33,183 providers across 433 specialties

How to read this directory

This count includes every individual clinician, physicians, dentists, nurse practitioners, physician assistants, therapists, and psychologists, with a current active National Provider Identifier on file with the Centers for Medicare & Medicaid Services and a primary practice address in Maine. Organizations such as hospitals, group practices, and pharmacies carry their own separate NPPES records and are deliberately not included in this individual-provider total, and each clinician is counted once under their registered primary taxonomy. Every figure is drawn from the federal National Provider Identifier Registry (CMS NPPES) - more than 7 million providers, maintained since May 2007, with 2023 Medicare Part D data, and, according to CMS, can be searched, compared, and traced in our methodology.

Important: this is a directory of public CMS government data, not a quality ranking, a review aggregator, or medical advice. NPPES records are self-reported and refreshed monthly, so a listed address or phone number can lag reality; always call the office to confirm location, insurance acceptance, and new-patient availability before booking. Verify licensure and disciplinary history, which are not shown here, through the NPI Registry and your state medical board.

Using the Maine data

Maine has 33,183 active registered providers, here is how to act on that.

  • Narrow by specialty first: Maine's provider mix differs from the national distribution, and the per-specialty pages show who actually practices here. Browse specialties
  • Verify any shortlisted provider's federal record and license before booking, registration alone is not a quality signal. NPI lookup
  • Check Maine's disciplinary-action trends to understand the state board's enforcement context. Board actions

Counts reflect CMS NPPES registrations, which can lag retirements and relocations. PlainDoctor does not rate, rank, or recommend providers.
