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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

52343 billing questions

When should 52346 be reported instead?

How does this differ from 52342?

52343 is for a stricture within the kidney’s collecting system. 52342 identifies treatment at the ureteropelvic junction.

What documentation supports 52343?

The operative report should identify the renal collecting-system stricture, describe the treatment performed, and make clear whether ureteroscopy or pyeloscopy was used.

How is bilateral treatment handled?

CMS lists this as a bilateral procedure: modifier 50 is paid at 150%. The record should support treatment on both sides.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 52343. Co-surgeons and team surgery are not permitted.

How does CMS price related endoscopies performed together?

When related endoscopies are performed together, CMS applies endoscopy family pricing. The code also has a 0-day global period, which includes same-day preoperative and postoperative care.
