CPT® Code 50694

Placement of ureteral stent, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy), and all associated radiological supervision and interpretation; new access, without separate nephrostomy catheter

The procedure described by CPT® Code 50694 involves the percutaneous placement of a ureteral stent, which is a medical device used to alleviate urinary obstruction. This obstruction may arise from various conditions such as kidney stones, tumors, or strictures that impede the normal flow of urine. The stent placement can also serve diagnostic purposes, allowing healthcare providers to assess urinary conditions, facilitate therapeutic interventions, or divert urine in cases of traumatic injury, leaks, fistulas, or hemorrhagic cystitis. The procedure is performed using imaging guidance, which may include ultrasound and/or fluoroscopy, to ensure accurate placement of the stent. The technique typically involves the use of a single or double needle approach, with careful insertion below the 12th rib to minimize complications such as puncturing the pleura. The process includes aspirating urine to confirm the correct location, injecting contrast dye for visualization, and threading a guidewire to position the stent appropriately within the urinary tract. The stent is designed to maintain urine flow from the kidney to the bladder, with specific configurations to ensure proper placement and function. This code encompasses all necessary imaging guidance, diagnostic procedures, and radiological supervision required during the stent placement process.
