Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who previously underwent placement of an anal seton to treat a transsphincteric or complex anal fistula. The patient presents to an outpatient colorectal or general surgery clinic for evaluation after clinical signs of fistula tract drainage have resolved and the wound has sufficiently healed. The provider documents cessation of drainage, resolution of local infection, and satisfactory maturation of the tract on examination. Consent is obtained and the patient is prepared in the clinic procedure room or ambulatory surgery center. Under local anesthesia with or without conscious sedation, the clinician carefully removes the established anal seton or other marker, inspects the external and internal openings, and provides wound care instructions. The patient is observed briefly for bleeding or pain and discharged with follow-up instructions for continued wound assessment and possible further definitive fistula surgery if indicated.
