Hyperbaric Oxygen Therapy in California: How to Find a Provider

Hyperbaric oxygen therapy (HBOT) is available across California at hospital-based wound care centers, academic medical centers, and standalone hyperbaric clinics. California is one of the largest states for HBOT access, with providers in most major metro areas. Here’s how to find an accredited provider near you.

Where to Find HBOT in California

California has more HBOT providers than most states. Knowing the types helps you choose wisely.

Check HBOT benefits with the specific payer and treating facility. FDA device clearance and UHMS clinical recommendations do not establish insurance eligibility. Medicare uses NCD 20.29; other plans have their own criteria. Confirm diagnosis-specific requirements, provider eligibility, authorization and patient costs in writing before scheduling. See the insurance guide.

Academic medical centers in cities like Los Angeles, San Francisco, and San Diego often have formal hyperbaric medicine programs. University-affiliated hospitals tend to follow strict clinical protocols.

Standalone clinics may offer both medical and wellness HBOT. Verify credentials carefully before booking. Not all clinics use medical-grade chambers or have a physician on staff.

The best starting point: use the UHMS (Undersea and Hyperbaric Medical Society) provider search at uhms.org. It lists accredited facilities across the state.

What to Ask a Potential Provider

Before you commit, ask every provider these questions.

• Is this a medical-grade hyperbaric chamber (2.0 ATA or higher)?
• Is there a board-certified or credentialed hyperbaric physician on staff?
• Is my condition FDA-approved for HBOT?
• Does your facility work with my insurance for prior authorization?
• Is the facility UHMS-accredited?

If a clinic can’t answer these clearly, that’s a red flag. Read our guide to your first HBOT session for more on what to expect.

Insurance Coverage for HBOT in California

Insurance rules for HBOT in California follow national standards with a few things to know.

Medicare Part B covers HBOT when the diagnosis and treatment meet CMS NCD 20.29 and applicable provider and setting requirements. This applies in California just as it does in every other state.

California Medicaid (Medi-Cal) coverage for HBOT varies by condition and plan. Check directly with the facility’s billing department before scheduling.

Commercial insurers like Blue Shield of California, Anthem, Aetna, Cigna, and UnitedHealthcare generally follow Medicare coverage criteria. Prior authorization is almost always required.
