Notes

**Note 1**: Only include information from imaging and physical examination in this item. Do not include information on regional lymph nodes that is based on surgical observation or diagnostic lymph node biopsy. **Note 2**: Use code 400 if regional lymph nodes are involved clinically but there is no indication of the number of nodes involved. **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.
