"notes" : "**Note 1:** Clinical assessment can be by physical examination or imaging. According to AJCC, \"ECS [extracapsular spread] can be diagnosed clinically by a matted mass of nodes adherent to overlying skin, adjacent soft tissue, or clinical evidence of cranial nerve invasion. Radiologic signs of ECS include amorphous, spiculated margins of a metastatic node and stranding of the perinodal soft tissue in previously untreated patients.\" (1)\n\n**Note 2:** Code the status of extracapsular extension assessed clinically for any involved regional lymph node(s) coded in Clinical N. Do not code extracapsular extension for any distant lymph node(s).\n\n**Note 3:** If nodes are involved clinically, and documentation of physical examination or imaging is available without a statement of extracapsular extension, use code 010.\n\n**Note 4:** If the only documentation is a reference to clinically involved nodes with no reference to extracapsular extension, use code 030.\n\n**Note 5:** If there is no information about clinical assessment of nodes, use code 999.",
