Summary & Overview
CPT 51595: Radical Cystectomy with Urinary Diversion
CPT code 51595 designates radical cystectomy with extensive bilateral pelvic lymphadenectomy and construction of a urinary diversion (ureteroileal conduit or sigmoid neobladder). This major oncologic urologic operation is performed primarily for bladder cancer and is a high-resource inpatient surgical procedure with substantial clinical and reimbursement implications nationally. Key payers commonly involved in coverage decisions for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent of the code, where the procedure is typically performed, and the types of urinary diversion included in the descriptor. The publication provides benchmarks and coding considerations relevant to hospital inpatient service lines, summarizes common modifiers used in surgical coding for complex intraoperative circumstances, and highlights the clinical context that drives utilization of this code. The material is intended for revenue cycle professionals, surgical coders, and policy analysts seeking a national perspective on procedural classification and operational implications for inpatient urologic oncology care. Data not included in the input (such as payer-specific reimbursement rates, associated taxonomies, and ICD-10 diagnosis mappings) are noted as unavailable where applicable.
Billing Code Overview
CPT code 51595 describes a radical cystectomy with extensive bilateral pelvic lymph node dissection and creation of a urinary diversion. The procedure includes complete surgical removal of the urinary bladder with removal of external iliac, hypogastric, and obturator lymph nodes, followed by reconstruction to maintain urinary outflow.
Service type: Major open abdominal urologic surgery with urinary diversion
Typical site of service: Inpatient hospital operating room with inpatient postoperative admission
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old male with muscle-invasive urothelial carcinoma of the bladder scheduled for radical cystectomy with urinary diversion. The patient has undergone preoperative staging (CT chest/abdomen/pelvis) confirming organ-confined disease without distant metastases, and preoperative counseling with urology and anesthesia staff. On the day of surgery the patient receives general endotracheal anesthesia, prophylactic antibiotics, venous thromboembolism prophylaxis, and bowel preparation per institutional protocol. The surgical team performs a radical cystectomy with extensive bilateral pelvic lymph node dissection (external iliac, hypogastric/internal iliac, and obturator nodes). To reestablish urinary continuity the surgeon creates a urinary diversion such as a ureteroileal conduit or an orthotopic neobladder created from sigmoid colon (sigmoid bladder) and performs bowel anastomosis to restore continuity. Intraoperative specimens are sent to pathology. Postoperative workflow includes immediate postoperative monitoring in the PACU, inpatient surgical ward care with pain control, early mobilization, stoma care education if a conduit was created, monitoring for surgical complications (bleeding, infection, anastomotic leak, ureteral obstruction), and coordination of adjuvant oncology as indicated.
