Notes

**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.
