"notes" : "**Note 1:** Histological examination of a regional lymphadenectomy specimen will ordinarily include 6 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0. (1)\n\n**Note 2:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis).\n\n**Note 3:** Bilateral nodes are classified as regional nodes for tumors with bidirectional drainage to primary nodal basins, as shown on lymphoscintigraphy. \n* Clinical assessment of bilateral regional nodal involvement is required for tumors where lymphoscintigraphy is not performed\n\n**Note 4:** Contiguous or secondary nodal basins are the next nodal drainage basins beyond the primary nodal basins. Secondary basins are regional for TNM staging.\n\n**Note 5:** In transit metastasis is defined as a tumor distinct from the primary lesion and located either between the primary lesion and the draining regional lymph nodes or distal to the primary lesion.\n* In transit metastasis is coded in N (regional lymph nodes)\n\n**Note 6:** Code isolated tumor cells (ITCs) as positive nodes.\n\n**Regional lymph nodes**\n* Head and Neck sites include bilateral or contralateral nodes\n\n**Lip (C440)**\n \n Cervical\n Facial, NOS \n Buccinator (buccal) \n Nasolabial \n Mandibular, NOS \n Parotid, NOS \n Infra-auricular \n Preauricular \n Submental \n Submandibular (submaxillary) \n \n**External ear/auditory canal (C442)**\n \n Cervical\n Mastoid (post-/retro-auricular) (occipital) \n Preauricular \n \n**Face, Other (cheek, chin, forehead, jaw, nose and temple) (C443)** \n \n Cervical\n Facial, NOS \n Buccinator (buccal) \n Nasolabial \n Mandibular, NOS \n Parotid, NOS \n Infra-auricular \n Preauricular \n Submental\n Submandibular (submaxillary) \n \n**Scalp (C444)** \n \n Mastoid (post-/retro-auricular) (occipital) \n Parotid, NOS \n Infra-auricular \n Preauricular \n Spinal accessory (posterior cervical)\n \n**Neck (C444)**\n \n Axillary \n Mandibular, NOS \n Mastoid (post-/retro-auricular) (occipital) \n Parotid, NOS \n Infra-auricular \n Preauricular \n Spinal accessory (posterior cervical) \n Submental \n Supraclavicular (transverse cervical) \n \n**Trunk (C445)** \n \n Axillary \n Cervical \n Internal mammary (parasternal)\n Femoral (superficial inguinal) \n Supraclavicular (transverse cervical) \n \n**Arm/Shoulder (C446)**\n \n Axillary \n Epitrochlear for hand/forearm \n Spinal accessory for shoulder \n \n**Leg/Hip (C447)**\n \n Femoral (superficial inguinal) \n Popliteal for heel and calf \n \n \n \n **Bidirectional nodal involvement (includes bilateral or contralateral nodes)**\n\n Upper Trunk: Femoral (or cephalad/caudal drainage from primary tumor) \n Lower Trunk: Axillary (or cephalad/caudal drainage from primary tumor)\n \n**Secondary nodal basin involvement (includes bilateral or contralateral nodes)**\n \n Head and Neck: Supraclavicular \n Arm/Shoulder: Supraclavicular \n Leg/Hip: Iliac \n All sites: Regional lymph node(s) in secondary nodal basins, NOS\n\n**Regional lymph node(s), NOS**",
