Coverage Overview
Does Insurance Cover HBOT?
Whether insurance covers hyperbaric oxygen therapy depends on several factors, including the medical condition being treated, the type of insurance plan, and the specific insurer's policies. In general, HBOT is most likely to be covered when it is prescribed for one of the 14 conditions that the FDA has cleared for hyperbaric treatment and when a physician documents medical necessity.
Medicare, Medicaid, and many private insurance plans provide coverage for HBOT when used to treat FDA-cleared indications. Coverage typically requires a physician's prescription, a documented diagnosis, and in many cases, pre-authorization from the insurance provider. The scope of coverage, including the number of sessions approved and the reimbursement rate, varies between plans and providers.
For off-label uses of HBOT, such as wellness, athletic recovery, or anti-aging protocols, insurance coverage is generally not available. However, the growing body of research supporting HBOT for various conditions means that coverage policies continue to evolve. It is always worth checking with your specific insurance provider for the most current coverage details related to your condition and treatment plan.
Federal Coverage
Medicare Coverage for Hyperbaric Oxygen Therapy
Medicare Part B covers hyperbaric oxygen therapy for 14 FDA-approved conditions. Coverage requires that the treatment be ordered by a physician and performed in an approved facility using an FDA-cleared hyperbaric chamber. Below are the 14 conditions for which Medicare provides HBOT coverage.
Air or Gas Embolism
Treatment for air or gas bubbles in the bloodstream, which can occur during surgical procedures or diving accidents.
Carbon Monoxide Poisoning
HBOT accelerates the removal of carbon monoxide from the bloodstream by replacing it with oxygen under pressure.
Gas Gangrene (Clostridial Myonecrosis)
A serious bacterial infection of muscle tissue where elevated oxygen levels help inhibit the growth of anaerobic bacteria.
Crush Injuries and Acute Traumatic Ischemias
HBOT supports oxygen delivery to tissue compromised by crushing force, helping reduce swelling and support tissue viability.
Decompression Sickness
The primary treatment for "the bends" experienced by divers, where HBOT helps dissolve nitrogen bubbles in the blood.
Arterial Insufficiency (Central Retinal Artery Occlusion)
Used to improve oxygen supply in cases of acute peripheral arterial insufficiency and certain types of sudden vision loss.
Severe Anemia (Exceptional Blood Loss)
When blood transfusion is not an option, HBOT provides oxygen delivery through dissolved plasma oxygen rather than hemoglobin.
Intracranial Abscess
HBOT supports treatment of brain abscesses by enhancing oxygen delivery to the infected area and supporting immune response.
Necrotizing Soft Tissue Infections
Used as adjunctive therapy for serious soft tissue infections, where elevated oxygen helps inhibit bacterial growth and supports healing.
Osteomyelitis (Refractory)
For chronic bone infections that have not responded to standard treatment, HBOT supports antibiotic effectiveness and bone healing.
Delayed Radiation Injury
HBOT helps promote new blood vessel growth in tissue damaged by radiation therapy, restoring blood flow to irradiated areas.
Compromised Skin Grafts and Flaps
When skin grafts or surgical flaps show signs of failure, HBOT supports tissue oxygenation to improve graft survival.
Acute Thermal Burn Injury
HBOT supports treatment of severe burns by reducing swelling, supporting tissue oxygenation, and helping prevent infection.
Diabetic Foot Ulcers (Wagner Grade III or Higher)
One of the most common Medicare-covered HBOT indications, used for non-healing diabetic foot wounds that have not responded to standard wound care.
Medicare coverage may also extend to Medicaid recipients in many states. Coverage specifics, including the number of approved sessions, vary by region and individual circumstances. Always verify coverage with your Medicare representative or healthcare provider before starting treatment.
Private Plans
Private Insurance Coverage for HBOT
Many private insurance plans cover hyperbaric oxygen therapy for FDA-cleared medical conditions. However, coverage policies, reimbursement rates, and pre-authorization requirements vary significantly between insurers and individual plan types. Understanding your plan's specific terms is essential before beginning HBOT treatment.
Employer-Sponsored Plans
Many employer-sponsored health plans include coverage for HBOT when treating FDA-cleared conditions. These plans typically require pre-authorization and a documented medical necessity from the prescribing physician. Coverage details are outlined in your plan documents or can be confirmed by calling the member services number on your insurance card.
Individual and Marketplace Plans
Individual insurance plans purchased through the health insurance marketplace may cover HBOT for FDA-cleared indications. Coverage varies by plan level and insurer. Review your plan's summary of benefits or contact your insurer directly to determine whether HBOT is a covered service under your specific plan.
Veterans and Military Coverage
The Department of Veterans Affairs (VA) provides HBOT for eligible veterans for approved medical conditions. TRICARE, the military health plan, also covers HBOT for FDA-cleared indications when administered in authorized facilities. Service members should check with their regional VA center or TRICARE representative for details.
Workers Compensation
In many states, workers compensation insurance covers HBOT when a work-related injury or condition falls within the FDA-cleared indications. Coverage typically requires documentation linking the condition to the workplace injury and a physician prescription. Consult with your workers compensation administrator for specific coverage details.
Tips for Maximizing Insurance Coverage
- Confirm that your diagnosis falls within the FDA-cleared indications for HBOT before initiating treatment.
- Request a written letter of medical necessity from your prescribing physician that outlines why HBOT is the appropriate treatment.
- Verify that the treating facility and chamber are FDA-cleared and meet your insurer's requirements for approved providers.
- Submit pre-authorization requests as early as possible and keep copies of all correspondence with your insurer.
- Ask your physician's office or the hyperbaric facility for assistance with insurance documentation, as many have experience navigating the authorization process.
Step-by-Step
How to Get Insurance Approval for HBOT
Securing insurance coverage for hyperbaric oxygen therapy involves several key steps. Following this process carefully can significantly improve your chances of getting HBOT approved and covered by your insurance plan.
Get a Physician Prescription
The first step is to obtain a written prescription for HBOT from a licensed physician. The prescription should include your specific diagnosis, the clinical rationale for hyperbaric therapy, and the recommended treatment protocol, including the number of sessions and pressure level. A diagnosis that falls within the 14 FDA-cleared conditions significantly increases the likelihood of insurance approval.
Obtain Pre-Authorization
Contact your insurance provider to request pre-authorization for HBOT. Most insurers require prior approval before treatment begins. During this process, you will typically need to provide your physician's prescription, your diagnosis code (ICD-10), and any supporting medical documentation. Your physician's office or the hyperbaric facility may assist with this step, as they are often experienced in working with insurance companies.
Document Medical Necessity
Insurance companies require documentation showing that HBOT is medically necessary for your condition. This typically includes medical records showing previous treatment attempts, diagnostic imaging or wound measurements, lab results, and a detailed letter of medical necessity from your physician. The stronger the documentation, the more likely your claim is to be approved. Include any relevant peer-reviewed literature that supports HBOT for your specific condition.
Submit Claims and Follow Up
After your pre-authorization is approved and treatment begins, ensure that claims are submitted correctly with the appropriate CPT codes for hyperbaric therapy. The treating facility will typically handle claim submission, but it is wise to track each claim and verify that your insurer is processing payments as expected. If a claim is denied, request a detailed explanation and work with your physician to submit an appeal with additional supporting documentation.
Alternative Options
When Insurance Does Not Cover HBOT
While insurance coverage for FDA-cleared conditions is widely available, many people seek HBOT for wellness, recovery, anti-aging, or other off-label purposes that are not covered by insurance. In these cases, there are several pathways to access hyperbaric oxygen therapy without relying on insurance reimbursement.
Off-label use of HBOT refers to any application that falls outside the 14 FDA-cleared conditions. This includes wellness protocols, cognitive enhancement, athletic recovery, anti-aging, and general health optimization. While research continues to explore the potential benefits of HBOT across these areas, insurance companies generally do not cover treatments that are considered investigational or elective.
Clinic Sessions (Pay Per Visit)
Many hyperbaric clinics and wellness centers offer HBOT on a per-session basis for individuals paying out of pocket. This approach allows you to try HBOT without a large upfront investment. However, because most treatment protocols involve 20 to 40 sessions, the cumulative cost of clinic visits can become significant over time. Contact local facilities for session availability and pricing details.
Financing Through Brickhouse Capital
OxyHealth partners with Brickhouse Capital to offer flexible financing for hyperbaric chamber purchases. With terms ranging from 24 to 60 months and up to 100% financing available, purchasing a home chamber becomes an accessible option for many families and individuals.

Long-Term Value
Owning a Chamber vs. Clinic Visits
For individuals who plan to use HBOT on an ongoing basis, owning a home hyperbaric chamber can provide significant long-term value compared to paying for individual clinic sessions. Understanding the differences between these two approaches helps inform the best decision for your needs.
Clinic Visits
Per-Session Model
- Pay per session with no upfront investment
- Access to clinical-grade equipment and trained staff
- Requires travel time and appointment scheduling
- Cumulative costs increase over multiple treatment protocols
- Session availability may be limited by facility hours
- Each session adds to the total cost of treatment
Owning a Home Chamber
Unlimited Access Model
- Unlimited HBOT sessions with no per-session costs
- Treat on your own schedule from the comfort of home
- Multiple family members can benefit from a single chamber
- OxyHealth portable chambers are FDA-cleared and easy to set up
- Flexible financing makes ownership accessible with monthly payments
- Long-term value increases with every session completed at home
The right choice depends on your treatment goals, frequency of use, and budget. For occasional use, clinic visits may be sufficient. For ongoing wellness protocols or chronic conditions requiring regular treatment, owning a chamber typically provides greater convenience and long-term value. Contact OxyHealth to discuss which approach is right for your situation.
