Use the Correct Diagnosis Codes and Revenue Codes to Get Paid for PAD Rehab
The initial treatment in rehabilitation for patients suffering from Intermittent Claudication (IC) is Supervised Exercise Therapy (SET) for Symptomatic Peripheral Artery Disease (PAD). Rehabilitation using SET involves the use of intermittent walking exercise, which alternates periods of walking to moderate-to-maximum claudication, with rest.
