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

What 50432 covers

An interventional radiologist or urologist creates a new percutaneous route into the kidney and places a nephrostomy catheter to drain urine externally. This is commonly performed when obstruction, such as from a ureteral stone or tumor, requires drainage. Ultrasound or fluoroscopy guidance and a diagnostic nephrostogram or ureterogram, when performed as part of the placement, are included in the service.

Report this code for catheter placement through new access, not for imaging of an existing nephrostomy tract or exchange of a catheter already in place. The record should support the need for drainage, the new access and catheter placement, and the imaging used. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When bilateral procedures are reported with modifier 50, CMS pays 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
