Liver

CS Extension

Note 1: In codes 390, 400, and 440, "multiple (satellite) nodules/tumors" includes satellitosis, multifocal tumors, and intrahepatic metastases.
Note 2: Major vascular invasion (code 630) is defined as invasion of the branches of the main portal vein (right or left portal vein, not including sectoral or segmental branches) or as invasion of one or more of the three hepatic veins (right, middle, or left). Invasion of hepatic artery or vena cava is coded to 660.
