What 97155 covers

This service covers face-to-face adaptive behavior treatment for one patient when a physician or other qualified health care professional evaluates the patient’s response and modifies the treatment protocol. It may include directing a technician while treatment is being delivered. These services are used in behavioral programs, including care for people with autism, in settings such as clinics or homes.

Report the service in 15-minute units. The physician fee schedule lists 97155 as carrier priced, status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. Distinguish protocol-modification treatment from technician-delivered treatment, group treatment, caregiver guidance, and assessment services in the same adaptive behavior code family.

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.
