Summary & Overview
CPT 47539: Percutaneous Transhepatic Biliary Stent Placement
CPT code 47539 covers percutaneous transhepatic placement of a biliary stent through a new percutaneous access without placement of a separate drainage catheter. This image-guided interventional radiology procedure is used to restore or maintain bile duct patency in patients with obstructive biliary disease and often includes cholangiography, fluoroscopic and/or ultrasound guidance, balloon dilation, and stent manipulation. Nationally, the code is clinically important because it documents a definitive, minimally invasive treatment for biliary obstruction that affects hospital outpatient and inpatient interventional radiology workflows and reimbursement profiles.
Key payers considered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a compact overview of the procedure and its clinical role, plus what to expect in payer coverage patterns and coding practice for image-guided biliary stent placement. The publication also presents benchmarks for utilization and payment where available, highlights relevant policy updates that affect facility and professional billing, and offers clinical context that clarifies when CPT code 47539 applies versus other biliary access and drainage procedures. Data not provided in the input are noted as unavailable in the relevant sections.
Billing Code Overview
CPT code 47539 describes percutaneous transhepatic placement of a biliary stent through a newly created skin access tract without placement of a separate drainage catheter. The procedure may include cholangiography, fluoroscopic and/or ultrasound imaging guidance, balloon dilation of the bile ducts, and stent removal or exchange, and it includes all associated radiological supervision and interpretation.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with obstructive jaundice secondary to a malignant hilar cholangiocarcinoma presents with progressive pruritus, rising bilirubin, and cholestatic liver enzyme pattern. After cross-sectional imaging (CT/MRI) demonstrates intrahepatic biliary dilation and percutaneous access is favored over endoscopic access due to altered postoperative anatomy, the interventional radiology team schedules a percutaneous transhepatic biliary stent placement under conscious sedation. The procedure involves sterile prep and local anesthesia at the skin entry site, ultrasound or fluoroscopic guidance to access a dilated peripheral bile duct, catheterizing the biliary tree with cholangiography to define the stricture, traversing the malignant stenosis with guidewires, optional balloon dilation of the stricture, and deployment of an indwelling self-expanding metal stent across the obstructing lesion. No separate external biliary drainage catheter is left in place. The radiologist performs real-time fluoroscopic imaging and documents radiological supervision and interpretation. Typical postprocedure care includes monitoring in a recovery area for hemodynamic stability, assessment for bleeding, bile leak, or infection, and follow-up liver function tests. This percutaneous biliary stent placement is commonly performed in an ambulatory surgical center or hospital interventional radiology suite with appropriate fluoroscopy and ultrasound equipment.
