CPT® Code 47539

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, without placement of separate biliary drainage catheter

The CPT® Code 47539 refers to the procedure of placing stent(s) into a bile duct through a percutaneous approach. This procedure is essential for managing blockages in the bile duct, which can impede the flow of bile from the liver to the small intestine. The placement of a stent helps to keep the narrowed area of the bile duct open, facilitating the normal flow of bile and preventing complications associated with bile duct obstruction. The procedure includes several critical components: diagnostic cholangiography, which involves imaging the bile ducts to assess the blockage; imaging guidance, such as fluoroscopy or ultrasound, to ensure accurate placement of the stent; and various technical steps like balloon dilation, catheter exchanges, and catheter removals when necessary. Notably, this code specifies that the procedure is performed through a newly created access point, without the placement of a separate biliary drainage catheter. This distinction is important for accurate coding and billing, as it differentiates this procedure from others that may involve existing access points or additional drainage devices.
