How Much Does Hyperbaric Oxygen Therapy Cost?

HBOT cost at a glance

The price you see depends on the type of HBOT and who pays. Hospital HBOT has published Medicare rates and some published cash prices. Private clinics and wellness centers set their own prices, so ask each one.

ATA means "atmospheres absolute," a measure of pressure. Normal air pressure at sea level is 1 ATA.

Where the Medicare numbers come from

The $140.59 figure is the 2026 national payment rate for G0277 in hospital outpatient departments. The full code description for G0277 is "Hyperbaric oxygen under pressure, full body chamber, per 30 minute interval" (UnitedHealthcare medical policy, 2026). Actual payments are adjusted for local wages, so a hospital in your city may be paid somewhat more or less.

The supervision fee is code 99183, "physician or other qualified health care professional attendance and supervision of hyperbaric oxygen therapy, per session" (same source). CMS gives it 3.28 relative value units for 2026. At the 2026 conversion factor of $33.4009, that works out to about $110 nationally, before geographic adjustment (CMS, 2026). That last step is our arithmetic from the CMS file.

What MDsave cash prices show

MDsave sells prepaid, bundled prices at hospital wound care centers. In October 2026 it listed HBOT visits at 21 providers, from $316 to $1,029 (MDsave, 2026). A few examples from that month:

Read the fine print. One $781 listing says it does not include the physician fee, which is billed separately (MDsave, Grandview Medical Center, 2026). That listing also requires a consultation with the provider first.

Why a full course costs more than one session

A full course is many visits, so the total adds up quickly. Cleveland Clinic says HBOT may be scheduled "once a week or five days a week for up to 30 or more total sessions," and that sessions usually last one to two hours (Cleveland Clinic, 2023).

Some emergencies need few sessions. MedlinePlus notes that treatment for decompression sickness may last longer but may not need to be repeated, while chronic conditions may need sessions over days or weeks (MedlinePlus, 2024).

To estimate your own total, use this:

Total cost = number of sessions × price per session

Ask the clinic for both numbers in writing. Your doctor sets the number of sessions for your condition, so don't assume a typical figure applies to you.

What affects the price of HBOT

Several things move the price up or down:

• Chamber type. A monoplace chamber holds one person. A multiplace chamber holds two or more people, who breathe oxygen through a mask or hood (UnitedHealthcare, 2026). Mild fabric chambers run below 1.4 ATA (same source), well under medical pressures.
• Pressure. The Undersea and Hyperbaric Medical Society (UHMS) defines HBOT as treatment at "not less than 2.0 ATA" with medical-grade oxygen (UHMS, 2020). Mild chambers run lower.
• Setting. Hospitals bill a facility fee plus a physician fee. Private clinics often quote one price.
• Session length. G0277 is billed per 30 minutes, so a longer session means more units.
• City and region. Medicare adjusts its rates by location, and cash prices differ by market, as the MDsave examples show.
• Physician supervision. Some prices include it. Others bill it separately.
• Packages. Some clinics discount a block of sessions. Get the per-session price too, so you can compare.

Cost per session vs per hour vs per package

Clinics quote HBOT in different units, which makes prices hard to compare. Convert everything to the same unit before you decide.

Per 30 minutes or per hour. Hospitals bill G0277 in 30-minute units, which is why you may see hourly prices. At the 2026 Medicare rate, one hour is two units: 2 × $140.59 = $281.18 for the facility, before local adjustment and before the supervision fee.

Per session. A session is one visit, usually one to two hours (Cleveland Clinic, 2023). Ask how many minutes are at full pressure and whether the doctor's fee is included.

Per package. Divide the package price by the number of sessions. Then compare that number with other clinics' per-session prices.

Does insurance or Medicare pay for HBOT?

Sometimes, for specific medical conditions. Medicare Part B may cover HBOT given in a chamber for a set list of conditions, such as carbon monoxide poisoning, decompression illness, radiation injury and certain diabetic foot wounds (Medicare.gov; CMS NCD 20.29).

With Original Medicare, you usually pay 20% of the Medicare-approved amount, and the Part B deductible may apply (Medicare.gov). The 2026 Part B deductible is $283 (Medicare.gov, 2026). As an example, 20% of one $140.59 unit is about $28, before the deductible and local adjustment.

Private coverage varies by plan. Off-label and wellness uses are usually self-pay.

Mild HBOT and wellness clinic pricing

Wellness clinics that offer mild HBOT usually charge cash per session or sell memberships. We found no reliable published price range for these sessions, so ask each clinic.

Mild HBOT is not the same treatment as medical-grade HBOT. UHMS describes mild HBOT as pressures below 1.5 ATA, usually with breathing gas "well less than 95%" oxygen, and calls it unproven (UHMS, 2020). UnitedHealthcare's 2026 policy calls mild HBOT "unproven and not medically necessary for any indication" (UnitedHealthcare, 2026). So expect to pay the full price yourself.

How much does a home hyperbaric chamber cost?

We could not find an independent, reputable source for home chamber prices, so we don't quote a range. Prices you see online come from sellers.

Before you shop, know what these devices are cleared for. One portable soft chamber cleared by the FDA, for example, is intended "to treat acute mountain sickness under the prescription of a health professional," for use in physician offices and health institutions (FDA 510(k) K171899, 2019).

Safety matters too. In 2025 the FDA said it was aware of reports of fires with HBOT devices that caused serious injuries and deaths (FDA, 2025). UHMS warns that mild chamber facilities often skip fire safety and chamber construction standards (UHMS, 2020).

How to save money: questions to ask a clinic

Ask these before you book, and get the answers in writing:

• Is this medical-grade HBOT in a hard-shell chamber, or a mild session?
• What pressure (ATA) will you use, and for how many minutes?
• Who supervises each session, and is that fee included?
• Do you bill my insurance or Medicare? Can you check my benefits first?
• Which billing codes will you use? (For hospital HBOT, usually G0277 and 99183.)
• Is a doctor's consultation included, or billed separately?
• What is the price per session, and what is the package price?
• How many sessions do you expect, and what will the full course cost?

If a clinic can't tell you the pressure or who supervises, that tells you something too. Our guide to what HBOT is explains which conditions it is used for.
