What's distinctive here

The specialties Ohio has more, and fewer, of than the nation

Relative to its size, Ohio has about 10.1× the national share of homemakers and only 0.31× the share of behavior technicians. These gaps reflect how each state licenses and classifies professions, not how much care is available.

Each multiple is Ohio's share of that specialty divided by its national share, among specialties with at least 3,000 providers in-state. Source: CMS NPPES, current release.

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 Ohio. 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 Ohio data

Ohio has 316,004 active registered providers, here is how to act on that.

  • Narrow by specialty first: Ohio'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 Ohio's disciplinary-action trends to understand the state board's enforcement context. Board actions
