CPT® Code 50840

The procedure described by CPT® Code 50840 involves the surgical replacement of all or part of the ureter using a segment of intestine. This is typically indicated when a section of the ureter is diseased or injured, necessitating its removal. The remaining healthy portion of the ureter is then connected to the intestine, allowing for the continuation of urinary flow. The surgery begins with an incision in the abdomen, through which the peritoneum is accessed. The small bowel is carefully isolated and moved out of the surgical area to provide a clear view of the ureter. The affected segment of the ureter is excised, and the distal end is ligated at the ureterovesical junction to prevent any leakage. A segment of the intestine, often the ileum, is selected based on the length required for the replacement. This segment is then prepared for anastomosis, which involves connecting it to both the ureter and the bladder. The procedure is intricate, requiring precise surgical techniques to ensure proper healing and function post-operation.
