Medicare $ counts 94453 payments in the market each row names, CY2024; avg list is that row's submitted charges per service on the same basis — list amounts, not payments.

*Share of the state's disclosed Medicare-FFS services for the primary code, counted once per clinician. "St" is the state the volume was billed from: a group appears in each state where its clinicians bill Medicare, with that state's volume and share ("City" is the group's registered location). Group figures sum clinicians affiliated with exactly one group; clinicians in several groups are listed in each group's drill-down but not volume-attributed to any single group, so shares reflect attributable volume. See Methods.

Comparing against an all-payer estimate?

These are exact counts from Medicare fee-for-service claims — roughly a third to half of most procedure markets, depending on payer mix — and the observed foundation every market figure here builds on. Market totals anchor on a labeled all-Medicare estimate scaled from that foundation, with the observed count disclosed beside it — Medicare only, never all-payer. Modeled all-payer databases project every payer statistically and typically run higher. Same market, different denominator. How the numbers reconcile →
