Billing Code Overview
CPT code 44660 describes the surgical closure of an enterovesical fistula — an abnormal connection between the small intestine and the urinary bladder. The procedure is performed to eliminate the pathological passage that can cause recurrent urinary tract infections, fecaluria, urinary leakage, or other complications related to contamination between the gastrointestinal and genitourinary tracts.
Service type: Surgical procedure (open or potentially minimally invasive operative repair) performed by a general surgeon or colorectal surgeon to excise and close the fistulous tract and restore normal separation between bowel and bladder.
Typical site of service: Inpatient hospital operating room or ambulatory surgical center, depending on patient condition, complexity of the fistula, and perioperative needs.
