LN Size
Lymph Nodes Size
Description
Lymph Nodes Size records diameter of the involved regional lymph node(s) with the largest diameter of any involved regional lymph node(s). Pathological measurement takes precedence over a clinical measurement for the same node. This data item is used to code the size of involved lymph nodes and is recorded in millimeters.Notes
**Note 1:** **Physician Statement** * Physician statement of Lymph Nodes Size can be used to code this data item when no other information is available. **Note 2:** **Clinical vs Pathological size** * If the largest involved node is not examined pathologically, use the clinical node size. * If the same largest involved node (or same level) is examined both clinically and pathologically, record the size of the node from the pathology report, even if it is smaller. * *Example*: Clinical evaluation shows 1.5 cm (15 mm) Level II lymph node, pathological examination shows Level II 1.3 cm (13 mm). * Code 13.0. **Note 3:** **Regional vs. distant nodes** * Do not code the size of any distant nodes.| Code | Description |
