What 50920 covers
A urologist uses this service to close a ureterocutaneous fistula, an abnormal passage that allows urine to drain from a ureter through the skin. The operation addresses the communication between the ureter and the skin, rather than a planned urinary opening or a fistula connecting the ureter to bowel. It may be performed to treat persistent urinary drainage through a cutaneous tract after an injury or prior procedure.
Report the code when the operative work is closure of the ureter-to-skin fistula. The operative report should identify the fistula and describe its location and the repair performed. This major surgery has a 90-day global period, including the day before surgery and 90 days of related postoperative care. 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 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

When would 50900 be more appropriate?
Use 50900 for ureter repair when the operation is not closure of a ureter-to-skin fistula. The operative report should support the specific repair performed.
