20 Medicare services, 2024 (ranked within specialty)
Medicare volume is ranked against active providers in the same specialty.

Typical Medicare-allowed amounts for these services range $108–$108 (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.
