What 52300 covers
A urologist uses a cystoscope to incise or resect a ureterocele, a pouch-like enlargement of the ureter’s opening into the bladder. The endoscopic treatment opens the ureterocele to improve drainage, such as when it contributes to urinary obstruction, hydronephrosis, or recurrent infection. The procedure is commonly performed in a hospital or ambulatory surgery setting; the code includes ureteral catheterization when performed as part of the service.
Report the code when the operative note supports incision or resection of a ureterocele, rather than stone treatment, stricture treatment, or stent work alone. Document the ureterocele’s location, the indication, and the treatment performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. CMS prices it as bilateral, and modifier 50 does not increase payment. Endoscopy family pricing applies when related endoscopies are performed together. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

52300 billing questions
When should this code be chosen over a ureteral stricture code?
Use this code for endoscopic incision or resection of a ureterocele. A ureteral stricture code describes treatment directed at a narrowed ureteral segment.
Is ureteral catheterization included?
Yes. Ureteral catheterization is included in the service when performed as part of the ureterocele procedure.
Can a separately placed ureteral stent be reported?
A temporary catheterization is not the same as placement of an indwelling stent. If a stent is inserted, document that distinct work and review applicable coding edits before reporting an additional code.
Should modifier 50 be appended for treatment on both sides?
CMS prices this code as bilateral, and modifier 50 does not increase payment.
What global-period care is included?
The 0-day global period includes same-day preoperative and postoperative care. Care on later dates is outside that same-day package.
What supports payment for an assistant at surgery?
The record must document medical necessity for the assistant. CMS does not permit co-surgeons or team surgery for this code.
