What 52320 covers
A urologist uses a cystoscope to access the bladder and ureteral opening, then passes instruments through the scope to retrieve a ureteral calculus. The service includes ureteral catheterization and is generally selected when the stone is removed intact with an extraction instrument, such as a basket, rather than broken apart. It is performed in an operating room or another setting equipped for endoscopic urologic treatment.
The operative note should identify the ureteral stone and document its retrieval, the approach, and whether fragmentation was performed. Report a code for fragmentation when the calculus is broken up, and distinguish this service from removal of a stone located in the bladder. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Endoscopy family pricing applies when related endoscopies are performed together. For bilateral treatment reported with modifier 50, CMS pays at 150%. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.
