"notes" : "**Note 1**: Assessment of clinically evident regional lymph nodes is based on information from the diagnostic workup. This might include: physical examination, imaging, diagnostic lymph node biopsy and exploratory surgery (without a resection). \n\n**Note 2**: In the rare instance that the number of clinically positive nodes is stated but a clinical N category is not stated, code 1-3 nodes as 100 (clinical N1), and 4 or more nodes as 200 (clinical N2).\n\n**Note 3**: If there is no diagnostic work-up to assess regional lymph nodes, use code 999. Do not apply the inaccessible nodes rule that presumes unmentioned nodes to be negative.",
