Site-Specific Factor 5
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 distant lymph node(s).Default
