Summary
This is a new comprehensive policy defining coverage criteria for Hyperbaric Oxygen Therapy (HBOT). Topical HBOT is considered investigational (not covered). Systemic HBOT is medically necessary for specific conditions including non-healing diabetic wounds meeting strict criteria, gas embolism, carbon monoxide poisoning, and other acute conditions, but investigational for many other uses.
Action Required
Immediately: Billing team must verify all HBOT claims meet the specific medical necessity criteria outlined in the policy. Ensure proper documentation for covered conditions (diabetic wounds Wagner grade 3+, gas embolism, carbon monoxide poisoning, etc.). Update systems to flag that topical HBOT is not covered. Verify physician attendance code 99183 is billed appropriately with all systemic HBOT treatments as required.
