Does Medicare Cover Hyperbaric Oxygen Therapy?
Table of Contents
If you’ve ever wondered whether your Medicare plan will cover hyperbaric oxygen therapy, you’re not alone. This treatment—often shortened to HBOT—is renowned for its ability to boost oxygen levels in the blood by using high concentrations of oxygen in a pressurized chamber. But what does Medicare say about the treatment of an illness with HBOT, and under what circumstances does the Medicare program consider it reasonable and necessary? Let’s unpack the details.
Understanding Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy is a procedure in which you breathe 100% oxygen while in a chamber pressurized to levels higher than normal atmospheric pressure. This increased pressure—measured in atmospheres—allows your lungs to absorb an amount of oxygen far greater than that available under regular conditions.
The resulting oxygen-rich blood supply can significantly enhance wound healing and improve blood flow to tissues that need repair. HBOT is a valuable adjunctive treatment used in combination with standard wound care for many medical conditions, such as carbon monoxide poisoning and crush injuries.
Medicare Coverage for HBOT
Medicare Part B (Medical Insurance) may cover hyperbaric oxygen therapy when it is used for specific, FDA-approved medical conditions. These indications include, but are not limited to:
- Acute carbon monoxide poisoning and carbon monoxide poisoning complicated by cyanide exposure
- Decompression sickness
- Crush injuries and acute traumatic peripheral ischemia
- Compromised skin grafts and flaps, where the preparation and preservation of compromised tissue is essential
- Chronic refractory osteomyelitis unresponsive to conventional treatment
- Osteoradionecrosis and soft tissue radionecrosis when used as adjunctive therapy
- Actinomycosis (only when it is refractory to standard antibiotics and surgical treatment)
- Diabetic wounds of the lower extremities that meet strict criteria, including wounds classified as Wagner grade III or higher, and failure to heal with standard wound therapy
In other words, if your medical condition falls under one of these indications, your insurance plan may cover hyperbaric oxygen therapy. It’s important to note that HBOT must be provided in an approved facility by qualified providers. Medicare coverage is determined by the treatment being “reasonable and necessary” for the diagnosis or treatment of the condition.
How Medicare Benefits Work for HBOT
When Medicare covers hyperbaric oxygen therapy, most beneficiaries will have a portion of the cost paid by Medicare Part B. Typically, this means you may pay about 20% of the Medicare-approved amount, with your Medicare Part B deductible applying.
Supplemental policies (often called Medigap) can help with these out-of-pocket expenses. In addition, some Medicare Advantage plans offer the same benefits as Original Medicare but with additional perks, so it’s always wise to check your specific policy details.
Key Conditions and Their Criteria
Below is a table summarizing several key medical conditions for which HBOT is approved under Medicare coverage. This concise guide helps clarify which indications meet the stringent criteria set forth by Medicare:
| Medical Condition | Criteria / Description | Coverage Note |
|---|---|---|
| Carbon Monoxide Poisoning | Acute poisoning requiring urgent treatment to restore oxygen levels in the blood. | Covered when medically necessary. |
| Decompression Sickness | Often occurs in divers who ascend too quickly; treatment must restore oxygen supply and resolve gas emboli. | Covered as an approved indication. |
| Crush Injuries / Acute Traumatic Ischemia | Involves sudden interruption of blood flow due to severe trauma. | Covered as a valuable adjunctive treatment. |
| Compromised Skin Grafts and Flaps | Used when a graft or flap is failing due to inadequate blood flow; healing is tracked using wound measurements. | Coverage depends on documented improvement. |
| Chronic Refractory Osteomyelitis | A bone infection that is non-healing despite conventional treatment methods. | Covered when refractory to standard therapy. |
| Diabetic Wounds of the Lower Extremities | Must meet strict criteria including a wound of Wagner grade III or higher and failure to heal after an adequate course of standard wound care. | Covered if criteria are fully met. |
| Actinomycosis | Only when used as adjunctive therapy and the condition is refractory to antibiotics and surgery. | Covered under limited conditions. |

Navigating Claims and Documentation
For HBOT to be covered, documentation is critical. Your provider must show that there are no measurable signs of healing after at least 30 days of standard wound care—especially for stubborn wounds like non-healing diabetic ulcers. Accurate measurements (often recorded in centimeters) help demonstrate that the treatment is necessary.
What If Your Condition Isn’t on the Approved List?
Medicare covers a defined set of conditions. If your condition—say, Alzheimer’s disease or another off-label use—does not meet the approved criteria, then HBOT might not be covered by Medicare. In such cases, additional research or FDA approval is needed before your insurance can step in.
Additional Considerations
It’s also important to note that simply applying oxygen topically does not count as hyperbaric oxygen therapy. Medicare Part B covers HBOT only when the treatment involves exposing the entire body to high levels of oxygen under increased atmospheric pressure.
Final Thoughts and Your Next Steps
Knowing whether Medicare covers hyperbaric oxygen therapy can help you feel more confident in your treatment decisions. If you or a loved one is considering HBOT for an approved condition like carbon monoxide poisoning, crush injuries, or non-healing diabetic wounds, make sure your healthcare provider documents your progress carefully.
