Note 1 Physician statement of other head and neck lymph node involvement can be used to code this data item when no other information is available.

Note 2 Head and Neck Lymph Node Involvement is coded in the following data items

LN Head and Neck Levels I-III (NAACCR Data Item #3876)
LN Head and Neck Levels IV-V (NAACCR Data Item #3877)
LN Head and Neck Levels VI-VII (NAACCR Data Item #3878)
LN Head and Neck Other (NAACCR Data Item #3879)

Note 3 Code the presence or absence of lymph node involvement for the "other" group.

For more information on the other head and neck lymph nodes, see AJCC 8th edition, Chapter 5 Staging Head and Neck Cancers, Table 5.1

Note 4 Pathological information takes priority over clinical.

Note 5 If involved regional node levels are documented as a range, and/or if the involved nodes overlap multiple levels, code 7.

Note 6 If information is available on some nodes, but the others are unknown, code what is known.

*Example* Multiple lymph nodes involved, preauricular documented, but the other levels not mentioned. Code 4 to indicate preauricular involvement.
