CPT code 51045 denotes a cystotomy approach to place a ureteral stent or catheter to relieve a ureteral stricture or blockage. This code captures a targeted urologic surgical intervention used to restore urinary drainage and prevent complications from obstructive uropathy. Nationally, accurate coding for this procedure matters for clinical documentation, quality measurement, and appropriate facility and professional billing.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, as well as what to expect in payer coverage considerations and common billing practices. The publication summarizes relevant benchmarks, coding nuances, and recent policy developments that affect authorization, site-of-service designation, and bundling or global period implications. Clinical implications such as indications (ureteral stricture or obstruction), expected perioperative setting (hospital operating room, ambulatory surgery center), and the primary goals of the procedure (restoring ureteral patency, relieving obstruction) are covered to support coding accuracy and administrative review.

Data not available in the input is noted where applicable, and readers will be directed to payer-specific policies and clinical guidelines for authorization criteria and documentation requirements.
