What 51580 covers
A urologist removes the entire bladder and routes the ureters either to the skin as a ureterostomy or into the sigmoid colon as a ureterosigmoidostomy. The operation is generally performed in a hospital operating room, commonly for bladder cancer requiring cystectomy and urinary diversion. The operative report should identify the extent of bladder removal and the specific route used for each ureter.
Choose this code for the ureterostomy or ureterosigmoidostomy approach, rather than a bowel conduit or continent reservoir. The diversion is part of the reported operative service. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

51580 billing questions
How does this differ from 51590?
This code describes diversion by ureterostomy or ureterosigmoidostomy. Choose 51590 when the surgeon creates an ileal conduit or sigmoid bladder.
Is the urinary diversion separately reported?
The ureterostomy or ureterosigmoidostomy is part of this complete cystectomy service. The documented diversion method determines whether this code or a different cystectomy-with-diversion code applies.
Should modifier 50 be appended for bilateral ureteral diversion?
No. CMS identifies bilateral adjustment as inappropriate for this code; the descriptor and anatomy do not support modifier 50.
What documentation supports code selection?
The operative report should establish complete bladder removal and specify whether the ureters were brought to the skin or implanted into the sigmoid colon.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction when performed in the same session.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
