Urology
About 50555: Renal endoscopy with tissue biopsy
Reports endoscopic inspection of the renal collecting system through a nephrotomy or nephrostomy route when tissue is sampled for examination.
A urologist uses an endoscope passed through a surgical opening into the kidney or an existing nephrostomy tract to inspect the renal collecting system and obtain tissue. The biopsy may target abnormal tissue identified during the examination. This service is typically performed in a facility setting, such as an operating room, when direct access to the kidney is available or created for the procedure.
Report this code when the operative note supports both renal endoscopy through the nephrotomy or nephrostomy route and tissue sampling. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies in the endoscopy family are performed together, CMS applies endoscopy family pricing. For bilateral procedures reported with modifier 50, CMS pays at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
