Supervised Exercise Therapy Coding Guidelines (2021)

SET involves the use of intermittent walking exercise, which alternates periods of walking to moderate-to-maximum claudication, with rest. SET has been recommended as the initial treatment for patients suffering from IC, the most common symptom experienced by people with PAD.

SET program covers Up to 36 sessions over a 12-week period if all of the following components of a SET program are met: 

The SET program must:

Consist of sessions lasting 30-60 minutes, comprising a therapeutic exercise-training program for PAD in patients with claudication.

Be conducted in a hospital outpatient setting, or a physician’s office.

Be delivered by qualified auxiliary personnel necessary to ensure benefits exceed harms, and who are trained in exercise therapy for PAD.

Be under the direct supervision of a physician, physician assistant, or nurse practitioner/clinical nurse specialist who must be trained in both basic and advanced life support techniques.
