CRC Clinical Documentation Improvement 2 — Questions and Answers
Question 1: A CDI specialist reviews a chart where the physician documents 'CHF' without further specification. Which query would be most effective for risk adjustment?
- Is the heart failure systolic, diastolic, or combined?
- Does the patient have acute or chronic heart failure?
- What is the heart failure type, acuity, and current severity class? (Correct answer)
- Should we code I50.9 for unspecified heart failure?
Correct answer: What is the heart failure type, acuity, and current severity class?
An effective CDI query should address all specificity elements: type, acuity, and severity. This avoids multiple follow-ups.
Heart failure coding for risk adjustment requires maximum specificity. A comprehensive query generates documentation that fully supports the assigned code and is defensible during RADV audits.
Question 2: A CDI specialist notices lab values showing eGFR of 22 mL/min but the physician only documents 'renal insufficiency.' What is the appropriate CDI action?
- Code N18.4 for CKD stage 4 based on lab values alone
- Query the provider to document CKD stage consistent with the eGFR findings (Correct answer)
- Document the CKD stage in a CDI note for the coder
- Wait for the discharge summary for additional specificity
Correct answer: Query the provider to document CKD stage consistent with the eGFR findings
CDI specialists cannot diagnose based on lab values alone. The appropriate action is to query the provider to document the CKD stage.
An eGFR of 22 mL/min suggests CKD stage 4, which maps to HCC 137 with significant RAF weight. Coding guidelines prohibit inferring diagnoses from lab values without provider documentation.
Question 3: A physician documents 'patient is malnourished.' The dietitian's assessment documents 'severe protein-calorie malnutrition with BMI 15.2.' For CDI purposes, which source can be used?
- Only the physician's documentation
- The dietitian's assessment directly
- A CDI query should be generated for the physician to confirm the severity (Correct answer)
- Both sources are equally valid
Correct answer: A CDI query should be generated for the physician to confirm the severity
Best practice for risk adjustment is to have the physician document or confirm the severity, creating the strongest documentation for RADV audit defense.
For risk adjustment where diagnoses must withstand RADV audit scrutiny, physician confirmation is the gold standard. The CDI specialist should query the physician referencing the dietitian's assessment.
Question 4: A CDI team finds query response rate dropped from 85% to 60%. Which strategy is most likely to improve physician engagement?
- Implement mandatory query response requirements with consequences
- Redesign queries to be more specific with clinical indicators and response checkboxes (Correct answer)
- Reduce queries to only target high-value HCC conditions
- Switch from concurrent to retrospective queries
Correct answer: Redesign queries to be more specific with clinical indicators and response checkboxes
Improving query design with specific clinical indicators and easy response formats is the most effective strategy.
Well-designed queries referencing specific clinical indicators, providing response options as checkboxes, and keeping queries concise consistently achieve the highest response rates.
Question 5: Which documentation improvement scenario would have the greatest positive impact on risk adjustment accuracy?
- Changing 'diabetes' to 'diabetes mellitus type 2 with diabetic nephropathy' when supported by evidence (Correct answer)
- Adding BMI values to every encounter for patients with obesity
- Documenting medication lists in detail for every visit
- Recording vital signs with greater precision
Correct answer: Changing 'diabetes' to 'diabetes mellitus type 2 with diabetic nephropathy' when supported by evidence
Specifying diabetes type and capturing complications directly affects HCC mapping. Diabetes with nephropathy maps to HCC 18, nearly tripling the RAF contribution vs diabetes alone.
E11.9 maps to HCC 19 (RAF ~0.105) while E11.22 maps to HCC 18 (RAF ~0.302). This single documentation improvement nearly triples the condition's RAF contribution.
Question 6: A CDI specialist finds a patient admitted for pneumonia also has chronic respiratory failure with home oxygen documented on the problem list but not addressed in the current encounter. What action is appropriate?
- No action needed since it is on the problem list
- Query the provider to address the chronic respiratory failure in the current encounter (Correct answer)
- Add a CDI note referencing the problem list
- Remove the condition from consideration
Correct answer: Query the provider to address the chronic respiratory failure in the current encounter
For risk adjustment, conditions must be documented as actively addressed in the current encounter, not just present on a problem list.
Problem list entries alone are generally insufficient for risk adjustment coding. CMS requires conditions to be documented in the encounter note as being evaluated, assessed, treated, or monitored.
