Summary & Overview
CPT 50387: Nephroureteral Catheter Removal and Replacement with Fluoroscopy
CPT code 50387 represents the fluoroscopically guided removal and replacement of an externally accessible nephroureteral stent or catheter, including radiological supervision and interpretation. This procedure is a commonly used image‑guided intervention to restore or maintain urinary drainage from the renal collecting system to an external collection device. Nationally, the code matters because it captures care delivered in hospital outpatient and interventional radiology settings and affects facility and professional billing workflows for urinary drainage management.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for nephroureteral catheter exchange, typical sites of service, and the operational implications for billing and documentation. The publication summarizes benchmarks where available, notes common modifier usage, and highlights policy or coverage considerations relevant to payers and providers. It offers clinicians, revenue cycle leaders, and policy staff a clear reference on what the code represents, how it is typically reported, and which aspects of care and coding warrant attention in national payer contexts. Data not available in the input is identified where applicable.
Billing Code Overview
CPT code 50387 describes the removal and replacement of an externally accessible nephroureteral stent/catheter using fluoroscopic guidance (live, real‑time X‑ray imaging). The procedure involves repositioning or exchanging a catheter that connects the renal pelvis and ureter to an external drainage system and includes radiological supervision and interpretation.
Service type: Image-guided interventional radiology procedure (nephroureteral catheter exchange/removal and replacement).
Typical site of service: Hospital outpatient department or interventional radiology suite where fluoroscopic imaging and radiological oversight are available.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with an existing externally accessible nephroureteral stent/catheter placed for urinary drainage after ureteral obstruction from malignancy, ureteral injury, or complex stone disease. The patient presents to an interventional radiology suite or ambulatory surgery center for a scheduled exchange because the external catheter is malfunctioning, infected, displaced, or has reached routine exchange interval. Preprocedure evaluation includes review of indication, allergy and anticoagulation status, recent imaging confirming catheter position, and consent. On the day of service the patient is positioned on a fluoroscopy table, local anesthesia and conscious sedation are provided as indicated, and the interventional radiologist uses live fluoroscopic guidance to remove the existing nephroureteral catheter and place a replacement catheter with confirmation of appropriate renal pelvis and ureteral drainage. The service includes radiological supervision and interpretation of imaging and immediate postprocedural evaluation prior to discharge. Typical sites of service are the hospital interventional radiology suite, outpatient ambulatory surgery center, or hospital outpatient department when inpatient status is not required.
