Market structure

Concentration is not shown for markets under 11 billing groups.

Of volume attributable to named groups, independents account for 0%; hospital-affiliated 100%.

Disclosed setting mix: 100% office · 0% facility.

HHI trend: (group rosters begin 2019)

Provider-setting count 2016 → 2024: 5 → 4 (-20%).

Named groups cover 100% of disclosed volume. CMS suppresses provider-code rows under 11 beneficiaries at the source; suppressed volume is excluded and cannot be estimated from this file. Volume shares describe the volume attributable to named groups; the coverage line above states how much of disclosed Medicare fee-for-service volume that is.

*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 →
