Does Medicare Cover Hyperbaric Oxygen Therapy?

Does Medicare Cover Hyperbaric Oxygen Therapy?

Medicare Part B may cover hyperbaric oxygen therapy when it is medically necessary for one of the conditions included in Medicare’s national coverage policy. The therapy must be administered inside a qualifying hyperbaric chamber and meet all applicable medical, documentation and provider requirements.

Medicare does not cover HBOT for every condition. It also does not generally pay for home hyperbaric chambers purchased for personal wellness, recovery or self-directed use.

When HBOT is covered, the patient usually pays 20% of the Medicare-approved amount after meeting the Part B deductible. Medicare Advantage, Medigap and other supplemental coverage may affect the final out-of-pocket cost.

What Is Medicare’s Policy on Hyperbaric Oxygen Therapy?

The Centers for Medicare & Medicaid Services defines HBOT as a therapy in which the entire body is exposed to oxygen under increased atmospheric pressure.

Under Medicare National Coverage Determination 20.29, reimbursement is limited to therapy administered inside a chamber, including a single-person chamber, for specified medical conditions.

Coverage generally requires:

• A Medicare-covered diagnosis
• Medical necessity
• An order from a treating healthcare professional
• Treatment from a Medicare-participating provider
• Appropriate supervision
• Correct billing and diagnosis codes
• Documentation supporting the treatment
• Compliance with any condition-specific requirements

Having a condition on the Medicare list does not guarantee that every claim will be approved. The provider must document that the treatment satisfies the coverage criteria.

What Conditions Does Medicare Cover HBOT For?

Medicare’s national policy lists 15 covered indications:

1. Acute carbon monoxide intoxication
2. Decompression illness
3. Gas embolism
4. Gas gangrene
5. Acute traumatic peripheral ischemia
6. Crush injuries and suturing of severed limbs
7. Progressive necrotising infections, including necrotising fasciitis
8. Acute peripheral arterial insufficiency
9. Preparation and preservation of compromised skin grafts
10. Chronic refractory osteomyelitis unresponsive to conventional treatment
11. Osteoradionecrosis as an adjunct to conventional treatment
12. Soft-tissue radionecrosis as an adjunct to conventional treatment
13. Cyanide poisoning
14. Actinomycosis that is refractory to antibiotics and surgery
15. Qualifying diabetic wounds of the lower extremities

Several of these indications are covered only when HBOT is used alongside conventional treatment. The treating provider must document why hyperbaric oxygen therapy is medically necessary.

Does Medicare Cover HBOT for Diabetic Wounds?

Medicare covers HBOT for certain diabetic wounds of the lower extremities, but the patient must meet three specific criteria:

• The patient has type 1 or type 2 diabetes.
• The patient has a lower-extremity wound caused by diabetes.
• The wound is classified as Wagner grade III or higher.

The patient must also have completed at least 30 consecutive days of standard wound care without measurable signs of healing.

Standard wound care may include:

• Assessment of blood flow
• Treatment of vascular problems where possible
• Glucose control
• Nutritional support
• Removal of devitalised tissue
• Appropriate dressings
• Pressure off-loading
• Treatment of infection

HBOT must be provided in addition to standard wound care rather than replacing it. Medicare requires the wound to be reassessed at least every 30 days. Continued HBOT is not covered if measurable healing is not demonstrated during a 30-day treatment period.

How Much Does Medicare Pay for HBOT?

Medicare’s HBOT coverage page states that patients usually pay 20% of the Medicare-approved amount. The Medicare Part B deductible may also apply.

The exact cost depends on:

• Whether the deductible has been met
• The Medicare-approved rate
• Number of covered sessions
• Treatment setting
• Provider participation
• Additional physician or facility charges
• Medigap coverage
• Medicare Advantage plan terms

If a provider accepts Medicare assignment, it agrees to accept the Medicare-approved amount for covered services. A Medigap policy may cover some or all of the remaining Part B coinsurance, depending on the plan.

Ask the provider for an estimate of the Medicare-approved amount, expected coinsurance and any separate facility fees before treatment begins.

Does Medicare Advantage Cover HBOT?

Medicare Advantage plans must cover at least the medically necessary services covered by Original Medicare. Therefore, a Medicare Advantage plan may cover HBOT for eligible conditions.

However, Medicare Advantage plans can apply their own administrative requirements, including:

• Prior authorisation
• In-network provider rules
• Referrals
• Different copayments or coinsurance
• Treatment reviews
• Session limits
• Additional documentation

Contact the plan directly before beginning a non-emergency course of HBOT. Ask whether the facility and supervising physician are in-network and whether prior approval is required.

Does Medicare Cover Home Hyperbaric Chambers?

Medicare does not generally cover the purchase of a home hyperbaric chamber for personal wellness, athletic recovery or other self-directed use.

Medicare’s national coverage policy focuses on HBOT administered inside a chamber as a medically necessary professional service for a listed condition. A home chamber is not automatically covered as durable medical equipment.

Someone interested in home HBOT should ask Medicare or their Medicare Advantage plan for a written coverage decision before making a purchase. Do not assume that a physician’s recommendation alone guarantees reimbursement.

What HBOT Uses Does Medicare Not Cover?

Medicare does not cover HBOT for conditions outside its covered indications under the national policy.

CMS specifically lists several non-covered uses, including:

• General skin ulcers not meeting the diabetic-wound criteria
• Chronic peripheral vascular insufficiency
• Thermal skin burns
• Myocardial infarction
• Sickle cell anaemia
• Multiple sclerosis
• Arthritic diseases
• Pulmonary emphysema
• Organ transplantation
• Alzheimer’s disease and other specified chronic brain syndromes

This does not mean HBOT cannot be discussed or used outside Medicare’s covered indications. It means Original Medicare will not reimburse HBOT for those uses under its national coverage policy.

Topical oxygen therapy is treated separately. Local Medicare Administrative Contractors may make certain coverage decisions for topical oxygen used for chronic non-healing wounds.

How Do You Confirm Medicare Coverage Before HBOT?

Before starting treatment, take the following steps:

1. Ask the treating physician whether your diagnosis meets Medicare’s HBOT criteria.
2. Confirm that the physician and facility participate in Medicare.
3. Ask whether prior authorisation or additional documentation is required.
4. Request the diagnosis and procedure codes the provider expects to bill.
5. Contact Medicare or your Medicare Advantage plan.
6. Ask for an estimate of your deductible, coinsurance and facility charges.
7. Keep copies of medical records, treatment plans and coverage decisions.
8. Confirm how progress will be documented if ongoing coverage depends on improvement.

Medicare beneficiaries can call 1-800-MEDICARE for personalized coverage information. Medicare Advantage members should also contact their plan administrator.

What Can You Do If Medicare Does Not Cover HBOT?

If Medicare does not cover HBOT for your intended use, you can ask the provider about self-pay rates and treatment packages.

For long-term or frequent access, purchasing a chamber may also be worth considering. Oxygen Health Systems supplies chambers for home and professional environments, with US-based technical assistance, a three-year warranty and professional installation options.

Eligible buyers can explore providers such as Oxygen Health Systems and their financing options; rather than an upfront purchase, you can spread the cost over an agreed period. HSA or FSA reimbursement may also be possible when HBOT is recommended for a qualifying medical purpose and supported by appropriate documentation.

These alternatives do not change Medicare’s coverage rules, but they can provide additional ways to access HBOT when treatment is not reimbursed.
