Hyperbaric therapy
About G0277: Full-body hyperbaric oxygen treatment
Reports each 30-minute unit of therapeutic oxygen delivered under pressure in a full-body chamber for a medically indicated treatment session.
G0277 reports the technical service of delivering hyperbaric oxygen in a pressurized, full-body chamber. A patient breathes oxygen while enclosed in the chamber, commonly at a hospital outpatient department or a specialized wound-care or hyperbaric center. Treatment may be part of care for selected conditions such as diabetic lower-extremity wounds or delayed radiation tissue injury. The chamber service is distinct from the physician’s attendance and supervision of the session.
Report units based on the documented treatment time, with each unit representing 30 minutes. The record should support the medical need for hyperbaric treatment, the full-body chamber service, and the time treated. CMS classifies G0277 as technical-component-only: physician interpretation is separately coded rather than included in this service. The CMS fee schedule assigns practice expense and malpractice RVUs, with no physician-work RVUs, consistent with the technical nature of the code.

G0277 billing questions
Does G0277 include the physician’s attendance and supervision?
No. G0277 reports the chamber treatment; CPT 99183 describes physician attendance and supervision of hyperbaric oxygen therapy per session.
How many units should be reported?
Report one unit for each documented 30-minute treatment interval. The record should substantiate the treatment time billed.
Does G0277 include a professional component?
No. CMS identifies G0277 as technical-component-only, with physician interpretation reported separately.
Can wound debridement be reported on the same date?
A distinct debridement service may be reported when it is performed and separately documented. G0277 represents chamber treatment, not wound debridement.
