• Methodology

This page comes from public files the Centers for Medicare & Medicaid Services publishes each year: the Medicare Physician & Other Practitioners files, which list the Part B services each clinician billed to Original Medicare, and the Doctors and Clinicians files, which list group and hospital affiliations. It covers Original Medicare fee-for-service only: Medicare Advantage, Medicaid and commercial insurance are not in these files, and CMS leaves out any service line with fewer than 11 beneficiaries. The location and specialty are what the claims show, and affiliations are as of the snapshot date, so either can lag a recent change. A listing here says nothing about quality of care.
