Interventional radiology

About 50431: Antegrade urinary contrast study, new access

Reports a contrast study of the renal collecting system and ureter performed through newly established percutaneous access to assess drainage, patency, or obstruction.

An antegrade nephrostogram or ureterogram traces contrast from the kidney’s collecting system down the ureter. Code 50431 identifies a diagnostic study reached by creating new percutaneous access, rather than injecting contrast through an already-present nephrostomy catheter. An interventional radiologist or urologist typically uses ultrasound or fluoroscopy to guide access, injects contrast, and interprets the images in an interventional radiology suite or hospital procedure room. The study can help clarify suspected obstruction, a leak, or impaired drainage.

Report 50431 when the new access is used for the contrast examination and a catheter placement service does not account for the work. Nephrostomy or nephroureteral catheter placement codes include the diagnostic contrast study when performed, so do not separately report 50431 for that included imaging. Document the indication, newly obtained access, contrast examination, findings, and laterality. CMS assigns a 0-day global period, including same-day preoperative and postoperative care. For bilateral service, modifier 50 is paid at 150%. In a session with multiple procedures, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is barred; co-surgeon and team-surgery billing are not permitted.
