EOD Regional Nodes
This input is used for staging
Notes
**Note 1:** Code only regional nodes and nodes, NOS in this field. Distant nodes are coded in EOD Mets. **Note 2:** For Colon and Rectum ONLY, any unnamed nodes that are removed with a colon or rectal resection are presumed to be regional pericolic or perirectal lymph nodes and are included in the EOD Regional Nodes code 300 (pericolic for sites C180 - C189, C199 and perirectal for sites C199 or C209). This site-specific instruction applies only to colon and rectum tumors and was verified with subject matter experts.Default
