*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. Modeled all-payer databases project the remainder statistically; we publish the audited floor and label it as such. Same market, different denominator. How the numbers reconcile →
