What it is
Hyperbaric oxygen therapy, or HBOT, involves breathing oxygen inside a pressurized chamber under the supervision of trained staff. The increased pressure changes how much oxygen the blood can carry. In wound care, the idea is that more oxygen may support tissue in certain hard-to-heal situations.
The FDA has cleared HBOT for a defined list of indications. In general terms, these include certain diabetic foot ulcers, radiation-related tissue injury, and certain serious infections, among others. Uses outside those cleared indications are often called off-label, and they are less likely to be covered.
Insurance coverage is a separate question from FDA clearance. A plan may cover HBOT only when a condition meets its own criteria, when other care has been tried first, and when a physician documents medical necessity. Rules differ by plan, payer and sometimes by location.
How it’s traditionally been approached
Traditionally, HBOT has been delivered in hospital-based or outpatient hyperbaric centers. A physician usually evaluates the patient first to decide whether the therapy fits a recognized indication. Sessions are then scheduled by the treating team.
Because HBOT is typically considered an adjunct, or add-on, to standard wound care, insurers often look at what has already been done. This can include wound assessment, cleaning and debridement, offloading, infection management and circulation checks. Records of these steps commonly support a coverage request.
Many payers use a prior authorization process, meaning approval is requested before treatment begins. Some require ongoing documentation of progress during care. Requirements vary, so the plan's own policy is the most reliable source.
How the right wound care specialist may help
The right wound care specialist or hyperbaric physician may help you understand whether your situation fits a recognized HBOT indication. They can evaluate the wound's cause and stage, review your medical history, and explain whether HBOT is one option among several. They decide what is appropriate; it is never guaranteed to be.
A visit generally includes a wound exam, a review of prior treatments and a conversation about goals. Many centers also have staff who work with insurers on prior authorization and paperwork. This may take some of the guesswork out of the process, though approval is never assured.
Helpful questions to ask a licensed provider: What is causing my wound, and how is it staged? Does my condition fall under an FDA-cleared HBOT indication? What are my other treatment options? What is the expected healing time? What will my plan cover, and what might I owe out of pocket? Can you help with prior authorization and appeals?
The whole-person view
Living with a wound that is slow to heal can be stressful, and stress, sleep, pain and mood can all affect each other. Questions about coverage and paperwork can add to that load. Looking at the whole person, including body, mind and daily routines, is a common way to think about healing support.
Some people explore body-based support such as Somatic Experiences to help them feel more settled in their bodies during a long recovery. Others find talk therapy through Therapists.plus helpful for coping with worry, frustration or health-related stress. These are complementary options to discuss alongside, not instead of, care from your wound care team.

Keep in mind
- Coverage varies widely by plan, condition and location, so confirm details directly with your insurer and your provider; this page does not quote costs or reimbursement.
- HBOT is FDA-cleared only for certain conditions, and only a licensed clinician can decide whether it is appropriate for you after an evaluation.
- Seek medical care promptly for signs of infection such as spreading redness, red streaking, increasing warmth or pain, pus, foul odor, fever or chills, or a wound that is quickly worsening.
- For emergencies such as heavy bleeding, exposed bone or tendon, signs of sepsis, or a deep or severely contaminated wound, call 911 or go to the ER. In a crisis, call or text 988.

Frequently asked questions
Does insurance cover HBOT?
Insurance may cover HBOT when it is used for a condition the plan recognizes and medical necessity is documented. Coverage differs by plan and payer, so it is not universal. A licensed provider and your insurer can tell you what applies to you.
Which conditions does HBOT insurance coverage usually include?
Coverage generally follows FDA-cleared indications, such as certain diabetic foot ulcers, radiation tissue injury and certain infections. Each plan sets its own criteria, which may include prior treatments tried. Ask your provider whether your diagnosis fits your plan's policy.
Is HBOT covered for non-healing wounds?
It may be, but only in specific situations that meet a plan's criteria, not for every slow-healing wound. Insurers often want to see that standard wound care has been tried and documented. A wound care specialist can evaluate whether your wound qualifies.
Do I need prior authorization for hyperbaric oxygen therapy?
Many plans require prior authorization before HBOT begins, though requirements vary. The treating provider's office often submits the documentation. Check with both your insurer and the provider's billing staff.
What if my insurance denies HBOT coverage?
You can generally ask the insurer for the reason in writing and request an appeal. Your provider may be able to supply additional records or a letter of medical necessity. Appeals do not guarantee approval, but understanding the denial is a useful first step.
What should I ask my provider about HBOT and insurance?
Ask about your wound's cause and staging, whether HBOT fits an FDA-cleared indication, other treatment options, expected healing time and what your plan is likely to cover. Also ask who handles prior authorization and what costs you might be responsible for.
