CPT® Code 46706

The procedure described by CPT® Code 46706 involves the repair of an anal fistula using fibrin glue, a biocompatible adhesive that promotes healing. An anal fistula is an abnormal connection between the anal canal and the skin surrounding the anus, often resulting from an infection or abscess. The procedure begins with the preparation and draping of the perineum, ensuring a sterile environment. A digital rectal exam is performed to assess the condition and locate the fistula accurately. An anoscope, a tubular instrument, is then utilized to visualize the anal canal and identify the specific site of the fistula. Following this, a probe is introduced into the internal opening of the fistula, allowing the clinician to trace the fistulous tract to its external opening. To facilitate the repair, a curette is employed to remove any granulation tissue that may obstruct the healing process within the fistula tract. Finally, a flexible catheter is inserted at the internal opening, and fibrin glue is injected to fill the entire fistulous tract, effectively sealing it and promoting closure. This minimally invasive technique aims to reduce recovery time and complications associated with traditional surgical methods for fistula repair.
