Summary & Overview
CPT 52351: Diagnostic Cystourethroscopy with Ureteroscopy/Pyeloscopy
CPT code 52351 captures a diagnostic endoscopic urologic service: cystourethroscopy with ureteroscopy and/or pyeloscopy for inspection of the bladder, urethra, ureteric openings, ureters, and renal pelvis. This procedure is a foundational diagnostic tool in urology for evaluating hematuria, suspected ureteral pathology, urinary tract calculi, and structural abnormalities. Nationally, accurate coding of this service affects clinical documentation, facility planning, and payer reimbursement for endoscopic diagnostic procedures.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for the procedure, common settings where the service is provided, and typical billing considerations tied to this code. The publication outlines benchmarks commonly tracked for endoscopic urologic diagnostics, summarizes policy and coverage themes that influence utilization, and highlights areas where documentation supports correct code assignment. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 52351 describes a diagnostic cystourethroscopy with ureteroscopy and/or pyeloscopy. The procedure involves inspection of the interior of the bladder, the urethra (including the prostatic urethra), and the ureteric orifices using a cystoscope passed through the urethra into the bladder, along with inspection of the ureters and optionally the renal pelvis via ureteroscopy and/or pyeloscopy.

Service type: Diagnostic endoscopic urologic procedure
-
Typical site of service: Ambulatory surgical center or hospital outpatient department; may also be performed in an office setting with appropriate equipment and staffing
Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old male presenting with episodic gross hematuria and flank pain. After initial evaluation (history, urinalysis, urine culture, and CT urogram), the urology team schedules a diagnostic cystourethroscopy with ureteroscopy/pyeloscopy to directly visualize the bladder, urethra, prostatic urethra, ureteral orifices, and the ureters/renal pelvis to identify sources of bleeding, evaluate suspected ureteral calculi, inspect urothelial lesions, or obtain targeted biopsies or washings. The procedure is performed in an ambulatory surgical center or hospital operating room under monitored anesthesia care or general anesthesia. The workflow includes preoperative consent and evaluation, operating room setup with a flexible or rigid cystoscope and ureteroscope, cystoscopic inspection, selective ureteroscopy/pyeloscopy bilaterally as indicated, collection of specimens (urine cytology, biopsy or brushings) if lesions are seen, and postoperative recovery with discharge instructions. Hemostasis, documentation of findings, specimen labeling, and postprocedural pathology orders complete the encounter.
