CPT® Code 50382

Removal (via snare/capture) and replacement of internally dwelling ureteral stent via percutaneous approach, including radiological supervision and interpretation

The procedure described by CPT® Code 50382 involves the removal and replacement of an indwelling ureteral stent through a percutaneous approach, which is a minimally invasive technique. This procedure is performed under radiological supervision, ensuring that the physician can visualize the internal structures of the kidney and ureter throughout the process. The term "indwelling ureteral stent" refers to a tube that is placed in the ureter to facilitate urine flow from the kidney to the bladder, often used in cases where there is an obstruction or other urinary tract issues. The use of a snare or capture device is critical in this procedure, as it allows for the effective retrieval of the existing stent. The percutaneous approach involves making a small incision in the skin, which minimizes trauma compared to open surgical methods. Radiographic guidance, including the use of contrast media and fluoroscopy, is essential for accurately navigating the anatomy and ensuring the correct placement of the stent. This procedure is typically indicated for patients who require stent replacement due to complications such as blockage, infection, or stent malfunction.
