CPT® Code 47511

Deleted

The CPT® Code 47511 refers to the procedure involving the introduction of a percutaneous transhepatic stent for the purpose of internal and external biliary drainage. This procedure is essential for patients who have obstructions in their bile ducts, which can lead to complications such as jaundice or cholangitis. The process begins with the preparation of the skin and making an incision at the designated site, typically located either over the right midaxillary line below the tenth rib for access to the right hepatic lobe or over the epigastrium for access to the left hepatic lobe. A small needle is then inserted through the skin into the bile duct, and contrast media is injected to confirm the needle's correct placement. Following this, a guidewire is introduced into the bile duct, allowing for the insertion of a coaxial exchange catheter. This catheter is used to navigate the bile duct, and any strictures present are dilated. In this procedure, a stent is placed to maintain patency in the bile duct, facilitating the drainage of bile into the small intestine. The stent is designed to have one end within the bile duct and the other exiting through the skin for external drainage. The procedure also includes the injection of additional contrast to verify that the bile duct remains open after the stent placement. It is important to note that the radiographic supervision and interpretation of the procedure are billed separately, ensuring that all aspects of the procedure are accurately documented and reimbursed.
