What 50930 covers
A urologic surgeon closes an abnormal passage between a ureter and an intestinal segment. The connection can allow urine to enter the bowel or bowel contents to reach the urinary tract. The operation is performed in an operating room; other surgical specialists may participate when the bowel also requires operative management.
Choose this code when the operative report documents a ureter-to-bowel fistula and its surgical closure, rather than a ureter-to-skin fistula or repair of a ureter without a fistula. The 90-day major-surgery global includes the day-before preoperative visit and 90 days of related postoperative care. For other procedures performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate for this anatomy. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
