Official Description

Cystourethroscopy; with treatment of ureteropelvic junction stricture (eg, balloon dilation, laser, electrocautery, and incision)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 52342 involves cystourethroscopy, which is a minimally invasive surgical technique used to visualize and treat conditions affecting the ureter and the ureteropelvic junction (UPJ). During this procedure, a cystourethroscope—a specialized endoscopic instrument—is inserted through the urethra and advanced into the bladder, allowing the physician to access the ureter. The primary purpose of this procedure is to address strictures, which are narrowings that can occur in the ureter or at the junction where the ureter meets the kidney (UPJ). These strictures can lead to obstruction and may cause significant complications, including pain, urinary tract infections, and kidney damage. The treatment options during this procedure may include balloon dilation, which involves the use of a balloon catheter to widen the narrowed area; laser therapy, which utilizes focused light energy to cut or vaporize tissue; electrocautery, which employs electrical current to remove or shrink tissue; and incision techniques that involve cutting through the stricture to restore normal urine flow. The procedure is performed under ureteroscopic control, ensuring precision in navigating the urinary tract and effectively treating the stricture. The ultimate goal is to alleviate the obstruction, restore normal urinary function, and prevent further complications associated with ureteral strictures.

1. Indications

The procedure described by CPT® Code 52342 is indicated for the treatment of strictures located at the ureteropelvic junction (UPJ) or within the ureter. The following conditions may warrant this procedure:

  • Ureteropelvic Junction Stricture - A narrowing at the junction where the ureter connects to the renal pelvis, which can obstruct urine flow from the kidney.
  • Ureteral Stricture - A narrowing within the ureter that can impede the passage of urine from the kidney to the bladder.
  • Intra-renal Stricture - A narrowing that occurs within the renal pelvis or calyces, affecting urine drainage from the kidney.

2. Procedure

The procedure for CPT® Code 52342 involves several key steps to effectively treat the stricture:

  • Step 1: Insertion of Cystourethroscope - The physician begins by inserting a cystourethroscope into the urethra and advancing it through the bladder to reach the ureter. This allows for direct visualization of the urinary tract.
  • Step 2: Guidewire Placement - Under ureteroscopic control, a guidewire is passed through the area of the stricture. This guidewire serves as a pathway for subsequent instruments.
  • Step 3: Ureteroscope Advancement - A semi-rigid or flexible ureteroscope is then advanced alongside the guidewire to the site of the stricture, providing enhanced access and visualization.
  • Step 4: Balloon Dilation - A balloon dilator may be introduced and inflated at the site of the stricture. This dilation process helps to widen the narrowed area, facilitating better urine flow.
  • Step 5: Incision of the Stricture - Following dilation, the physician may perform an incision of the stricture using an endoincision technique. This can be accomplished with a laser fiber, electrocautery, or other endoscopic surgical tools, ensuring that incisions are made through the full thickness of the ureter or UPJ until the surrounding fat is encountered.
  • Step 6: Final Dilation - Dilation and/or incisions are made along the length of the stricture until the ureteroscope can be passed through the area of the stricture, confirming successful treatment.
  • Step 7: Placement of Indwelling Stent - A temporary indwelling stent is placed across the surgical site to maintain patency and facilitate urine drainage post-procedure.
  • Step 8: Removal of Instruments - Finally, all surgical instruments are removed, completing the procedure.

3. Post-Procedure

After the completion of the procedure, patients may require monitoring for any immediate complications. The placement of a temporary indwelling stent is crucial for ensuring proper urine flow and preventing obstruction at the surgical site. Patients may experience some discomfort, and it is important to provide appropriate post-operative care instructions, including hydration and monitoring for signs of infection or complications. Follow-up appointments may be necessary to assess the effectiveness of the treatment and to determine if further interventions are needed.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
