Urology surgery
About 50830: Revision of urinary cutaneous diversion
Revision of an existing urinary diversion that drains through the skin, reported when surgery corrects a problem with the diversion or restores urine flow.
This operation revises an existing urinary diversion that carries urine to a skin opening, such as a conduit or cutaneous stoma. A urologist typically performs it in a hospital operating room when the diversion is narrowed, retracted, or otherwise malfunctioning and requires surgical correction. It is a revision, not the initial construction of a diversion.
Select the code based on the operative work on the existing cutaneous diversion. The operative report should identify the diversion, the problem addressed, and the reconstructive steps performed. CMS assigns a 90-day global period, including the day-before preoperative visit 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% multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

50830 billing questions
How is this different from a code for creating a urinary diversion?
Use 50830 for surgical revision of an existing cutaneous diversion. Codes for creating a diversion describe its initial construction, rather than correction of an existing one.
What documentation supports reporting 50830?
Document the existing cutaneous diversion, the problem prompting revision, and the operative steps used to correct it or restore urine flow.
Is modifier 50 appropriate?
No. CMS identifies the descriptor or anatomy as unsuitable for bilateral reporting, so modifier 50 is inappropriate.
How does the global period affect postoperative care?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
