CPT® Code 43276

Endoscopic retrograde cholangiopancreatography (ERCP); with removal and exchange of stent(s), biliary or pancreatic duct, including pre- and post-dilation and guide wire passage, when performed, including sphincterotomy, when performed, each stent exchanged

The procedure described by CPT® Code 43276 refers to Endoscopic Retrograde Cholangiopancreatography (ERCP) with the removal and exchange of stent(s) in the biliary or pancreatic duct. This complex procedure involves the use of an endoscope, which is a flexible tube equipped with a camera and light, allowing the physician to visualize the internal structures of the digestive system. The endoscope is carefully passed through the esophagus, stomach, and into the duodenum, specifically targeting the ampulla of Vater, where the pancreatic duct and common bile duct converge. This area is critical for the drainage of bile and pancreatic juices into the small intestine. During the procedure, a smaller catheter is introduced through the endoscope to cannulate the ampulla of Vater, enabling the injection of contrast material. This contrast allows for detailed imaging of the biliary tract, gallbladder, and pancreas, facilitating the identification of any obstructions or abnormalities. The sphincter of Oddi, which regulates the flow of bile and pancreatic secretions, may be inspected and incised to facilitate the removal of existing stents or the placement of new ones. The procedure also includes the use of a guidewire to assist in navigating to the site of the stent within the duct. Once the existing stent is removed, the physician may perform balloon dilation at the site of any strictures to ensure adequate passage for bile or pancreatic secretions. Following this, a new stent is positioned and expanded to maintain patency in the duct. The entire process is meticulously monitored through imaging to confirm the successful placement and function of the stent. If multiple stents are exchanged during the procedure, the code 43276 is reported for each stent exchanged, reflecting the complexity and thoroughness of the intervention.
