Hyperbaric oxygen therapy for wound care

Hyperbaric oxygen (HBO) therapy provides oxygen under higher-than-atmospheric pressure to assist in the healing of wounds. This is an adjunctive therapy provided in most hospital-based outpatient departments that specialize in wound care.

Documentation for HBO includes the ascent time, descent time and pressurizing level, as well as provider attendance and supervision. In order for insurers to pay for the therapy, there generally needs to be a monthly documentation of improvement.

Medicare-approved diagnosis includes crush injuries, acute traumatic peripheral ischemia, diabetic wounds, compromised skin grafts and necrotizing infections. The code for therapy is G0277 and CPT code 99183 for physician or healthcare professional supervision.
