CPT code 50075 denotes an open surgical procedure to remove a large staghorn (struvite) renal calculus via an incision in the kidney. This code captures a high-complexity urologic operation that is clinically important because staghorn stones can compromise renal function, are often infection-associated, and typically require definitive surgical management. Nationally, management of complex renal calculi carries significant clinical and resource implications for inpatient surgical care, anesthesia, and post-operative monitoring.

Key payers included in this review are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the scope of services represented by the code. The publication summarizes common billing and coding considerations, lists frequently used modifiers (input provided), and highlights where data is not available in the input. It also outlines what to expect in payer coverage discussions and benchmarking topics—including utilization patterns, authorization considerations, and payment policy variations—so clinicians, billing teams, and policy analysts understand the operational implications for managing complex renal stone disease at a national level.
