Cholangiography and pancreatography are specialized radiological procedures aimed at visualizing the bile ducts and pancreatic duct, respectively. These procedures are essential for diagnosing conditions such as stones, inflammation, or obstructions within these ducts. Cholangiography focuses on the bile ducts, which transport bile from the liver and gallbladder to the small intestine, while pancreatography examines the pancreatic duct, which carries digestive enzymes from the pancreas. Typically, these procedures are performed during biliary surgery or in the post-operative setting through a catheter that has already been placed. After the removal of the gallbladder, a small catheter is inserted into the cystic duct, which is responsible for draining bile from the gallbladder into the common bile duct. The pancreatic duct merges with the common bile duct just before entering the duodenum at the ampulla of Vater. The imaging process utilizes x-ray technology, which employs indirect ionizing radiation to capture images of the internal structures of the body. This method is effective because different tissues absorb x-rays to varying degrees based on their density and composition, allowing for the creation of detailed two-dimensional images. To enhance the visibility of the anatomical structures and their functions, a contrast material is injected into the ducts. This contrast agent improves the definition of the images, making it easier to identify any abnormalities. The entire procedure is conducted under the direct supervision of a radiologist, who oversees the injection of the contrast material and interprets the resulting images, providing critical information to the surgeon regarding the condition of the bile and pancreatic ducts. The specific CPT® code 74305 is designated for reporting the radiological supervision and interpretation of cholangiography and/or pancreatography when these procedures are performed post-operatively through an existing catheter or T-tube.
