CDIP Technology and Health Information Systems 4 — Questions and Answers
Question 1: Which HL7 standard is primarily used for exchanging clinical documents such as discharge summaries and operative notes in an interoperable format?
- HL7 v2.x messaging
- Clinical Document Architecture (CDA) (Correct answer)
- FHIR Observation resource
- HL7 v3 RIM
Correct answer: Clinical Document Architecture (CDA)
HL7 CDA (Clinical Document Architecture) is the standard specifically designed for structuring and exchanging clinical documents like discharge summaries.
Question 2: A CDI specialist notices that a physician's EHR progress note is auto-populated with yesterday's vitals via copy-forward. What is the PRIMARY risk this presents for documentation integrity?
- Increased query response time
- Perpetuation of inaccurate or outdated clinical information (Correct answer)
- Duplicate billing for the same service
- Violation of HIPAA minimum necessary rule
Correct answer: Perpetuation of inaccurate or outdated clinical information
Copy-forward (cloning) carries outdated information into new notes, perpetuating inaccuracies that can misrepresent the patient's current clinical status.
Question 3: In the context of ICD-10-CM/PCS coding, what is the function of a 'grouper' software application?
- It clusters patient diagnoses for population health reporting
- It assigns diagnosis and procedure codes to MS-DRGs for reimbursement (Correct answer)
- It validates code combinations against NCCI edits
- It encrypts coded data before transmission to payers
Correct answer: It assigns diagnosis and procedure codes to MS-DRGs for reimbursement
Grouper software takes assigned ICD-10-CM/PCS codes and maps them to an MS-DRG, which determines the reimbursement level under Medicare's IPPS.
Question 4: A hospital implements a real-time CDI alert within the EHR that fires when a patient's lab value meets sepsis criteria but no sepsis diagnosis is documented. This is an example of which technology?
- Natural language processing (NLP) query generation
- Clinical decision support (CDS) integrated with CDI workflow (Correct answer)
- Computer-assisted coding (CAC) suggestion engine
- Master patient index (MPI) deduplication alert
Correct answer: Clinical decision support (CDS) integrated with CDI workflow
Real-time alerts triggered by clinical data thresholds to prompt documentation review represent clinical decision support integrated into CDI workflows.
Question 5: Which data standard defines the vocabulary for nursing diagnoses and is included in the NLM's Unified Medical Language System (UMLS) Metathesaurus?
- SNOMED CT
- NANDA International (Correct answer)
- RxNorm
- LOINC
Correct answer: NANDA International
NANDA International provides standardized nursing diagnosis terminology and is incorporated into the UMLS Metathesaurus to support interoperability.
Question 6: An Accountable Care Organization (ACO) uses its health information system to stratify patients by predicted utilization. Which underlying model type is MOST commonly used for this risk stratification?
- Decision tree classifier trained on lab values only
- Hierarchical Condition Category (HCC) risk adjustment model (Correct answer)
- MS-DRG grouper logic applied prospectively
- SNOMED CT expression constraint queries
Correct answer: Hierarchical Condition Category (HCC) risk adjustment model
HCC risk adjustment models use diagnosis codes to predict future healthcare costs and are the foundation of CMS risk stratification for ACOs and Medicare Advantage.
Question 7: When a CDI program evaluates its computer-assisted coding (CAC) system, which metric BEST measures the CAC engine's ability to suggest the correct principal diagnosis?
- Precision of all suggested codes across all code types
- First-listed diagnosis acceptance rate by coders (Correct answer)
- Average time to code completion per record
- Number of encoder look-up queries per chart
Correct answer: First-listed diagnosis acceptance rate by coders
The first-listed (principal) diagnosis acceptance rate specifically measures how often coders accept the CAC's top suggestion without modification, reflecting principal diagnosis accuracy.
