Medicare & hyperbaric oxygen therapy

What Medicare actually covers

Hyperbaric oxygen therapy is covered under Medicare Part B as an outpatient service, governed by National Coverage Determination NCD 20.29. This is a national policy, so the covered-condition list is the same in every state.

Coverage is not open-ended. For each condition, Medicare expects documentation that the clinical criteria were met — for diabetic foot ulcers, for example, a Wagner grade III or higher wound that has failed at least 30 days of standard wound care.

What you would pay

Under Part B, after your annual deductible is met, Medicare pays 80% of the approved amount and you are responsible for the remaining 20% coinsurance. A Medigap or supplemental policy often covers that share; Medicare Advantage plans handle it differently and usually require prior authorization through the plan rather than through Medicare directly.

We verify your specific plan before anything is scheduled, so the number you hear from us is the number you pay.

What Medicare will not cover

This is where most clinics are vague, so plainly: Medicare does not cover HBOT for concussion or post-concussion syndrome, long COVID, athletic recovery, anti-aging or longevity use, autism, or cerebral palsy. Those are off-label. Some are genuinely promising and under study — but they are self-pay, and any clinic implying otherwise is misleading you.

How we handle it

• You tell us your condition and your plan.
• We verify benefits directly with Medicare or your Advantage plan — free, no obligation.
• We tell you what is covered, what is not, and what your share would be, in writing.
• Only then do we schedule anything.
