Notes
**Note 1:** Involvement of inguinal, pelvic, or external iliac lymph nodes **WITHOUT** previous scrotal or inguinal surgery prior to presentation of the testis tumor is coded in M (distant metastasis), as distant lymph node involvement. **Note 2:** Size of the largest metastasis in a lymph node must be known to assign N. You may use a physician’s statement of the N category if this is the only information in the medical record. * If the size of the metastasis is not documented, determine the size of the largest involved lymph node as documented clinically * If the size of the lymph node(s) cannot be determined, assign N1 * Do **not** code the size of any node(s) assigned in M (distant metastasis) **Regional lymph nodes** Aortic, NOS Lateral (lumbar) Para-aortic Periaortic Preaortic Retroaortic Pericaval, NOS Interaortocaval Paracaval Precaval Retrocaval Retroperitoneal, NOS Spermatic vein Regional lymph nodes, NOS Lymph nodes, NOS **Regional lymph nodes WITH previous scrotal or inguinal surgery** External iliac Inguinal nodes, NOS Deep, NOS Node of Cloquet or Rosenmuller (highest deep inguinal) Superficial (femoral) Pelvic, NOSNAACCR Item
