EOD Regional Nodes
Notes
**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in EOD Mets.
**Note 2:** Code 300 if there are satellite(s) or in-transit metastasis without regional lymph node involvement. Code 500 or 700 (based on number of nodes involved) if both satellite nodules/in-transit metastases and regional lymph nodes are present.
**Note 3:** Bilateral or contralateral nodes are classified as regional nodes for head, neck, and truncal tumors with bidirectional drainage to primary nodal basins, as shown on lymphoscintigraphy. Truncal tumors may also drain to both cephalad and caudal primary nodal basins as shown on lymphoscintigraphy.
* Clinical assessment of bilateral/contralateral or cephalad/caudal regional nodal involvement is required for tumors where lymphoscintigraphy is not performed
**Note 4:** Contiguous or secondary nodal basins are the next nodal drainage basins beyond the primary nodal basins and are coded as regional nodes.
