You may use a physician’s statement of the N category if this is the only information in the medical record. \n* If the size of the metastasis is not documented, determine the size of the largest involved lymph node as documented clinically\n* If the size of the lymph node(s) cannot be determined, assign N1\n* Do **not** code the size of any node(s) assigned in M (distant metastasis)\n\n**Regional lymph nodes**\n \n Aortic, NOS\n Lateral (lumbar)\n Para-aortic\n Periaortic\n Preaortic \n Retroaortic\n Pericaval, NOS\n Interaortocaval\n Paracaval\n Precaval\n Retrocaval\n Retroperitoneal, NOS\n Spermatic vein\n\n Regional lymph nodes, NOS\n Lymph nodes, NOS\n \n**Regional lymph nodes WITH previous scrotal or inguinal surgery** \n \n External iliac\n Inguinal nodes, NOS\n Deep, NOS\n Node of Cloquet or Rosenmuller (highest deep inguinal)\n Superficial (femoral)\n Pelvic, NOS",
