About 50432: Percutaneous nephrostomy catheter placement
Reports creation of new percutaneous renal access and placement of a nephrostomy catheter to drain the collecting system, with imaging guidance included.
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.

50432 billing questions
How is this different from placement of a nephroureteral catheter?
50432 places a nephrostomy catheter for drainage from the kidney. Use 50433 when the catheter is placed through new access and extends into the ureter.
Can the nephrostogram be billed separately?
A diagnostic nephrostogram or ureterogram performed as part of the catheter placement is included, as are imaging guidance and associated radiological supervision and interpretation.
When is 50430 or 50431 more appropriate?
Those codes describe an injection study for nephrostography or ureterography without the catheter placement reported by 50432. Choose based on whether access is existing or newly created and whether a catheter is placed.
Can modifier 50 be used when both kidneys are treated?
CMS identifies this as a bilateral procedure; when reported with modifier 50, payment is 150%. Documentation should support placement on both sides.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others at 50%. The 0-day global period includes same-day preoperative and postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
