Summary & Overview
CPT 51585: Radical Cystectomy with Urinary Diversion
CPT code 51585 denotes radical cystectomy with removal of the bladder, adjacent pelvic organs, bilateral pelvic lymphadenectomy, and concurrent urinary diversion. This major urologic oncology procedure is most commonly performed for multifocal bladder cancer or recurrent disease and is a key intervention affecting surgical oncology capacity, inpatient surgical volumes, and post‑acute care needs nationally. Covered payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise clinical context explaining the procedure and its typical inpatient setting, an overview of common billing modifiers and coding considerations, and national payer coverage notes. The publication highlights expected service line impacts, including operating room resources, length of stay considerations, and typical post‑operative care pathways. Where available, benchmarks on utilization and reimbursement trends are summarized alongside policy updates relevant to surgical oncology and inpatient authorization practices. Data not available in the input will be noted explicitly in the detailed sections of the full publication.
Billing Code Overview
CPT code 51585 describes a complete cystectomy with bilateral pelvic lymph node dissection and urinary diversion. The procedure involves removal of the urinary bladder and adjoining organs, with surgical re‑routing of urine either by implanting the ureters into the colon or by creating a urinary stoma connecting the urethra to the skin.
Service type: Major open abdominal pelvic surgery (urologic oncology procedure)
Typical site of service: Inpatient hospital or tertiary care center operating room with post‑operative inpatient stay

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of multifocal high-grade urothelial carcinoma of the bladder presents for radical cystectomy with urinary diversion. Prior transurethral resections and intravesical therapy failed, and imaging plus biopsy confirm multiple tumor foci and muscle-invasive disease. The surgical team admits the patient to an inpatient surgical unit. Preoperative evaluation includes oncology consultation, anesthesia assessment, and optimization of comorbidities (cardiac, pulmonary, diabetes). On the day of surgery, general anesthesia is induced, broad-spectrum prophylactic antibiotics administered, and a midline laparotomy or robotic approach is used. The surgeon performs a complete extirpation of the bladder with removal of adjoining organs and bilateral pelvic lymph node dissection. Urinary diversion is constructed during the same operation, either an ileal conduit (ureteroenteric anastomosis) or continent reservoir, or cutaneous ureterostomy as indicated by intraoperative findings and patient factors. Postoperatively the patient is transferred to a post-anesthesia care unit and then to a surgical ward or intensive care unit based on stability. Typical inpatient stay spans several days to weeks depending on recovery, complications, and need for adjuvant therapy. Billing uses 51585 to report the complete cystectomy with urinary diversion as described.
