Urology
About 50576: Renal endoscopic calculus removal
Reports renal endoscopy through a surgical kidney incision to remove a calculus, rather than treating the stone through an established nephrostomy tract.
A urologist uses an endoscope introduced through a nephrotomy or pyelotomy to access the kidney and remove a calculus. The procedure is performed in an operating room, typically when a stone is managed through this surgically created access route. The code represents the endoscopic stone-removal service; the approach distinguishes it from treatment through an established nephrostomy or pyelostomy access.
Select the code when the operative report supports renal endoscopy by this route and documents calculus removal. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
