CPT code 50750 denotes ureterocalycostomy, a surgical procedure that connects the upper pole of a healthy, nondilated ureter to a renal calyx to bypass a ureteropelvic junction obstruction and restore upper urinary tract drainage. Nationwide, this code represents a specialized reconstructive urologic surgery used when more common corrective surgeries are not feasible, making it important for surgical coding, coverage decisions, and hospital resource planning.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and typical sites of service, commonly applied modifiers, and guidance on what to expect in payer coverage patterns. The publication summarizes national benchmarks for utilization where available, highlights relevant policy and documentation considerations for surgical reconstruction claims, and provides clinical context on when ureterocalycostomy is indicated versus alternative procedures.

This coverage-oriented summary is intended for coding professionals, surgical departments, and payer policy teams seeking a national perspective on the clinical purpose of CPT code 50750, its role in urologic reconstruction, and the primary topics to address in claims and policy reviews.
