CPT® Code 43278

Endoscopic retrograde cholangiopancreatography (ERCP); with ablation of tumor(s), polyp(s), or other lesion(s), including pre- and post-dilation and guide wire passage, when performed

The procedure described by CPT® Code 43278 refers to an Endoscopic Retrograde Cholangiopancreatography (ERCP) that includes the ablation of tumors, polyps, or other lesions within the biliary or pancreatic ducts. This advanced endoscopic technique involves the insertion of an endoscope through the esophagus, stomach, and into the duodenum, specifically targeting the ampulla of Vater, where the pancreatic duct and common bile duct converge. The procedure is designed to visualize and treat abnormalities in the biliary and pancreatic systems. During the ERCP, a catheter is introduced through the endoscope to cannulate the ampulla of Vater, allowing for the injection of contrast material. This contrast enhances the visibility of the biliary tract, gallbladder, and pancreas on imaging studies. The sphincter of Oddi is examined, and a guidewire is utilized to facilitate the advancement of the catheter into the biliary tract. The procedure may reveal strictures, filling defects, or other pathological changes that necessitate intervention. If lesions are identified, a balloon catheter can be employed to dilate the affected area, improving access for subsequent ablation. The ablation process involves the use of a laser device, which is carefully maneuvered through the endoscope to destroy the lesions in a controlled manner, ensuring complete removal. This comprehensive approach not only addresses the lesions but also includes pre- and post-dilation as needed, making it a critical procedure for managing biliary and pancreatic ductal pathologies.
