Summary & Overview
CPT 50815: Colonic Urinary Conduit for Urinary Diversion
CPT code 50815 represents a major urologic reconstructive operation in which a segment of colon is fashioned into a urinary conduit with formation of a stoma. This procedure is typically performed when the bladder has been removed or is nonfunctional due to cancer or other serious disease, and it serves as a definitive urinary diversion technique. Nationally, CPT code 50815 is relevant to hospitals, urology and colorectal surgical services, and payers managing high-cost, complex inpatient surgical care.
Key payers in standard coverage analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers can expect an overview of clinical context for colonic urinary conduits, common sites of service and care settings, and the billing and claims environment for major inpatient urinary diversion procedures. The publication outlines expected service lines, typical inpatient hospital use, and payer considerations relevant to reimbursement and prior authorization workflows. It also summarizes how this surgical option fits into broader care pathways for patients undergoing cystectomy or requiring permanent urinary diversion.
This resource is intended for coding managers, denials and reimbursement analysts, surgical service line leaders, and payers seeking a concise reference to the clinical and billing characteristics of CPT code 50815. Data not available in the input: detailed modifiers, associated taxonomies, specific ICD-10 diagnoses, related codes, and payer-specific payment benchmarks.
Billing Code Overview
CPT code 50815 describes a surgical procedure in which a segment of colon is used to create a urinary conduit. The surgeon opens the colon, implants a ureter into the colon incision, and brings the colon end through the abdominal wall to form a stoma for urinary diversion. The remaining colon is reattached to restore intestinal continuity.

Service type: Major reconstructive urologic surgery for urinary diversion using colon (urinary conduit with colonic segment)
-
Typical site of service: Hospital operating room, inpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old male with muscle-invasive bladder cancer who previously underwent radical cystectomy. The patient presents for creation of a urinary conduit using a segment of colon (colon conduit/colonic conduit urinary diversion) because the native bladder has been removed and urinary diversion is required. Preoperative evaluation includes history and physical, cross-sectional imaging (CT abdomen/pelvis), laboratory studies, and bowel preparation as indicated. The operative workflow: the colorectal or urologic surgeon identifies and isolates an appropriate colon segment, mobilizes the segment while preserving blood supply, makes an enterotomy on the colon for ureteral implantation, anastomoses each ureter to the colonic mucosa, re-establishes colonic continuity with a colorectal anastomosis, matures the proximal colon stoma to the abdominal wall, and ensures urinary drainage via a stoma appliance. Intraoperative steps include ureteral stent placement as needed, hemostasis, and abdominal closure. Typical postoperative care includes monitoring urine output, stoma care education, pain control, early ambulation, and surveillance for complications such as urinary leak, infection, bowel obstruction, or metabolic disturbances. Typical site of service: inpatient hospital operating room with postoperative inpatient stay. Service type: major surgical open abdominal procedure for urinary diversion.
