Medicare providers by state

What the counts include

These are unique NPIs in CMS's Medicare Fee-For-Service Public Provider Enrollment file: every individual practitioner, group practice, supplier and facility enrolled to bill Medicare (or only to order and refer) with an enrollment in that state. A provider enrolled in several states is counted in each. The national figure, 2,576,755, counts each NPI once, which is why it is smaller than the sum of the states. Providers who never enroll in Medicare — some therapists, cash-only practices, many dentists — have NPIs but do not appear here.

Each state page breaks the total down by practitioner specialty, and shows each specialty's share of its national count — a quick way to see where, for example, nurse practitioners or physical therapists are concentrated.
