Cost & Insurance
How Much Does Hyperbaric Oxygen Therapy Cost?
Nationally, medical-grade HBOT commonly costs $150 to $450 per session outside hospitals, and a typical course is 20 to 40 sessions. Here is what drives that price, what a full course adds up to, and how self-pay works at Generations Wellness.
The National Picture
HBOT Cost Per Session: The National Ranges
There is no single price for hyperbaric oxygen therapy. What you pay per session depends mostly on where you're treated and what kind of chamber is used. Published 2026 cost guides put the typical self-pay ranges here:
| Setting | Typical self-pay per session | What to know |
|---|---|---|
| Hospital outpatient department | $250–$450 | Listed chargemaster rates can reach $1,000–$2,500 before discounts. |
| Independent medical-grade center | $150–$450 | Hard-shell chambers, physician-supervised. Many fall between $150 and $250. |
| California hard-shell centers | $350–$700 | Higher regional costs push California prices above the national middle. |
| Wellness or spa soft chamber | $75–$150 | Usually about 1.3 times normal pressure on air. This does not meet the medical definition of HBOT. |
One directory, hbotguide.com, lists an average of about $250 per session for Modesto. That figure is a regional estimate, not a price from any specific center.
What Generations Wellness charges
We treat patients in hard-shell monoplace chambers under the direction of Dr. Rajwinder Singh Bahia, MD, and we currently offer HBOT on a self-pay basis. Because the number of sessions and the treatment plan depend on your condition, we give you your pricing clearly at your physician consultation, before you commit to anything. To ask about current self-pay pricing, call (369) 222-0979.
Course Math
What a Full Course Costs: 20 vs. 40 Sessions
HBOT is rarely a single visit. For the conditions HBOT is cleared for, a physician commonly recommends 20 to 40 sessions, usually one a day, five days a week. That makes the course total the number that really matters. The table below simply multiplies session count by three common per-session prices.
| Sessions | At $150 per session | At $250 per session | At $350 per session |
|---|---|---|---|
| 20 sessions | $3,000 | $5,000 | $7,000 |
| 30 sessions | $4,500 | $7,500 | $10,500 |
| 40 sessions | $6,000 | $10,000 | $14,000 |
At $150 to $450 per session, a 20-session course comes to roughly $3,000 to $9,000 and 40 sessions to roughly $6,000 to $18,000. Your physician sets the session count and reviews your progress along the way, so the course can be adjusted as your tissue responds. That's also why no one should prepay for 40 sessions before a physician has assessed whether HBOT is appropriate.

Behind the Numbers
Why HBOT Prices Differ So Much
Chamber type and pressure
The Undersea and Hyperbaric Medical Society (UHMS) defines HBOT as breathing near-100% oxygen inside a chamber pressurized to at least 1.4 times normal atmospheric pressure (1.4 ATA). Every UHMS-recognized indication calls for 2.0 ATA or more. Soft-sided "mild" chambers typically run at about 1.3 ATA on regular air, which is why they cost less, and why they are not interchangeable with medical HBOT. See how hard-shell and soft-shell chambers differ.
Hospital vs. independent center
Hospital outpatient departments carry facility overhead that independent centers don't. Published cost guides estimate that uninsured patients often pay 30–60% less at an independent center for a comparable session. For a fuller comparison, read hospital vs. independent HBOT centers.
Physician supervision and staffing
Medical HBOT is supervised. In billing terms, physician attendance is its own service (CPT code 99183), separate from the facility charge for chamber time (HCPCS G0277, billed per 30-minute interval). That supervision, along with trained staff monitoring every session, is part of what you are paying for.
Session length and course length
A typical session runs about 90 to 120 minutes including pressurization and depressurization. Longer sessions and longer courses cost more in total, which is why the course total, not the per-session price, is the fairer comparison between centers.
Paying for Care
Self-Pay and Insurance: Which Applies to You
Generations Wellness currently offers HBOT on a self-pay basis while we work toward insurance contracts. That means we do not bill insurance or Medicare today, and we will tell you so plainly before you begin.
It is still worth knowing how coverage works in general. Insurance, including Medicare, can cover HBOT for certain FDA-cleared indications when specific medical criteria are met. Medicare's rules are set out in National Coverage Determination 20.29. For a selected diabetic foot ulcer, for example, the wound must be Wagner grade 3 or higher and must have shown no measurable healing after at least 30 days of standard wound care. Uses outside the covered list are self-pay everywhere.
At facilities that do bill Medicare, patients typically pay the Part B deductible ($283 in 2026) and then 20% coinsurance. Published estimates put that at roughly $90 to $115 per session. That is a general range, not a quote.
If you think you may have a covered indication, tell us when you call. We will explain your options honestly, including when another setting may make more financial sense for you. For the details, read whether insurance may cover HBOT and Medicare's HBOT coverage criteria.

Questions
HBOT Cost: Frequently Asked Questions
How much does hyperbaric oxygen therapy cost per session?
Nationally, medical-grade HBOT commonly runs $150 to $450 per session at independent centers and $250 to $450 in hospital outpatient departments. Spa-style soft chambers cost less because they are not medical HBOT. We review your pricing clearly at your consultation.
How much does a full course cost without insurance?
At $150 to $450 per session, 20 sessions come to roughly $3,000 to $9,000 and 40 sessions to roughly $6,000 to $18,000, depending on setting. Your physician sets the session count, so your total depends on your plan.
Do you accept insurance or Medicare?
Not yet. We currently offer HBOT on a self-pay basis while we work toward insurance contracts. Insurance and Medicare can cover HBOT for certain FDA-cleared indications when criteria are met, so if that may apply to you, ask us and we'll explain your options honestly.
Can I use my HSA or FSA for HBOT?
Generally yes, when HBOT is prescribed by a physician for a medical condition. Confirm eligibility with your plan administrator before you start.
Why are some HBOT centers so much cheaper?
Lower prices often reflect soft-sided chambers running at about 1.3 ATA on air, which do not meet the medical definition of HBOT. Hospital facility fees push prices the other way. Compare chamber type and physician supervision, not just the price.
