*Share of District of Columbia's disclosed Medicare-FFS services for 93970, counted once per clinician. Volume is placed in the state it was billed from, so this page ranks the groups actually billing 93970 in District of Columbia — including groups registered elsewhere ("City" is each 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.
How to read this. Figures are Medicare fee-for-service only — not all-payer — from the CMS Medicare Physician & Other Practitioners Public Use File (Part B), CY2024 release. CMS suppresses any provider×code row under 11 beneficiaries, so a missing group means "suppressed," never zero. "Charges" are provider-submitted amounts, not payments. Groups are ranked by measured service volume attributed to clinicians in exactly one group — clinicians affiliated with several groups are listed in rosters but never volume-attributed to a single group — a direct read of the public record, not a rating or quality score.

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 →
