CPT code 51580 denotes a radical cystectomy — the complete surgical removal of the urinary bladder and adjoining organs with construction of a urinary diversion. This procedure is most commonly performed for multifocal or recurrent bladder cancer and represents a high-acuity, resource-intensive inpatient surgical service with significant implications for surgical teams, hospital capacity, and payment policy nationally. Payers commonly managing coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find clinical context about the operative intent and typical care setting, an explanation of what the code captures for claims processing, and a framework for understanding where this procedure fits within surgical oncology and urologic services. The publication summarizes common modifiers associated with high-complexity inpatient surgery and notes where specific billing or policy updates may affect reimbursement workflows. It also outlines expected documentation elements tied to major abdominal/urologic operations and urinary diversion construction. Where input fields were incomplete, the text states data availability explicitly. This overview is written for a national audience of clinicians, coding staff, and policy analysts seeking a concise reference to CPT code 51580 and its role in care delivery and claims administration.
