BileDuctsDistal

CS Extension

Note 1: Distal bile duct tumors arise between the junction of the cystic duct-bile duct and the ampulla of Vater. The classification includes tumors developing in congenital choledochal cysts and tumors arising in the intrapancreatic portion of the common bile duct.Note 2: Involvement within the porta hepatis is coded according to the structures involved: portal vein, common hepatic artery, and common hepatic duct.
