CPT® Code 47802

Deleted

The procedure described by CPT® Code 47802 refers to a U-tube hepaticoenterostomy, which is a surgical intervention performed to create a connection between the liver and the small intestine. This procedure is typically indicated in cases where there is a need to bypass obstructed bile ducts or to facilitate bile drainage from the liver directly into the intestine. The operation begins with a midline abdominal incision, allowing access to the liver, gallbladder, and bile ducts. During the surgery, the hilum of the liver is carefully dissected to expose the intrahepatic bile duct, where a U-tube is inserted. This U-tube serves as a conduit for bile, with one end placed within the bile duct and the other end extending into the small intestine, often through a jejunal Roux-en-Y limb. The procedure involves creating a separate enterotomy, which is an incision into the intestine, to allow the U-tube to exit the intestinal tract. Finally, stab incisions are made in the abdominal wall to secure both ends of the U-tube, ensuring that the system remains stable and functional post-operatively. This detailed approach is crucial for effective bile drainage and management of biliary obstructions.
