Used with permission of the American College of Surgeons, Chicago, Illinois. **Note 2:** *Schema Discriminator 1: Occult Head and Neck Lymph Nodes* is used to discriminate between Cervical Lymph Nodes and Unknown Primary Tumor of the Head and Neck, Ill-Defined Other and Soft Tissue Other when primary site is C760. **Note 3:** See the following schemas for the listed histologies * 8010, 8046, 8051-8052, 8070-8074, 8082-8084, 8121, 8140, 8147, 8200, 8310, 8430, 8450, 8480, 8525, 8550, 8562 (Schema Discriminator 1 Occult Head and Neck Lymph Nodes: 0,1): *Ill-defined Other* * 8941 (Schema Discriminator 1 Occult Head and Neck Lymph Nodes: 0, 1): *Soft Tissue Other* * 8710-8714, 8800-8934, 8940, 8950-9138, 9141-9582: *Soft Tissue Other* * 8935-8936: *GIST* * 9140: *Kaposi Sarcoma* * 9700-9701: *Mycosis Fungoides* **Note 4:** This schema applies when cervical lymph nodes are involved with cancer and the primary site is not known but is suspected to be in the head and neck, i.e., in one or more of the sites listed below. Cancer registry standard setters have agreed that such cancers should be coded to primary site code C760 to accommodate staging recommended by AJCC. * Lip: C000-C006, C008-C009 * Base of Tongue: C019 * Other and Unspecified Parts of Tongue: C020-C024, C028, C029 * Gum: C030-C031, C039 * Floor of Mouth: C040-C041, C048-C049 * Palate: C050-C052, C058-C059 * Other and Unspecified Parts of Mouth: C060-C062, C068-C069 * Parotid gland: C079 * Tonsil: C090-C91, C098-C099 * Oropharynx: C100-C104, C108-C109 * Nasopharynx: C110-C113, C118-C119 * Pyriform sinus: C129 * Hypopharynx: C130-C132. C138-C139 * Other and Ill-defined Sites in Lip, Oral Cavity and Pharynx: C140, C142, C148 * Nasal cavity: C300 * Middle ear: C301 * Accessory Sinuses: C310-C313, C318-C319 * Larynx: C320-C323, C328-C329 * Skin of lip: C440 * Skin of ear & external auricular canal: C442 * Skin of other & unspecified parts of face: C443 * Skin of scalp & neck: C444 **Note 5:** If the physician indicates that the metastatic cervical lymph node is most likely from a head and neck primary, then code primary site as C760. If the differential diagnosis includes non-head and neck sites, for example, the path report states metastasis to the cervical lymph node could be from a head and neck primary, lung primary, or gynecologic primary OR if there is no information indicating origin of primary tumor, then code primary site as C809 (Ill Defined Other)
