CPT® Code 47534

Placement of biliary drainage catheter, percutaneous, including diagnostic cholangiography when performed, imaging guidance (eg, ultrasound and/or fluoroscopy), and all associated radiological supervision and interpretation; internal-external

The CPT® Code 47534 refers to the procedure of placing a percutaneous biliary drainage catheter, specifically an internal-external type. This procedure is performed when there is a blockage in the bile ducts due to conditions such as stenosis, impacted stones, or tumors. The placement of the catheter allows for the drainage of bile, which is essential for maintaining proper liver function and preventing complications associated with bile duct obstruction. The procedure involves several steps, including the preparation of the skin, making an incision, and using imaging guidance techniques such as ultrasound or fluoroscopy to ensure accurate placement of the catheter. The internal-external biliary drainage catheter is designed to facilitate the drainage of bile both internally into the small intestine and externally through the skin, thereby alleviating the pressure caused by the obstruction. This procedure may also include diagnostic cholangiography, which involves the injection of contrast medium to visualize the bile ducts and confirm the location of the catheter. Overall, CPT® Code 47534 encompasses the comprehensive process of catheter placement, imaging guidance, and the necessary radiological supervision and interpretation associated with the procedure.
