CPT Code Overview

CPT 52356 describes a surgical procedure in urology involving cystourethroscopy with ureteroscopy and/or pyeloscopy, combined with lithotripsy and the insertion of an indwelling ureteral stent, such as a Gibbons or double‑J type. This procedure is typically performed to treat urinary stones and facilitate drainage in the urinary system. The most common sites of service for this procedure are hospital outpatient departments or ambulatory surgery centers, corresponding to place of service codes POS 19 or 24. This code is central to surgical management of urinary tract stones and related conditions, reflecting advanced endoscopic techniques in urology.

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves an adult presenting with symptoms such as flank pain, hematuria, or dysuria. Imaging studies reveal a urinary stone located in the ureter or kidney. The patient is scheduled for a surgical procedure in a hospital outpatient department or ambulatory surgery center (place of service 19 or 24). The urologist performs a cystourethroscopy with ureteroscopy and/or pyeloscopy, uses lithotripsy to fragment the stone, and inserts an indwelling ureteral stent (such as a Gibbons or double-J type) to ensure patency of the ureter post-procedure. This workflow is typical for management of urinary calculi that require endoscopic intervention and stenting.

Coding Specifications

Modifier 51: Indicates multiple procedures were performed during the same session. Used when more than one surgical procedure is completed.
Modifier 59: Denotes a distinct procedural service. Used when procedures are not normally reported together but are appropriate due to different sites or circumstances.
