CPT® Code 50432

Placement of nephrostomy catheter, percutaneous, including diagnostic nephrostogram and/or ureterogram when performed, imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiological supervision and interpretation

The CPT® Code 50432 refers to the percutaneous placement of a nephrostomy catheter, a procedure that is essential for managing urinary obstructions. This procedure is typically indicated for patients experiencing blockages due to various conditions such as kidney stones, tumors, or strictures. It can also be utilized for diagnostic purposes to assess urinary conditions, provide access for therapeutic interventions, or divert urine in cases of traumatic injury, leaks, fistulas, or hemorrhagic cystitis. The procedure involves the use of imaging guidance, such as ultrasound or fluoroscopy, to ensure accurate placement of the catheter while minimizing risks. The nephrostomy catheter allows for the drainage of urine directly from the kidney, thereby relieving pressure and preventing further complications. The process may involve either a single or double needle technique, with careful attention to the anatomical structures to avoid complications such as puncturing the pleura. Overall, this procedure is a critical intervention in urology, facilitating both diagnostic and therapeutic management of urinary tract issues.
