Summary & Overview
CPT 50688: Ureterostomy Tube or Ureteral Stent Exchange via Ileal Conduit
CPT code 50688 covers removal and exchange of an existing ureterostomy tube or an externally accessible ureteral stent via an ileal conduit. The procedure is an important urologic device-management service that preserves urinary drainage and prevents conduit complications after urinary diversion. Nationally, these exchanges occur in ambulatory surgical centers, hospital outpatient departments, and sometimes inpatient settings for complex patients.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis addresses coverage patterns, typical sites of service, and clinical context relevant to reimbursement and coding consistency across payers.
Readers will learn the clinical purpose of the code, typical service settings, common billing considerations, and where to find payer-specific policy detail. The publication summarizes benchmarks and policy updates where available and highlights operational points relevant to coding and billing teams, clinicians managing ileal conduits, and revenue cycle stakeholders.

Billing Code Overview
CPT code 50688 describes a procedure in which the provider removes an existing ureterostomy tube or an externally accessible ureteral stent that is routed through an ileal conduit, and exchanges that tube or stent for a new one. This procedure typically involves accessing the external stoma or conduit, removing the in-place tube or stent, and placing a replacement to maintain urinary drainage and conduit patency.
-
Service type: Tube or stent removal with exchange via an ileal conduit (interventional/urologic device management)

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with an existing ileal conduit urinary diversion who presents for routine exchange or removal of an externally accessible ureteral stent or ureterostomy tube. Common indications include routine stent/tube maintenance to prevent encrustation or obstruction, device malfunction, dislodgement, urinary leakage around the tube, recurrent urinary tract infection, or planned removal after healing. The clinical workflow begins with outpatient pre-procedure evaluation (history, focused exam, medication review, anticoagulation assessment), verification of the conduit stoma and device type, and appropriate informed consent. The procedure is usually performed in an ambulatory surgery center, clinic procedure room, or hospital outpatient department under local anesthesia with or without conscious sedation. The provider disconnects and removes the existing externally accessible ureteral stent or ureterostomy tube through the ileal conduit and, when indicated, inserts and secures a replacement tube/stent. Post-procedure care includes monitoring for bleeding, urine output, pain control, stoma site assessment, and discharge instructions for tube care and signs of complications. Typical documentation elements include indication, device type and size removed, method of removal, whether a new tube/stent was placed (and specifications), anesthesia/sedation, complications, and discharge condition.
