Summary & Overview
CPT 47540: Percutaneous Biliary Stent and Drainage Catheter Placement
CPT code 47540 represents percutaneous placement of a biliary stent with placement of a separate drainage catheter, an image-guided interventional radiology procedure used to relieve biliary obstruction. This procedure is clinically significant nationwide because it provides definitive or palliative biliary decompression for patients with obstructive jaundice, malignant strictures, or benign biliary strictures when endoscopic approaches are not feasible or have failed.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent of the code, typical sites of service, and the procedural components that drive coding and billing: percutaneous access, cholangiography, fluoroscopic and/or ultrasound guidance, optional balloon dilation, catheter management (placement, removal, or exchange), and radiological supervision and interpretation.
The publication provides national benchmarks and practical context for payer coverage patterns, common billing modifiers and service-line placement, and policy updates that affect authorization and payment processes. Clinical context addresses indications and procedural elements that influence coding choices. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 47540 describes a percutaneous placement of a biliary stent with concurrent placement of a separate drainage catheter. The procedure involves creating a new percutaneous access (a small incision in the patient’s skin) to place a tubelike device that keeps the bile duct open and to position a drainage catheter.
The service typically includes intra-procedural cholangiography (contrast imaging of the bile ducts), imaging guidance with fluoroscopy and/or ultrasound, dilation of the ducts with a balloon catheter when performed, and removal and/or exchange of the catheter if part of the same encounter. Radiological supervision and interpretation are included as part of the service.
Service type: Image-guided interventional radiology procedure for biliary drainage and stent placement.
Typical site of service: Hospital outpatient department or interventional radiology suite (ambulatory surgical center or inpatient interventional radiology when clinically indicated).
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with obstructive jaundice secondary to malignant biliary stricture presents with progressive cholestasis, pruritus, and elevated bilirubin. Prior ERCP was unsuccessful due to tumor-related ampullary distortion. Interventional radiology performs a percutaneous transhepatic biliary stent placement with a separate external drainage catheter to relieve obstruction, restore bile flow, and allow biliary decompression. The workflow includes pre-procedure cross-sectional imaging review, informed consent, moderate sedation or monitored anesthesia care as appropriate, percutaneous transhepatic cholangiography to delineate ductal anatomy, ultrasound and fluoroscopic guidance for percutaneous access, tract dilation, placement of an internal biliary stent via the newly created tract, and placement of a separate external drainage catheter. The procedure may include balloon dilation of strictures, exchange or removal of existing catheters, and radiological supervision and interpretation. Post-procedure care includes imaging confirmation of stent position, monitoring for bleeding, bile leak, infection, and scheduling follow-up for catheter management or stent exchange.
