Coverage Criteria for Hyperbaric Oxygen Therapy
inv-01: Systemic HBOT - Medically Necessary Indications
Covered when ALL of the following are met
Evidence and/or UHMS guidelines support these indications; for simultaneous use with negative pressure wound closure, medical criteria for each service must be met via the web-based authorization tool.
inv-02: Topical HBOT - Not Medically Necessary
Not covered when ANY of the following apply
Includes disposable topical chambers and topical oxygen delivery systems (e.g., A4575, E0446). Claims for these products will be denied/not covered.
Topical hyperbaric oxygen therapy is excluded and not covered for BlueCHiP for Medicare and Commercial plans because clinical efficacy has not been established. This exclusion applies to disposable topical chambers and topical oxygen delivery systems and associated supplies (for example, HCPCS codes A4575 and E0446), which are designated as not medically necessary.
Use of hyperbaric oxygen therapy (HBOT) for indications other than those specified in this policy is considered not medically necessary. The available evidence is insufficient to demonstrate that HBOT improves relevant health outcomes for conditions outside the covered indications, and therefore such uses do not meet the policy’s medical necessity requirements.

Provider Actions, Filing & Billing Guidance
Prior Authorization
Prior authorization review is not required.
Provider Filing Note
HBOT is medically necessary when filed with a covered indication. HBOT is not medically necessary for services for all other indications as the evidence is insufficient. For simultaneous use of systemic HBOT and negative pressure wound therapy, medical criteria for each service must be met using the web-based authorization tool.
Diagnosis on Claim
The covered diagnosis must be filed on the claim line to ensure correct claim processing.
Background
Hyperbaric oxygen therapy can be delivered in two ways. Systemic HBOT involves breathing 100% oxygen in a pressurized chamber (typically between 1.5 and 3.0 atmospheres (atm)), allowing systemic circulation to carry oxygenated blood to target tissues. Topical HBOT delivers oxygen directly to an isolated open wound using an enclosure over the wound at pressures slightly above atmospheric pressure. Evidence supporting systemic HBOT exists for selected indications (for example, nonhealing diabetic lower‑extremity wounds, acute traumatic ischemia, radiation‑related soft tissue injury, osteoradionecrosis, gas gangrene, and certain cases of profound anemia), whereas the evidence for topical HBOT is limited (primarily case series and one small RCT) and does not establish clinical benefit.
