CPT 47541 Percutaneous Biliary Access Reimbursement | OpenPayer

Summary & Overview

CPT 47541: Percutaneous Biliary Access with Diagnostic Cholangiography

CPT code 47541 documents a percutaneous transhepatic biliary access procedure performed with ultrasound and/or fluoroscopy when initial endoscopic biliary access fails. Nationally, the code captures care for patients requiring alternative biliary drainage or diagnostic cholangiography and is relevant to hospital outpatient and interventional radiology service lines. It is used to report both the technical image-guided access and the radiological supervision and interpretation associated with the procedure.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for percutaneous biliary access, typical sites of service, and payer coverage considerations. The publication highlights benchmarks for utilization and reimbursement where available, summarizes relevant coding and billing considerations, and places the procedure in clinical workflows for patients with obstructive biliary disease when endoscopic approaches are unsuccessful. Data not available in the input will be noted as such in specific sections.

Billing Code Overview

CPT code 47541 describes a percutaneous transhepatic biliary drainage procedure performed when endoscopic biliary access is unsuccessful. The provider obtains new percutaneous access through the biliary tract and into the small intestine using ultrasound and/or fluoroscopy to guide the approach. The procedure may include diagnostic cholangiography by injecting contrast into the bile ducts and comprises all associated radiological supervision and interpretation.

Service type: Image-guided interventional radiology procedure for biliary access and drainage

Typical site of service: Hospital outpatient department or interventional radiology suite, with potential performance in settings equipped for fluoroscopic and ultrasound guidance such as tertiary care centers.

Clinical & Coding Specifications

Clinical Context

A 64-year-old patient with obstructive jaundice secondary to choledocholithiasis undergoes an attempted endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic access to the bile duct and duodenum cannot be achieved due to altered anatomy from prior gastric bypass and a tight periampullary stricture. The interventional radiology team is consulted for percutaneous transhepatic biliary access and creation of a biliary-enteric fistula into the small intestine under ultrasound and fluoroscopic guidance (47541).

Clinical workflow: the patient is evaluated pre-procedure (review imaging, coagulation status, informed consent). In the IR suite, ultrasound is used to localize a dilated intrahepatic duct; fluoroscopy guides needle access through the liver into the biliary tree and across the obstruction into the small bowel to create a percutaneous biliary-enteric tract. Contrast may be injected for diagnostic cholangiography to define ductal anatomy. The procedure includes radiological supervision and interpretation, placement of drains or internal-external biliary stents as indicated, and post-procedure monitoring for complications such as bleeding, bile leak, or infection. Documentation includes indication, attempts at endoscopic access, imaging findings, approach, devices placed, and interpretation of cholangiography.
