Note 1: Code the status of extranodal extension whether assessed clinically or pathologically of any involved regional lymph node(s) coded in the CS Lymph Nodes field. Do not code extranodal extension in any nodes coded in CS Mets at DX field.
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 assessment 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 exam/imaging report and/or no pathology report available).
