What they bill and prescribe

Published Medicare data for 2024, measured over the 633 active individual prevention professional on file nationally on 2026-10-05 — a different base from the records above, and the same measurement the data page publishes for every specialty.

With published prescribing1 of the 633 active individual prevention professional on file
under 1%

Published Medicare fee-for-service data for 2024, covering about one in 633 clinicians nationally, and more in the specialties that bill it most — not all-payor claims, and low-volume providers are removed before publication. A provider with nothing there has no published Medicare volume, which covers no volume, volume below the publication threshold and not billing Medicare at all — the published data does not separate them, and one year is held, so nothing here is a trend.

A high share here means the published Medicare data covers that specialty well. It says nothing about how complete our contact data is for it — different datasets, measured over different populations — and the email, phone and location fill rates are counted and published separately on the same page.
