A CCDS notes a patient on mechanical ventilation for 36 hours. Which CDI action is most appropriate regarding duration-based code assignment?
- A. No query needed; 36 hours falls in the less-than-96-hour category

- C. Assign the greater-than-96-hours code prospectively
- D. Duration has no impact on mechanical ventilation coding
Answer: B. Query the physician to confirm total hours to determine if the 96-hour threshold will be met
Since 36 hours is approaching the 96-hour threshold (5Z09.3 vs. 5Z09.4 under PCS), the CCDS should monitor and query if the total duration crosses 96 hours.

Under MS-DRGs, a CC (complication/comorbidity) and an MCC (major complication/comorbidity) are secondary diagnoses that indicate added severity. Many MS-DRGs are split into "with MCC," "with CC," and "without CC/MCC," so documenting one well-supported MCC can move a case into a higher-weighted DRG.

Under the ACDIS/AHIMA Guidelines for Achieving a Compliant Query Practice, a query must not lead the provider toward a specific diagnosis or mention its financial impact.
