Key findings

  • Missouri registers 337.3 active providers per 100,000 residents. That ranks 38 of 51 jurisdictions, below the national 433.5. #
  • St. Louis city has the state's highest registered density (894.5 per 100k); 15 of Missouri's 115 counties have fewer than 3 registered providers. #
  • Counselors are the largest group at 45.3% of Missouri's registered workforce (US: 43.9%). #
  • 1,219 providers with a Missouri practice address first entered the NPI registry in 2025, versus 995 in 2019. These are registry entries, not licenses issued. #
  • 61% of Missouri providers share a registered practice location with six or more in-scope providers. #

Providers per 100,000 by county

Providers are allocated to counties from their practice ZIP code. For 15 counties with under 3 allocated providers or under 1,000 residents, we show the count but no per-100k rate, because numbers that small don't make a reliable rate. We also withhold the rate for one county (St. Francois), where a single practice address holds at least half the providers registered there — typically a regional employer that enrols its whole clinical staff at one headquarters, which inflates that county and thins its neighbours. The same values appear in the table.

When Missouri's providers entered the registry

Active providers by NPI registry-entry year. Registry entry is not licensure. Clinicians typically register when they start billing, so this measures registrations, not the workforce itself. 2026 is a partial year.

Reading these numbers

Counts are NPPES registrations at Missouri practice addresses. They are headcounts, not FTEs or license tallies. Telehealth and multi-state practice are invisible; taxonomy self-designation is not license verification; the registry lags moves and retirements. Details: methodology.
