CPT code 50432 covers image-guided percutaneous placement of a catheter into the renal pelvis to divert urine in the setting of obstruction of the renal pelvis or ureter, and may include nephrostogram or ureterogram imaging. This procedure is clinically important because it provides urgent or elective urinary decompression for obstructive uropathy, relieves pain and infection risk, and can be an essential bridge to definitive urologic management.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a national overview of clinical context and coding intent, typical sites of service, and common billing modifiers and considerations where available. The publication outlines benchmarks and policy-relevant points affecting coverage and reimbursement practices, summarizes where variations commonly occur across major payers, and highlights documentation elements important for procedural reporting.

This summary is intended for billing staff, interventional radiologists, urologists, and policy analysts seeking a concise reference on CPT code 50432, its clinical role in renal drainage procedures, and the payer landscape for this service.
