Hyperbaric oxygen therapy (HBO) is a technique of delivering higher pressures of oxygen to the tissues. Two methods of administration are currently available:
- Systemic hyperbaric oxygen administration: Hyperbaric oxygen therapy is a treatment in which a patient breathes near 100% oxygen intermittently while inside a treatment chamber at a pressure higher than sea level pressure (i.e. >1 atmosphere absolute; atm abs). Treatment can be carried out in either a monoplace or multiplace chamber.
- Monoplace Chamber: This accommodates a single patient, the entire chamber is pressurized with near 100% oxygen and the patient breaths 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.
According to the Undersea & Hyperbaric Medical Society (UHMS) definition, breathing near 100% oxygen at 1 atmosphere of pressure or exposing isolated parts of the body to near 100% oxygen does not constitute hyperbaric oxygen therapy. The patient must receive the oxygen by inhalation within a pressurized chamber. Current information indicates that pressurization should be at 1.4 atm abs or higher.
- Topical oxygen therapy: is a technique of delivering 100% oxygen directly to an open, moist wound at a pressure slightly higher than ambient pressure. It is theorized that the high concentrations of oxygen diffuse directly into the wound to increase the local cellular oxygen tension, which in turn promotes healing. According to the Undersea and Hyperbaric Medical Society, topical oxygen should not be termed hyperbaric oxygen since doing so suggests topical oxygen treatment is equivalent or identical to hyperbaric oxygen. UHM does 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.
Examples of topical oxygen administration include a semi-rigid chamber or a polyethylene bag placed over an extremity or trunk wound and secured in place to create an airtight seal. High flow rate oxygen (10 Lpm) is directed into the chamber or bag and passes over the wound. Another device, the TransCu 02 (E02 Concepts Inc., San Antonio, TX) is an electrochemical low-dose, oxygenation system intended for use with advanced wound dressings to treat difficult to heal wounds such as venous leg ulcers, diabetic foot ulcers and pressure ulcers, according to the manufacturer's web site.

- Clostridial myositis and myonecrosis (gas gangrene)
- Crush injury, compartment syndrome and other acute traumatic ischemias
- Decompression sickness
- Arterial insufficiencies
- Cranial retinal artery occlusion
- Enhancement of healing in selected problem wounds
- Severe anemia
- Intracranial abscess
- Necrotizing soft tissue infections
- Osteomyelitis (refractory)
- Delayed radiation injury (soft tissue and bony necrosis)

American College of Hyperbaric Medicine (ACHM)
The following indications are approved by the American College of Hyperbaric Medicine and are reimbursable through CMS:
- Air or gas embolism
- Acute carbon monoxide intoxication (cyanide poisoning)
- Acute peripheral arterial insufficiency
- Chronic refractory osteomyelitis
- Clostridial myonecrosis (gas gangrene)
- Compromised skin grafts/tissue flaps
- Crush injuries
- Compartment syndrome and acute traumatic ischemias
- 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 indications or is supported by peer reviewed literate will be dismissed by the College.
Systemic hyperbaric oxygen (HBO) 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)
- 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
- 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 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 evidence 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
- Delayed radiation injuries (soft tissue and bony necrosis) (e.g. induced tissue injury, especially in gynecologic malignancies, cystitis, radiation enteritis, proctitis and osteoradionecrosis)
- Acute thermal burns: deep partial thickness (second degree) and full thickness burns (third degree)
- Intracranial abscess (i.e. ceregral abscess, subdural empyma, and epidural empyma)
- Acute frost bite
Systemic hyperbaric Oxygen Therapy (HBO) is considered investigational for all indications not listed above including, but not limited to, the following diagnoses or circumstances as there is insufficient evidence in the medical literature to establish that systemic hyperbaric oxygen therapy is more effective then conventional therapies:
- Acute cerebral edema

Topical Oxygen Therapy: According to the Undersea and Hyperbaric Medical Society, topical oxygen should not be termed hyperbaric oxygen since doing so suggests topical oxygen treatment is equivalent or identical to hyperbaric oxygen. All applications of topical oxygen therapy, including electrochemical low-dose oxygenation systems, and those described as hyperbaric are considered investigational as the application of topical oxygen therapy cannot be recommended outside of a clinical trial setting based on the volume and quality of supporting evidence available, additional clinical trials are needed. Also, there is insufficient evidence in the medical literature to establish the effectiveness in the treatment of chronic wound healing.
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.
