Is Hyperbaric Oxygen Therapy Worth It? An Honest Decision Guide

Here is what some of the key studies found. These are findings from research groups of patients, not promises for any one person. Individual results vary.

Diabetic foot ulcers

In a double-blind randomized trial published in Diabetes Care in 2010, Löndahl and colleagues studied 94 people with chronic diabetic foot ulcers. At one year, 52% of those who received HBOT had complete healing, compared with 29% in the placebo group. The trial was relatively small. A 2015 Cochrane review of HBOT for chronic wounds (Kranke and colleagues) found that HBOT improved diabetic ulcer healing in the short term, at six weeks, but the benefit was not clear at one year, and the effect on major amputation was uncertain.

Radiation injury

The RICH-ART trial (Oscarsson and colleagues, Lancet Oncology, 2019) randomized patients with radiation cystitis, bladder damage after pelvic radiation, across five Nordic centers. Those who received HBOT had greater improvement in urinary symptom scores than those who received standard care alone. The trial was open-label, meaning patients knew which group they were in. For a different use, preventing bone damage before dental extractions in an irradiated jaw, the HOPON trial (Shaw and colleagues, 2019) found no clear benefit, even though that protocol remains widely used. See HBOT for radiation injury.

Sudden hearing loss

A Cochrane review (Bennett and colleagues, 2012) of seven small trials with 392 participants found some evidence that hearing may improve with HBOT, but the evidence was low quality and needs cautious interpretation. The 2019 AAO-HNS guideline lists HBOT with steroids as an option early after onset. Read about HBOT for sudden hearing loss.

HBOT is not cheap, and it is fair to ask why. Published 2026 cost guides put medical-grade sessions at independent centers at about $150 to $450, and hospital outpatient sessions at about $250 to $450. At those prices, a 20-session self-pay course comes to roughly $3,000 to $9,000. These are market ranges, not quotes.

Why HBOT is expensive

A session involves a physician-directed plan, a medical pressure vessel, medical-grade oxygen, trained staff monitoring you, and about 90 to 120 minutes of chamber time. Hospitals also add facility charges.

Why some wellness sessions are cheaper

Wellness or spa sessions, often $75 to $150, usually use soft chambers at about 1.3 ATA, often without physician oversight. That is a different product, not a discount on the same one.

Insurance, HSA and FSA

Insurance, including Medicare, may cover HBOT for certain FDA-cleared indications when specific criteria are met. HSA and FSA funds are generally eligible when HBOT is prescribed by a physician for a medical condition; confirm with your plan administrator.

Generations Wellness currently offers HBOT on a self-pay basis and does not bill insurance today. If you may have a covered indication, tell us. We will explain your options honestly, including when a setting that bills your insurance may make more financial sense. Your pricing is reviewed clearly at your physician consultation. See cost ranges and course math and when insurance may cover HBOT.

"Worth it" should be measured, not guessed. For cleared indications, progress is tracked with objective measures:

• Wounds: size, depth and appearance, measured and photographed at regular intervals. Medicare requires diabetic wounds to be re-evaluated at least every 30 days during HBOT, and coverage ends if there is no measurable improvement in a 30-day period.
• Hearing: repeat hearing tests (audiograms) compared with your baseline.
• Radiation injury: symptom scores and findings from your specialist.

A good plan also has a stopping point: if the measures aren't moving, your physician should reconsider whether to continue. Read how a course is planned and reviewed.

This is a made-up example to show how the four questions work. It is not a patient story.

Imagine a 68-year-old with type 2 diabetes and a deep foot ulcer. Imaging shows infection reaching the bone, which places it at Wagner grade 3. After six weeks of good standard wound care, the wound hasn't measurably improved.

1. Cleared list? Yes. Selected diabetic foot ulcers are an FDA-cleared use.
2. Physician assessment? A physician reviews the wound, circulation, lungs and medications, and coordinates with the wound team.
3. Real HBOT? Treatment would be in a medical-grade chamber at a physician-prescribed pressure.
4. The alternative? A wound that doesn't heal can lead to worsening infection and a higher risk of amputation. That clinical risk is the main thing being weighed, alongside the time and cost of a course.

This person also meets Medicare's criteria for diabetic wounds (Wagner grade 3 or higher, and no measurable healing after at least 30 days of standard care), so a facility that bills Medicare could be an option. In a case like this, the answer to "is it worth it?" may well be yes, with progress checked every 30 days. Change any one fact, such as an ulcer that is healing well on standard care, and the answer could change too.
