Does Medicare Cover Hyperbaric Oxygen Therapy

Yes, Medicare Part B does cover hyperbaric oxygen therapy (HBOT), but this is by no means unconditional. In practice, claims are often stuck on two core thresholds: first, your specific condition must be on the Medicare’s “approved list”; second, the treatment must be recognized as “ medically necessary “.

For patients, in addition to passing the audit, the most realistic problem is actually money-you should know that after paying Part B’s annual deductible , you usually need to pay 20% of the Medicare approved amount out of your own pocket as coinsurance . This means that while Medicare do take on the big head, you’ll still have some out-of-pocket costs. So, what does this mean for you? Let’s take it apart.

Coverage Is Limited to Specific Conditions

The Medicare is very strict in this regard. They have a list of 15 specific conditions in their hands. Only within this range can HBOT treatment be considered effective. In my experience, the most common conditions are usually diabetic foot ulcers that are difficult to heal, tissue damage from radiation therapy, carbon monoxide poisoning, decompression sickness, and certain serious bacterial infections. I want to emphasize one point: if your illness is not on this list, Medicare will not pay the bill.

Currently approved HBOT indications under the Centers for Medicare and Medicaid Services (CMS) include:

Actinomycosis, only as an adjunctive treatment when antibiotics and surgery are ineffective
acute carbon monoxide poisoning
acute peripheral arterial insufficiency
acute traumatic peripheral ischemia
Crush injury and suture of severed limb
cyanide poisoning
decompression sickness
Gas Embolism
gas gangrene
Preparation and preservation of damaged skin flaps
Chronic refractory osteomyelitis unresponsive to conventional medical and surgical treatment
Osteoradionecrosis (as an adjunct to conventional therapy)
progressive necroizing infection
Radiation necrosis of soft tissue (as an adjunct to conventional therapy)
Diabetic wounds of the lower extremities that meet specific criteria

Special Requirements for Diabetic Foot Ulcers

Although HBOT is commonly used to treat diabetic foot, the threshold for Medicare is higher than many people think.

First, your wound must be graded Wagner Class III or higher. Second-and this is where many people are vulnerable to rejections-medical records must prove that after at least 30 days of standard wound care (including debridement, dressing changes, blood sugar control, and nutrition management), the wound has no obvious signs of healing. In other words, HBOT can only be “the last straw”. It can only be considered a “medically necessary” adjuvant therapy if conventional means have failed.

Your Out-Of-Pocket Costs

First, you must first meet the annual deductible for Medicare Part B (this figure changes from year to year). After passing this threshold, Medicare will pay 80% of the approval fee, and you are responsible for the remaining 20%.

That 20 percent may not sound like much, but don’t forget the base number. According to current estimates, the cost of a single hyperbaric oxygen therapy is about $595. This means that for every treatment you do, 20% of your out-of-pocket payment is about $120. Considering that a complete course of treatment often requires as many as 40 treatments. Excluding the deductible, the individual out-of-pocket portion (Coinsurance) of those 40 treatments alone could be closer to $4,800. So before starting treatment, be sure to check that you have supplemental insurance to cover this part of the gap.
