What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.
| Service (HCPCS) | Medicare services | Typical Medicare-allowed (2024) |
|---|---|---|
| Anesthesia for X-Ray Or Radiation Therapy01922 | 13 | $168 |
| Anesthesia for Procedure to Correct Abnormal Heart Rhythm00410 | 12 | $91 |
Typical Medicare-allowed amounts for these services range $91–$168 (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.
