confirm the diagnosis of septic shock to support accurate MS-DRG assignment.'
'The current documentation does not support the level of care billed; please revise accordingly.'

Correct answer: 'Based on the following clinical indicators, can you clarify or further specify the patient's condition?'

A compliant query asks for clarification based on clinical evidence without suggesting a specific outcome or mentioning financial impact.

Question 33: What is the role of a Clinical Documentation Specialist (CDS) in relation to clinical coding?

To handle administrative tasks unrelated to clinical documentation
To ensure that clinical documentation supports accurate coding and billing (Correct answer)
To provide patient financial assistance
To manage patient care directly

Correct answer: To ensure that clinical documentation supports accurate coding and billing

A Clinical Documentation Specialist (CDS) plays a vital role in ensuring that clinical documentation accurately and completely supports the clinical codes assigned for billing and data analysis. They review patient records to identify any gaps or inconsistencies that could lead to incorrect coding. By querying physicians for clarification, the CDS helps to ensure that the documentation reflects the true severity of illness and complexity of care, thereby optimizing coding accuracy and reimbursement.

Question 34: A physician uses the term 'urosepsis' in documentation. How should a CDI specialist respond?

Code as sepsis due to urinary tract infection directly
Query the physician to clarify whether a UTI, sepsis due to UTI, or another condition is intended (Correct answer)
Accept the term and code as unspecified sepsis (A41.9)
Document that urosepsis is the principal diagnosis without further review

Correct answer: Query the physician to clarify whether a UTI, sepsis due to UTI, or another condition is intended

The term 'urosepsis' is not a codeable ICD-10-CM term and has been used inconsistently to mean anything from a UTI to sepsis due to UTI. The CDI specialist must query the physician to clarify the intended clinical meaning before coding.

Question 35: Why is it important for healthcare documentation to be consistent across all providers involved in a patient’s care?

To ensure a unified understanding of the patient’s condition and treatment plan (Correct answer)
To limit access to patient information
To reduce the length of the medical record
To increase documentation redundancy

Correct answer: To ensure a unified understanding of the patient’s condition and treatment plan

It is crucial for healthcare documentation to be consistent across all providers involved in a patient’s care to ensure a unified understanding of the patient’s condition and treatment plan. Inconsistent documentation can lead to miscommunication, errors in care, and fragmented treatment approaches. Consistency promotes patient safety, facilitates care coordination, and supports accurate data for billing and quality improvement.

Question 36: Which action by a CDI specialist most likely constitutes 'query harassment' under professional guidelines?

Querying a physician about a diagnosis that appears in only one progress note
Sending a query that covers two related conditions on the same form
Using a query template that was not approved by the facility's compliance committee
Sending repeated queries to the same physician on the same encounter after receiving a 'clinically undetermined' response (Correct answer)

Correct answer: Sending repeated queries to the same physician on the same encounter after receiving a 'clinically undetermined' response

Requerying a physician on the same issue after receiving a valid 'clinically undetermined' response is considered query harassment and is non-compliant.

Question 37: Which OIG program provides annual guidance on high-risk healthcare compliance areas including CDI and coding?

Medicare Administrative Contractor (MAC) Local Coverage Determinations
CMS PEPPER reports
Recovery Audit Contractor (RAC) denial trend reports
OIG Work Plan and annual compliance program guidance (Correct answer)

Correct answer: OIG Work Plan and annual compliance program guidance

The OIG Work Plan, published annually, identifies high-risk areas for fraud and abuse including CDI-related issues such as inpatient admission criteria, DRG upcoding, and specific diagnosis documentation.

Question 38: A discharge summary that conflicts with the body of the medical record should be handled in which of the following ways?

Code based on whichever documentation supports the higher DRG
Query the physician to resolve the discrepancy before finalizing the coded record (Correct answer)
Always defer to the discharge summary as the most authoritative document
Use the conflicting information to code two separate diagnoses

Correct answer: Query the physician to resolve the discrepancy before finalizing the coded record

When the discharge summary contradicts information in the body of the record, the physician should be queried to clarify and reconcile the conflict before coding.

Question 39: Which data visualization method is most effective for showing the trend of a hospital's CMI over 12 consecutive months?

Scatter plot
Run chart (Correct answer)
Pie chart
Histogram

Correct answer: Run chart

A run chart displays a single metric over time, making it ideal for tracking CMI trends across months.

Question 40: In the CMS-HCC model, a patient's chronic conditions must be re-documented each plan year to be included in the risk score. This requirement is best described as:

Hierarchical condition coding
Annual recapture (Correct answer)
Concurrent review
Prospective documentation

Correct answer: Annual recapture

Annual recapture means that HCCs do not carry forward automatically from prior years — each condition must be documented in the current measurement year for it to affect the risk score. This drives the CDI and coding focus on re-documenting chronic conditions at every relevant encounter.

Question 41: Which ICD-10-CM code is assigned for end-stage renal disease (ESRD) requiring renal replacement therapy?

N18.6 (Correct answer)
N17.9
N18.5
N19

Correct answer: N18.6

N18.6 is the specific ICD-10-CM code for ESRD, which is distinct from N18.5 (CKD Stage 5) and indicates dependency on dialysis or other renal replacement therapy.

Question 42: A patient with congestive heart failure has significant peripheral edema and a stable weight, but also has visible temporal wasting and poor grip strength. How should the CDS proceed?

Recommend a nutrition consult without querying for a diagnosis.
Focus only on the congestive heart failure diagnosis.
Conclude that malnutrition cannot be diagnosed due to the stable weight.
Query the provider to assess for malnutrition based on muscle loss and functional status. (Correct answer)

Correct answer: Query the provider to assess for malnutrition based on muscle loss and functional status.

Fluid accumulation can easily mask true weight loss from muscle and fat depletion. The CDS should query the provider to evaluate for malnutrition using the other clinical criteria that are present, such as loss of muscle mass (temporal wasting) and diminished functional status (grip strength).

Question 43: Which of the following CMS-designated HACs requires a POA indicator of 'N' to affect MS-DRG payment?

Type 2 diabetes mellitus
Chronic kidney disease stage 3
Catheter-associated urinary tract infection (CAUTI) (Correct answer)
Community-acquired pneumonia

Correct answer: Catheter-associated urinary tract infection (CAUTI)

CAUTI is a CMS-designated HAC, and when the POA indicator is 'N', it triggers the HAC payment adjustment.

Question 44: A patient is admitted for total knee replacement (TKR) and is transferred to the ICU post-operatively for respiratory failure requiring mechanical ventilation for 96 or more hours and a tracheostomy. How does this change the DRG?

Mechanical ventilation duration has no impact on DRG assignment for surgical cases
The case shifts to MDC 4 with the knee replacement as additional procedure
The mechanical ventilation duration and tracheostomy may shift the case to a pre-MDC respiratory DRG (Correct answer)
The case stays in the orthopedic surgical DRG with the respiratory failure added as an MCC

Correct answer: The mechanical ventilation duration and tracheostomy may shift the case to a pre-MDC respiratory DRG

Mechanical ventilation for 96 or more hours combined with a tracheostomy triggers a pre-MDC DRG assignment. This pre-MDC classification overrides the orthopedic MDC assignment.

Question 45: Under KDIGO staging, a patient whose urine output drops to 0.3 mL/kg/hr for 20 consecutive hours would be classified as which AKI stage?

Chronic kidney disease exacerbation
AKI Stage 3 (Correct answer)
AKI Stage 1
AKI Stage 2

Correct answer: AKI Stage 3

KDIGO Stage 3 AKI includes urine output less than 0.3 mL/kg/hr for ≥12 hours or anuria for ≥12 hours.

Question 46: Which of the following tools is commonly used for analyzing clinical documentation data?

Spreadsheet software
All of the above (Correct answer)
Database management systems
Electronic Health Record (EHR) system

Correct answer: All of the above

Analyzing clinical documentation data often requires a combination of tools to extract, process, and visualize information. Electronic Health Record (EHR) systems are the primary source of this data, while spreadsheet software is useful for basic analysis and visualization. Database management systems are crucial for handling large volumes of structured data, making 'All of the above' the correct choice as these tools collectively support comprehensive data analysis.

Question 47: A patient undergoes a laparoscopic cholecystectomy that is converted to an open procedure. How should this be coded in ICD-10-PCS?

Code the procedure as percutaneous endoscopic converted to open with a single code
Code both the laparoscopic and open approaches with separate PCS codes
Code only the open approach since it was the completed procedure (Correct answer)
Code only the laparoscopic approach since it was the intended approach

Correct answer: Code only the open approach since it was the completed procedure

Per ICD-10-PCS guidelines, when a procedure is converted from a laparoscopic to an open approach, only the open approach procedure code is assigned. The laparoscopic portion that did not complete the intended procedure is not separately coded.

Question 48: Which of the following is considered a 'qualified provider' who may document diagnoses for ICD-10-CM coding purposes in the inpatient setting?

Registered nurse documenting in the nursing care plan
Attending physician or other qualified healthcare practitioner legally accountable for the patient's care (Correct answer)
Pharmacist documenting in the medication reconciliation record
Physical therapist documenting in the rehabilitation notes

Correct answer: Attending physician or other qualified healthcare practitioner legally accountable for the patient's care

Per ICD-10-CM guidelines, diagnoses must be documented by the attending physician or other qualified healthcare practitioners who are legally accountable for establishing diagnoses in the inpatient setting.

Question 49: A quality analyst reports that the hospital's risk-adjusted complication rate appears elevated compared to peers. What CDI-related factor should be investigated first?

Whether physicians are using electronic order sets
Whether nursing documentation matches physician notes
Whether POA indicators are being assigned accurately for all secondary diagnoses (Correct answer)
Whether the hospital is billing for all procedures performed

Correct answer: Whether POA indicators are being assigned accurately for all secondary diagnoses

Inaccurate POA indicator assignment can cause conditions present before admission to be counted as hospital-acquired complications, artificially inflating the risk-adjusted complication rate.

Question 50: A hospitalist documents 'sepsis secondary to C. difficile colitis.' Which ICD-10-CM code combination is correct?

R65.20, A04.72
A41.9, A04.72 (Correct answer)
A04.72, A41.9
A41.9 alone (C. diff is integral)

Correct answer: A41.9, A04.72

ICD-10-CM guidelines sequence sepsis (A41.9) first when it is the principal diagnosis, followed by the underlying infection (A04.72 for C. diff colitis).

Question 51: A patient has a PaO2 of 58 mmHg on 4L nasal cannula and a respiratory rate of 28. The physician's assessment is 'hypoxia'. What type of query would be most appropriate?

A query asking the physician to document 'acute hypoxic respiratory failure'.
A query presenting the clinical indicators and asking if a more specific diagnosis can be made. (Correct answer)
No query is needed as 'hypoxia' is a sufficient diagnosis.
A query asking to increase the patient's oxygen level.

Correct answer: A query presenting the clinical indicators and asking if a more specific diagnosis can be made.

The clinical indicators (low PaO2 despite supplemental oxygen, tachypnea) are strongly suggestive of acute respiratory failure. The term 'hypoxia' is a symptom, not a definitive diagnosis. A query is needed to ask the physician if these clinical findings represent a more significant diagnosis like acute respiratory failure.

Question 52: Under the Uniform Hospital Discharge Data Set (UHDDS) guidelines, when should AKI be coded as a secondary diagnosis?

When the physician lists it in the problem list but not the discharge summary
When it affects patient care, requires clinical evaluation, or prolongs the length of stay (Correct answer)
Only when it is the primary reason for admission
Only when dialysis is performed during the encounter

Correct answer: When it affects patient care, requires clinical evaluation, or prolongs the length of stay

UHDDS defines additional diagnoses as conditions that affect patient care in terms of requiring clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of stay, or increased nursing care and monitoring.

Question 53: Which of the following would be considered a reportable secondary diagnosis?

A condition mentioned in the ED note but not addressed again.
A family history of colon cancer.
Chronic hypertension managed with home medications that are continued during the stay. (Correct answer)
A resolved case of pneumonia from two years ago.

Correct answer: Chronic hypertension managed with home medications that are continued during the stay.

According to UHDDS, a secondary diagnosis is a condition that coexists at admission or develops subsequently, and affects patient care in terms of requiring clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of stay, or increased nursing care/monitoring.

Question 54: A CDS specialist identifies a statistically significant correlation (r = 0.82) between query volume and CMI improvement. What is the most important caveat to communicate when presenting this finding?

The r-value is too low to be meaningful
Correlation does not imply causation (Correct answer)
CMI is not a valid outcome measure
Query volume should be reduced to test the relationship

Correct answer: Correlation does not imply causation

Even a strong correlation cannot confirm that increased queries caused CMI improvement without controlling for confounding variables.

Question 55: Which CMS value-based purchasing program penalizes hospitals for excess readmissions within 30 days for specific conditions?

Merit-Based Incentive Payment System
Hospital-Acquired Condition Reduction Program
Hospital Value-Based Purchasing Program
Hospital Readmissions Reduction Program (Correct answer)

Correct answer: Hospital Readmissions Reduction Program

The Hospital Readmissions Reduction Program (HRRP) reduces Medicare payments to hospitals with excess 30-day readmissions for conditions such as AMI, heart failure, and pneumonia.

Question 56: When a STEMI is treated with percutaneous coronary intervention (PCI), what documentation must the CDI specialist verify for complete procedure coding?

Both the specific coronary artery involved and the stent type used (Correct answer)
Documentation of the specific coronary artery only
Neither — the STEMI diagnosis code is sufficient
Documentation of the stent type only

Correct answer: Both the specific coronary artery involved and the stent type used

Accurate STEMI procedure coding requires documentation of the specific coronary artery and the type of stent (drug-eluting vs. bare-metal) to assign the correct ICD-10-PCS procedure code.

Question 57: A CDS program tracks 'initial query rate' as the number of queries issued divided by the number of records reviewed. This metric primarily measures:

Program efficiency
Documentation opportunity identification (Correct answer)
Physician compliance
Coder productivity

Correct answer: Documentation opportunity identification

The initial query rate reflects how often reviewers identify a documentation opportunity requiring clarification per record reviewed.

Question 58: A CDI specialist identifies that a patient with an open wound has documentation of 'possible osteomyelitis.' Under inpatient coding guidelines, how should this be coded?

It should be coded as a wound infection instead
It should be coded as osteomyelitis per the uncertain diagnosis guideline (Correct answer)
It cannot be coded; only confirmed diagnoses are coded
It should be flagged as a query but left uncoded pending confirmation

Correct answer: It should be coded as osteomyelitis per the uncertain diagnosis guideline

Under ICD-10-CM Official Coding Guidelines for inpatient settings, conditions documented as 'possible,' 'probable,' 'suspected,' or similar uncertainty terms at the time of discharge may be coded as if confirmed.

Question 59: A patient admitted for pneumonia also undergoes diagnostic bronchoscopy with bronchoalveolar lavage. Which procedure is the principal procedure?

Bronchoscopy with BAL, because it is the only procedure performed
The procedure directly treating the principal diagnosis (none here, so bronchoscopy by default) (Correct answer)
Bronchoscopy with BAL only if it changes the final diagnosis
There is no principal procedure when only a diagnostic procedure is done

Correct answer: The procedure directly treating the principal diagnosis (none here, so bronchoscopy by default)

When no therapeutic procedure is performed, the diagnostic procedure most related to the principal diagnosis is designated the principal procedure.

Question 60: A CDI specialist wants to query about the specificity of a patient's anemia. Which query format is MOST compliant with AHIMA/ACDIS guidelines?

A multiple-choice query listing anemia types with a blank for 'other' and 'clinically undetermined' (Correct answer)
A verbal question asking the physician to pick the correct anemia type from a list read aloud
A leading statement suggesting 'iron deficiency anemia appears most consistent with labs'
A yes/no query asking if the patient has iron deficiency anemia

Correct answer: A multiple-choice query listing anemia types with a blank for 'other' and 'clinically undetermined'

A multiple-choice format with 'clinically undetermined' as an option is the compliant standard per AHIMA/ACDIS query guidelines.

Question 61: A CDI specialist notices the hospital's Case Mix Index (CMI) dropped after a coding software update. What is the MOST likely explanation?

Increased patient volume lowered the average
The hospital admitted fewer complex patients
CMI calculations changed under the new fiscal year
Higher-severity DRGs are being under-coded due to documentation gaps (Correct answer)

Correct answer: Higher-severity DRGs are being under-coded due to documentation gaps

A drop in CMI typically signals that high-severity DRGs are not being captured, often because documentation does not support the specificity needed to assign more resource-intensive DRGs.

Question 62: When analyzing CC/MCC capture rates by physician, a CDI analyst finds that one physician has a significantly lower capture rate than peers. What is the MOST appropriate next step?

Conduct a focused chart review to determine if documentation gaps or coding issues are the cause (Correct answer)
Remove the physician from CDI monitoring
Immediately report the physician to compliance
Compare the physician's patient volume to peers before drawing conclusions

Correct answer: Conduct a focused chart review to determine if documentation gaps or coding issues are the cause

Before taking any action, the CDI analyst should conduct a focused review of the physician's charts to determine whether the low capture rate reflects documentation deficiencies, a legitimately less-complex patient mix, or coding issues.

Question 63: Which CDI strategy is MOST effective for improving documentation of malnutrition in hospitalized patients?

Relying on BMI thresholds alone to identify malnourished patients for coding
Reviewing dietary consultation notes and querying physicians when nutritional criteria are met (Correct answer)
Deferring malnutrition documentation to the discharge summary
Automatically adding malnutrition to the problem list when a dietitian documents it

Correct answer: Reviewing dietary consultation notes and querying physicians when nutritional criteria are met

The most effective strategy is reviewing dietitian consultation notes for documented nutritional criteria per ASPEN/AND guidelines and querying the attending physician to confirm or deny malnutrition as a diagnosis. Physician confirmation is required for coding.

Question 64: The UHDDS requires that secondary diagnoses be reported only when they affect patient care. Which of the following should NOT be reported?

Type 2 diabetes requiring insulin management during the stay
Chronic kidney disease affecting medication dosing decisions
Hypertension managed with continued home medications during the hospitalization
A historical finding documented as 'history of appendectomy 10 years ago' (Correct answer)

Correct answer: A historical finding documented as 'history of appendectomy 10 years ago'

A 'history of appendectomy' is a past procedure with no active management implications during the current stay. Historical conditions that do not affect current patient care, treatment, or monitoring do not meet the UHDDS reporting standard.

Question 65: Which element is REQUIRED to be included in every compliant physician query?

The identity of the insurance payer for the case
The specific ICD-10-CM code the CDI specialist is seeking
Clinical indicators from the medical record that prompted the query (Correct answer)
The DRG impact of the physician's potential response

Correct answer: Clinical indicators from the medical record that prompted the query

Every compliant query must cite the specific clinical indicators from the medical record that prompted the question. This demonstrates that the query is clinically based and not financially motivated.

Question 66: Which ICD-10-CM/PCS coding guideline requires a CDI specialist to distinguish between a malignant neoplasm and a personal history of cancer when reviewing documentation?

Guideline on neoplasm coding and sequencing (Correct answer)
Guideline on signs and symptoms
Guideline on combination codes
Guideline on chronic conditions

Correct answer: Guideline on neoplasm coding and sequencing

ICD-10-CM neoplasm guidelines specify distinct codes for active malignancies versus personal history of cancer, which significantly impacts severity scoring and quality metrics.

Question 67: Which type of query is considered MOST efficient for obtaining a specific documentation clarification with multiple possible answers?

Yes/no query
Multiple-choice query (Correct answer)
Open-ended query
Verbal query with written follow-up

Correct answer: Multiple-choice query

Multiple-choice queries are the most efficient format for clarifications with several plausible diagnoses because they provide the physician with organized options based on clinical indicators.

Question 68: What is the primary purpose of the Medicare 'Two-Midnight Rule'?

To set a maximum length of stay for a given diagnosis.
To determine if a hospital stay should be paid as inpatient (Part A) or outpatient (Part B). (Correct answer)
To define the criteria for medical necessity of a surgical procedure.
To mandate that all patients must be discharged after two midnights.

Correct answer: To determine if a hospital stay should be paid as inpatient (Part A) or outpatient (Part B).

The Two-Midnight Rule is a policy that guides admitting physicians on when to admit a patient as an inpatient. It generally considers a hospital stay spanning two midnights to be appropriate for inpatient payment under Medicare Part A.

Question 69: Which statistical measure is most appropriate for describing the central tendency of a skewed distribution of patient length-of-stay data?

Mode
Mean
Range
Median (Correct answer)

Correct answer: Median

The median is preferred over the mean for skewed distributions because it is not distorted by extreme outliers.

Question 70: A patient develops sepsis 72 hours after hip arthroplasty. Which POA indicator applies to the sepsis diagnosis?

N – not present on admission (Correct answer)
U – documentation insufficient to determine
W – clinically undetermined
Y – present on admission

Correct answer: N – not present on admission

Sepsis developing 72 hours post-admission was not present on admission and should be assigned POA indicator 'N'.

Question 71: Under the Uniform Hospital Discharge Data Set (UHDDS), the principal diagnosis is defined as the condition established after study to be chiefly responsible for what?

Generating the highest MS-DRG weight
The highest-cost procedure performed
The patient's longest length of stay
Occasioning the admission to the hospital (Correct answer)

Correct answer: Occasioning the admission to the hospital

UHDDS defines the principal diagnosis as the condition established after study to be chiefly responsible for occasioning the patient's admission.

Question 72: The ICD-10-CM guideline for 'code also' notes instructs the coder to:

Sequence the 'code also' code as the principal diagnosis
Always assign both codes in the stated order
Assign the 'code also' code only when it affects treatment or management
Assign the 'code also' code only if the condition is documented as present (Correct answer)

Correct answer: Assign the 'code also' code only if the condition is documented as present

'Code also' notes indicate that a second code may be needed if the underlying condition is documented; if not documented, only the primary code is assigned.

Question 73: What is the key difference in documentation required for coding 'acute on chronic hypercapnic respiratory failure' versus 'chronic hypercapnic respiratory failure'?

Documentation of an acute worsening or decompensation from the patient's baseline respiratory status. (Correct answer)
Documentation of any pCO2 level above 45 mmHg.
A physician's note simply stating the patient has a history of COPD.
The patient's use of home oxygen.

Correct answer: Documentation of an acute worsening or decompensation from the patient's baseline respiratory status.

To support the 'acute on chronic' diagnosis, there must be documentation of an acute exacerbation or decompensation from the patient's baseline state. This is typically evidenced by an acute worsening of blood gases (e.g., a significant rise in pCO2 from baseline), increased respiratory distress, or a new precipitating event like pneumonia.

Question 74: Which Joint Commission standard most directly addresses the completeness of medical record documentation?

LD.04.01.01 — Leadership accountability standards
MM.01.01.03 — Medication management documentation
RC.01.01.01 — Medical record content and completion requirements (Correct answer)
PC.01.02.01 — Patient assessment standards

Correct answer: RC.01.01.01 — Medical record content and completion requirements

RC.01.01.01 requires that the medical record contain sufficient information to identify the patient, support the diagnosis, and justify the treatment.

Question 75: Which of the following best supports a CDI query for 'protein-calorie malnutrition' in a patient with a non-healing pressure ulcer?

BMI greater than 30 documented in the record
Hemoglobin of 11.5 g/dL
Albumin of 2.0 g/dL, pre-albumin of 10 mg/dL, dietitian note recommending nutritional supplementation (Correct answer)
Patient report of poor appetite for one week

Correct answer: Albumin of 2.0 g/dL, pre-albumin of 10 mg/dL, dietitian note recommending nutritional supplementation

Low albumin and pre-albumin combined with dietitian documentation of nutritional deficiency provides strong clinical indicators supporting a query for protein-calorie malnutrition as a contributing comorbidity.

Question 76: A patient is admitted with acute appendicitis and undergoes a laparoscopic appendectomy. A second procedure (colonoscopy for incidental polyp removal) is also performed. Which procedure should be designated as principal?

Laparoscopic appendectomy, as it directly treats the principal diagnosis (Correct answer)
Colonoscopy, as it is a more complex endoscopic procedure
The procedure performed first in the operating suite
Both procedures have equal claim to principal designation

Correct answer: Laparoscopic appendectomy, as it directly treats the principal diagnosis

The laparoscopic appendectomy directly treats acute appendicitis, the principal diagnosis. It should be designated as the principal procedure.

Question 77: Which of the following query scenarios represents an INAPPROPRIATE use of a physician query?

Querying to clarify the clinical significance of an abnormal laboratory finding
Querying to document sepsis when the only basis is a desire to capture an MCC (Correct answer)
Querying to confirm whether a wound infection meets criteria for postoperative wound dehiscence
Querying to clarify whether anemia is acute blood loss anemia versus iron deficiency anemia

Correct answer: Querying to document sepsis when the only basis is a desire to capture an MCC

Queries must be based on clinical indicators in the record, not on financial motivations. Sending a query to capture an MCC designation for sepsis without any clinical indicators supporting sepsis is non-compliant and potentially fraudulent.

Question 78: A patient is being weaned from mechanical ventilation using a spontaneous breathing trial (SBT). If the SBT fails, what CDI documentation opportunity arises?

Query for the underlying etiology causing weaning failure to ensure accurate diagnosis capture (Correct answer)
Document the failed SBT as a procedure complication
No CDI action is needed until extubation occurs
Assign a code for prolonged mechanical ventilation immediately

Correct answer: Query for the underlying etiology causing weaning failure to ensure accurate diagnosis capture

A failed SBT signals that the underlying condition (e.g., diaphragmatic weakness, cardiac dysfunction, COPD) may not be fully documented, making it a key CDI query opportunity.

Question 79: A CDS has sent two compliant, well-supported queries to a physician regarding the etiology of a patient's anemia, but has received no response. What is the most appropriate next step according to standard CDI practice?

Add a note in the chart stating 'Physician refused to clarify anemia etiology'.
Close the query as 'no response' and move on to the next chart.
Confront the physician in the hallway and demand an answer.
Follow the department's escalation policy, which may involve notifying the CDI manager or physician advisor. (Correct answer)

Correct answer: Follow the department's escalation policy, which may involve notifying the CDI manager or physician advisor.

A formal escalation process ensures that important documentation gaps are addressed while maintaining a professional and standardized approach. This usually involves a physician advisor who can engage the non-responsive physician in a peer-to-peer conversation.

Question 80: A patient develops a catheter-associated urinary tract infection (CAUTI) on day 4 of admission. Which piece of documentation is most critical for determining if this is a Hospital-Acquired Condition (HAC)?

The patient's age and gender.
Documentation of signs/symptoms of UTI being present on admission (POA). (Correct answer)
The specialty of the attending physician.
The type of antibiotic used to treat the infection.

Correct answer: Documentation of signs/symptoms of UTI being present on admission (POA).

The Present on Admission (POA) indicator is crucial for all HACs. If the signs/symptoms of the UTI were present when the patient was admitted, even if the formal diagnosis was made later, it would be considered POA and not a HAC.

Question 81: A CDI director is pressured by hospital administration to query physicians only when likely to result in a higher-weighted MS-DRG, regardless of whether clinical indicators support the query. This practice most directly violates:

The False Claims Act and the ACDIS/AHIMA Guidelines for Achieving a Compliant Query Practice (Correct answer)
The Stark Law prohibiting physician self-referral
The Emergency Medical Treatment and Labor Act (EMTALA)
The Joint Commission's documentation improvement standards

Correct answer: The False Claims Act and the ACDIS/AHIMA Guidelines for Achieving a Compliant Query Practice

Sending queries designed to drive a particular documentation outcome — rather than to clarify genuine clinical ambiguity — is a hallmark of a non-compliant query program. It can lead to unsupported diagnoses on claims, constituting false claims under the FCA. The ACDIS/AHIMA Practice Brief explicitly prohibits leading or biased queries intended to influence reimbursement.

Question 82: A CDI specialist is reviewing a case where the attending documents 'respiratory failure' but does not specify acute versus chronic. What should the CDI specialist do?

Code J96.00 as the default
Query the physician to specify acute, chronic, or acute-on-chronic respiratory failure (Correct answer)
Default to chronic respiratory failure as it is the safer, less severe option
Leave the diagnosis unspecified since both types have similar DRG weight

Correct answer: Query the physician to specify acute, chronic, or acute-on-chronic respiratory failure

Unspecified respiratory failure may map to a lower-complexity code or DRG. The CDI specialist should query the physician to specify whether failure is acute, chronic, or acute-on-chronic, as this distinction affects ICD-10-CM code assignment, MCC designation, and DRG weight.

Question 83: When querying about the type of heart failure, which response option MUST always be included in a compliant multiple-choice query?

Normal cardiac function
Congestive heart failure, unspecified
Acute-on-chronic systolic heart failure
Clinically undetermined (Correct answer)

Correct answer: Clinically undetermined

Every compliant multiple-choice query must include 'clinically undetermined' to allow the physician to indicate that the condition cannot be specified.

Question 84: A patient's record documents only 'diabetes mellitus.' To maximize appropriate HCC capture, what should the CDI specialist query for?

Whether the patient is on insulin alone
The type of diabetes (Type 1 vs. Type 2) and any associated complications such as CKD or neuropathy (Correct answer)
Whether diabetes was present on admission (POA status)
Whether the patient's A1c value is above or below 7.0

Correct answer: The type of diabetes (Type 1 vs. Type 2) and any associated complications such as CKD or neuropathy

HCC categories differentiate between diabetes types and complications. Type 2 diabetes with diabetic CKD, neuropathy, or other complications maps to higher-value HCC categories than uncomplicated diabetes. Specificity in type and complications is essential for accurate risk score calculation.

Question 85: A patient is admitted from the emergency department with sepsis. The admission note does not mention acute kidney injury (AKI), but labs drawn in the ED show an elevated creatinine. AKI is first diagnosed on day 2. What is the likely POA status of the AKI?

U (Unknown)
N (No)
Y (Yes) (Correct answer)
W (Clinically Undetermined)

Correct answer: Y (Yes)

The POA indicator applies to conditions present at the time of the inpatient admission order. Since the clinical indicators (elevated creatinine) were present from the ED visit immediately preceding admission, the AKI was present on admission, even though it was not diagnosed until later. The correct POA is 'Y'.

Question 86: When two surgical procedures are performed and either could serve as the principal procedure, what does the UHDDS guideline recommend?

Code both and let the grouper decide automatically
Always select the procedure with the longer operative time
Select the procedure with the higher relative weight
The facility may sequence them in any order, and the grouper selects the DRG with the highest weight (Correct answer)

Correct answer: The facility may sequence them in any order, and the grouper selects the DRG with the highest weight

UHDDS guidelines allow facilities to sequence multiple qualifying procedures in any order; the MS-DRG grouper evaluates all coded procedures and assigns the DRG that results in the highest relative weight.

Question 87: From a CDI perspective, why does accurate secondary diagnosis documentation have an even greater impact in APR-DRGs than in MS-DRGs?

APR-DRGs use secondary diagnoses to assign SOI and ROM subclasses, which directly affect the payment weight for each case (Correct answer)
MS-DRGs require more secondary diagnoses than APR-DRGs to assign correctly
APR-DRGs rely only on procedure codes to assign severity
Secondary diagnoses are not considered in either grouping system

Correct answer: APR-DRGs use secondary diagnoses to assign SOI and ROM subclasses, which directly affect the payment weight for each case

In APR-DRGs, each secondary diagnosis is evaluated for its contribution to SOI and ROM subclass assignment. A single well-documented comorbidity can elevate a case from SOI 2 (Moderate) to SOI 3 (Major), substantially changing expected resource use and reimbursement — an effect more granular than MS-DRG's binary MCC/CC distinction.

Question 88: In ICD-10-CM, the 'code first' instruction requires the coder to:

Assign the manifestation code before the etiology code
Assign the etiology code before the manifestation code (Correct answer)
Use the 'code first' code as an additional diagnosis only
Assign only the code marked 'code first' and exclude the other

Correct answer: Assign the etiology code before the manifestation code

The 'code first' instruction in ICD-10-CM indicates an etiology/manifestation coding convention where the etiology must be sequenced before the manifestation.

Question 89: When a wound care note describes 'serosanguineous drainage, moderate amount, periwound erythema' for a pressure ulcer, which documentation element is most important for the CDI specialist to verify is also captured by the physician?

Wound dimensions in centimeters
Clinical diagnosis of wound infection or cellulitis if clinically present (Correct answer)
Frequency of wound care treatments
Type of wound dressing applied

Correct answer: Clinical diagnosis of wound infection or cellulitis if clinically present

Periwound erythema and drainage may indicate infection or cellulitis; the physician must document a clinical diagnosis to support coding of a complication.

Question 90: A hospital's CDI program tracks 'query agreement rate.' A low agreement rate most likely indicates:

Physicians are confirming queried diagnoses at a high rate
Queries are being sent without adequate clinical support or are poorly formulated (Correct answer)
Coders are not reviewing query responses before assigning codes
The CDI program has an unusually complex patient population

Correct answer: Queries are being sent without adequate clinical support or are poorly formulated

A low query agreement rate where physicians frequently respond 'clinically undetermined' or disagree with the queried diagnosis suggests queries lack sufficient clinical support or are poorly constructed.

Question 91: What does the clinical term 'acute-on-chronic kidney disease' indicate for ICD-10-CM coding purposes?

AKI superimposed on pre-existing CKD, requiring codes for both conditions (Correct answer)
CKD that has recently advanced to a higher stage without an acute episode
A patient with CKD who has never experienced an acute kidney episode
A temporary improvement in CKD function following treatment

Correct answer: AKI superimposed on pre-existing CKD, requiring codes for both conditions

Acute-on-chronic kidney disease indicates AKI has developed in a patient with underlying CKD; ICD-10-CM requires assigning codes for both AKI (N17.x) and the appropriate CKD stage (N18.x).

Question 92: According to the ACDIS/AHIMA Guidelines for Achieving a Compliant Query Practice, which of the following best describes a compliant physician query?

A verbal query documented only in the CDI specialist's personal notes, not in the medical record
A query presenting clinical indicators from the record and asking the physician to clarify or confirm a diagnosis in an unbiased, open-ended or multiple-choice format (Correct answer)
A query sent only retrospectively after final coding is complete to avoid influencing care decisions
A query that suggests the diagnosis the hospital's CDI program needs to meet its case-mix index targets

Correct answer: A query presenting clinical indicators from the record and asking the physician to clarify or confirm a diagnosis in an unbiased, open-ended or multiple-choice format

A compliant query must be based on clinical indicators present in the record, be unbiased in format (not leading the physician toward a financially favorable answer), and be clearly documented as part of the medical record. Queries sent purely for reimbursement purposes or that suggest a specific answer violate the ACDIS/AHIMA Practice Brief and raise FCA risk.

Question 93: A CDI specialist is reviewing a patient with a BMI of 42 and the physician documents 'obesity.' What additional documentation should the CDI specialist query for?

Whether the patient has ever dieted
Morbid (severe) obesity or Class III obesity to reflect the clinical severity accurately (Correct answer)
The patient's weight loss goals
The patient's diet history

Correct answer: Morbid (severe) obesity or Class III obesity to reflect the clinical severity accurately

A BMI of 40 or greater qualifies as morbid (severe) obesity, and querying for this specificity affects DRG assignment and severity of illness reporting.

Question 94: How does the presence of a Major Complication or Comorbidity (MCC) most directly affect MS-DRG assignment compared to the presence of a CC?

MCCs and CCs affect the same DRG subgroup and differ only in reimbursement rate
MCCs shift the case to a higher-severity DRG with a greater relative weight than a CC would (Correct answer)
MCCs apply only to medical DRGs, not surgical DRGs
MCCs eliminate the need to code a principal procedure

Correct answer: MCCs shift the case to a higher-severity DRG with a greater relative weight than a CC would

MS-DRGs are subdivided into three severity levels—with MCC, with CC, and without CC/MCC—and the MCC subgroup carries the highest relative weight.

Question 95: In ICD-10-CM, which guideline governs how to code two conditions when a patient has both Type 2 diabetes mellitus and chronic kidney disease stage 3?

Query the physician to determine causal relationship
Code only the more severe condition
Use combination code E11.22 for diabetic CKD (Correct answer)
Assign separate codes for each condition independently

Correct answer: Use combination code E11.22 for diabetic CKD

ICD-10-CM provides combination code E11.22 (Type 2 diabetes mellitus with diabetic chronic kidney disease stage 3) that captures both conditions in a single code.

Question 96: What is the primary goal of a CDI mortality review?

To ensure the final coded data accurately reflects the patient's severity of illness and risk of mortality. (Correct answer)
To communicate with the patient's family about the hospital stay.
To determine the cause of death for the death certificate.
To assign blame for any potential medical errors.

Correct answer: To ensure the final coded data accurately reflects the patient's severity of illness and risk of mortality.

The main purpose of a mortality review from a CDI perspective is to ensure the documentation fully captures all active conditions and their severity. This leads to accurate coding that reflects the patient's true severity of illness (SOI) and risk of mortality (ROM), which is crucial for risk-adjusted mortality metrics.

Question 97: A CDS program wants to benchmark its query response rate against national standards. Which data source would provide the most relevant external comparison?

Internal facility historical data
State vital statistics records
ACDIS CDI industry survey benchmarks (Correct answer)
CMS cost reports

Correct answer: ACDIS CDI industry survey benchmarks

ACDIS publishes annual CDI industry surveys that provide national benchmarks for query response and agreement rates.

Question 98: A hospital receives a Targeted Probe and Educate (TPE) review notice from its MAC. What is the primary purpose of this review process?

To impose immediate financial penalties for billing errors
To refer providers with high error rates to the OIG for exclusion
To educate providers on proper billing and reduce error rates before enforcement (Correct answer)
To conduct unannounced on-site documentation audits

Correct answer: To educate providers on proper billing and reduce error rates before enforcement

TPE is an educational process in which MACs review a sample of claims, provide feedback, and offer education to help providers correct errors before stronger action is taken.

Question 99: Which approach BEST supports CDI success in capturing malnutrition documentation?

Waiting until discharge to query the physician about nutritional status
Querying only when the patient has a BMI below 18
Collaborating with dietitians to identify patients meeting malnutrition criteria and then querying the physician (Correct answer)
Coding malnutrition based on low albumin levels alone without a query

Correct answer: Collaborating with dietitians to identify patients meeting malnutrition criteria and then querying the physician

Interdisciplinary collaboration with dietitians helps CDI specialists identify malnutrition criteria (per ASPEN guidelines) and support timely, evidence-based physician queries.

Question 100: What is "data validation" in the context of clinical documentation?

Ensuring that data meets quality and accuracy standards (Correct answer)
Archiving old patient records
Converting data into different formats
The process of encrypting patient data

Correct answer: Ensuring that data meets quality and accuracy standards

Data validation in clinical documentation refers to the process of ensuring that the recorded information is accurate, complete, consistent, and adheres to established quality standards. This involves checking for errors, inconsistencies, and missing data points to maintain the integrity and reliability of patient records. High-quality data is essential for accurate coding, billing, patient care, and research.

Question 101: When is a 'Yes/No' query format considered non-compliant?

When confirming if a condition was present on admission.
When attempting to link two documented conditions (e.g., 'Is the hyponatremia due to the patient's SIADH?')
When asking the physician to establish a new diagnosis based on clinical indicators. (Correct answer)
When clarifying the acuity of a condition already documented (e.g., 'Is the heart failure acute?')

Correct answer: When asking the physician to establish a new diagnosis based on clinical indicators.

A 'Yes/No' query is non-compliant when it is used to establish a new diagnosis that has not been previously mentioned by the provider. This format can be perceived as leading the physician. It is best used for clarifying details of an already documented condition, such as acuity or linkage.

Question 102: A patient is admitted for pneumonia and also undergoes a screening colonoscopy during the stay, which was scheduled prior to admission. Which statement is correct regarding principal procedure selection?

The colonoscopy is the principal procedure because it is an invasive procedure.
There is no principal procedure as it was unrelated to the admission's principal diagnosis. (Correct answer)
The most expensive procedure performed is always the principal procedure.
The chest X-ray for pneumonia is the principal procedure.

Correct answer: There is no principal procedure as it was unrelated to the admission's principal diagnosis.

The colonoscopy is unrelated to the reason for admission (pneumonia). Therefore, there is no principal procedure for this encounter, and the case will be assigned a medical MS-DRG based on the pneumonia diagnosis.

Question 103: Which laboratory finding, when documented by the physician as clinically significant, most directly supports querying for hyperkalemia as a complication of AKI?

Serum potassium of 3.2 mEq/L with muscle cramps
Serum sodium of 128 mEq/L with confusion
BUN of 45 mg/dL with nausea
Serum potassium of 6.1 mEq/L with peaked T-waves on ECG (Correct answer)

Correct answer: Serum potassium of 6.1 mEq/L with peaked T-waves on ECG

A serum potassium of 6.1 mEq/L with ECG changes represents clinically significant hyperkalemia, a known complication of AKI due to impaired renal potassium excretion, warranting physician documentation and separate coding.

Question 104: A hospital's internal audit reveals that coders have been assigning a CC-designated secondary diagnosis code that is not clinically supported by physician documentation but is mentioned in nursing notes. This practice violates which standard?

UHDDS reporting requirements for secondary diagnoses
CMS MS-DRG Grouper calculation methodology
ICD-10-CM coding guideline requiring physician documentation to support diagnoses (Correct answer)
The Joint Commission medical record completion standards

Correct answer: ICD-10-CM coding guideline requiring physician documentation to support diagnoses

ICD-10-CM Official Guidelines require that diagnoses be documented by the attending physician or other qualified provider, not nursing staff. Using nursing notes alone to assign a secondary diagnosis code violates coding guidelines.

Question 105: Under the False Claims Act (FCA), which of the following scenarios could create liability for a hospital's CDI program?

Tracking query response rates and educating physicians on documentation specificity
Systematically sending leading queries that result in diagnoses not clinically supported, then submitting claims (Correct answer)
Using concurrent review to identify documentation gaps before discharge
Querying physicians about clinical indicators found in the medical record

Correct answer: Systematically sending leading queries that result in diagnoses not clinically supported, then submitting claims

Systematically sending leading or unsupported queries that result in non-clinically-supported diagnoses, then submitting Medicare claims for the resulting higher DRG, can constitute knowingly submitting false or fraudulent claims under the FCA.

Question 106: A patient is admitted with acute respiratory failure and pneumonia. The physician documents acute respiratory failure as the condition requiring the most intensive management. Per UHDDS and ICD-10-CM guidelines, what is the principal diagnosis?

Pneumonia, because it caused the respiratory failure
Acute respiratory failure, because it required the most resources (Correct answer)
Both conditions are co-principal and either may be sequenced first
Whichever condition the physician lists first in the H&P

Correct answer: Acute respiratory failure, because it required the most resources

When the attending physician identifies the condition requiring the most intensive management, that condition is selected as the principal diagnosis per UHDDS guidelines.

Question 107: A patient with severe heart failure has significant peripheral edema and ascites. How does this affect malnutrition assessment and documentation?

ICD-10-CM excludes malnutrition coding when significant fluid retention is present
Edema is a sign of adequate protein stores and argues against malnutrition
Fluid retention overestimates body weight, potentially masking weight loss from malnutrition (Correct answer)
Fluid retention increases muscle mass measurements, excluding malnutrition diagnosis

Correct answer: Fluid retention overestimates body weight, potentially masking weight loss from malnutrition

In patients with significant edema or ascites, body weight is overestimated because fluid accumulation masks actual lean tissue loss.

Question 108: What is required to code cardiogenic shock in ICD-10-CM?

Initiation of vasopressor therapy
Explicit physician documentation of cardiogenic shock (Correct answer)
Blood pressure below 90/60 mmHg documented in nursing notes
Cardiac output below 2.2 L/min/m² on Swan-Ganz catheter

Correct answer: Explicit physician documentation of cardiogenic shock

Cardiogenic shock must be explicitly documented by the physician; clinical indicators such as hypotension or vasopressor use cannot be used by coders to assign this diagnosis independently.

Question 109: Which of the following BEST describes the 'present on admission' (POA) query scenario?

A query to determine whether a condition requires treatment during the current hospitalization
A query to confirm the patient's preadmission medication list
A query to establish the principal diagnosis for the current admission
A query asking whether a secondary diagnosis existed before or at the time of inpatient admission (Correct answer)

Correct answer: A query asking whether a secondary diagnosis existed before or at the time of inpatient admission

POA queries ask the physician to clarify whether a condition was present at the time of inpatient admission or developed during the hospitalization.

Question 110: Which type of AKI etiology is most commonly associated with contrast-induced nephropathy?

Pre-renal AKI due to volume depletion
Post-renal AKI from urinary obstruction
Functional AKI from low cardiac output
Intrinsic (intrarenal) AKI from tubular injury (Correct answer)

Correct answer: Intrinsic (intrarenal) AKI from tubular injury

Contrast-induced nephropathy causes direct tubular cell injury, classifying it as intrinsic (intrarenal) AKI rather than pre-renal or post-renal.

Question 111: Which documentation element is MOST critical for supporting a septic shock diagnosis for quality and reimbursement purposes?

Insertion of a central venous catheter
Blood culture results positive for a pathogen
Administration of broad-spectrum antibiotics within 1 hour
Explicit physician attestation of septic shock in the final diagnosis (Correct answer)

Correct answer: Explicit physician attestation of septic shock in the final diagnosis

For coding purposes, explicit physician documentation of 'septic shock' in the final diagnosis—not just treatment indicators—is required to assign the diagnosis.

Question 112: A hospital uses APR-DRG Risk of Mortality (ROM) subclasses primarily for which of the following purposes?

Setting nurse-to-patient staffing ratios mandated by state law
Determining whether to admit a patient to the ICU
Benchmarking observed versus expected mortality rates for quality reporting and risk adjustment (Correct answer)
Calculating the hospital's Medicare case-mix index

Correct answer: Benchmarking observed versus expected mortality rates for quality reporting and risk adjustment

The ROM subclass predicts the likelihood that a patient will die during the hospitalization. Hospitals use it to risk-adjust mortality statistics — comparing observed deaths to the number expected given the patient population's ROM distribution — which is central to quality benchmarking and public reporting.

Question 113: Under ICD-10-PCS, which of the seven characters defines the specific approach used for a procedure?

Character 5 (Approach) (Correct answer)
Character 4 (Body Part)
Character 3 (Root Operation)
Character 6 (Device)

Correct answer: Character 5 (Approach)

In ICD-10-PCS, Character 5 specifies the approach used to reach the operative site, such as open, percutaneous, endoscopic, or via natural or artificial opening.

Question 114: A hospital's CDI program tracks 'documentation integrity rate,' defined as the percentage of medical records that accurately reflect the patient's clinical condition without requiring post-discharge amendments. A low rate indicates:

Concurrent CDI review is failing to catch documentation gaps before discharge (Correct answer)
CDI staff are reviewing too many charts concurrently
The hospital has an unusually high patient acuity that exceeds CDI capacity
Physicians are responding to queries too quickly without clinical review

Correct answer: Concurrent CDI review is failing to catch documentation gaps before discharge

A low documentation integrity rate means records frequently need post-discharge amendments, indicating that the concurrent CDI review process is not catching documentation gaps before the patient is discharged.

Question 115: Which type of encephalopathy is most directly associated with systemic infection causing brain dysfunction in the absence of a central nervous system infection?

Septic encephalopathy (Correct answer)
Anoxic encephalopathy
Hepatic encephalopathy
Hypertensive encephalopathy

Correct answer: Septic encephalopathy

Septic encephalopathy (also called sepsis-associated encephalopathy) is brain dysfunction caused by the systemic inflammatory response to infection — without direct infection of the CNS. It is distinct from meningitis or encephalitis and is a clinically significant and documentable condition.

Question 116: A patient with type 2 diabetes mellitus is documented with CKD Stage 3b. What is the correct ICD-10-CM coding approach?

Assign only N18.32 since CKD is the complicating condition
Assign E11.9 and N18.32 as unrelated diagnoses
Assign E11.22 for diabetic chronic kidney disease plus N18.32 for the specific CKD stage (Correct answer)
Assign only E11.9 since diabetes is the underlying cause

Correct answer: Assign E11.22 for diabetic chronic kidney disease plus N18.32 for the specific CKD stage

ICD-10-CM requires E11.22 (type 2 DM with diabetic CKD) paired with N18.32 (CKD Stage 3b) to capture both the diabetic etiology and the specific stage of CKD.

Question 117: A patient is admitted for sepsis. If the source of the infection is known (e.g., pneumonia), how should the diagnoses be sequenced?

It does not matter which code is sequenced first.
Sequence the code for sepsis first, followed by the code for the localized infection. (Correct answer)
Sequence the localized infection first, followed by the code for sepsis.
Only the code for sepsis should be reported.

Correct answer: Sequence the code for sepsis first, followed by the code for the localized infection.

Per official coding guidelines, if the reason for admission is sepsis and a localized infection, the systemic infection (sepsis) should be sequenced first. The localized infection (e.g., pneumonia) is sequenced as a secondary diagnosis.

Question 118: Under the HAC Reduction Program, hospitals in the worst-performing quartile for HAC rates receive what penalty?

1% reduction in total Medicare payments (Correct answer)
2% reduction in total Medicare payments
25% reduction in DRG payment for each HAC
5% reduction in total Medicare payments

Correct answer: 1% reduction in total Medicare payments

The ACA established a 1% reduction in total Medicare payments for hospitals in the worst-performing quartile under the HAC Reduction Program.

Question 119: A patient presents to the ED with left knee pain and is admitted. During the admission workup, an MRI reveals an occult fracture of the left femoral neck that was not previously diagnosed. What POA indicator applies?

W – clinically undetermined
Y – condition existed before admission (Correct answer)
N – condition arose after admission
U – unknown

Correct answer: Y – condition existed before admission

A condition that existed prior to admission, even if undiagnosed, is still considered present on admission and receives a POA indicator of 'Y'.

Question 120: Which scenario represents an APPROPRIATE use of a retrospective query?

Querying a physician to change a diagnosis that a coder personally disagrees with
Querying after discharge when clinical indicators in the record suggest a condition that was never explicitly documented (Correct answer)
Querying after discharge solely to upgrade the DRG to improve hospital reimbursement
Querying to add a secondary diagnosis already captured and coded during the concurrent review

Correct answer: Querying after discharge when clinical indicators in the record suggest a condition that was never explicitly documented

Retrospective queries are appropriate when the medical record contains clinical evidence of an undocumented condition affecting coding accuracy.

Question 121: What is a critical requirement for documenting a verbal query?

The CDS should simply remember the conversation and inform the coder of the physician's answer.
The CDS must document the question, clinical indicators, and the physician's response in the health record for the physician to sign. (Correct answer)
The CDS must send a follow-up email to the physician summarizing the conversation.
The CDS must record the conversation on a mobile device for future reference.

Correct answer: The CDS must document the question, clinical indicators, and the physician's response in the health record for the physician to sign.

For a verbal interaction to be considered a compliant query, it must be documented in the permanent health record. This documentation should include the question asked, the clinical indicators discussed, the physician's response, and the date/time, followed by the physician's signature or attestation.

Question 122: According to AHIMA/ACDIS query practice guidelines, which of the following query formats is MOST compliant?

A yes/no query asking 'Does this patient have sepsis?'
A verbal query with no documentation in the medical record
A multiple-choice query offering clinically appropriate diagnoses plus 'other' and 'clinically undetermined' (Correct answer)
A query that states 'Please document sepsis to support the ICD-10 code'

Correct answer: A multiple-choice query offering clinically appropriate diagnoses plus 'other' and 'clinically undetermined'

AHIMA/ACDIS guidelines require non-leading queries that offer balanced clinical options. Multiple-choice formats listing plausible diagnoses plus 'other' and 'clinically undetermined' meet this standard.

Question 123: Which clinical indicator would most support a CDI query for acute kidney injury in a hospitalized patient?

Blood urea nitrogen of 15 mg/dL
Serum creatinine rise of 0.4 mg/dL above baseline within 36 hours (Correct answer)
Serum creatinine of 0.9 mg/dL with a baseline of 0.8 mg/dL
Urine output of 600 mL over 8 hours in a 70 kg patient

Correct answer: Serum creatinine rise of 0.4 mg/dL above baseline within 36 hours

A creatinine increase of 0.4 mg/dL above baseline within 36 hours exceeds the KDIGO Stage 1 threshold of ≥0.3 mg/dL within 48 hours, supporting an AKI query.

Question 124: What is the primary purpose of clinical coding?

To translate clinical documentation into standardized codes for billing and data analysis (Correct answer)
To manage patient appointments
To perform clinical research
To document patient care

Correct answer: To translate clinical documentation into standardized codes for billing and data analysis

The primary purpose of clinical coding is to translate the detailed information contained in clinical documentation into standardized alphanumeric codes. These codes are essential for various healthcare functions, including billing and reimbursement, public health reporting, and data analysis for research and quality improvement. Standardization ensures consistency and facilitates efficient communication across the healthcare system.

Question 125: According to ICD-10-CM guidelines, how should 'probable' diagnoses be coded in the outpatient/physician office setting?

Code only the signs and symptoms, not the probable diagnosis (Correct answer)
Code the probable diagnosis with a 'suspected' qualifier code
Code the probable diagnosis as confirmed
Assign an unspecified code from the appropriate chapter

Correct answer: Code only the signs and symptoms, not the probable diagnosis

In outpatient settings, uncertain diagnoses (probable, suspected, rule-out) are coded to the highest degree of certainty — typically signs and symptoms.

Question 126: A CDIS reviews a record where the physician documents 'MRSA bacteremia.' Which ICD-10-CM coding approach is correct?

Code B95.62 as an additional code to A41.02 (Correct answer)
Code only A49.02 for MRSA infection
Code A41.02 for MRSA sepsis instead
Code only the bacteremia without specifying MRSA

Correct answer: Code B95.62 as an additional code to A41.02

A41.02 captures MRSA septicemia/bacteremia; however, B95.62 is assigned as an additional code when MRSA is the causative agent in a condition classified elsewhere.

Question 127: A hospital's compliance audit finds that nearly all CDI queries result in documentation changes that increase DRG weight. What concern does this raise?

The hospital's payer mix likely skews toward more complex patients
The coding staff needs additional training on DRG assignment
The query process may be leading or financially motivated, warranting a compliance review (Correct answer)
The CDI program is performing at peak efficiency

Correct answer: The query process may be leading or financially motivated, warranting a compliance review

If nearly all queries result in DRG-increasing documentation changes, it may indicate that queries are being formulated in a leading manner or are clinically unjustified.

Question 128: Which of the following ICD-10-PCS sections is used to code procedures on peripheral veins?

Section 5 - Extracorporeal or Systemic Assistance
Section 3 - Administration
Section 0 - Medical and Surgical (Correct answer)
Section 2 - Placement

Correct answer: Section 0 - Medical and Surgical

The Medical and Surgical section (Section 0) of ICD-10-PCS covers all surgical procedures on anatomical body parts including peripheral veins.

Question 129: When is it appropriate for a coder to assign the POA indicator 'U' (Unknown)?

When the physician explicitly writes 'POA unknown' in the chart.
When a condition develops 24 hours after admission.
When the documentation is insufficient to make a determination. (Correct answer)
When the physician documents 'possible' for a diagnosis.

Correct answer: When the documentation is insufficient to make a determination.

The 'U' indicator should be used as a last resort when the medical record documentation is insufficient to determine if the condition was present at the time of admission. This indicates a documentation gap that could not be clarified.

Question 130: A physician documents 'possible aspiration pneumonia' in the H&P but does not confirm or deny it was present on admission. What POA indicator should be assigned?

Y
N
W
U (Correct answer)

Correct answer: U

When documentation is insufficient to determine whether a condition was present on admission, the POA indicator 'U' (unknown) is assigned.

Question 131: A hospital notices its observed mortality rate is significantly higher than the expected rate for pneumonia patients. The CDI manager suspects documentation deficiency. What is the MOST likely documentation gap?

Pneumonia type is not specified
The hospital is admitting more patients from long-term care facilities
Secondary diagnoses that capture patient complexity are not being documented (Correct answer)
Attending physicians are not signing discharge summaries within required timeframes

Correct answer: Secondary diagnoses that capture patient complexity are not being documented

When observed mortality exceeds expected mortality, it often indicates that secondary diagnoses reflecting patient complexity such as MCCs are not being documented. Without these diagnoses, the risk-adjustment model underestimates expected mortality.

Question 132: Which statement BEST describes the relationship between Severity of Illness (SOI) and Risk of Mortality (ROM) scores in the APR-DRG system?

SOI and ROM scores are averaged to produce a single quality indicator
SOI and ROM are calculated identically and always produce the same score
ROM is used only for surgical DRGs while SOI applies to medical DRGs
SOI measures resource use while ROM independently measures likelihood of death (Correct answer)

Correct answer: SOI measures resource use while ROM independently measures likelihood of death

In the APR-DRG system, SOI and ROM are separate, independently calculated measures. SOI reflects the extent of physiologic decompensation and resource intensity, while ROM reflects the likelihood that the patient will die.

Question 133: What is the primary objective of healthcare documentation?

To reduce the time spent on patient care
To ensure accurate, complete, and timely documentation of patient care (Correct answer)
To increase hospital revenue
To manage hospital staff assignments

Correct answer: To ensure accurate, complete, and timely documentation of patient care

The primary objective of healthcare documentation is to ensure accurate, complete, and timely recording of all aspects of patient care. This includes the patient's medical history, diagnoses, treatments, medications, and responses to care. Comprehensive documentation is crucial for patient safety, continuity of care, legal protection, and accurate billing and reimbursement.

Question 134: The Cooperating Parties for ICD-10-CM/PCS include all of the following EXCEPT:

American Medical Association (AMA) (Correct answer)
American Health Information Management Association (AHIMA)
National Center for Health Statistics (NCHS)
American Hospital Association (AHA)

Correct answer: American Medical Association (AMA)

The four Cooperating Parties are AHIMA, AHA, NCHS, and CMS; the AMA maintains CPT, not ICD-10-CM/PCS.

Question 135: What CDI query approach is most appropriate for new-onset arrhythmia occurring after cardiac surgery?

Assume it is a complication and assign the complication code automatically
Disregard it since postoperative arrhythmia is universally expected after cardiac surgery
Query to distinguish postoperative complication arrhythmia from preexisting or coincidental arrhythmia (Correct answer)
Code the arrhythmia without querying since the timing is documented

Correct answer: Query to distinguish postoperative complication arrhythmia from preexisting or coincidental arrhythmia

Clarifying whether the arrhythmia is a postoperative complication or a preexisting/coincidental condition affects diagnosis coding, complication rates, and quality metrics.

Question 136: A CDI specialist sends a query for hypertensive heart disease. The physician responds 'clinically undetermined.' What is the correct action?

Code hypertensive heart disease anyway based on clinical indicators in the record
Escalate to the chief medical officer to override the physician's response
Re-query the physician with more specific clinical indicators
Accept the response and code without hypertensive heart disease (Correct answer)

Correct answer: Accept the response and code without hypertensive heart disease

When a physician responds 'clinically undetermined,' the CDI specialist must accept the response and code the case without the queried diagnosis. Physician responses including negative responses must be honored.

Question 137: When a physician responds to a query by selecting 'other — specify' and writes in a diagnosis, the CDI specialist should NEXT:

Verify the written-in diagnosis is supported by the clinical documentation before coding it (Correct answer)
Escalate to the compliance department because write-in responses are inherently non-compliant
Code the written-in diagnosis immediately because the physician's response is always definitive
Return a second query asking the physician to choose one of the pre-listed options instead

Correct answer: Verify the written-in diagnosis is supported by the clinical documentation before coding it

CDI specialists must confirm that any physician-specified diagnosis is clinically supported in the record before it is used for coding.

Question 138: A patient is admitted with chest pain. After a full workup, myocardial infarction is ruled out, and the physician determines the cause of the chest pain to be gastroesophageal reflux disease (GERD). According to UHDDS guidelines, what is the principal diagnosis?

Chest pain
Acute myocardial infarction
Unspecified cardiac condition
Gastroesophageal reflux disease (GERD) (Correct answer)

Correct answer: Gastroesophageal reflux disease (GERD)

The principal diagnosis is defined as the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care. In this case, GERD was the final diagnosis determined to be the cause of the admission.

Question 139: Under the Hospital-Acquired Condition Reduction Program (HACRP), what happens to hospitals in the worst-performing quartile?

They must submit corrective action plans without financial penalty
They receive enhanced reimbursement to fund quality improvement
They receive a 1% reduction in Medicare inpatient payments (Correct answer)
They are excluded from the Medicare program

Correct answer: They receive a 1% reduction in Medicare inpatient payments

Under HACRP, hospitals in the lowest-performing quartile for hospital-acquired conditions receive a 1% reduction in all Medicare inpatient payments.

Question 140: Which Present on Admission (POA) indicator is assigned when documentation is insufficient to determine if a condition was present at the time of inpatient admission?

Y
U (Correct answer)
N
W

Correct answer: U

POA indicator 'U' is assigned when documentation is insufficient to determine if the condition was present on admission.
