Medicare volume is ranked against active providers in the same specialty.

What this provider does (Medicare)

Typical Medicare-allowed amounts for these services range $4–$168 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, 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.
