Size of Metastasis in Lymph Nodes
Notes
**Note 1**: If the only information on the size of the metastatic lymph node mass is the physician's assignment of the N category, assign code 010 for N1, 020 for N2, or 030 for N3. **Note 2**: If extranodal extension is not described on the pathology report or pathologic assessment of regional lymph nodes is not performed, assume extranodal extension is not present. **Note 3**: Do not code the size of any node coded in CS Mets at DX.Default
