What 50972 covers
The urologist passes an endoscope through an existing ureterostomy to examine the ureter and inserts a ureteral catheter. The service is used when access is through the stoma rather than the urethra, such as during evaluation or management of a patient with a surgically created ureterostomy. It is performed by a urologist in an operating room or another setting equipped for endoscopic urinary tract procedures.
Select this code when the documented procedure includes both ureteroscopy through the ureterostomy and catheter insertion; a diagnostic examination alone or an added biopsy or treatment belongs to a different code in the family. The operative report should identify the route, ureter examined, catheter placement, and any additional work. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. 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.

50972 billing questions
When should I choose 50972 instead of 50970?
Use 50972 when ureteroscopy through a ureterostomy includes insertion of a ureteral catheter. Use 50970 for the endoscopic service without catheter insertion.
Can a biopsy or ureteral treatment be included in 50972?
When the procedure includes biopsy or a separately defined therapeutic service, select the applicable code for that work rather than treating 50972 as a general ureteroscopy code. The operative report should make the work performed clear.
How is bilateral 50972 reported?
Report bilateral performance with modifier 50. CMS pays the bilateral procedure at 150%.
Does the 0-day global period include same-day care?
Yes. Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
Can an assistant surgeon be paid for 50972?
Assistant-at-surgery payment is available only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
