99232 vs 99233: Time vs MDM for Hospitalist Subsequent Visits
Choose the supported subsequent hospital or observation service. Patient acuity and the work performed matter; a target code distribution does not.
Use two of three MDM elements
99232 requires moderate MDM; 99233 requires high MDM. Risk alone is insufficient. Document problems addressed, data, and management risk.
When selecting by time
The minimum total times are 25 minutes for 99231, 35 for 99232 and 50 for 99233. Exclude separately reported work.
Keep payer rules distinct
Medicare G0316 with time-selected 99233 starts at 65 qualifying minutes. Payers recognizing CPT prolonged services may use 99418. Deleted 99356/99357 codes are not current alternatives.
