CPT® Code 47555

The procedure described by CPT® Code 47555 involves a biliary endoscopy performed percutaneously through a T-tube or another tract. This minimally invasive technique utilizes a flexible fiberoptic endoscope, which is a specialized instrument designed to visualize the bile ducts. During the procedure, the endoscope is carefully inserted through the T-tube or tract to inspect the bile ducts for any signs of disease or abnormalities. A critical aspect of this procedure is the identification and treatment of biliary duct strictures, which are narrowings that can impede the flow of bile. To address these strictures, a balloon catheter is introduced through a separate channel in the endoscope. The balloon is strategically positioned within the narrowed segment of the duct and inflated for a brief period, which helps to widen the stricture. After inflation, the balloon is deflated, and the narrowed segment is re-evaluated to assess the effectiveness of the dilation. This inflation and deflation process may be repeated multiple times to achieve optimal results. If multiple strictures are present, the procedure can be performed at different sites as needed. It is important to note that in this specific procedure, no stent is placed following the dilation, distinguishing it from similar procedures that may involve stent placement. After the dilation is completed, the endoscope is withdrawn, and the bile ducts are inspected once more for any potential signs of injury or complications resulting from the dilation process.
