The single most common question we get: "Will Medicare pay for this?" The answer is a clear yes — if your condition and documentation meet the national coverage rules. Here is how it actually works.
The covered list
Medicare's National Coverage Determination 20.29 covers hyperbaric oxygen for conditions including diabetic lower-extremity wounds (Wagner grade III or higher, unresponsive to 30 days of standard care), delayed radiation injury to soft tissue and bone, chronic refractory osteomyelitis, compromised skin grafts and flaps, gas gangrene, crush injuries, decompression sickness, air embolism, and severe carbon monoxide poisoning.
The documentation that matters
Coverage denials almost always come down to paperwork, not eligibility. For a diabetic wound, for example, Medicare wants to see the wound grade, evidence of 30 days of standard care that failed, and physician oversight of the treatment plan. Good clinics build that file from day one.
What you will actually pay
With Original Medicare, Part B typically covers 80% after your deductible; a supplement plan usually covers the rest. Medicare Advantage plans follow the same coverage rules but may require prior authorization — which we handle.
The honest part
Off-label uses — concussion recovery, long COVID, wellness protocols — are not covered by Medicare or private insurance, period. Anyone who implies otherwise is setting you up for a bad surprise. We quote self-pay costs upfront instead.
