CPT® Code 44128

Add-On Code

Enterectomy, resection of small intestine for congenital atresia, single resection and anastomosis of proximal segment of intestine; each additional resection and anastomosis (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 44128 involves an enterectomy, which is a surgical resection of the small intestine specifically performed for congenital atresia. Congenital atresia is a birth defect characterized by a complete obstruction of the small intestine, leading to the dilation of the intestinal segment that is proximal to the obstruction site. This condition can also result in the dilation of the stomach and hypertrophy of the pylorus, which may become distended. During the procedure, the surgeon makes a midline incision to access the abdominal cavity, allowing for the inspection of the abdominal organs, including the liver and gallbladder. The surgeon identifies the dilated section of the small intestine, carefully dissects it from surrounding tissues, and manages blood vessels by clamping and ligating them as necessary. The affected segment of the small intestine is then excised, and the remaining proximal and distal segments are reconnected through anastomosis. This connection may involve creating a diamond-shaped anastomosis to accommodate the differences in the size and shape of the intestinal segments. CPT® Code 44128 is specifically used to report each additional resection and anastomosis beyond the primary procedure, which is coded separately using CPT® Codes 44126 or 44127, depending on the specific technique employed for the anastomosis.
