EOD Regional Nodes
This input is used for staging
Notes
**Note 1:** **Regional nodes and nodes, NOS** * Code only regional nodes and nodes, NOS in this field. Distant nodes are coded in EOD Mets. **Note 2:** **Mesenteric nodes** * 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** * 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:** **CLINICAL AND PATHOLOGICAL codes** * This schema has lymph node codes that are defined as **CLINICAL** assessment only or **PATHOLOGICAL** assessment only. * **PATHOLOGICAL** assessment only codes (300, 700) are used when * Any microscopic examination of regional lymph nodes, includes * FNA, core biopsy, sentinel node biopsy or lymph node excision done during the clinical work up **AND/OR** * Lymph node dissection performed * Pathological codes 300, 700 take priority over codes 725, 775, 800 * **CLINICAL** assessment only codes (725, 775) are used when the **only** information on nodal involvement is based on **physical exam or imaging** * These codes are specifically for when there is no **microscopic confirmation** of regional lymph nodes (*Regional Nodes Positive = 98, 99*) * **Note:** Use code 300 if *Regional Nodes Positive is 01-90, 95* * Remaining codes (no designation of **CLINICAL** or **PATHOLOGICAL** only assessment) can be used based on clinical and/or pathological information * **Code 000** is used when there is no evidence of regional lymph nodes clinically **OR** lymph nodes are negative pathologically (*Regional Nodes Positive = 00, 98*) * **Code 800** is used when there are positive nodes (clinical or pathological), but the specific lymph nodes or number of positive nodes is unknown (*Regional Nodes Positive = 97*) * **Code 999** is used when the lymph node status is unknown and *Regional Nodes Positive = 99*Default
