Source and method
Data: NPPES Data Dissemination file (National Plan and Provider Enumeration System), published by CMS as public domain data, snapshot of June 2026. Each provider is counted once, in the state and city of the Provider Business Practice Location, under the primary taxonomy declared in the NPI record itself. Only active NPI records are counted.
Important: an active NPI does not mean the professional is currently practicing, accepting new patients or even still working in the field; it only means the registration number remains valid. This page publishes aggregate counts only, never individual records.
