Hyperbaric Oxygen Therapy
Policy Number: MP-060
Latest Review Date: September 2024
Category: Medical
POLICY:
Effective for dates of service on and after November 16, 2024:
TOPICAL hyperbaric oxygen is considered investigational.
Hyperbaric oxygen therapy may be considered medically necessary when used to treat the following diagnoses:
Diagnosis |
Sessions Allowed (120 minutes per session= code billed 4 times per session. ) |
Air or gas embolism |
No more than 10 sessions should be needed to treat. |
Carbon monoxide poisoning |
In patients with persistent neurologic dysfunction after the initial treatment, subsequent treatments may be performed within 6-8 hours and continued once or twice daily until there is no further improvement in cognitive functioning. No more than 5 sessions should be needed to treat. |
Central retinal artery occlusion |
HBO must be initiated within 24 hours after initial visual loss. No more than 1 session should be needed to treat. |
Clostridial myositis and Myonecrosis (Gas Gangrene) |
The decision to terminate treatment depends upon the patient’s response to HBO2 therapy. If the patient remains toxic, the treatment needs to be extended. No more than 10 sessions should be needed to treat. |
Crush |
Treatment sessions recommended as TID for 2 days, BID for 2 days, and daily for 2 days. No more than 12 sessions should be needed to treat. |
Other acute traumatic peripheral ischemias (ATPI) |
Treatment same as for crush injuries. No more than 12 sessions should be needed to treat. |
Compartment syndromes |
No more than 3 sessions should be needed to treat. |
Cyanide poisoning, acute |
In patients with persistent neurologic dysfunction after the initial treatment, subsequent treatments may be performed within 6-8 hours and continued once or twice daily until there is no further improvement in cognitive functioning. No more than 5 sessions should be needed to treat. |
Decompression sickness |
The number of treatments required will depend upon (1) the clinical severity of the illness; (2) the clinical response to treatment; and (3) residual symptoms after the initial recompression. Depending on the patient’s initial response, there may be repetitive treatments. Patients should be treated until clinical examination reveals no further improvement in response to the HBO2 treatments. The need for follow up should be supported by documentation of the clinical evaluation before and after each treatment. No more than 10 sessions should be needed to treat. |
Enhancement of healing in problem/refractory wounds; diabetic wounds, venous stasis ulcers, decubitus ulcers, and arterial insufficiency ulcers |
The initial treatment schedule is dictated by the severity of the disease process. In the presence of limb-threatening infection after debridement or compromised surgical flaps following amputation, the patient should be treated twice daily. When the infection is under control and the soft tissue envelope improves, once daily treatments are adequate. When the suture line of the compromised surgical flap appears stable, daily treatment can be initiated. No more than 30 sessions prior to surgical grafting and not more than 10 sessions post-grafting should be needed to treat. |
Exceptional blood loss anemia |
HBO2 can be used to treat a patient with severe anemia that cannot receive blood products for medical or religious reasons when the following criteria are met: (1) mean blood pressure below 60mmHg, or requirement for vasopressors; (2) altered mental status; (3) myocardial ischemia by clinical or electrocardiogram criteria; (4) ischemic bowel; or (5) severe lactic acidosis. The vital capacity should be monitored to assess the extent of pulmonary oxygen toxicity. HBO2 should be discontinued when the red blood cells have been replaced and the signs and symptoms of tissue hypoxia have been alleviated (approximate hemoglobin of 6-8 g/dl). Up to 10 treatments may be recommended. No more than 30 treatments should be needed. |
Intracranial abscess |
HBO2 treatment is administered from 60 to 90 minutes per treatment. HBO2 treatment may be one or two sessions per day depending on the condition of the individual patient. No more than 20 treatments should be needed to treat. |
Necrotizing soft tissue infections (i.e. crepitant anaerobic cellulitis, progressive bacterial gangrene, necrotizing fasciitis, Fournier’s gangrene, non-clostridial myonecrosis synergistic necrotizing cellulitis, brown recluse spider bites) |
In the initial phase, they should be given twice daily. Once the patient’s condition has stabilized, treatments may be given on a daily basis until the infection is controlled. Because of the nature and general progression of these diseases, and because patient response is often slow, an extended course of HBO2 therapy may be necessary. No more than 30 treatments should be needed. |
Refractory osteomyelitis |
The initial treatment depends on the severity of the patient’s clinical disease. The HBO2 treatments last for 90-120 minutes. Following major debridement surgery, the patients should be treated daily if possible. No more than 40 treatments should be needed. |
Radiation injury, Delayed (soft tissue and bony necrosis); i.e. mandibular necrosis, laryngeal necrosis and soft tissue necrosis of head and neck, chest wall necrosis, radiation cystitis, radiation proctitis and enteritis, other radiation-induced abdominal and pelvic injuries, radiation injuries of the extremities, radiation injuries of the central nervous system. |
No more than 60 treatments should be needed. |
Skin grafts and flaps, Compromised |
Hyperbaric oxygen therapy is neither necessary nor recommended for the support of normal, uncompromised skin grafts or flaps. However, in tissue compromised by irradiation or in cases where there is decreased perfusion or hypoxia, HBO2 has been shown to be extremely useful in flap salvage. HBO2 can help maximize the viability of the compromised tissue, reducing the need for re-grafting or repeat flap procedures. The treatments are from 90-120 minutes. Initial treatment should be twice daily. Once the graft or flap appears more viable and stable, once-a-day treatments may suffice. No more than 20 treatments pre-graft and additional 20 treatments post-graft should be needed. |
Idiopathic sudden sensorineural hearing loss (SSNHL) |
When hyperbaric oxygen therapy (HBOT) is combined with steroid therapy within 2 weeks of onset of SSNHL or hyperbaric oxygen therapy (HBOT) is combined with steroid therapy as salvage within 1 month of onset of SSNHL. No more than 20 sessions should be needed. |
Thermal burns-Burns must be deep second degree or third degree in nature. |
Treatment is begun as soon as possible after injury, often during initial resuscitation. Three treatments should be done within the first 24 hours and twice daily afterwards. In burns of 40% or greater, treatment is rendered for 10-14 days. Many partial thickness burns will heal without surgery during this time frame and obviate the need for grafting. Treatment beyond 20-30 sessions is usually utilized to ensure graft take. While there is no absolute limit to the number of HBO2 treatments, rarely would more than 50 treatments be needed. |
Prevention of osteoradionecrosis in patients with head and neck cancer receiving periodontal dental care. |
No more than 30 treatments prior to extraction and no more than 10 treatments after extraction. |

Contraindications to HBO2
Relative Contraindications—these conditions may place patients at higher risk during HBO2 therapy:
Upper respiratory infection |
Can preclude clearing of the eustachian tubes and equalizing of internal and external pressure. Tympanostomy pressure-equalizer (PE) tubes may be inserted or myringotomy performed prior to initiation of HBO2 |
Otitis Media is a relative contraindication unless PE tubes have been inserted |
|
Hypertension |
HBO2 therapy causes vasoconstriction and can result in hypertensive crisis unless well controlled by medication |
Graves’ disease or any thyroid disorder being treated with thyroid hormone |
These disorders increase the metabolic, which in conjunction with HBO2 therapy may cause oxygen toxicity. An adjustment in the dosage may be necessary |
Seizure disorders |
HBO2 can disrupt the hemoglobin-oxygen buffering mechanism by which oxidizing free radicals are removed from tissue. This can result in the oxidation of polyunsaturated fatty acids that are normally present in cells. Because the central nervous system has high lipid content, it is highly vulnerable. The resulting CNS oxygen toxicity lowers the seizure threshold in patients with seizure disorders. |
Diabetes Mellitus Types 1 and 2 |
HBO2 has been shown to lower blood glucose levels. |
Menstruation |
There is a great risk for decompression illness in the early phase of the menstrual cycle. |
Eye pathology |
Any optic nerve or retinal disorder necessitates an evaluation by an ophthalmologist. |
Pregnancy |
There is a small risk to the fetus that high oxygen levels will stimulate the muscles around the ductus arteriosus to contract, closing it and causing fetal death. Treatments should last no longer than 120 minutes. |
Infants |
In premature infants, high oxygen levels can be toxic to the eye vasculature and can worsen bronchopulmonary dysplasia. Retrolental fibroplasia is a prominent risk factor in neonates |
Absolute Contraindications---these conditions absolutely contraindicate the administration of HBO2:
- Some types of congenital heart disease. Any cardiac anomaly that results in restriction of right ventricular outflow to the lungs might require the ductus arteriosus to remain patent for the patients to survive. HBO2 promotes the closure of the ductus arteriosus.
- Obstructed airway or restrictive airway disease can cause local trapping of air during HBO2 decompression. The expanding gas can lead to alveolar rupture. In patients with emphysema with carbon dioxide retention, the retention of CO2 also causes respiratory acidosis and cerebral edema, which can lead to respiratory depression, hypoxia, and death.
- Recent thoracic surgery if the patient does not have a chest tube. Air trapped in the thorax can expand during HBO2 and result in pneumothorax.
- Untreated pneumothorax can become a tension pneumothorax during HBO2.
- Unstable seizure disorders. If a patient has a seizure inside a monoplace chamber, immediate care cannot be provided. Unstable seizure disorder is not an absolute contraindication in a multiplace chamber.
- Pregnancy. Treatments of longer than 120 minutes are an absolute contraindication (see above).
- Infancy. If the infant has a congenital heart defect dependent on a patent ductus arterious for survival.

DESCRIPTION OF PROCEDURE OR SERVICE:
Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen at pressures between 1.5 and 3.0 atmospheres. It is generally applied systemically with the patient inside a hyperbaric chamber. HBOT can also be applied topically; ie, the body part to be treated is isolated (eg, in an inflatable bag and exposed to pure oxygen). HBOT has been investigated for various conditions that have potential to respond to increased oxygen delivery to tissue.
Hyperbaric oxygen therapy (HBOT is a technique for delivering higher pressures of oxygen to tissue. Two methods of administration are available: topical and systemic.
Topical HBOT
Topical hyperbaric oxygen therapy is a technique of delivering 100% oxygen directly to an open, moist wound at a pressure slightly higher than atmospheric pressure. It is hypothesized that the high concentrations of oxygen diffuse directly into the wound to increase the local cellular oxygen tension, which in turn promotes wound healing. Topical hyperbaric oxygen devices consist of an appliance to enclose the wound area (frequently an extremity) and a source of oxygen; conventional oxygen tanks may be used. The appliances may be disposable and may be used without supervision in the home by well-trained patients. Topical hyperbaric oxygen therapy has been investigated as a treatment of skin ulcerations resulting from diabetes, venous stasis, postsurgical infection, gangrenous lesion, decubitus ulcers, amputations, skin graft, burns, or frostbite.
Systemic HBOT
In systemic or large chamber hyperbaric oxygen, the patient is entirely enclosed in a pressure chamber and breathes oxygen at a pressure greater than one atmosphere (atm, the pressure of oxygen at sea level). Thus, this technique relies on systemic circulation to deliver highly oxygenated blood to the target site, typically a wound. In addition, systemic hyperbaric oxygen therapy can be used to treat systemic illness, such as air or gas embolism, carbon monoxide poisoning, or clostridial gas gangrene. Treatment may be carried out either in a monoplace chamber pressurized with pure oxygen or in a larger, multiplace chamber pressurized with compressed air, in which case the patient receives pure oxygen by mask, head tent, or endotracheal tube.
Adverse Events
HBOT is a generally safe therapy, with an estimated adverse side effect rate of 0.4%. Adverse events may occur either from pressure effects or the oxygen. The pressure effect (barotrauma) may affect any closed air-filled cavity such as ears, sinus, teeth, and lungs. Pain and/or swelling may occur at these sites as pressure increases during the procedure, and decreases as the procedure is ending. Oxygen toxicity may affect the pulmonary, neurologic, or ophthalmologic systems. Pulmonary symptoms include a mild cough, substernal burning, and dyspnea. Neurologic effects include tunnel vision, tinnitus, nausea, and dizziness. Ophthalmologic effects include retinopathy in neonates, cataract formation, and transient myopic vision changes.
Note that this evidence review does not address topical oxygen therapy in the absence of pressurization.
KEY POINTS:
The most recent literature review is through June 7, 2024.
Summary of Evidence
For individuals with wounds, burns or infections who receive topical hyperbaric oxygen therapy (HBOT), the evidence includes a systematic review, case series, and a randomized controlled trial (RCT). Relevant outcomes are overall survival (OS), symptoms, change in disease status, and functional outcomes. The systematic review identified 3 RCTs including patients with sacral pressure ulcers, ischial pressure ulcers, and refractory venous ulcers. All trials reported that healing improved significantly after HBOT than after standard of care. Pooling of results was not possible due to heterogeneity in patient populations and treatment regimens. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with chronic diabetic ulcers who receive systemic HBOT, the evidence includes RCTs and systematic reviews. Relevant outcomes are symptoms and change in disease status. Meta-analyses of RCTs found significantly higher diabetic ulcer healing rates with HBOT than with control conditions. Two of the 3 meta-analyses found that HBOT was associated with a significantly lower rate of major amputation. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with carbon monoxide poisoning who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are OS and symptoms. A meta-analysis in a Cochrane review of low-quality RCT data did not find HBOT to be associated with a significantly lower risk of neurologic deficits after carbon monoxide poisoning. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with radionecrosis, osteoradionecrosis, or treatment of irradiated jaw who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are symptoms and change in disease status. A meta-analysis in a Cochrane review of RCTs found evidence that HBOT improved radionecrosis and osteoradionecrosis outcomes and resulted in better outcomes before tooth extraction in an irradiated jaw. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with chronic refractory osteomyelitis who receive systemic HBOT, the evidence includes case series. Relevant outcomes are symptoms and change in disease status. The case series reported high rates of successful outcomes (no drainage, pain, tenderness, or cellulitis) in patients with chronic refractory osteomyelitis treated with HBOT. However, controlled studies are needed to determine conclusively the impact of HBOT on health outcomes compared with other interventions. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with acute thermal burns who receive systemic HBOT, the evidence includes a systematic review of 2 RCTs. Relevant outcomes are OS, symptoms, and change in disease status. Both RCTs were judged to have poor methodologic quality. Evidence from well-conducted controlled trials is needed. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with acute surgical and traumatic wounds who receive systemic HBOT, the evidence includes RCTs, controlled nonrandomized studies, and systematic reviews. Relevant outcomes are OS, symptoms, change in disease status, and functional outcomes. There was considerable heterogeneity across the 4 RCTs identified (eg, patient population, comparison group, treatment regimen, outcomes). This heterogeneity prevented pooling of trial findings and limits the ability to definitively conclude the impact of HBOT on health outcomes for patients with acute surgical and traumatic wounds. Additional evidence from high-quality RCTs is needed. A systematic review of controlled Chinese studies suggests HBOT may increase the survival rate of compromised skin grafts and flaps when initiated within 72 hours; however, risk of bias in the original Chinese publications cannot be evaluated. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with bisphosphonate-related osteonecrosis of the jaw who receive systemic HBOT, the evidence includes an RCT. Relevant outcomes are symptoms and change in disease status. The RCT was unblinded and reported initial benefits at 3-month follow-up; however, there were no significant benefits of HBOT for most health outcomes compared with standard care in the long-term (6 months to 2 years).The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with necrotizing soft tissue infections who receive systemic HBOT, the evidence includes systematic reviews. Relevant outcomes are OS, symptoms, and change in disease status. A Cochrane review did not identify any RCTs. Another systematic review of retrospective cohort studies with methodological limitations did not find consistent benefit of adjunctive HBOT use. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with acute coronary syndrome who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are OS, symptoms, change in disease status, and functional outcomes. A Cochrane review identified 6 RCTs. There were 2 pooled analyses, 1 found significantly lower rates of death with HBOT and the other reported inconsistent results in left ventricular function. Additional RCT data are needed. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with acute ischemic stroke who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are OS, symptoms, change in disease status, and functional outcomes. Cochrane reviewers could only pool data for a single outcome (mortality at 3 to 6 months), and for that outcome, there was no significant difference between active and sham HBOT treatments. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with motor dysfunction associated with stroke who receive systemic HBOT, the evidence includes an RCT. Relevant outcomes are symptoms and functional outcomes. The RCT, which used a crossover design, found better outcomes with HBOT at 2 months than with delayed treatment. However, the trial had a number of methodologic limitations (eg, lack of patient blinding, heterogeneous population, high dropout rate) that make it difficult to evaluate the efficacy of HBOT. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with Bell palsy who receive systemic HBOT, the evidence includes a systematic review. Relevant outcomes are symptoms, change in disease status, and functional outcomes. A Cochrane review did not identify any RCTs meeting selection criteria; the single RCT found did not have a blinded outcome assessment. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with traumatic brain injury who receive systemic HBOT, the evidence includes RCTs and systematic reviews. Relevant outcomes are OS, symptoms, change in disease status, and functional outcomes. RCTs were heterogeneous regarding intervention protocols, patient populations, and outcomes reported. Systematic reviews conducted pooled analyses only on a minority of the published RCTs, and these findings were inconsistent. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with inflammatory bowel disease who receive systemic HBOT, the evidence includes a RCTs, observational studies, and a systematic review. Relevant outcomes are symptoms, change in disease status and functional outcomes. Three RCTs have reported mixed findings in patients with ulcerative colitis, with one study terminated early due to futility. A systematic review including the RCT and observational studies found a high rate of bias in the literature due to attrition and reporting bias. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with idiopathic sudden sensorineural hearing loss who receive systemic HBOT, the evidence includes systematic reviews. Relevant outcomes are symptoms, change in disease status, and functional outcomes. A Cochrane review of RCTs had mixed findings from studies that included individuals with tinnitus. Some outcomes (ie, improvement in hearing of all frequencies, >25% return of hearing) were better with HBOT than with a control intervention, but more than 50% return of hearing did not differ significantly between groups. There was important variability in the patients enrolled in the studies. A subsequent systematic review had similarly limited conclusions due to the inclusion of non-randomized studies. A third review found a higher proportion of patients with hearing recovery with HBOT compared to medical treatment alone, but the analysis was limited to 2 RCTs with methodological limitations. One RCT published subsequent to the systematic reviews found a positive effect of HBOT plus steroid combination therapy on measures of auditory function compared to either HBOT or steroids alone, but other outcomes were not reported and the study had numerous relevance, design, and conduct limitations. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with delayed-onset muscle soreness who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are symptoms and functional outcomes. A Cochrane review of RCTs found worse short-term pain outcomes with HBOT than with control and no difference in longer-term pain or other outcomes (eg, swelling). The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with autism spectrum disorder who receive systemic HBOT, the evidence includes an RCT and a systematic review. Relevant outcomes are symptoms and functional outcomes. A Cochrane review identified a single RCT on HBOT for autism spectrum disorder and this trial did not find significantly better parental-assessed or clinician-assessed outcomes with HBOT compared with sham. A subsequent controlled trial reached the same conclusion. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with cerebral palsy who receive systemic HBOT, the evidence includes 2 RCTs and an observational study. Relevant outcomes are symptoms and functional outcomes. One RCT was stopped early due to futility, and the other did not find significantly better outcomes with HBOT than with a sham intervention. The observational study focused on sleep disorders in children with cerebral palsy and reported improvements with the HBOT treatment. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with vascular dementia who receive systemic HBOT, the evidence includes an RCT and a systematic review. Relevant outcomes are symptoms and functional outcomes. The Cochrane review identified only a single RCT with methodologic limitations. Well-conducted controlled trials are needed. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with radiotherapy adverse events who receive systemic HBOT, the evidence includes RCTs, nonrandomized comparator trials, case series, and systematic reviews. Relevant outcomes are symptoms and functional outcomes. Two systematic reviews included few RCTs and provide limited evidence on the effect of HBOT. Two RCTs had inconsistent findings. One reported no short-term benefit with HBOT, but some benefits 12 months after radiotherapy; the other did not find a significant benefit of HBOT at 12-month follow-up. Another RCT assessed HBOT for radiation-induced cystitis and found significant benefit by some measures but not others. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with idiopathic femoral neck necrosis who receive systemic HBOT, the evidence includes an RCT. Relevant outcomes are symptoms, change in disease status, and functional outcomes. The RCT, which had a small sample, only reported short-term (ie, 6-week) outcomes. Larger well-conducted RCTs reporting longer-term outcomes are needed. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with a migraine who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are symptoms, change in disease status, and functional outcomes. The Cochrane review conducted a pooled analysis including 3 of the 11 trials. Meta-analysis of these 3 RCTs found significantly greater relief of migraine symptoms with HBOT than with a comparator intervention within 45 minutes of treatment. Longer-term data are needed. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with herpes zoster who receive systemic HBOT, the evidence includes an RCT. Relevant outcomes are symptoms and change in disease status. The RCT was unblinded and only reported short-term (ie, 6-week) outcomes. Additional well-conducted RCTs with longer follow-up are needed. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with fibromyalgia who receive systemic HBOT, the evidence includes RCTs. Relevant outcomes are symptoms, change in disease status, and functional outcomes. Only 2 RCTs were identified, and both reported positive effects of HBOT on tender points and pain. However, the trials had relatively small samples and methodologic limitations (eg, quasi-randomization, no or uncertain sham control for a condition with subjective outcomes susceptible to a placebo effect). Moreover, the HBOT protocols varied. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with multiple sclerosis who receive systemic HBOT, the evidence includes RCTs and a systematic review. Relevant outcomes are symptoms and functional outcomes. A Cochrane review of RCTs did not find a significant difference in Expanded Disability Status Scale scores when patients with multiple sclerosis were treated with HBOT versus a comparator intervention. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
For individuals with cancer and are undergoing chemotherapy who receive systemic HBOT, the evidence includes an RCT and a systematic review. Relevant outcomes are OS and change in disease status. While the systematic review reported improvements in tumor control in patients with head and neck cancer who received HBOT, the adverse events accompanying the treatment (eg, radiation tissue injury, seizures) were significant. The single RCT did not find a significant difference in survival for cancer patients who received HBOT before chemotherapy compared with usual care. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
Practice Guidelines and Position Statements
American Academy of Otolaryngology - Head and Neck Surgery
In 2019, the American Academy of Otolaryngology-Head and Neck Surgery updated clinical guidelines on the treatment of sudden sensorineural hearing loss (SSNHL). They give the following options regarding HBOT:
"Clinicians may offer, or refer to a physician who can offer, hyperbaric oxygen therapy (HBOT) combined with steroid therapy within 2 weeks of onset of SSNHL."
"Clinicians may offer, or refer to a physician who can offer, hyperbaric oxygen therapy (HBOT) combined with steroid therapy as salvage within 1 months of onset of SSNHL.”
The guideline provided a comprehensive list of evidence gaps and future research needs on the use of HBOT for SSNHL. These included, among others, the need for a standardized, evidence-based definition of SSNHL, the assessment of the prevalence of SSNHL, and the need for the development of standardized HBOT treatment protocols and standardized outcome assessments.
American College of Cardiology/American Heart Association
In 2024, the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines published a Guideline for the Management of Lower Extremity PAD. The Guideline was developed in collaboration with and endorsed by the American Association of Cardiovascular and Pulmonary Rehabilitation, American Podiatric Medical Association, Association of Black Cardiologists, Society for Cardiovascular Angiography and Interventions, Society for Vascular Medicine, Society for Vascular Nursing, Society for Vascular Surgery, Society of Interventional Radiology, and Vascular & Endovascular Surgery Society.
The Guideline included the following statements relevant to this evidence review:
"Beyond wound care, hyperbaric oxygen therapy has been studied in the context of wound healing for CLTI as an adjunctive therapy to revascularization and may have a limited role in this population."
"Hyperbaric oxygen therapy may be considered as an adjunctive therapy to revascularization for wound healing in the context of CLTI (chronic limb threatening ischemia) and diabetic foot ulcers."
American College of Cardiology/American Stroke Association
In 2019 the American Heart Association and American Stroke Association updated the guidelines for early management of acute ischemic stroke. The guidelines were endorsed by the Society for Academic Emergency Medicine, the Neurocritical Care Society, the American Association of Neurological Surgeons, and the Congress of Neurological Surgeons. The Guideline included the following statements relevant to this evidence review:
"The limited data available on the utility of HBO therapy for acute ischemic stroke (not related to cerebral air embolism) show no benefit. HBO therapy is associated with claustrophobia and middle ear barotrauma, as well as an increased risk of seizures. Given the confines of HBO chambers, the ability to closely/adequately monitor patients may also be compromised. HBO thus should be offered only in the context of a clinical trial or to individuals with cerebral air embolism."
Society of Vascular Surgery et al
In 2016, the Society of Vascular Surgery in collaboration with the American Podiatric Medical Association and the Society for Vascular Medicine published guidelines on the management of the diabetic foot. According to the guidelines, for diabetic foot ulcers that fail to demonstrate improvement (>50% wound area reduction) after a minimum of 4 weeks of standard wound therapy, adjunctive therapy such as HBOT is recommended (grade 1B). Also, for diabetic foot ulcers with adequate perfusion that fail to respond to 4 to 6 weeks of conservative management, HBOT is suggested (grade 2B).
Undersea and Hyperbaric Medical Society
In 2015, the Undersea and Hyperbaric Medical Society (UHMS) published guidelines on the use of HBOT for treating diabetic foot ulcers. Recommendations in the current version include:
- Suggest against using HBOT in patients with "Wagner Grade 2 or lower diabetic foot ulcers..."
- Suggest adding HBOT in patients with "Wagner Grade 3 or higher diabetic foot ulcers that have not shown significant improvement after 30 days of [standard of care] therapy..."
- Suggest "adding acute post-operative hyperbaric oxygen therapy to the standard of care" in patients with "Wagner Grade 3 or higher diabetic foot ulcers" who have just had foot surgery related to their diabetic ulcers.
The 2023 UHMS Hyperbaric Oxygen Therapy Indications (15th edition) included the following indications as recommended:
- Air or Gas Embolism
- Arterial insufficiencies: Central Retinal Artery Occlusion; Hyerbaric oxygen Therapy for Selected Problem Wounds
- Carbon Monoxide Poisoning and carbon monoxide complicated by cyanide poisoning
- Clostridial Myonecrosis (Gas Gangrene)
- Acute Traumatic Ischemias
- Decompression Sickness
- Severe anemia
- Intracranial abscess
- Necrotizing soft tissue infections
- Refractory osteomyelitis
- Delayed radiation injury (soft tissue and bony necrosis)
- Compromised grafts and flaps
- Acute thermal burn injury
- Sudden Sensorineural hearing loss
- Avascular Necrosis (Aseptic Osteonecrosis).
U.S. Preventive Services Task Force Recommendations
HBOT is not a preventive service.
KEY WORDS:
Systemic hyperbaric oxygen, topical hyperbaric oxygen, hyperbaric oxygen, HBO, HBO2, THBO
APPROVED BY GOVERNING BODIES:
In 2013, FDA published a statement warning that non-FDA approved uses of HBOT may endanger the health of patients. If patients mistakenly believe that HBOT devices have been proven safe for uses not cleared by FDA, they may delay or forgo proven medical therapies.
As of July 2021, the FDA has cleared hyperbaric chambers for the following disorders:
- Air and gas bubbles in blood vessels
- Anemia (severe anemia when blood transfusions cannot be used)
- Burns (severe and large burns treated at a specialized burn center)
- Carbon monoxide poisoning
- Crush injury
- Decompression sickness (diving risk)
- Gas gangrene
- Hearing loss (complete hearing loss that occurs suddenly and without any known cause)
- Infection of the skin and bone (severe)
- Radiation injury
- Skin graft flap at risk of tissue death
- Vision loss (when sudden and painless in one eye due to blockage of blood flow)
- Wounds (non-healing, diabetic foot ulcers).

Available for comment October 1, 2024 through November 15, 2024.
This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.
This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.
The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.
As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.
The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:
1. The technology must have final approval from the appropriate government regulatory bodies;
2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
3. The technology must improve the net health outcome;
4. The technology must be as beneficial as any established alternatives;
5. The improvement must be attainable outside the investigational setting.
Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:
1. In accordance with generally accepted standards of medical practice; and
2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
3. Not primarily for the convenience of the patient, physician or other health care provider; and
4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
