Site-Specific Factor 3

Extranodal Extension of Regional Lymph Nodes

Notes

**Note 1:** Code the status of extranodal extension, whether assessed clinically or pathologically, of any involved regional lymph node(s). * Do not code extranodal extension for any distant lymph node(s) **Note 2:** A statement of the presence or absence of extranodal extension in a pathology report takes priority over clinical assessment. **Note 3:** If nodes are involved but the clinical documentation and/or pathologic documentation does not indicate extranodal extension, assign code 010 (no extranodal extension documented on the available reports). **Note 4:** If the only documentation is a reference to clinically or pathologically involved nodes with no reference to extranodal extension, assign code 030 (no physical examination/imaging report and/or no pathology report available).
