EOD Regional Nodes

This input is used for staging

Notes

**Note:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in EOD Mets. **The following lymph nodes are regional for Head and Neck tumors** **Level I** Level IA - Submental Level IB - Submandibular (submaxillary), sublingual **Level II - Upper jugular** Jugulodigastric (subdigastric) Upper deep cervical Level IIA - Anterior Level IIB - Posterior **Level III - Middle jugular** Middle deep cervical **Level IV - Lower jugular** Jugulo-omohyoid (supraomohyoid) Lower deep cervical Virchow node **Level V - Posterior triangle group** Posterior cervical Level VA - Spinal accessory Level VB - Transverse cervical, supraclavicular **Level VI - Anterior compartment group** Laterotracheal Paralaryngeal Paratracheal - above suprasternal notch Perithyroidal Precricoid (Delphian) Prelaryngeal Pretracheal - above suprasternal notch Recurrent laryngeal **Level VII - Superior mediastinal group (for other mediastinal node(s) see EOD Mets)** Esophageal groove Paratracheal - below suprasternal notch Pretracheal - below suprasternal notch **Other groups** Cervical, NOS Deep cervical, NOS Facial - Buccinator (buccal) - Mandibular - Nasolabial Internal jugular, NOS Parapharyngeal Parotid - Infraauricular - Intraparotid - Periparotid - Preauricular Retroauricular (mastoid) Retropharyngeal Suboccipital
