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:** The specific location of the mesenteric nodes determines whether they are regional or distant. * If the specific location is not described, code in EOD Regional Nodes. **Note 3:** Porta hepatic nodes are recorded as distant for Body and Tail and should be coded in EOD Mets. * If the specific location for hepatic nodes is not described, code in EOD Regional Nodes. **Note 4:** Code 800 if regional lymph nodes are involved, but there is no indication which ones are involved.
