Cystourethroscopy, with insertion of indwelling ureteral stent (e.g., Gibbons or double-J type)

Cystourethroscopy with insertion of an indwelling ureteral stent (e.g., Gibbons or double-J type) involves the endoscopic visualization of the urethra and bladder to facilitate the placement of a stent into the ureter. The stent is typically advanced over a guidewire, often under fluoroscopic guidance, to maintain or restore patency of the ureter, allowing urine to drain from the kidney to the bladder. This procedure is commonly performed to bypass an obstruction, protect the ureter during surgery, or assist in stone passage. The proximal end of the stent resides in the renal pelvis, and the distal end coils in the bladder.

Clinical Indications

  • Ureteral obstruction due to calculi (kidney or ureteral stones)
  • Ureteral strictures (benign or malignant)
  • Extrinsic compression of the ureter by tumors (e.g., pelvic malignancies)
  • Protection of the ureter during or after complex surgical procedures (e.g., open or laparoscopic pelvic surgery, ureteroscopy, extracorporeal shock wave lithotripsy (ESWL))
  • Management of ureteral injury or fistula
  • Preoperative drainage of an obstructed kidney prior to definitive surgical intervention
  • To facilitate the passage of stone fragments following lithotripsy or ureteroscopy
  • Management of refractory vesicoureteral reflux in select cases

Procedure Steps

  1. Patient positioned in lithotomy position; sterile preparation and draping.
  2. Cystoscope is inserted transurethrally into the bladder, and the bladder is distended with irrigant.
  3. Bladder is inspected, and ureteral orifice(s) are identified.
  4. A guidewire is advanced through the cystoscope into the affected ureteral orifice and manipulated up into the renal pelvis, often with fluoroscopic guidance to confirm placement.
  5. The ureteral stent (e.g., double-J or Gibbons type) is advanced over the guidewire into the ureter until the proximal coil is positioned in the renal pelvis and the distal coil is positioned in the bladder.
  6. The guidewire is carefully withdrawn, and proper stent position is confirmed, typically with fluoroscopy.
  7. Cystoscope is withdrawn.

Coding Guidelines

  • CPT code 52332 describes the insertion of an indwelling ureteral stent via cystourethroscopy and includes the diagnostic cystourethroscopy component.
  • Fluoroscopic guidance (e.g., 76000, 77002, 77003) for the placement of the ureteral stent is generally considered an integral part of CPT 52332 and is typically not separately reportable. Some payers may allow separate reporting of fluoroscopy for unusual or complex cases with appropriate documentation and modifier.
  • If a diagnostic cystourethroscopy (e.g., 52000) is performed as a distinct service immediately prior to the decision for stent placement, it may be separately reportable with modifier 59 or XU, if documentation clearly supports it as a separate and distinct procedure.
  • This code does not include the removal of a previously placed stent. Stent removal is reported with 52310 (removal from urethra/bladder) or 52315 (removal from ureter).
  • If ureteral dilation is performed to allow for stent placement, it is generally considered inclusive to the stent insertion (52332) and not separately coded unless it meets specific criteria for a distinct service (e.g., significant stricture requiring complex dilation prior to stent placement).
  • This procedure has a 0-day global period for Medicare.
