What this provider does (Medicare)

|---|---|---|
| Subsequent Hospital Care With Moderate Levelof Medical Decision Making, If Using Time, at Least 35 Minutes99232 | 45 | $71 |
| Hospital Discharge Day Management, More Than 30 Minutes99239 | 16 | $103 |
Typical Medicare-allowed amounts for these services range $71–$103 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, not a price quote and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.
