CPT code 47532 represents a percutaneous, image-guided cholangiography in which the clinician creates a new access route and injects contrast into the biliary tree under ultrasound and/or fluoroscopic guidance. This code bundles radiological supervision and interpretation with the access and contrast injection and is used for diagnostic visualization or procedural planning of the bile ducts. Nationally, the code is relevant for hospitals and outpatient imaging centers that provide interventional radiology services for hepatobiliary conditions.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when CPT code 47532 is used, typical sites of service, and common billing considerations. The publication also outlines benchmark themes and payer coverage patterns, notes common modifiers associated with interventional radiology billing, and summarizes policy updates and reimbursement considerations affecting image-guided biliary procedures. The goal is to provide clinicians, billing professionals, and policy analysts with a clear, practical overview of the code’s clinical purpose and payment implications in the national marketplace.
