Clinical Assessment of Regional Lymph Nodes
Notes
**Note 1**: Clinically evident regional lymph nodes are based on information from the diagnostic workup. This might include: physical examination, imaging, diagnostic lymph node biopsy and exploratory surgery (without a resection). **Note 2**: In the rare instance that the number of clinically positive nodes is stated but a clinical N category is not stated, code 1-2 nodes as 100 (N1), 3-6 nodes as 200 (N2), and 7 or more nodes as 300 (N3). **Note 3**: If there is no diagnostic workup to assess regional lymph nodes, use code 999. Do not apply the inaccessible nodes rule that presumes unmentioned nodes to be negative.Default
