Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 50434 covers

An interventional radiologist or other qualified physician uses an existing percutaneous kidney access to redirect a nephrostomy catheter through the ureter, typically positioning its distal end in the bladder. This changes the drainage route from a catheter confined to the kidney to one that traverses the ureter. Fluoroscopic or other imaging guidance and a contrast study of the collecting system or ureter may be part of the procedure.

Report 50434 when an existing nephrostomy catheter is converted; documentation should identify the prior access and catheter, the route established, and the final catheter position. Imaging guidance, associated radiological supervision and interpretation, and a nephrostogram or ureterogram when performed are included. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures at 50%. For bilateral conversion, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
