Is Hyperbaric Oxygen Therapy (HBOT) Covered by Insurance?

The short answer: yes — at participating centers, for the right conditions. MD Hyperbaric now accepts insurance, including Medicare, at participating centers for on-label conditions: the medical indications for which hyperbaric oxygen therapy is an established, evidence-based standard of care. For other conditions, and at non-participating centers, HBOT remains a self-pay treatment with flexible pricing and FSA/HSA options.

This guide explains how HBOT insurance coverage actually works — which diagnoses qualify, what your insurer will expect, what happens if your condition is off-label, and how to find out where you stand before your first session.

A quick refresher: what is HBOT?

Hyperbaric oxygen therapy involves breathing 100% medical-grade oxygen inside a pressurized chamber, typically at 2.0–2.4 times normal atmospheric pressure. The pressure dissolves far more oxygen into your blood plasma than normal breathing can, delivering oxygen to tissue that injury, infection, or damaged circulation has left oxygen-starved.

The FDA recognizes a defined set of medical indications for HBOT, and for those conditions it is established standard care — the kind insurers reimburse. A growing body of research also supports HBOT for a range of off-label uses, from post-surgical recovery to long COVID; those uses are generally not reimbursed by insurance.

Which conditions does insurance cover?

Insurers — including Medicare — cover HBOT for the on-label indications, when treatment is medically necessary for your diagnosis. The recognized list:

1. Air or gas embolism
2. Carbon monoxide poisoning (with or without cyanide poisoning)
3. Gas gangrene (clostridial myositis and myonecrosis)
4. Crush injury, compartment syndrome, and other acute traumatic ischemias
5. Decompression sickness
6. Arterial insufficiencies (central retinal artery occlusion; selected problem wounds, including diabetic foot ulcers)
7. Severe anemia
8. Intracranial abscess
9. Necrotizing soft tissue infections
10. Refractory osteomyelitis
11. Delayed radiation injury (soft tissue and bony necrosis)
12. Compromised skin grafts and flaps
13. Acute thermal burn injury
14. Idiopathic sudden sensorineural hearing loss

Being on this list is necessary but not automatic: coverage also depends on your specific plan and on medical-necessity criteria. For example, diabetic foot ulcers generally qualify at Wagner Grade 3 or higher after 30 days of standard wound care, and delayed radiation injury typically requires documentation that conventional therapy was tried first. A qualified provider assembles this documentation as part of the intake process.

Where MD Hyperbaric accepts insurance

Our participating centers are in-network providers and accept insurance — including Medicare — for the on-label conditions above. Contact your nearest center to confirm whether it currently participates. Here’s how it works:

1. Contact the center — or ask your physician to send a referral.
2. We verify your benefits. As an in-network provider, we confirm coverage for your diagnosis and explain your expected costs — deductible, copay, coinsurance — before treatment begins.
3. We handle authorization. Most plans require prior authorization before treatment starts; our team coordinates it with your physician and your insurer. For time-sensitive conditions like sudden sensorineural hearing loss, we run an expedited pathway so authorization doesn’t cost you the treatment window.

At our other centers, HBOT remains self-pay for now — if you’re near a participating center, it may be worth the trip for a covered course of treatment.

When HBOT is not typically covered

Insurance does not generally reimburse HBOT for off-label uses, even well-researched ones. That includes:

• Cognitive and neurological support (including concussion and TBI recovery)
• Post-surgical and athletic recovery
• Long COVID support
• Chronic fatigue and general wellness
• Anti-aging and longevity protocols

These classifications reflect insurance policy, not necessarily the state of the research — the evidence base for several off-label uses is substantial and growing. At MD Hyperbaric, off-label treatment is self-pay under the supervision of our Medical Director, with the same chambers, protocols, and safety standards as covered care.

Paying for off-label or self-pay treatment

If your condition is off-label, or you’re visiting a non-participating center, you still have options:

• FSA/HSA funds. Most FSA and HSA plans allow payment for physician-recommended HBOT — see our complete FSA/HSA guide.
• Superbills for out-of-network claims. For self-pay treatment we can provide a superbill on request — an itemized statement with the diagnosis and procedure codes your insurer needs — so you can submit an out-of-network reimbursement claim. Reimbursement is at your plan’s discretion and is uncommon for off-label indications, so treat it as a possibility rather than a plan.
• Flexible pricing. Pay-as-you-go per-session rates, plus package options at reduced rates when purchased upfront.
• Good Faith Estimates. If you’re uninsured or self-paying, you’re entitled to a written Good Faith Estimate of expected charges before treatment — see our Good Faith Estimate notice.

What to ask your insurance provider

If you want to check your coverage yourself before calling us, ask your insurer:

• Is HBOT (CPT/HCPCS hyperbaric oxygen therapy) a covered benefit under my plan?
• Does my diagnosis meet your medical-necessity criteria for HBOT?
• Do I need prior authorization, and what documentation is required?
• Is there a limit on the number of covered sessions?
• What will my deductible, copay, or coinsurance be?

Or skip the phone tree: contact your nearest MD Hyperbaric center and we’ll verify your benefits for you.

The bottom line

HBOT coverage used to mean hospital wound-care centers or nothing. That’s changed: participating MD Hyperbaric centers now offer in-network, insurance-covered HBOT for on-label conditions — with the accessibility, scheduling, and patient experience of a dedicated private center. And for everything else, we remain committed to making medically guided HBOT accessible through transparent self-pay pricing.
