Summary & Overview
CPT 52342: Cystourethroscopy with Ureteral Catheterization to UPJ for Stricture Treatment
CPT code 52342 denotes cystourethroscopy with insertion of a catheter into the ureter up to the ureteropelvic junction (UPJ) for treatment of a UPJ stricture. The code captures both endoscopic inspection of the bladder, urethra and ureteric orifices and therapeutic maneuvers performed at the UPJ. This procedure is clinically important as it addresses obstructive pathology at the UPJ that can cause pain, recurrent infections, and renal impairment if untreated.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when 52342 is reported, the typical sites of service (ambulatory surgery centers and hospital outpatient departments), and what the code represents in procedural terms. The publication also outlines common billing modifiers and related administrative considerations where provided. The material is intended to inform policy, billing, and coding stakeholders about the clinical scope of the code and what elements typically define its use. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 52342 describes a cystourethroscopy with insertion of a catheter into the ureter up to the ureteropelvic junction (UPJ) for treatment of a UPJ stricture. The procedure involves inspection of the interior of the bladder, the urethra, the prostatic urethra, and the ureteric orifices using a cystoscope passed through the urethra into the bladder, followed by passage of a catheter tip into and through the ureter to the UPJ where the provider selects an appropriate endoscopic method to treat the stricture.
-
Service type: Endoscopic urologic procedure for diagnostic inspection and endourologic treatment of a ureteropelvic junction stricture
-
Typical site of service: Ambulatory surgery center or hospital outpatient department, performed using cystoscopic/ureteroscopic access to the bladder and ureter
Clinical & Coding Specifications
Clinical Context
A 52-year-old male presents with progressive flank pain and intermittent urinary tract infections. Imaging (CT urogram) demonstrates hydronephrosis and a suspected ureteropelvic junction (UPJ) stricture on the left. The urologist schedules a cystourethroscopy with retrograde ureteral catheterization and endoscopic treatment of the UPJ stricture. In the operating room or ambulatory surgery center under general or regional anesthesia, the provider performs a diagnostic cystourethroscopy to inspect the bladder, urethra, and ureteral orifices. A guidewire and catheter are passed into the affected ureter up to the UPJ; endoscopic management is selected (endopyelotomy incising the stricture or balloon dilation) per intraoperative findings. Post-procedure, a ureteral stent may be placed for drainage. Typical workflow includes preoperative consent, imaging review, cystoscopic access, retrograde pyelogram as needed, endoscopic treatment of the UPJ stricture, stent placement if indicated, and postoperative recovery with stent removal scheduled in follow-up.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Normal, straightforward service | Use when this procedure is performed without unusual circumstances and is the primary billed service. |
22 | Increased procedural services | Use when work required is substantially greater than usual (extensive adhesions, prolonged operative time) with documentation.
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned.
53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances.
59 | Distinct procedural service | Use when another separate procedure not normally reported together is performed at a separate site or session.
62 | Two surgeons | Use when two surgeons collaborate during a complex endoscopic reconstruction.
63 | Procedure performed on infants less than 4 kg | Rarely applicable; use only when patient size qualifier applies.
73 | Discontinued outpatient hospital/ASC prior to anesthesia | Use if the procedure is cancelled after patient preparation but before anesthesia in ASC/hospital outpatient.
78 | Unplanned return to the operating room by the same physician following initial procedure for a related procedure during the postoperative period | Use if a repeat endoscopic intervention is required during the global period.
80 | Assistant surgeon | Use when an assistant surgeon participates and is not the primary surgeon.
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an advanced practice clinician assists in surgery per payer policy.
LT | Left side | Use to identify laterality for left-sided UPJ procedure when required by payer.
RT | Right side | Use to identify laterality for right-sided UPJ procedure when required by payer.
59 | Distinct procedural service | See above; used when coding separate endoscopic procedures in same session with appropriate documentation.

N13.8 | Other obstructive and reflux uropathy | Used when obstruction involves multiple sites or atypical presentations related to UPJ pathology.
