CCDS Cardiac Conditions and Documentation 4 — Questions and Answers
Question 1: A patient is admitted with chest pain and troponin elevation. The cardiologist documents 'demand ischemia due to sepsis.' How should the CDI specialist query this?
- Query for acute MI type 2 due to supply-demand mismatch (Correct answer)
- Query for NSTEMI as the principal diagnosis
- Accept demand ischemia as a valid ICD-10 code without querying
- Query for unstable angina instead
Correct answer: Query for acute MI type 2 due to supply-demand mismatch
Demand ischemia due to an underlying condition like sepsis classifies as Type 2 MI, which has its own ICD-10-CM code and impacts severity of illness.
Question 2: Which documentation element is most critical when a physician records 'cardiomegaly' on imaging but the clinical note mentions 'dilated cardiomyopathy'?
- Query to clarify whether cardiomegaly is a separate finding or the result of dilated cardiomyopathy (Correct answer)
- Code both diagnoses separately as they are distinct conditions
- Code only cardiomegaly as it is the radiological finding
- Ignore cardiomegaly and code only dilated cardiomyopathy
Correct answer: Query to clarify whether cardiomegaly is a separate finding or the result of dilated cardiomyopathy
CDI specialists must query when imaging findings and clinical diagnoses conflict or overlap to ensure accurate and complete coding.
Question 3: A patient with chronic systolic heart failure is admitted. The physician documents 'acute on chronic systolic heart failure' on day 2 but not in the discharge summary. What should the CDI specialist do?
- Issue a query asking the physician to clarify and confirm the acute exacerbation in the discharge summary (Correct answer)
- Code the acute on chronic heart failure based on the day 2 note alone
- Code only chronic systolic heart failure as documented in the discharge summary
- Escalate to coding supervisor without querying
Correct answer: Issue a query asking the physician to clarify and confirm the acute exacerbation in the discharge summary
All treating physician documentation can be used for coding, but a query ensures consistency and physician attestation in the final record.
Question 4: When coding atrial fibrillation with rapid ventricular response (RVR), which statement is most accurate?
- Atrial fibrillation with RVR is coded as atrial fibrillation; RVR is an integral manifestation and not coded separately (Correct answer)
- RVR is coded as a separate tachyarrhythmia in addition to atrial fibrillation
- RVR requires a separate query to confirm ventricular tachycardia
- Atrial fibrillation with RVR defaults to unspecified atrial fibrillation
Correct answer: Atrial fibrillation with RVR is coded as atrial fibrillation; RVR is an integral manifestation and not coded separately
Rapid ventricular response is a manifestation of uncontrolled atrial fibrillation and is not assigned a separate code.
Question 5: 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 6: Which of the following best describes the CDI impact of documenting 'acute systolic heart failure' versus 'acute heart failure, unspecified'?
- Systolic specification increases diagnosis-related group (DRG) weight and reflects higher severity of illness (Correct answer)
- Both terms map to the same ICD-10-CM code and DRG
- Unspecified heart failure captures higher complexity than systolic heart failure
- Systolic heart failure only applies to EF below 40% and does not affect DRG
Correct answer: Systolic specification increases diagnosis-related group (DRG) weight and reflects higher severity of illness
Specifying systolic versus diastolic heart failure maps to distinct ICD-10-CM codes that affect DRG assignment and quality metrics.
Question 7: A patient is admitted post-cardiac arrest with ROSC (return of spontaneous circulation). The physician documents 'anoxic brain injury' and 'acute respiratory failure.' What is the CDI specialist's priority query?
- Query to clarify the principal diagnosis and whether cardiac arrest or anoxic brain injury drives the admission (Correct answer)
- Accept cardiac arrest as principal and code anoxic brain injury as secondary
- Query to confirm the cardiac arrest cause before assigning any codes
- Code acute respiratory failure as principal since it requires the most resources
Correct answer: Query to clarify the principal diagnosis and whether cardiac arrest or anoxic brain injury drives the admission
Determining the principal diagnosis among post-arrest complications requires physician clarification to ensure the condition that drove the admission is correctly identified.
