What G0237 covers

G0237 describes direct, one-on-one therapeutic work aimed at improving respiratory muscle strength or endurance. A respiratory therapist or other qualified practitioner may guide the patient through targeted breathing or muscle-training exercises in an outpatient setting, including during pulmonary rehabilitation. The service is distinct from general respiratory-function activities that do not focus on strengthening or increasing endurance of the respiratory muscles.

Report the service in 15-minute units, supported by documentation of the treatment provided, face-to-face one-on-one time, and the respiratory muscle goal addressed. The record should distinguish this focused training from other respiratory procedures furnished during the visit. CMS classifies G0237 as an incident-to service: it may be billed only when performed under physician supervision. The CMS fee schedule assigns practice-expense and malpractice relative value units, with no physician work relative value units.

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.

G0237 billing questions

When should G0237 be selected instead of G0238?

Use G0237 for one-on-one treatment directed at increasing respiratory muscle strength or endurance. G0238 describes other individual respiratory procedures, rather than this specific training focus.

How is the service counted?

G0237 is reported in 15-minute units of one-on-one face-to-face treatment. Document the time and the respiratory muscle training performed.

Can a respiratory therapist perform the service?

A respiratory therapist may provide the treatment, but G0237 is billable only when performed under physician supervision as an incident-to service.

How does G0237 differ from group respiratory therapy?

G0237 is for one patient receiving individual respiratory muscle training. G0239 describes respiratory procedures furnished to a group of two or more individuals.

What documentation supports G0237?

Document the respiratory muscle strength or endurance goal, the specific training delivered, the one-on-one face-to-face service, and the time supporting the units billed.

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.
