"notes" : "**Note 1:** Histological examination of a selective neck dissection specimen will ordinarily include 6 or more lymph nodes. Histological examination of a radical or modified radical neck dissection specimen will ordinarily include 10 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0. When size is a criterion for pN classification, measurement of made of the metastasis, not of the entire lymph node. (1)\n\n**Note 2:** If laterality of lymph nodes is not specified, assume nodes are ipsilateral. Midline nodes are assigned as ipsilateral.\n\n**Note 3:** Size of the largest metastasis in a lymph node must be known to assign N. You may use a physician’s statement of the N category if this is the only information in the medical record.\n* If the size of the metastasis is not documented, determine the size of the largest involved lymph node as documented pathologically\n* If the size of the lymph node(s) cannot be determined, assign N1\n* Do not code the size of any node(s) assigned in M (distant metastasis)\n\n**Note 4:** The description of lymph nodes has been standardized across the head and neck schemas. All lymph node levels and groups listed here are assigned as regional nodes for TNM staging.\n\n **Level I**\n \n Level IA - Submental\n Level IB - Submandibular (submaxillary), sublingual\n**Level II - Upper jugular** \n\n Jugulodigastric (subdigastric)\n Upper deep cervical \n Level IIA - Anterior\n Level IIB - Posterior \n**Level III - Middle jugular**\n\n Middle deep cervical\n**Level IV - Lower jugular**\n\n Jugulo-omohyoid (supraomohyoid)\n Lower deep cervical \n Virchow node\n**Level V - Posterior triangle group**\n\n Posterior cervical\n Level VA - Spinal accessory \n Level VB - Transverse cervical, supraclavicular \n**Level VI - Anterior compartment group**\n\n Laterotracheal\n Paralaryngeal\n Paratracheal - above suprasternal notch\n Perithyroidal\n Precricoid (Delphian)\n Prelaryngeal\n Pretracheal - above suprasternal notch\n Recurrent laryngeal\n**Level VII - Superior mediastinal group (for other mediastinal nodes see M [distant metastasis])**\n\n Esophageal groove\n Paratracheal - below suprasternal notch\n Pretracheal - below suprasternal notch \n**Other groups**\n\n Cervical, NOS\n Deep cervical, NOS\n Facial\n Buccinator (buccal)\n Mandibular\n Nasolabial\n Internal jugular, NOS\n Parapharyngeal \n Parotid\n Infraauricular\n Intraparotid\n Periparotid\n Preauricular\n Retroauricular (mastoid)\n Retropharyngeal\n Suboccipital\n\n Regional lymph nodes, NOS\n Lymph nodes, NOS\n\n**Note 5:** For head and neck schemas, additional information about lymph nodes (size of involved nodes, extracapsular extension, levels involved, and location of involved nodes above or below the lower border of the cricoid cartilage) is coded in **Site-Specific Factors 1, 3-9**.\n\n**Note 6:** 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. \n* If the specific level cannot be determined, assign them as Level V nodes",
