What the Physician Report contains

Show details3 known limitations

Included

  • Exact Medicare payment figures for each data year
  • Calculated Medicare fee-for-service work RVUs for each data year
  • Historical results for every data year with usable data
  • Peer comparisons: rank, percentile and rank band among the same specialty, the peer medians, and where the physician falls in the peer distribution
  • Beneficiaries, services, service mix and code-level lines
  • A printable report with the data years, methodology and limitations

Not included

  • Other physicians' figures and ranks
  • The market's cohort table, percentile table and market trend (the Market Comparison)
  • Peer comparison flags (professional subscription, not sold)

Known limitations

  • CMS suppresses code lines with fewer than 11 beneficiaries, so calculated work RVUs are a floor.
  • 2018: fewer than 20 peers in the metro, so ranks and percentiles use national peers (3,263).
  • 2019: fewer than 20 peers in the metro, so ranks and percentiles use national peers (3,584).

About this data

Show details

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.
