CPT® Code 47780

The CPT® Code 47780 refers to the surgical procedure known as Roux-en-Y anastomosis, specifically involving the extrahepatic biliary ducts and the gastrointestinal tract. This procedure is commonly utilized to address biliary obstruction, which can occur due to various conditions affecting the bile ducts. In simpler terms, a Roux-en-Y anastomosis is a type of surgical connection that reroutes bile flow from the liver directly into the small intestine, bypassing any obstructed areas of the bile duct. The procedure involves making an incision in the abdomen to access the liver, gallbladder, and the affected bile duct, as well as a segment of the small intestine, typically the jejunum. The surgical technique includes mobilizing and dividing a segment of the small intestine to create a new pathway for bile drainage. This is achieved by constructing a Roux-en-Y limb, which facilitates the anastomosis, or connection, between the small intestine and the bile duct. The goal of this procedure is to restore normal bile flow, thereby alleviating symptoms associated with biliary obstruction and improving the patient's overall digestive function.
