When coding sequela, report the residual condition first, then the cause using the appropriate injury code with the 7th character 'S'.
Question 83: What is the purpose of an Explanation of Benefits (EOB) sent to the patient?
- It certifies the patient's eligibility for coverage
- It authorizes the provider to perform a specific service
- It explains how the insurance company processed the claim and what, if anything, the patient owes (Correct answer)
- It is a bill requesting payment from the patient
Correct answer: It explains how the insurance company processed the claim and what, if anything, the patient owes
An EOB details how a claim was processed, including amounts billed, allowed, paid by insurance, and the patient's responsibility—but it is not a bill.
Question 84: What symbol in ICD-10-CM indicates that another code is needed to fully describe the condition?
- Use additional code (Correct answer)
- +
- •
- †
Correct answer: Use additional code
In ICD-10-CM, the 'Use additional code' note indicates that the code selected may not fully describe the patient's condition and that another code is required to provide a complete picture. This convention ensures comprehensive and accurate reporting of diagnoses. It's a crucial instruction for coders to follow to avoid incomplete coding.
Question 85: Which element is NOT one of the seven components recommended in the OIG's Compliance Program Guidance for hospitals?
- Effective training and education
- Written policies and procedures
- Designated compliance officer
- Annual patient satisfaction surveys (Correct answer)
Correct answer: Annual patient satisfaction surveys
Patient satisfaction surveys are not among the OIG's seven recommended compliance program elements; the seven focus on internal controls, training, auditing, and reporting.
Question 86: Which coding convention is used to indicate a condition that should not be coded together with another?
- Includes
- Excludes2
- Excludes1 (Correct answer)
- See also
Correct answer: Excludes1
The 'Excludes1' convention in ICD-10-CM indicates that the code excluded should never be used with the code above the 'Excludes1' note. This means the two conditions are mutually exclusive and cannot occur together. It's a strict instruction to prevent incorrect coding of separate, distinct conditions.
Question 87: Which technology trend is most likely to impact quality assurance & performance improvement in the CMC field in coming years?
- Complete elimination of human professionals
- Reduction in the need for professional certification

Digital tools for enhanced data collection, analysis, and reporting represent the most significant and practical technology trend impacting quality assurance & performance improvement, augmenting rather than replacing professional expertise.
Question 88: What is the correct approach when a CPT code description includes the phrase 'each additional' or 'list separately'?
- Report it only as an add-on code alongside the primary procedure code (Correct answer)
- Report it with modifier -51
- Report it only once regardless of quantity
- Report the code as a stand-alone code
Correct answer: Report it only as an add-on code alongside the primary procedure code
Phrases like 'each additional' or 'list separately' identify add-on codes that must always be reported with a specified primary procedure code, never independently.
Question 89: A coder is asked by a physician to add a diagnosis code not documented in the medical record to justify a procedure. The coder should:
- Add the code since the physician has clinical authority
- Query the physician and add the code once they verbally confirm
- Add the code only if it seems clinically plausible
- Refuse and document the request, reporting it through compliance channels (Correct answer)
Correct answer: Refuse and document the request, reporting it through compliance channels
Coders must only assign codes supported by documentation; adding undocumented codes constitutes fraud, and the request should be refused and reported through compliance channels.
Question 90: What does the term 'code also' mean in coding guidelines?
- Sequencing doesn’t matter
- Another code may be required (Correct answer)
- Use one code only
- Optional coding
Correct answer: Another code may be required
The 'code also' note in coding guidelines indicates that two codes may be required to fully describe a condition, but the sequencing of these codes is not specified. It suggests that the condition represented by the 'code also' note may be a manifestation of the primary condition or a co-existing condition. Coders must use clinical judgment to determine if the additional code is appropriate.
Question 91: CPT code 99213 is a typical example of which type of service?
- Office or other outpatient established patient visit (Correct answer)
- Emergency department visit
- Inpatient hospital visit
- Preventive medicine visit
Correct answer: Office or other outpatient established patient visit
CPT 99213 represents an office or other outpatient visit for an established patient requiring a medically appropriate history, exam, and medical decision-making of low complexity.
Question 92: When coding an encounter for a condition that is both acute and chronic, which form should generally be sequenced first?
- Chronic form
- Alphabetical order determines sequencing
- Acute form (Correct answer)
- Either form, based on coder preference
Correct answer: Acute form
ICD-10-CM guidelines direct coders to sequence the acute condition first when separate codes exist for both acute and chronic forms.
Question 93: Which CMS program uses Risk Adjustment Data Validation (RADV) audits to ensure coding accuracy?
- Medicaid managed care for pediatric patients
- Medicare Advantage (Part C) (Correct answer)
- Traditional fee-for-service Medicare Part B
- Medicare Part D prescription drug plans
Correct answer: Medicare Advantage (Part C)
CMS conducts RADV audits for Medicare Advantage plans to verify that submitted diagnosis codes are supported by medical record documentation and accurate risk scores.
Question 94: What does HIPAA primarily regulate?
- Insurance reimbursement rates
- Medical billing fees
- Patient health information privacy (Correct answer)
- Healthcare provider licensing
Correct answer: Patient health information privacy
HIPAA, the Health Insurance Portability and Accountability Act, primarily regulates the privacy and security of patient health information (PHI). It established national standards for the protection of sensitive patient data, ensuring that individuals' medical records are kept confidential and secure. This law impacts how healthcare providers, health plans, and clearinghouses handle patient information.
Question 95: What ethical consideration is most relevant to professional ethics & legal compliance in CMC practice?
- Avoiding all professional development activities
- Following only those rules that are convenient
- Maintaining confidentiality and acting in the best interest of stakeholders (Correct answer)
- Prioritizing personal advancement over professional duties
Correct answer: Maintaining confidentiality and acting in the best interest of stakeholders
Maintaining confidentiality and acting in the best interest of stakeholders is the cornerstone ethical consideration for professional ethics & legal compliance in professional practice.
Question 96: When the ICD-10-CM guidelines state 'and' in a code title, it means:
- Both conditions must be present to use the code
- 'And' should be interpreted as 'and/or' (Correct answer)
- The condition is bilateral
- The code requires two diagnosis fields
Correct answer: 'And' should be interpreted as 'and/or'
Per ICD-10-CM convention, the word 'and' in code titles means 'and/or,' so the code applies if either or both conditions are documented.
Question 97: The term 'osteoporosis' literally translates to:
- Porous bone condition (Correct answer)
- Bone inflammation
- Bone softening
- Bone tumor
Correct answer: Porous bone condition
Osteo- means bone, por- means porous, and -osis means condition, so osteoporosis is literally a porous bone condition.
Question 98: Which of the following best describes a key competency required for evidence-based practice & research methods in CMC certification?
- Delegation of all complex tasks to supervisors
- Critical thinking and evidence-based decision making (Correct answer)
- Ability to work independently without any oversight
- Memorization of all relevant regulations verbatim
Correct answer: Critical thinking and evidence-based decision making
Critical thinking and evidence-based decision making is essential for evidence-based practice & research methods, as professionals must analyze situations and apply knowledge appropriately.
Question 99: Which section of the ICD-10-CM manual is used to locate diagnosis codes alphabetically?
- Table of Drugs and Chemicals
- Tabular List
- Neoplasm Table
- Alphabetic Index (Correct answer)
Correct answer: Alphabetic Index
The Alphabetic Index is consulted first to locate potential codes, which are then verified in the Tabular List before final code assignment.
Question 100: In CPT, what is a 'separate procedure' designation?
- A procedure always billed independently
- A procedure coded only on outpatient claims
- A procedure integral to a larger service and not separately reported when performed as part of that service (Correct answer)
- A procedure requiring a modifier
Correct answer: A procedure integral to a larger service and not separately reported when performed as part of that service
Procedures labeled 'separate procedure' in CPT are commonly bundled into larger services and should not be reported separately unless performed independently.
