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.
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.

G0239 billing questions
How does G0239 differ from G0238?
G0239 is for respiratory therapeutic procedures delivered to two or more patients together. G0238 is the corresponding individual, one-to-one service.
How does G0239 differ from G0237?
G0237 describes individual treatment focused on respiratory muscle strength or endurance. G0239 is the group-format code for respiratory therapeutic procedures.
How many units may be reported?
G0239 is reported in 15-minute units for the qualifying group treatment furnished to the patient. Record the time supporting the units; do not count the same minutes twice for overlapping services.
What documentation supports G0239?
Document the respiratory therapy provided, the patient’s participation, the group setting with at least two individuals, and the time spent in the service.
Can a therapist bill G0239 without physician supervision?
No. CMS identifies G0239 as an incident-to service and permits billing only when the service is performed under physician supervision.
Is G0239 the same as a pulmonary rehabilitation session code?
No. G0239 reports timed group respiratory procedures; G0424 represents pulmonary rehabilitation by the session. Select the code that matches the service furnished and documented.
