CPT® Code 44640

The procedure described by CPT® Code 44640 involves the surgical closure of an intestinal cutaneous fistula. An intestinal cutaneous fistula is defined as an abnormal connection or passage that forms between the intestine and the skin, which can lead to complications such as infection, fluid loss, and nutritional deficiencies. The surgical intervention is necessary to restore normal anatomy and function by eliminating this abnormal communication. During the procedure, the physician makes an incision in the abdomen to access the fistulous tract. This tract, which connects the intestine to the skin, is carefully located and severed at its opening in the intestine. The intestinal opening is then meticulously closed using sutures to prevent any further leakage of intestinal contents. Following this, the portion of the tract that lies within the abdominal wall is excised, and the abdominal wall is closed in layers to ensure proper healing and support. Finally, the surgical incision itself is closed, completing the procedure and aiming to restore the integrity of the abdominal wall and intestinal function.
