What 52343 covers
This procedure opens a stricture within the kidney’s collecting system using instruments passed through the urethra and bladder. The urologist may dilate or incise the narrowed area, such as when it obstructs urine drainage. The code distinguishes treatment without ureteroscopy or pyeloscopy; when those scopes are used to treat the renal stricture, the corresponding code is 52346. These procedures are generally performed in a facility operating room.
Select the code based on the stricture’s documented anatomic site and the endoscopic approach. The operative report should identify the renal collecting-system narrowing and describe how it was treated, including whether ureteroscopy or pyeloscopy was used. CMS 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 treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
