Urology procedure
About 50385: Transurethral ureteral stent exchange
Report this service when a urologist removes an existing ureteral stent and places a replacement through the urethra, typically using cystoscopy.
A urologist passes a cystoscope through the urethra to reach the bladder and ureteral opening, removes an indwelling ureteral stent, and places a replacement. Fluoroscopy may be used to guide or confirm placement. Exchanges commonly maintain drainage when a stent is due for replacement, becomes obstructed or encrusted, or remains necessary during treatment of stones, ureteral narrowing, or postoperative obstruction. The service is commonly performed in an operating room or ambulatory surgery setting, and may also be performed in an office when appropriate.
Report 50385 for a completed exchange, rather than removal alone or initial stent placement without an existing stent to replace. Documentation should identify the side, indication, existing stent removal, replacement placement, and transurethral approach. Routine cystoscopic access for the exchange is part of the service. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

50385 billing questions
How does 50385 differ from 50386?
50385 represents removal of an existing ureteral stent followed by placement of a replacement. Use 50386 when the stent is removed without an exchange.
When is 50382 more appropriate?
50382 describes a ureteral stent exchange performed percutaneously. 50385 is for an exchange performed through the urethra.
Can routine cystoscopy be billed separately?
Cystoscopic access used to carry out the transurethral exchange is part of 50385. Do not separately report a diagnostic cystoscopy solely for that access.
What documentation supports reporting 50385?
Document the indication and side, the existing stent's removal, placement of the replacement stent, and the transurethral route.
How is bilateral reporting handled?
CMS pays a bilateral service reported with modifier 50 at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%.
