HCPCS G0239: Respiratory therapyMedicare rate & RVUs

Medicare pays $14.36 for G0239 nationally in the office. Local office rates run $12.22–$20.41.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What G0239 covers

G0239 represents respiratory therapy provided to at least two patients in a group, with the service directed at improving respiratory function or building respiratory muscle strength and endurance. It is used in settings such as pulmonary rehabilitation, where a respiratory therapist or other qualified therapy professional leads prescribed therapeutic activity for participants together. The group format distinguishes this service from individualized respiratory procedures, even when the therapeutic goals are similar.

Report the code for each 15 minutes of qualifying group treatment furnished to the patient. Documentation should identify the respiratory intervention, the patient’s participation, the group format, and the time supporting the units billed. CMS assigns no physician work RVU; the fee schedule value reflects practice expense and malpractice components. This is an incident-to service, so it may be billed only when performed under physician supervision.
