How we check clinic listings

As of October 26, 2026, HBOTmap lists 737 hyperbaric oxygen therapy (HBOT) clinic locations in the United States. You can browse them by state. This page explains where the details on a listing come from and how we check them, so you can judge how far to trust them. When we can't find a detail, we leave it blank instead of guessing.

Updated November 2, 2026

Where do the details come from?

Each listing is one clinic location. A chain with five locations gets five listings. We list a location when a public source says it offers HBOT, usually the clinic's own website. The 737 are the locations we've found, not every place in the US that offers HBOT. If we're missing one, tell us at the address at the end of this page.

We built the list from public business listings, directories and clinic websites. We check clinics' own websites, with help from AI tools, for details such as services, hours, prices and insurance (our editorial policy explains how we use them). When sources disagree about a clinic's own details, like its prices or hours, we go with its website. For accreditation by the Undersea and Hyperbaric Medical Society (UHMS), we go with the UHMS list. On a clinic's page you'll find source links inside its sections and under "Sources and listing information", with the date we checked a detail where we have it. Every listing was checked at least once between September 5 and October 25, 2026.

Clinics change their prices, hours and services. Before you book, confirm the details with the clinic.

How do we check prices?

Between September 5 and October 25, 2026, we checked prices for 654 of our 737 locations. We found a price for 142 of them, about 1 in 5:

What we foundClinic locations
A price on a public page142
Checked, found no public HBOT price496
Checked, no price we could use for HBOT16
Not checked for price yet83

We record the prices a clinic posts for HBOT: single sessions, packages and memberships, plus related fees such as a consultation. They come from the clinic's website, its online booking page or a public price list. We didn't search hospitals' price-transparency files. With each price we save the page and the date, plus:

  • the session length the clinic gives,
  • conditions such as "first visit only" or "members only",
  • whether the clinic calls it mild HBOT, and any pressure it states.

Search results show a clinic's single-session price when it posts one. If it posts only packages or memberships, the card says "Prices listed", and the details are on the clinic's page. We never show a package, membership or consultation fee as a session price.

Pressure matters because UHMS treats mild and medical HBOT as different things. Pressure is measured in ATA (atmospheres absolute), and 1 ATA is normal air pressure at sea level. In its guidelines revised in April 2026, UHMS defines mild HBOT as pressure below 1.5 ATA, and says treatments with scientific support are usually given at 1.9 to 3.0 ATA1.

So we label a price mild when the clinic calls it mild or states a pressure below 1.5 ATA. Most other HBOT prices state no pressure at all, so a price without the mild label may still be for a lower-pressure session. Our guide How much does HBOT cost? keeps those prices apart from the ones that state a pressure.

If a clinic's page shows no prices, we either found no usable public price or haven't checked yet. It doesn't mean free or expensive, and we never fill the gap with an average. Ask the clinic for a quote.

How do we check insurance?

We record what a clinic's website says about insurance: the plans it names, a general "we accept insurance", billing or policy notes, or self-pay only. As of October 26, 2026, 207 of our 737 listings have an insurance note. For the other 530, we either found nothing on the clinic's website (44) or don't have a confirmed answer yet (486). Those listings show no insurance detail rather than a guess.

A clinic accepting insurance doesn't mean your plan covers HBOT there. Coverage depends on your plan and your diagnosis. As of October 2026, Medicare covers HBOT only for a set list of conditions, and only when the patient meets that policy's requirements2. Check with the clinic and your insurer before you start.

How do we check accreditation?

UHMS accredits hyperbaric facilities against its own standards. A listing gets the "UHMS accredited" mark only when the facility appears on the UHMS list of accredited facilities3. We read the July 2026 list on September 8, 2026, and 100 of our listings matched it, so the mark reflects that check. UHMS updates its list as facilities gain or lose accreditation, so a facility's status may have changed since the July 2026 list. If it matters to you, check the current UHMS list.

A clinic saying it's accredited isn't enough for the mark. When a clinic's own website reports an accreditation, such as from The Joint Commission, we show it as the clinic's statement, with the page it came from.

What about chambers, conditions and hours?

About 300 listings include chamber details, such as a hard or soft chamber. We show the pressure when the clinic states it. Hours, which 688 listings have, come from the clinic's website or its public business listing.

The conditions on a listing (675 listings have them) are the ones the clinic names on its own site. They mean the clinic offers HBOT for them, not that we think HBOT works for them. Our guide Understanding HBOT explains what the research says.

How do listings stay current?

We don't recheck listings on a fixed schedule yet. Instead we run checks of one detail at a time, like the price check above, and we recheck a listing when someone reports a change. When we confirm that a location has closed or no longer offers HBOT, we take its listing down.

What don't we do?

  • We don't rank clinics or call any clinic the best. You can sort results by name or by distance.
  • We don't charge clinics to be listed, and no clinic pays for its place in results. We don't run ads.
  • We don't visit clinics or inspect their equipment or staff. A listing shows what the clinic and other public sources say. It isn't our approval of its care.
  • No doctor or other medical professional reviews our listings or pages yet.
  • Clinics can't edit their own listings. When a clinic sends a correction, we check it against a public page before we change anything.

Found a mistake?

Email support@hbotmap.com with the clinic's name or its HBOTmap page, what's wrong, and a link that shows the right detail if you have one. We check it. If the listing was wrong, we fix it and update its checked date. Clinics can use the same address. How we write and correct our guides is in our editorial policy, and more about the site is on our about page.
