Editorial policy

We use AI tools to help draft and check our guides, and no page has had a medical review yet. Here's where our facts come from, how we check them, and how to tell us when we get something wrong. Use it to judge how far to trust what you read here. For the clinic listings themselves, see how we check clinic listings.

Who writes HBOTmap?

HBOTmap is a small, independent directory of hyperbaric oxygen therapy (HBOT) clinics in the United States. You can read more about HBOTmap or browse clinics by state. Our pages go out under the HBOTmap name rather than people's names. Our job is to help you find and compare clinics and understand what you're paying for. We don't treat anyone, and nothing here is medical advice.

Which sources do we use?

For research, we start with systematic reviews, which use set rules to find and judge the studies that fit a specific research question1. Reviews from Cochrane, which publishes a handbook for this kind of review, come first.

Next come randomized trials, which assign people by chance to the groups being compared2. We find studies through PubMed, the research database run by the US National Library of Medicine3.

For medical guidance, we use the Undersea and Hyperbaric Medical Society (UHMS) and the Food and Drug Administration (FDA). For coverage, we use the Centers for Medicare & Medicaid Services (CMS) and insurers' published coverage policies.

In guides we publish or update from November 2026, we check each research finding against the published study. When the full paper isn't free to read, we use its abstract, the short summary shown on PubMed, and we say so. Facts about insurance coverage, or about what the FDA has cleared a device for, come from the official record, or we say whose statement we're quoting.

When we use our own data, like the prices in our cost guide, we give the count and the dates we checked.

Clinic websites tell us what a clinic offers and charges. We never use them as evidence that a treatment works.

Every guide we publish or update from November 2026 follows these rules:

  • When we describe a study, we give how it was set up, its size, the pressure it used, how long people were followed and its main limit.
  • When we say how good the evidence is, we use one of the four labels below, and each points to its source.
  • We keep FDA clearance, Medicare or insurer coverage, and UHMS recommendations apart, and say which one we mean.
  • Results from a high-pressure medical chamber aren't applied to mild HBOT, or the other way round.
  • Outside facts link to their source.

For the basics of what HBOT is and what it's used for, start with Understanding HBOT.

How do we rate the evidence?

  • "Strong evidence" means a well-done systematic review, or several good randomized trials, found clear and consistent results.
  • "Some evidence" means at least one good randomized trial, or smaller studies that point the same way.
  • "Early or limited evidence" means there are only small or early studies, or studies without a comparison group.
  • "No good evidence" means there are no good trials, or the good ones found no clear benefit.

How are guides made?

Each guide starts with a practical question, like how much a session costs. Where our own data can answer it, we use it.

AI tools do much of this work. They help us read clinic websites, sort the data, draft pages, and check our figures against our data and outside facts against their sources. Then two separate AI reviewers, from two different companies, check each draft for wrong facts, unsafe health claims and unclear writing. From November 2026, a guide, or a policy page like this one, goes up only after both reviewers pass it. Clinic listings, and the state and city pages built from them, come from our data instead; how we check clinic listings explains those.

If the reviewers disagree about a fact, the original source settles it. If it's still unclear, we say so or leave the claim out.

Is there medical review?

Not yet. No page on HBOTmap has been reviewed by a doctor or other medical professional. We plan to add a hyperbaric physician or certified hyperbaric nurse to review our pages about conditions and safety. Once a page has had that review, it will name the reviewer, their credential and the date. Until then, we stick to reporting what official bodies and published studies say.

If you're thinking about HBOT, talk to your doctor about whether it's right for you.

How do we stay independent?

HBOTmap is self-funded, and the site doesn't earn any money.

  • No clinic pays to be listed, to appear higher in results or to be mentioned in a guide.
  • There are no ads, and we don't earn commissions from clinics or chamber sellers.
  • Clinics don't see or approve our pages before we publish them.
  • A clinic is named in a guide only for a sourced, neutral fact, such as a posted price. We don't rank clinics.

How do we keep pages current?

Our guides show the date they were last updated or checked. Prices, coverage rules and guidelines change. In guides we publish or update from November 2026, we date any fact that can go out of date, with "as of" or the date we checked it. We plan to recheck each guide at least every three months. When we learn a fact has changed, we update the page and its date.

How do we correct mistakes?

If you spot an error, email support@hbotmap.com with the page, what's wrong and a source if you have one. We check it. If we got it wrong, we fix it. When a correction changes a fact in a guide, we add a short dated note at the end of that guide saying what changed. Typo fixes don't get a note.

To fix a clinic listing, use the same address; how we check clinic listings explains what we need.
