Coverage, without
the confusion.
The honest version: Medicare and most major insurers cover HBOT for the FDA-recognized indications, and almost never for off-label uses. We'll check your specific situation for free — before you commit to anything.

We work with your plan
For FDA-recognized indications, we verify your specific benefits — free — before anything is scheduled.
Aetna
Covers recognized indications per its Clinical Policy Bulletin; requires documentation mirroring NCD 20.29. Off-label uses considered experimental.
Blue Shield
Commercial plans generally follow Medicare's indication list with prior authorization. Off-label uses (e.g. TBI, long COVID) are excluded.
Cigna
Aligns with Medicare's covered indications; prior authorization and periodic reauthorization for extended wound courses.
Medicaid / Medi-Cal
Follows Medicare's recognized-indication list; specifics and prior-auth vary by state. In California, Medi-Cal generally aligns with NCD 20.29.
Medicare
Covers the 14 UHMS-recognized indications under NCD 20.29 (plus diabetic lower-extremity wounds meeting Wagner III+ / 30-day criteria). Part B pays 80% after deductible. Documentation of failed standard care is the usual denial point.
UnitedHealthcare
Covers recognized indications with prior authorization; medical-necessity review common for wound-care courses beyond initial approval.
Typically covered
Medicare-recognized indications
Under Medicare's national coverage policy (NCD 20.29), these conditions qualify when clinical criteria are met — most private insurers follow similar lists:
- Air or Gas Embolism
- Carbon Monoxide Poisoning
- Central Retinal Artery Occlusion
- Compromised Grafts & Flaps
- Crush Injury & Compartment Syndrome
- Decompression Sickness
- Delayed Radiation Injury

Off-label uses are self-pay
Concussion recovery, long COVID, athletic recovery, longevity — insurers don't cover these today. We'll tell you the real cost upfront on our costs page, never mid-treatment.
