All figures are disclosed (CMS suppresses fewer-than-11-beneficiary rows) Medicare Part B fee-for-service — a subset, never complete totals; volumes are personal to this NPI, not attributed to any group. Standing is a billed-volume position among specialty peers with disclosed billing (national percentile; a provider's true standing can only be higher, never lower), not a statement about care.

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.
