Summary & Overview
CPT 51575: Radical Cystectomy with Pelvic Lymph Node Dissection
CPT code 51575 represents a radical cystectomy with bilateral pelvic lymph node dissection — a definitive surgical treatment for multifocal or extensive bladder cancer. This code captures a complex inpatient oncologic procedure that has significant implications for surgical oncology workflows, resource utilization, and postoperative care pathways. Nationally, radical cystectomy remains a high-acuity, high-cost procedure with implications for hospital quality metrics, length of stay, and multidisciplinary cancer care coordination.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when CPT code 51575 is used, typical sites of service, and the procedural elements captured by the code. The publication also summarizes payer coverage considerations, common billing modifiers associated with major surgical procedures, and areas where policy updates or billing guidance can affect claims processing and reimbursement. Finally, the report outlines benchmarks and operational considerations relevant to surgeons, hospital administrators, and revenue cycle teams managing care for patients undergoing radical cystectomy.
Billing Code Overview
CPT code 51575 describes a surgical procedure for complete removal of the urinary bladder (radical cystectomy) with concurrent bilateral pelvic lymph node dissection, including removal of the external iliac, hypogastric, and obturator nodes. The procedure is indicated when bladder cancer is present in multiple areas of the bladder and requires removal of both the organ and regional lymphatic tissue.
-
Service type: Major open surgical oncologic procedure (radical cystectomy with pelvic lymphadenectomy)
-
Typical site of service: Hospital operating room with inpatient admission for postoperative care
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with multifocal, muscle-invasive urothelial carcinoma of the bladder presents after staging with contrast CT showing tumor involvement in multiple bladder regions and suspicious pelvic lymphadenopathy. Following multidisciplinary tumor board review, the patient is scheduled for a radical cystectomy with bilateral pelvic lymph node dissection due to high-grade disease and risk of local/regional spread. Preoperative workup includes cystoscopy with biopsy confirming invasive urothelial carcinoma, chest imaging to assess for metastasis, cardiopulmonary clearance, and discussion of urinary diversion options (ileal conduit versus continent diversion). On the day of surgery, under general anesthesia, the urologic oncology surgeon performs removal of the entire urinary bladder, pelvic lymphadenectomy including external iliac, hypogastric (internal iliac), and obturator nodes bilaterally, and constructs the selected urinary diversion. Intraoperative considerations include blood loss management, possible transfusion, nerve-sparing decisions, and frozen section assessment of margins when indicated. Postoperatively the patient is monitored in a surgical unit with pain control, early ambulation, catheter and stoma care education if applicable, and coordination for adjuvant oncology care if pathology indicates.
