CPT® Code 50433

Placement of nephroureteral catheter, 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

The CPT® Code 50433 refers to the percutaneous placement of a nephroureteral catheter, which is a specialized procedure aimed at addressing urinary obstructions. This obstruction may arise from various causes, including the presence of stones, tumors, or strictures within the urinary tract. The procedure is also utilized for 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 placement of the catheter is performed using imaging guidance, such as ultrasound and/or fluoroscopy, to ensure accurate positioning and minimize complications. The procedure may involve either a single or double needle technique, with careful insertion below the 12th rib to avoid damaging surrounding structures, such as the pleura. The process includes aspirating urine to confirm the correct location, injecting contrast dye for visualization, and ultimately placing a self-restraining catheter to maintain access to the urinary system. This code encompasses all aspects of the procedure, including the imaging guidance and the necessary radiological supervision and interpretation, ensuring comprehensive care for patients experiencing urinary tract issues.
