"notes" : "**Note 1**: Code only regional nodes and nodes, NOS in this field. Distant nodes are coded in CS Mets at DX.\n\n**Note 2**: Pericholedochal nodes are coded in CS Mets at DX for jejunum and ileum primaries.\n\n**Note 3**: The number of positive regional nodes is required to calculate the correct N category for this site. If information about the number of positive nodes is available, use code 100, 200, or 300. Use code 400 or 450 when the record identifies an N1 or N2 category but the specific information about the number of nodes involved is not available.",
"footnotes" : "- For CS Lymph Nodes codes 100-300 ONLY, when CS Lymph Nodes Eval is 1 or 9 and CS Coding System Original is before CS v02.05, the N category is assigned from the Lymph Nodes Clinical Eval Prior to V02.05 7th Table using Regional Nodes Positive and CS Site-Specific Factor 2. When CS Lymph Nodes Eval = 0, 5, OR (CS Lymph Nodes Eval is 1,9 and CS Coding System Original is at least V02.05), the N category is assigned from Lymph Nodes Clinical Eval V02.05 AJCC 7 Table using CS Site-Specific Factor 2. When CS Lymph Nodes Eval is 2, 3, 6, 8, or not coded, the N category for AJCC 7 staging is assigned as shown in the Lymph Nodes Pathologic Evaluation AJCC 7 Table Also Used When CS Lymph Nodes Eval is Not Coded using Regional Nodes Positive.",
