EOD Regional Nodes

Notes

**Note 1:** For head and neck schemas, this field includes all lymph nodes defined as Levels I-VII and Other by TNM. **Note 2:** If laterality of lymph nodes is not specified, assume nodes are ipsilateral. Midline nodes are considered ipsilateral. **Note 3:** 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. **Note 4:** For codes 100-700, use the list below for named regional lymph nodes. If the only information available is "regional lymph nodes, NOS" or "lymph nodes," code 800.
