CCDS CDI and Quality Metrics 5 — Questions and Answers
Question 1: 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 chronic conditions
- Guideline on combination codes
- Guideline on neoplasm coding and sequencing (Correct answer)
- Guideline on signs and symptoms
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 2: A CDI specialist notices that a hospital's Patient Safety Indicator (PSI) 90 composite score has worsened. Which action would be MOST effective?
- Increasing query volume for all admitted patients
- Reviewing cases that triggered PSI flags to identify documentation gaps or true quality events (Correct answer)
- Appealing all PSI scores with CMS directly
- Focusing exclusively on improving CMI
Correct answer: Reviewing cases that triggered PSI flags to identify documentation gaps or true quality events
Analyzing cases that contributed to PSI 90 allows CDI and quality teams to determine whether scores reflect true adverse events or documentation gaps requiring clarification.
Question 3: What is the relationship between a hospital's Geometric Mean Length of Stay (GMLOS) and CDI quality efforts?
- GMLOS is unrelated to CDI documentation practices
- Accurate CC/MCC capture through CDI can align GMLOS with appropriate DRG benchmarks (Correct answer)
- GMLOS is determined solely by nursing staffing ratios
- A higher GMLOS always indicates better CDI performance
Correct answer: Accurate CC/MCC capture through CDI can align GMLOS with appropriate DRG benchmarks
Capturing Complications and Comorbidities (CC) and Major Complications and Comorbidities (MCC) through CDI queries moves cases to higher-weighted DRGs with longer expected GMLOS, better reflecting the patient's acuity.
Question 4: 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 POA indicators are being assigned accurately for all secondary diagnoses (Correct answer)
- Whether the hospital is billing for all procedures performed
- Whether nursing documentation matches physician notes
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 5: Under the Hospital-Acquired Condition Reduction Program (HACRP), what happens to hospitals in the worst-performing quartile?
- They receive a 1% reduction in Medicare inpatient payments (Correct answer)
- They are excluded from the Medicare program
- They must submit corrective action plans without financial penalty
- They receive enhanced reimbursement to fund quality improvement
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 6: A CDI specialist is asked to help improve the hospital's performance on the Excess Days in Acute Care (EDAC) measure. What documentation focus is MOST relevant?
- Documenting all chronic conditions as principal diagnoses
- Ensuring discharge condition and plan are clearly documented to support appropriate post-acute placement and reduce unnecessary returns (Correct answer)
- Increasing the number of procedures documented
- Focusing on MCC capture to raise CMI
Correct answer: Ensuring discharge condition and plan are clearly documented to support appropriate post-acute placement and reduce unnecessary returns
EDAC measures post-discharge days in acute care settings; clear documentation of discharge condition and follow-up planning supports transitions of care that reduce unnecessary acute readmissions or ED visits.
Question 7: Which data source does CMS primarily use to calculate risk-adjusted quality measures such as mortality and readmissions for hospital comparison?
- Hospital incident reports submitted quarterly
- Medicare fee-for-service claims data (Correct answer)
- Voluntary hospital quality surveys
- State health department records
Correct answer: Medicare fee-for-service claims data
CMS uses Medicare fee-for-service claims data submitted by hospitals to calculate risk-adjusted quality measures including mortality and 30-day readmission rates for public reporting.
