The full analytics for this group
PremiumThe billed-volume rank, trajectory, and economics behind this group — computed on the same disclosed Medicare Part B data.
- Per-code payment breakdown & avg $/service — dollars behind the volume
- Beneficiary-episode volume — reach, not just service counts
- Office vs. facility setting mix — place-of-service code split
- National billed-volume rank — percentile, cohort & year disclosed
- Size-peer billed-volume benchmark — vs. groups of similar size
- Top-3 clinician share — how volume distributes
- 5-year volume trend — direction across the window
- Business mix — largest codes by payment
Rank and benchmark figures are billed-volume positions among peers, not measures of care. All figures attributed (single-group clinicians) and disclosed Medicare Part B fee-for-service.

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.
