CPT® Code 47540

Placement of stent(s) into a bile duct, percutaneous, including diagnostic cholangiography, imaging guidance (eg, fluoroscopy and/or ultrasound), balloon dilation, catheter exchange(s) and catheter removal(s) when performed, and all associated radiological supervision and interpretation; new access, with placement of separate biliary drainage catheter (eg, external or internal-external)

The procedure described by CPT® Code 47540 involves the placement of stent(s) into a bile duct through a percutaneous approach, which means that the procedure is performed through the skin. This intervention is primarily aimed at relieving obstructions in the bile duct, allowing bile to flow freely into the small intestine. The procedure includes several critical components: diagnostic cholangiography, which is an imaging technique used to visualize the bile ducts; imaging guidance, such as fluoroscopy or ultrasound, to assist in the accurate placement of the stent; and various procedural steps including balloon dilation, catheter exchanges, and catheter removals as necessary. The procedure also encompasses all associated radiological supervision and interpretation, ensuring that the placement is performed safely and effectively. A key aspect of this procedure is the creation of new access to the bile duct, which is achieved by placing a separate biliary drainage catheter, either external or internal-external, to facilitate bile drainage. This comprehensive approach is essential for managing bile duct obstructions and ensuring proper biliary function.
