HCPCS code G0277: Hyperbaric Oxygen Therapy (HBO)

No. G0277 is specifically for hyperbaric oxygen therapy in a full-body chamber. It does not cover topical oxygen delivery systems.

The most frequent reasons for denials are a lack of documented medical necessity, insufficient records to support that standard wound care failed, or a diagnosis that is not covered by the payer's policy.

G0277 is primarily used by hospital outpatient departments.
