CPT® Code 50387

Removal and replacement of externally accessible nephroureteral catheter (eg, external/internal stent) requiring fluoroscopic guidance, including radiological supervision and interpretation

The procedure described by CPT® Code 50387 involves the removal and replacement of an externally accessible nephroureteral catheter, which is a specialized tube designed to facilitate the drainage of urine from the kidney to the bladder. This catheter is typically used in patients who require urinary diversion or drainage due to various medical conditions affecting the urinary tract. The nephroureteral catheter is characterized by its flexible design, allowing it to navigate through the ureter and into the bladder, with a hub that exits the skin over the kidney, making it externally accessible. The procedure requires fluoroscopic guidance, which is a type of real-time imaging that allows the physician to visualize the catheter and surrounding structures during the intervention. This imaging is crucial for ensuring the accurate placement and function of the new catheter. The process includes the injection of contrast material to enhance visibility of the urinary tract, ensuring that the existing catheter can be safely removed and replaced with a new one. The procedure is comprehensive, involving careful manipulation of the catheter and guidewire, assessment of the stent's position, and securing the catheter to prevent dislodgement, all while ensuring that the urinary system remains patent and functional.
