TMS access by state, 2026: clinics per capita, devices, insurance and prices.

What we counted

Every listing in the TMS List clinic directory located in the 50 states or the District of Columbia, as the directory stood on October 26, 2026. Each location of a multi-site practice is its own listing. The headline measure counts confirmed TMS sites: listings that name a TMS device, or that have TMS (or transcranial magnetic stimulation) in the practice name. That is 1,498 of the 3,196 listings (46.9%).

The other 1,698 listings are psychiatry and mental-health practices whose listing shows neither signal. Many of them do offer TMS, so the “All listings” column and CSV field report them too, at 0.94 per 100,000 nationally. Treat the confirmed count as a floor and all listings as a ceiling.

Exclusions

Of 4,127 US listings in the directory file, 786 were taken down after a review found they are not TMS providers (physical therapy, primary care and similar practices whose websites do not mention TMS). Practices that asked to be removed from the directory are not counted either. 9 listings located outside the 50 states and DC (Puerto Rico, and a few with addresses abroad) are left out. A further 136 listings with no TMS device and no psychiatry or mental-health signal in their name or business categories are excluded. 3,196 listings remain.

Population

Resident population on July 1, 2024 from the U.S. Census Bureau, Population Division, Vintage 2024 estimates (NST-EST2024, column POPESTIMATE2024; census.gov, data file). The 51 values sum to the published US total of 340,110,988. Rates use the whole population, not only adults or people with depression.

Definitions

Sites per 100k: confirmed sites ÷ population × 100,000. Device brand: the listing’s device field names NeuroStar, BrainsWay (including “Deep TMS”), MagVenture or another manufacturer; generic entries such as “FDA-cleared TMS” do not count. Device percentages are shares of sites that name a brand, and a site can name more than one. Insurance: the listing names at least one accepted insurer. Price: the listing gives a dollar figure per session or per course. Weekend hours: posted office hours include a Saturday or Sunday time range; listings showing “Open 24 hours” (facility hours, mostly hospitals) are left out of that measure.

Minimum samples

State percentages are shown only when at least 10 sites are in the base; smaller states show “—”. Price statistics need at least 5 priced sites at any level. With 4 nationally, none are reported.

Limitations

A listing is a location, not capacity: it says nothing about how many chairs, clinicians or appointment slots a site has. The directory is compiled from public sources (device-maker clinic locators, public business profiles, provider registries) and from clinic submissions. It misses sites that appear in none of these, and not every listing has been checked by our team. Device names come largely from manufacturer locators, which favours the brands that publish one. Small states have few sites, so one opening or closure moves their rate a lot. Hospitals and health systems offering TMS inside a larger department may be undercounted.

Updates and corrections

This is the 2026 edition, frozen at the October 26, 2026 snapshot so the figures stay citable. Directory pages update continuously and may show different counts. Clinics can correct their listing through the provider portal; spotted an error in the study? Contact us.
