About 44661: Bowel-bladder fistula repair with resection
Reports operative repair of a bowel-to-bladder fistula when the surgeon resects involved intestine, bladder tissue, or both as part of treatment.
This service treats an abnormal connection between the intestine and bladder when repair requires removal of involved bowel or bladder tissue. A colorectal or general surgeon commonly performs the intestinal portion, sometimes with a urologist participating in bladder repair. Typical cases include a colovesical fistula associated with diverticular disease, inflammatory bowel disease, or a tumor. The operation may involve separating the organs, removing the diseased segment, and repairing the remaining tissue.
Select this code when the operative report documents fistula repair with resection of intestine, bladder, or both; use the non-resection sibling when repair is completed without either resection. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. 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.

44661 billing questions
How does 44661 differ from 44660?
Use 44661 when the fistula repair includes resection of involved intestine, bladder tissue, or both. Use 44660 when the repair is performed without either resection.
Can the bowel or bladder resection be billed separately?
The resection that is part of the fistula repair is included in the service represented by 44661. Do not separately report that same resection as an independent procedure.
What should the operative report document?
Document the bowel-to-bladder connection, the repair performed, and whether intestine, bladder tissue, or both were resected. The report should make clear that resection was part of treating the fistula.
Should modifier 50 be used?
No. Modifier 50 is inappropriate for this repair; the anatomy is not reported as a bilateral service.
How are other procedures in the same session paid?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. The 90-day global period includes related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
