A single hyperbaric session at a wellness or recovery clinic usually runs somewhere between $99 and $250 depending on how long you're in the chamber, and you pay for it yourself.
That number confuses people, because if you search around for a few minutes you'll also find articles quoting $20,000 and up. Both are accurate. They're describing two completely different things that happen to use the same equipment, and once you see the split, the pricing stops being mysterious.
The Quick Answer
- At a recovery or wellness clinic, expect to pay per session, out of pocket. At Defiant in Lisle, IL, a 30-minute session is $99, 60 minutes is $185, and 90 minutes is $225. New clients can try a first 30-minute session for $49.
- At a hospital wound care center, hyperbaric oxygen is billed to insurance as a medical treatment, and the full course is what costs five figures. A 2024 analysis of Medicare reimbursement data put a single session at $595.86 in 2022. Courses average around 26 sessions, and a full 40-session course came to $23,834.40.1
- Insurance covers the hospital version only for specific diagnoses. Medicare's national coverage policy lists 15 conditions it will pay for and names 22 more it explicitly won't.2 Using a chamber for recovery or general wellness isn't on either list, because it was never under consideration.
- Nobody bills insurance for a recovery session, including us. Hyperbaric at Defiant is self-pay.

Two Markets, One Machine
Hyperbaric oxygen therapy means breathing oxygen at greater-than-normal atmospheric pressure inside a sealed chamber. The physics work the same way wherever you do it, but the billing runs on two entirely separate tracks depending on why you're in the chamber.
On one side you have hospital-based hyperbaric medicine, which treats things like diabetic foot ulcers, radiation injury to bone and soft tissue, and carbon monoxide poisoning. Those patients are referred by a physician, treated on a daily schedule for weeks, and their insurance is billed per session. On the other side you have recovery and wellness clinics, where people book an hour in a chamber the way they'd book a sauna or a massage, and pay at the front desk.
| Hospital wound care center | Recovery / wellness clinic | |
|---|---|---|
| Who goes | Referred patients with a qualifying diagnosis | Anyone who books |
| Typical course | Around 26 sessions on average, up to 40 or 601 | One session at a time, or an ongoing routine |
| How it's paid | Billed to insurance per session | Self-pay at time of service |
| Pressure | Usually 2.0 to 3.0 ATA | Commonly up to 2.0 ATA |
| What it costs | $595.86 per session to Medicare in 20221 | $99 to $225 per session at Defiant |
Searching "how much does hyperbaric oxygen therapy cost" pulls answers from both columns at once, which is why the results look like they disagree.
What Insurance Actually Pays For
Medicare's national coverage determination for hyperbaric oxygen therapy, NCD 20.29, is unusually blunt for a policy document. It lists 15 covered conditions, including acute carbon monoxide intoxication, decompression illness, gas embolism, gas gangrene, crush injuries where loss of limb or function is threatened, progressive necrotizing infections, chronic refractory osteomyelitis, osteoradionecrosis, compromised skin grafts, and diabetic lower-extremity wounds that meet three specific criteria.2
It then names 22 conditions it will not pay for under any circumstances, which is a level of specificity most coverage policies don't bother with. That list includes thermal burns, sickle cell anemia, multiple sclerosis, arthritic diseases, and Alzheimer's and other non-vascular causes of chronic brain syndrome.2 The policy language is direct: no program payment may be made for any conditions other than those listed.
Private insurers largely follow this framework, though each carrier writes its own rules. If you're pursuing coverage for a qualifying medical condition, start that conversation with your physician and your plan, since a wellness clinic has no way to move it forward for you.
The FDA, separately, has cleared hyperbaric chambers for a specific list of conditions including carbon monoxide poisoning, decompression sickness, gas embolism, gas gangrene, crush injuries, certain non-healing wounds, radiation injury, severe anemia, compromised skin grafts, and sudden hearing or vision loss.3 Recovery, training load, and general wellness are not cleared indications. The FDA has also said plainly that hyperbaric chambers are not proven to treat cancer, Lyme disease, autism, or Alzheimer's disease, and it warns consumers away from clinics that claim otherwise.3
We think you should know all of that before you spend money on a session, including a session with us.
What the Covered Version Costs
The best public numbers on medical hyperbaric pricing come from a 2024 short communication in Undersea and Hyperbaric Medicine, which analyzed 262,055 sessions recorded across 53 centers in the Hyperbaric Oxygen Therapy Registry between 2013 and 2022.1
Adjusted to 2022 dollars, the authors estimated a single session at $595.86, combining the hospital facility fee (billed in four 30-minute segments) with the supervising physician's fee.1 A full 40-session course came to $23,834.40, down 15.6% from $27,561.74 in 2013, with most of that decline coming from physician reimbursement falling 37.8% over the decade.1 Costs by condition ranged from $2,383.44 for a short crush-injury protocol up to $35,751.60 for a 60-session course for diabetic foot ulcers or delayed radiation injury.1
A note on the source, since we'd rather you hear it from us. That study was funded by Regenerative and Hyperbaric Medicine Inc. and by the registry it analyzed, and its stated conclusion is that hyperbaric therapy costs less than the literature has suggested.1 The underlying reimbursement figures come from published Medicare fee schedules and are verifiable, so the arithmetic holds up, but read the framing with that funding in mind.
The structure is the point. Medical hyperbaric runs into five figures because it's dozens of supervised sessions stacked up over weeks, and any single hour in a chamber is a fairly ordinary line item.
What Drives the Price of a Wellness Session
Cash-pay hyperbaric pricing varies more than most services, and the variation is usually explained by four things.
Session length. Most clinics price 30, 60, and 90-minute options. Longer sessions cost more, and per-minute they usually cost less.
Chamber type and pressure. A hard-shell chamber that reaches 2.0 ATA is a different piece of equipment from an inflatable soft-shell unit, which typically tops out around 1.3 ATA. Hard-shell chambers cost more to buy, install, and maintain, and that shows up in session pricing. We wrote a full comparison of hard-shell versus soft-shell hyperbaric chambers if you want the detail.
Staffing. Someone has to run the chamber, monitor pressurization, and be there the whole time. A clinic with trained staff on the chamber charges differently than a self-serve setup.
Packages and memberships. Almost nobody does one hyperbaric session and stops. Clinics know that, so the single-session price is often the highest per-session rate available.
If you see a price well under the local range, ask what pressure the chamber reaches and who's supervising during the session. A session that costs half what everyone else charges is usually running in a soft-shell chamber at lower pressure, or without staff present, and both of those are worth knowing before you book.
HBOT Pricing at Defiant in Lisle
We publish our prices on the hyperbaric oxygen therapy page, and here they are in one place.
| Session | Price | New client |
|---|---|---|
| 30 minutes | $99 | $49 |
| 60 minutes | $185 | $99 |
| 90 minutes | $225 | Not offered |
New clients get a discounted first session at either length, $49 for 30 minutes or $99 for 60. Those sessions run in an OxyHealth 64D hard-shell multiplace chamber that seats two people and reaches up to 2.0 ATA, so you can bring someone with you. The 60-minute session is the one most people settle into.
Hyperbaric at Defiant is self-pay. We don't bill insurance for it, and we don't currently accept HSA or FSA cards for it either.
When a Membership Costs Less Than a Session
Defiant membership at the Premier tier is $150 a month, and one 60-minute hyperbaric session is included each month as your Premium Recovery credit. A 60-minute session on its own is $185.
So if hyperbaric is already part of your monthly routine, the membership costs less than the single thing you were going to buy anyway, and it comes with three additional Core Wellness credits you can spend on cryotherapy, a vitamin shot, a Styku scan, a sauna session, or a few other options. The Elite tier at $250 a month includes two Premium Recovery credits.
Read the terms before you sign up. Memberships require a three-month commitment and credits expire after 30 days, so the value only holds if you'll actually come in. Paying twelve months up front gets you two free.
HSA, FSA, and the Paperwork Question
The answer splits along the same line the pricing does. For an FDA-cleared medical indication, prescribed by your physician and delivered at a facility that bills insurance, hyperbaric oxygen therapy is generally treated as a medical expense, and your plan decides the rest from there.
For a recovery or wellness session with no diagnosis behind it, you're paying out of pocket. At Defiant specifically, hyperbaric sessions are self-pay and we don't take HSA or FSA cards for them. If your account administrator handles things differently, ask them before you book rather than after you've paid.
What to Ask Before You Hand Over a Card
Five questions that will tell you most of what you need to know about any hyperbaric clinic's pricing:
- What pressure does your chamber actually reach, in ATA?
- Is it hard-shell or soft-shell?
- Is staff present and monitoring for the whole session?
- What does the price drop to with a package or membership, and do credits expire?
- Do you make any claims about treating specific diseases? If yes, be skeptical, and check the answer against the FDA's cleared list.
- Wellness and recovery hyperbaric sessions are priced per session and paid out of pocket, typically $99 to $250 depending on length. At Defiant in Lisle, IL, sessions are $99, $185, and $225, and new clients start at $49.
- Hospital-based hyperbaric medicine is the version that costs five figures, because a course averages around 26 sessions and can run to 60.1
- A 2024 registry analysis estimated a single medical session at $595.86 to Medicare in 2022 and a 40-session course at $23,834.40, down 15.6% from the 2013 cost of the same 40-session course.1
- Medicare's NCD 20.29 covers hyperbaric therapy for 15 named conditions and explicitly excludes 22 others.2 Recovery and general wellness fall outside the covered list entirely.
- Chamber type is the main thing separating one clinic's price from another's. Hard-shell chambers reaching 2.0 ATA cost more to run than soft-shell units around 1.3 ATA, and the session price reflects that.
- If hyperbaric is a monthly habit, a membership including a 60-minute session can cost less than buying that session outright.
Frequently Asked Questions
Try It Before You Budget For It.
A first 30-minute session in our hard-shell 2.0 ATA chamber is $49 for new clients, which is a cheaper way to find out whether hyperbaric belongs in your routine than reading another pricing article.
