Source: CMS NPPES, primary taxonomy 133V00000X by practice state, file of Aug 9, 2026; records per 100,000 residents, 2023 Census estimates.
5.4% of these records appear in a Medicare file, against 7.4% nationally
A Medicare file here is Part D prescribing (2024), a MIPS score (2023), an Open Payments record (2024) or Medicare group billing (CMS Doctors and Clinicians). A record outside them may still see patients: these files cover Medicare only.

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
