CPT® Code 50800

The procedure described by CPT® Code 50800 refers to a ureteroenterostomy, which is a surgical operation that involves the direct anastomosis, or connection, of the ureter to the intestine. This procedure is typically indicated when there is a diseased or injured segment of the ureter, particularly in the middle or distal portions. During the operation, the affected segment of the ureter is surgically removed, and the healthy proximal segment is then connected to the intestine, allowing for the proper drainage of urine into the gastrointestinal tract. The surgical approach generally involves making an incision in the midline of the abdomen to access the peritoneal cavity. The small bowel is carefully isolated and moved out of the way to provide a clear view of the ureter, which is then mobilized while ensuring that the surrounding perirenal tissue and blood supply are preserved. After excising the diseased ureter segment, the remaining ureter is ligated at the ureterovesical junction. A segment of the intestine, often the ileum, is selected and prepared for the anastomosis. The ureter is then spatulated, stented, and connected to the intestine in an end-to-side manner. In some cases, a nephrostomy tube may be placed to facilitate drainage. Finally, the surgical wound is closed in layers to promote healing.
