Documented Medicare service activity
Reporting year: 2024. These are billed services or units in Original Medicare Part B, not total career experience, all patients, surgical case counts or a quality rating.
Scroll the table sideways to see every column.
| HCPCS | Billed services / units | Beneficiaries in this row | Service description (English) | Billing setting |
|---|---|---|---|---|
| 99223 | 60 | 58 | Initial hospital care with moderate level of medical decision making, if using time, at least 75 minutes | Facility |
| 99291 | 15 | 15 | Critical care, first 30-74 minutes | Facility |
How to interpret these counts
CMS suppresses provider/service rows involving fewer than 11 beneficiaries. Services may repeat for one person, and beneficiaries cannot be added across rows. Facility/non-facility describes billing and does not establish a current hospital affiliation. These counts do not report case complexity, clinical outcomes or whether a treatment is appropriate for you.
