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, use the code that reflects the most specific statement about the number of nodes.\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.",
