Reading these numbers
Historical averages are not current prices
The allowed amount includes Medicare’s share plus applicable beneficiary and third-party responsibility. It is not the amount Medicare alone paid. Linked codes open current geographic fee-schedule comparisons using RVU26D. Find current local rates.
Read counts in context
Facility and non-facility rows stay separate. Beneficiaries are distinct within one code and setting, but cannot be added across rows to count unique people. CMS publishes some fractional service counts; we preserve them.
Source and selection
CMS Medicare Physician & Other Practitioners, by Geography and Service. Calendar year 2024; source published 2026-05-21. Only national rows marked non-drug are included. Rankings do not reconstruct suppressed or unpublished records.
