By clinician headcount, CY2024. 'Physician' follows Medicare's §1861(r) definition (MD/DO, podiatry, optometry, dental medicine, chiropractic); facility and supplier enrollments are not counted as clinicians.

This group's attributed Medicare payments across all codes were premium in CY2024.

Dollars, place-of-service mix, national standing and peer benchmarks are part of the market analytics platform — built, not launched yet. Notify me at launch →

All figures are attributed (single-group clinicians only) and disclosed (CMS suppresses fewer-than-11-beneficiary rows) Medicare Part B fee-for-service — a subset, never complete totals. Percentile and peer figures are billed-volume positions, not statements about care. See Methods & Sources.

Volumes are attributed to a group only for clinicians affiliated with exactly one group. Clinicians in several groups are listed ("member of N groups") but shown as "—" — their volume is not attributed to any single group. A "—" on a single-group clinician means CMS suppressed the figure (fewer than 11 beneficiaries), never zero. Beneficiary-episodes count CMS's per-setting beneficiary figures, not unique patients. Average Medicare payment is the amount Medicare actually paid per service, weighted by service volume across office and facility settings. Where the roster is a single clinician, that clinician's service counts match the group's attributed volume shown on the ranked results, so they are shown here; the per-provider split across a larger roster is a premium feature.
