**Note 1:** Physician statement of Lymph Nodes Size can be used to code this data item when no other information is available. **Note 2:** If the same largest involved node (or same level) is examined both clinically and pathologically, record the size of the node from the pathology report, even if it is smaller. * ***Example:*** Clinical evaluation shows 1.5 cm (15 mm) Level II lymph node, pathological examination shows Level II 1.3 cm (13 mm). Code 13.0. **Note 3:** If the largest involved node is not examined pathologically, use the clinical node size. **Note 4:** Do not code the size of any distant nodes.
