The full analytics for this provider

Premium

The billed-volume positioning, practice focus, and economics behind this provider — computed on the same disclosed Medicare Part B data.

This provider's disclosed submitted charges across all codes were in CY2024. Included with Platform.

  • Charge, service & beneficiary totals — the disclosed scale, all codes
  • Practice profile — focus & reach — top codes by share of services
  • Office vs. facility setting mix — place-of-service code split
  • Peer positioning — service volume — percentile among specialty peers, cohort & year disclosed
  • Peer positioning — code breadth — how many codes billed, vs peers

Peer positioning shows billed-volume and code-breadth positions among specialty peers, not measures of care (a provider's true volume position can only be higher, never lower). All figures disclosed Medicare Part B fee-for-service; volumes are personal to this NPI, not attributed to any group.

These are this provider's own Medicare Part B fee-for-service volumes (CMS public data). CMS suppresses rows with fewer than 11 beneficiaries, so low-volume codes may be missing entirely — absence is not zero. Beneficiary-episodes count CMS's per-setting beneficiary figures, not unique patients. Average charge and average Medicare payment are weighted by service volume across office and facility settings. Volumes on this page are personal to the NPI and are not attributed to any physician group. See Methods & Sources.
