What G0277 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
