CPT® Code 43265

Endoscopic retrograde cholangiopancreatography (ERCP); with destruction of calculi, any method (eg, mechanical, electrohydraulic, lithotripsy)

Endoscopic retrograde cholangiopancreatography (ERCP) is a specialized medical procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions affecting the biliary and pancreatic ducts. This procedure is particularly significant for patients with obstructive jaundice, pancreatitis, or other biliary tract disorders. During ERCP, an endoscope—a flexible tube equipped with a camera and light—is inserted through the mouth, passing through the esophagus and stomach, and into the duodenum. The procedure specifically targets the ampulla of Vater, where the pancreatic duct and common bile duct converge. This location is critical for visualizing and accessing the ducts for further intervention. In the context of CPT® Code 43265, the procedure involves not only the visualization of these ducts but also the removal and destruction of gallstones (calculi) that may be obstructing the flow of bile or pancreatic juices. The destruction of these stones can be achieved through various methods, including mechanical means, electrohydraulic techniques, or lithotripsy, which utilizes shock waves to break the stones into smaller, passable fragments. The ability to perform both diagnostic and therapeutic actions during a single ERCP session makes it a valuable tool in managing biliary and pancreatic conditions effectively.
