Hyperbaric oxygen therapy (HBOT) is a technique of delivering higher pressures of oxygen to the tissues and is now used for a variety of medical conditions (air embolism, acute traumatic injury, thermal and radiation injuries, infections and complicated wound management) that have potential to respond to increased oxygen delivery to the tissues. There are two methods of administration currently available:
Systemic Hyperbaric Oxygen Administration:
Systemic hyperbaric oxygen therapy involves breathing 100% oxygen at an elevated (i.e. greater than sea level) atmosphere absolute (ATA) of at least 1.4, although pressure is typically between 2 and 3 ATA. Individuals typically spend one to two hours in the chamber per session as determined by the professional provider. It is generally applied with the patient inside a hyperbaric chamber, either a monoplace or multiplace chamber. This technique relies on systemic circulation to deliver highly oxygenated blood to the target site, typically a wound. In addition, systemic HBOT can be used to treat various systemic illnesses.
- Monoplace Chamber: This accommodates a single patient, the entire chamber is pressurized with near 100% oxygen and the patient breathes the ambient chamber oxygen directly.
- Multiplace Chamber: This holds two or more people (patients, observers, and/or support personnel), the chamber is pressurized with compressed air while the patients breathe near 100% oxygen via masks, head hoods or endotracheal tubes.
Hyperbaric oxygen therapy is used in the treatment of acute and chronic diseases and conditions in which oxygen delivery to tissue has been compromised by traumatic injury, infection, inflammation, or edema (swelling). The delivery of oxygen to the body under hyperbaric conditions, therefore, raises tissue oxygen levels and promotes recovery. The mechanisms of action for hyperbaric oxygen therapy include displacing gas, decreasing edema, aiding the growth of new blood vessels (angiogenesis) and/or connective tissue (fibroblast proliferation), and killing bacteria.
Potential risks for individuals undergoing hyperbaric oxygen therapy includes pressure related traumas (e.g. barotraumatic otitis, pneumothorax, middle ear effusion, and tympanic membrane rupture) and adverse effects (e.g. myopia, seizures) due to oxygen toxicity. Refraction changes are common but usually resolve once treatment is concluded. Hypoglycemia may be induced in diabetic individuals undergoing hyperbaric oxygen therapy. Rapid ascent from pressure may cause decompression illness. Some individuals may experience claustrophobia due to the confined chamber space.
Documentation regarding hyperbaric oxygen therapy should include the hyperbaric procedure logs with ascent time, descent time and pressurization level. In addition, there should be a treatment plan identifying timeline and treatment goals.
The evidence for the use of systemic HBOT in individuals with decompression sickness, acute carbon monoxide poisoning, gas gangrene, compromised skin grafts or flaps, prophylactic pre-operative and post-operative treatment for patients undergoing dental surgery (non-implant related) of an irradiated jaw, chronic non-healing wounds, profound/severe anemia with exceptional blood loss, only when blood transfusion is impossible or must be delayed, acute cyanide poisoning, air or gas embolism, progressive necrotizing infections (necrotizing fasciitis), acute peripheral arterial insufficiency, osteomyelitis refractory to conventional medical and surgical management, acute traumatic ischemia (e.g. crush injuries, reperfusion injury, compartment syndrome), actinomycosis only when refractory to antibiotics and surgical treatment, diabetic wounds of the lower extremities with a wound classification as Wagner Grade III or higher, idiopathic sudden sensorineural hearing loss, central retinal artery obstruction, delayed radiation injuries (soft tissue and bony necrosis), acute thermal burns (deep partial thickness (second degree) and full thickness burns (third degree), intracranial abscess, and acute frost bite includes systematic reviews, randomized controlled trials (RCTs) and/or recommendations from the Undersea and Hyperbaric Medical Society (UHMS). Relevant outcomes include overall survival, symptoms, changes in disease status, and functional outcomes. For all of the above indications, evidence and/or UHMS guidelines support use of HBOT. The evidence is sufficient to determine that hyperbaric oxygen therapy (HBOT) results in a meaningful improvement in net health outcomes.
The evidence of the use of systemic HBOT in individuals with any condition other than those specified in the previous paragraph includes systematic reviews and limited RCTs with small patient populations depending on the medical condition. The available studies do not demonstrate that HBOT improves relevant outcomes. Larger well-conducted RCTs reporting longer term outcomes are needed. There is insufficient evidence in the medical literature establishing that systemic HBOT is more effective than conventional therapies and is insufficient in determining the effects on net health outcomes.
Topical Hyperbaric Therapy
Topical oxygen ation, also referred to as topical hyperbaric oxygenation, is a technique of delivering 100% oxygen directly to an open, moist wound at a pressure slightly higher than atmospheric pressure. The theory behind this therapy is that the high concentrations of oxygen diffuse directly into the wound to increase the local cellular tension, which in turn promotes wound healing. During topical oxygenation a device surrounds the wound area (usually an extremity) and oxygen is delivered under pressure from a source such as a conventional oxygen tank. This therapy has been promoted as a treatment for diabetic and venous stasis ulcers, infected wounds, gangrenous lesion, decubitus ulcers, amputations, skin graft, burns or frostbite. Topical oxygenation may be performed in the inpatient, home, clinic and office setting. Typically, therapy is offered for 90 minutes per day for four consecutive days. After a three-day break, the cycle may be repeated.
According to the Undersea and Hyperbaric Medical Society (UHMS), they do not recommend the application of topical oxygen outside the structure of a clinical trial because its use in wound healing has yet to be adequately supported by scientific data.
Based on review of the available published literature, there is minimal and insufficient data to conclude that the use of topical oxygenation results in improved net health outcomes.

- Decompression illness
- Diabetic foot ulcer
- Necrotizing soft tissue infections
- Soft tissue radionecrosis
If sufficient data demonstrates that hyperbaric oxygen therapy is associated with a favorable risk-benefit ratio for an indication, which is not currently on the approved list from the Centers of Medicare and Medicaid, The Undersea and Hyperbaric Medical Society or a Commercial Insurance Carrier, the ACHM will endorse the application of hyperbaric therapy for the supported indication. Indications that meet these criteria and are supported by the ACHM as appropriate for hyperbaric oxygen therapy include:
- Acute thermal burns
- Acute central retinal artery occlusion
- Acute frost bite
- Actinomycosis (only as an adjunct to conventional therapy when the disease process is refractory to antibiotics and surgical treatment)
- Brown recluse spider bites
- Intracranial brain abscess
The ACHM supports the treatment of patients with non-approved indications only in a research setting using a protocol that has been approved by an Institutional Review Board. The ACHM supports the continued performance of well-designed clinical trials in these areas, especially those that are prospective, randomized, controlled trials. The ACHM does not support the treatment of non-approved conditions for financial gain, without investigational treatment protocols. College members who intentionally mislead the patient or family into believing that hyperbaric therapy is an approved indication or is supported by peer reviewed literate will be dismissed by the College.
American Academy of Otolaryngology-Head and Neck Surgery
In 2012, the American Academy of Otolaryngology – Head and Neck Surgery published a clinical guideline on treatment of sudden hearing loss. The guideline includes a statement that HBOT may be considered a treatment option for patients who present within 3 months of a diagnosis of ISSNHL. The document states, “Although HBOT is not widely available in the United States and is not recognized by many U.S. clinicians as an intervention for ISSNHL, the panel felt that the level of evidence for hearing improvement, albeit modest and imprecise, was sufficient to promote greater awareness of HBOT as an intervention for this condition.”
Society for Vascular Surgery in Collaboration with the American Podiatric Medical Association and the Society for Vascular Medicine
In 2016, the Society for Vascular Surgery in Collaboration with the American Podiatric Medical Association and the Society for Vascular Medicine issued a clinical practice guideline for the management of diabetic foot. The guideline includes the following: “For diabetic foot ulcers (DFUs) that fail to demonstrate improvement (>50% wound area reduction) after a minimum of 4 weeks of standard wound therapy, the committee recommends adjunctive wound therapy options. These include negative pressure therapy, biologics (platelet-derived growth factor, living cellular therapy, extracellular matrix products, amniotic membrane products), and hyperbaric oxygen therapy. Choice of adjuvant therapy is based on clinical findings, availability of therapy, and cost-effectiveness; there is no recommendation on ordering of therapy choice. Re-evaluation of vascular status, infection control, and off-loading is recommended to ensure optimization before initiation of adjunctive wound therapy.” (Grade 1B)
The guideline also states: “In patients with diabetic foot ulcer (DFU) who have adequate perfusion that fails to respond to 4 to 6 weeks of conservative management, the committee suggests hyperbaric oxygen therapy.” (Grade 2B)
Systemic hyperbaric oxygen therapy (HBOT) may be considered medically necessary in the treatment of the following conditions:
- Decompression sickness
- Acute carbon monoxide poisoning
- Gas gangrene (i.e., clostridial myositis and myonecrosis)
- Osteomyelitis, refractory to conventional medical and surgical management
- Compromised skin grafts or flaps
- Prophylactic pre-operative and post-operative treatment for patients undergoing dental surgery (non-implant-related) of an irradiated jaw
- Chronic non-healing wounds
- Profound/severe anemia with exceptional blood loss: only when blood transfusion is impossible or must be delayed
- Acute cyanide poisoning
- Air or gas embolism
- Progressive necrotizing infections (necrotizing fascitis)
- Acute peripheral arterial insufficiency
- Acute traumatic ischemia e.g.crush injuries, reperfusion injury, compartment syndrome
- Actinomycosis, only when refractory to antibiotics and surgical treatment
- Diabetic wounds of the lower extremities meeting all of the following criteria:
- Type I or II diabetes mellitus
- Wound classification as Wagner grade III or higher
- History of failed standard wound therapy as defined below
- Initiation of HBO: Covered as adjunct therapy when at least 30 consecutive days of standard wound therapy alone has produced no measureable signs of healing. HBO therapy must be used in addition to standard diabetic wound care measures such as: assessment of vascular status; correction of vascular problems in the affected limb if possible; optimization of nutritional status; optimization of glucose control; debridement by means to remove devitalized tissue; maintenance of a clean moist bed of granuation tissue with appropriate moist dressings; appropriate off loading; and necessary treatment to resolve any infection that might be present.
- Continued HBO: If measurable signs of wound healing are evident after a 30 day period of treatment with HBO therapy and standard wound therapy. If no measurable signs of wound healing are evidenced after the 30 day period, continued treatment with HBO therapy is considered not medically necessary and, therefore, not covered.
- Idiopathic sudden sensorineural hearing loss (defined as a hearing loss of at least 30dB occurring within 3 days over at least 3 contiguous frequencies) and when treatment is initiated within 14 days of symptom onset
- Central retinal artery obstruction when treatment is initiated within 24 hours of vision loss

- Acute thermal burns, deep second degree or third degree in nature
- Intracranial abscess (i.e. ceregral abscess, subdural empyma, and epidural empyma)
- Acute frost bite

Based on the peer review medical literature the available studies are limited and do not demonstrate that systemic hyperbaric oxygen therapy improves relevant outcomes. Larger well controlled RCTs reporting long term outcomes are needed. There is insufficient evidence determining the effects on net health outcomes and that systemic hyperbaric oxygen therapy is more effective than conventional therapies for all other indications not listed in the coverage criteria above.
Topical Hyperbaric Oxygen Therapy
Topical hyperbaric oxygen therapy is considered investigational for all indications.
The use of topical hyperbaric oxygen cannot be recommended outside of a clinical trial setting based on the volume and quality of supporting evidence available for any indication. The evidence is insufficient to determine the effects of this technology on health outcomes and additional clinical trials are needed. Therefore topical hyperbaric oxygen therapy is considered investigational for all indications.
WAGNER GRADE WOUND CLASSIFICATION
The Wagner classification system is used to assess wound parameters in individuals with diabetes, including the depth of penetration, the presence of osteomyelitis or gangrene, and the extent of tissue necrosis. The wound grades are defined as follows:
Grade 0 - No open lesion
Grade I - Superficial ulcer, not involving subcutaneous tissue
Grade II - Deep ulcer with penetration through the subcutaneous tissue potentially exposing tendon, bone, or joint capsule
Grade III - Deep ulcer penetrates deeper than Grade II and has evidence of abscess (pus) or osteomyelitis (bone infection)
Grade IV - Gangrene present in the toe(s)
Grade V - Gangrene of the foot requiring amputation
Thermal Burn: The depth of the burn injury is related to contact temperature, duration of contact of the external heat source, and the thickness of the skin. Because the thermal conductivity of skin is low, most thermal burns involve the epidermis and part of the dermis. The most common thermal burns are associated with flames, hot liquid, hot solid objects and steam. The depth of the burn largely determines the healing potential and the need for surgical grafting.
The traditional classification of burns as first, second, third degree was replaced by a system reflecting the need for surgical intervention. The term term fourth degree is still used to describe the most severe burns. The current designations of burn depth are classified as the following:
- Superficial or epidermal (first degree): superficial or epidermal burns involve only the epidermal layer of skin.
- Partial thickness (second degree): partial thickness burns involve the epidermis and portions of the dermis. They are characterized as either superficial or deep.
- Superficial: These burns characteristically form blisters within 24 hours between the epidermis and dermis.
- Deep: These burns extend into the deeper dermis and are characteristically different from superficial partial thickness burns. Deep burns damage hair follicles and glandular tissue.
- Full thickness (third degree): these burns extend through and destroy all layers of the dermis and often injure the underlying subcutaneous tissues.
- Fourth degree are deep and potentially life threatening injuries that extend through the skin into underlying tissues such as the fascia, muscle and/or bone.
