What 52353 covers
A urologist passes an endoscope through the bladder into the ureter or kidney collecting system and uses laser or another energy source to break a stone into smaller pieces. The procedure is commonly performed in a hospital operating room or ambulatory surgery center for ureteral or renal calculi that require endoscopic fragmentation.
Report this code when the operative record supports both endoscopic access to the ureter or kidney and active stone fragmentation. Distinguish it from endoscopic stone removal without fragmentation and from diagnostic inspection alone. If an indwelling ureteral stent is inserted as part of the lithotripsy, code 52356 describes that combination. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. For bilateral procedures, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

How to choose
- 52352Ureteroscopy
- 52352 is for endoscopic stone removal or manipulation without lithotripsy. Choose 52353 when the operative report documents energy-based fragmentation.
- 52356Ureteroscopic lithotripsy
- 52356 combines ureteroscopic or pyeloscopic lithotripsy with insertion of an indwelling ureteral stent. Use 52353 when that stent insertion is not part of the procedure.
- 52351Ureteroscopy
- 52351 describes diagnostic ureteroscopic or pyeloscopic inspection. It does not describe the stone fragmentation reported with 52353.
- 52325Stone fragmentation
- 52325 describes ureteral-calculus fragmentation using a different endoscopic approach; 52353 involves ureteroscopy or pyeloscopy with lithotripsy.
52353 billing questions
When should 52353 be chosen instead of 52352?
Use 52353 when the surgeon fragments a ureteral or renal stone with energy during ureteroscopy or pyeloscopy. Code 52352 describes endoscopic stone removal or manipulation without lithotripsy.
How does 52353 differ from 52356?
52356 describes ureteroscopic or pyeloscopic lithotripsy with insertion of an indwelling ureteral stent. When that stent insertion is part of the lithotripsy procedure, report 52356 rather than separately adding 52332 to 52353.
What documentation supports 52353?
The operative report should identify the treated stone and document endoscopic access to the ureter or kidney, the energy-based fragmentation performed, and the treatment site.
Can modifier 50 be used for bilateral treatment?
CMS lists this as a bilateral procedure; when performed bilaterally and reported with modifier 50, payment is at 150%.
How are related endoscopic procedures paid when performed together?
Medicare applies endoscopy family pricing when related endoscopies are performed together. The procedure also has a 0-day global period, which includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
