CPT 47532 Percutaneous Cholangiography Reimbursement | OpenPayer

Summary & Overview

CPT 47532: Percutaneous Cholangiography with New Access and Contrast Injection

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.

Billing Code Overview

CPT code 47532 describes a radiologically guided cholangiography with creation of a new access route and injection of contrast, using ultrasound and/or fluoroscopy to visualize the bile ducts. The procedure includes all radiological supervision and interpretation.

Service type: Percutaneous, image-guided diagnostic/interventional radiology procedure.

Typical site of service: Hospital outpatient department or ambulatory surgical center where fluoroscopy and ultrasound imaging are available.

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with suspected obstructive jaundice presents with progressive right upper quadrant pain, elevated liver function tests with a cholestatic pattern, and dilated intrahepatic bile ducts on ultrasound. The interventional radiology team schedules a percutaneous transhepatic cholangiography with creation of new access and injection of contrast to delineate the biliary anatomy and identify level of obstruction. Under moderate sedation in the radiology suite or hybrid operating room, ultrasound is used to target a safe transhepatic tract into a dilated peripheral bile duct. Fluoroscopy is used to confirm guidewire and catheter position. Contrast is injected for cholangiography to visualize strictures, stones, or leak. The procedure includes radiological supervision and interpretation, possible placement of a biliary drainage catheter or stent if indicated, and immediate post-procedure imaging to document catheter position and ductal decompression. Typical workflow steps: informed consent, preprocedural coagulation assessment, ultrasound-guided percutaneous duct puncture, tract dilation and catheter placement as needed, contrast injection under fluoroscopy for cholangiogram, image documentation and interpretation, and postprocedure monitoring for bleeding or bile leak. Typical site of service is the hospital-based interventional radiology suite or ambulatory surgical center with fluoroscopic capability.
