CPT code 46707 represents surgical repair of an anorectal fistula using a tissue flap to close an abnormal opening between the anus and rectum. This reconstructive procedure is clinically significant because anorectal fistulas can cause persistent infection, pain, and fecal leakage, and repair often requires specialized surgical technique. Nationally, this code is used across inpatient and outpatient surgical settings for patients with fistulas from prior surgery, congenital anomalies, trauma, infection, or other etiologies.
