*Share of Illinois's disclosed Medicare-FFS services for 90791, counted once per clinician. Volume is placed in the state it was billed from, so this page ranks the groups actually billing 90791 in Illinois — 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. Full method: Methods & Sources.

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 →
