CPT® Code 50434

Convert nephrostomy catheter to 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, via pre-existing nephrostomy tract

The procedure described by CPT® Code 50434 involves the conversion of a nephrostomy catheter to a nephroureteral catheter through a percutaneous approach. This procedure is essential for patients who require the restoration or maintenance of urine flow from the kidney to the ureter, particularly in cases where there are obstructions such as strictures, leaks, or fistulas. The nephrostomy catheter, which is typically placed to drain urine directly from the kidney, can be converted to a nephroureteral catheter to facilitate better drainage into the ureter. This conversion is performed using imaging guidance, such as ultrasound or fluoroscopy, to ensure accurate placement and to monitor the procedure's progress. The use of contrast dye during the procedure allows for visualization of the urinary tract, ensuring that the catheter is correctly positioned and functioning as intended. The procedure is conducted via a pre-existing nephrostomy tract, which simplifies the process and minimizes additional trauma to the patient. Overall, this procedure is critical for managing urinary flow issues and is performed under careful radiological supervision and interpretation to ensure optimal outcomes.
