CS Lymph Nodes: Hard Palate

Note 1: For head and neck schemas, this field includes all lymph nodes defined as Levels I-VII and Other by AJCC.The complete definitions are provided in the General Instructions.

Note 2: For head and neck schemas, additional information about lymph nodes (size of involved nodes, extracapsular extension, and levels involved) is coded in Site-Specific Factors 1-6.

Note 3: If laterality of lymph nodes is not specified, assume nodes are ipsilateral.Midline nodes are considered ipsilateral.

Note 4: For head and neck cancers, if lymph nodes are described only as "supraclavicular", try to determine if they are in Level IV (deep to the sternocleidomastoid muscle, in the lower jugular chain) or Level V (in the posterior triangle, inferior to the transverse cervical artery) and code appropriately.If the specific level cannot be determined, consider them as Level V nodes.

* For codes 10-12, 20-22, 30-32, 40-42, 50-52, and 80 ONLY, the N category is assigned based on the value of Site-Specific Factor 1, Size of Lymph Nodes, using the extra table, Lymph Nodes Size Table for this site.
