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.
