In the absence of other tumor involvement (lymph node involvement or distant metastasis), code the lobe or segment involvement as follows: If multiple lobes (such as the Caudate lobe and the Left Lobe) are involved, code 2 (Regional). If multiple segments (such as 5 and 6 in the right lobe) in the same lobe are involved, this would be multiple tumors within one lobe, code 1 (Localized). * Caudate lobe: Segment 1 * Quadrate lobe: Segment 4b * Left lobe: Segments 2, 3, 4a * Right lobe: Segments 5, 6, 7, 8
