Summary & Overview
CPT 47534: Percutaneous Image-Guided Biliary Drainage
CPT code 47534 represents percutaneous placement of a biliary drainage catheter with image guidance, an interventional radiology procedure used to relieve biliary obstruction and permit internal and external bile drainage. Nationally, this procedure is critical for managing obstructive jaundice, cholangitis, malignant biliary obstruction, and other conditions where endoscopic access is not feasible or has failed. It is commonly performed in hospital interventional radiology suites and outpatient IR facilities using ultrasound and/or fluoroscopy, and may include cholangiography.
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 47534 is used, typical sites of service, and the operational significance of the procedure. The publication provides benchmarks related to service utilization and payment patterns, highlights relevant policy updates affecting imaging-guided biliary drainage, and clarifies coding and billing considerations tied to procedure components and imaging use. The content is intended for billing professionals, practice administrators, interventional radiologists, and policy analysts seeking a national-level summary of clinical use and payer coverage considerations for CPT code 47534.
Billing Code Overview
CPT code 47534 describes the percutaneous placement of a catheter into the bile ducts to provide internal and external drainage of bile. The procedure is performed through the skin (percutaneous placement) and typically uses image guidance such as ultrasound and/or fluoroscopy to visualize anatomy and guide catheter placement. The service may include cholangiography when contrast dye is injected to image the bile ducts.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with obstructive jaundice secondary to a hilar cholangiocarcinoma presents with progressive pruritus, rising total bilirubin, and cholestatic liver enzyme elevation. Cross-sectional imaging demonstrates proximal biliary obstruction not amenable to endoscopic retrograde biliary drainage due to surgically altered anatomy. Interventional radiology schedules a percutaneous transhepatic biliary drainage (PTBD) procedure under conscious sedation.
The clinical workflow: pre-procedure review of imaging and coagulation status; informed consent discussion documenting indication and risks; ultrasound or fluoroscopic localization of dilated intrahepatic ducts; percutaneous needle access into a bile duct; guidewire and catheter placement; cholangiography with contrast to map the biliary tree; placement of an internal-external biliary drainage catheter to relieve obstruction and allow external bile collection and internal drainage; post-procedure imaging to confirm position; procedure note documenting use of image guidance, any cholangiography performed, catheter size, complications, and disposition.
Typical site of service: hospital interventional radiology suite or ambulatory surgical center with fluoroscopic and ultrasound capabilities. Service type: image-guided percutaneous biliary drainage with possible cholangiography.
