What Is UHMS? The Organization Behind Hyperbaric Medicine Standards
The Undersea and Hyperbaric Medical Society approves HBOT indications, trains physicians, and accredits facilities. Here's how it works and why it matters.
The UHMS — Undersea and Hyperbaric Medical Society — is why HBOT has standardized indications, trained physicians, and accredited facilities rather than just being another unregulated wellness treatment. Founded in 1967, it’s the professional body that gave the field its clinical credibility.
What UHMS Does
The Society’s four main functions define the structure of modern hyperbaric medicine.
It evaluates evidence and publishes clinical indications. The UHMS indications page describes its recommendations. These are separate from FDA device labeling and Medicare NCD 20.29; one list must not be substituted for another.
UHMS provides professional education. Membership, facility accreditation and physician board certification are different credentials; verify a claimed certification with its issuing board.
It accredits facilities. UHMS facility accreditation means a site has been reviewed against peer-developed standards covering equipment safety, physician supervision requirements, staff training, and clinical protocols. Accreditation alone does not establish compliance with all applicable professional, facility and safety requirements. But accreditation is the meaningful quality signal for patients trying to distinguish clinical facilities from wellness spas.
It publishes and hosts an annual scientific conference. The UHMS Annual Scientific Meeting is the primary professional gathering for the field, where new research is presented and clinical standards are updated.
How UHMS Relates to FDA and Medicare
Three separate organizations address different aspects of HBOT, and their roles are often confused.
FDA regulates hyperbaric chambers as medical devices. Chambers require 510(k) clearance before commercial sale. FDA can also act against providers who make false or misleading claims about HBOT. See FDA approval vs. 510(k) clearance for a full explanation.
UHMS evaluates clinical evidence for indications. When evidence supports a new indication, the UHMS list is updated. UHMS doesn’t control FDA or Medicare — it publishes the evidence review that informs them.
Medicare establishes coverage through NCD 20.29, with its own indications and restrictions. UHMS recognition does not automatically establish Medicare coverage.
These three systems — device regulation (FDA), evidence evaluation (UHMS), and payment policy (Medicare) — operate independently but inform each other.
Why the Facility Accreditation Matters to You
Wellness centers offering HBOT at lower pressure for biohacking and recovery may or may not be UHMS-accredited. A wellness purpose does not remove device instructions or safety requirements.
For medical treatment, ask the treating clinician about device suitability, supervision, staff qualifications and safety procedures. Check any claimed accreditation directly; accreditation is not a guarantee of outcomes or payment.
The easiest way to find accredited facilities is the UHMS directory at uhms.org. Filter by your state or city to see what’s nearby. Our provider directory also lists HBOT facilities by location.
The UHMS Indications Document
UHMS publishes an indications overview and details about its indications manual at uhms.org. It’s updated when clinical committee reviews warrant a change. Reading it directly is the best way to understand the current evidence standard for each approved indication rather than relying on summaries.
The document addresses both what the evidence supports and what it doesn’t. For anyone evaluating HBOT for a specific condition, it’s worth reading the relevant section before making a treatment decision.
FAQ
Does UHMS accreditation guarantee good outcomes? Accreditation confirms a facility meets established safety and process standards. It doesn’t guarantee clinical outcomes. Treatment results depend on many factors including the specific condition, patient health, and treatment protocol.
How do I check if a specific facility is UHMS-accredited? Use the facility directory at uhms.org. If a facility claims accreditation, you can verify it through the UHMS directly.
Can a solo physician operate a UHMS-accredited facility? Accreditation requirements specify physician oversight and staff training standards. The specific requirements for solo practices versus larger programs are detailed in the UHMS accreditation standards, available from UHMS on request.
Is UHMS membership the same as UHMS accreditation? No. A physician or facility can be a UHMS member without being accredited. Accreditation involves a formal review process separate from membership.
