What G0238 covers
G0238 represents individualized respiratory therapy intended to improve respiratory function through therapeutic procedures outside the respiratory-muscle strength or endurance work assigned to G0237. A respiratory therapist or other clinical staff member typically provides the face-to-face treatment in an outpatient respiratory-care or pulmonary rehabilitation setting. The service is delivered to one patient at a time, and monitoring is included.
Report the service in 15-minute units, supported by documentation of the procedures performed and the face-to-face treatment time. The record should distinguish the work from respiratory-muscle strength or endurance training and from a group session. CMS treats G0238 as an incident-to service: it may be billed only when performed under physician supervision. Its fee schedule relative-value profile assigns no physician work RVUs; practice expense and malpractice RVUs are included.
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.
