Nasopharynx (excluding Malignant Melanoma)

Primary Site Histology Schema Discriminator: Nasopharynx/PharyngealTonsil Staging Type
C110, C112-C113, C118-C119 8000-8576, 8940-8950, 8980-8981 <Any value> TNM 7 and Summary Stage
C110, C112-C113, C118-C119 8577-8713, 8800-8939, 8951-8979, 8982-9136, 9141-9582, 9700-9701 <Any value> Summary Stage only
C111 8000-8576, 8940-8950, 8980-8981 010 TNM 7 and Summary Stage
C111 8577-8713, 8800-8939, 8951-8979, 8982-9136, 9141-9582, 9700-9701 010 Summary Stage only

If you are working with a site/histology that only summary stages and you need to directly code it, please use the SEER Summary Stage 2000 manual

Notes

C110 Superior wall of nasopharynx
C111 Posterior wall of nasopharynx (excluding pharyngeal tonsil)
C112 Lateral wall of nasopharynx
C113 Anterior wall of nasopharynx
C118 Overlapping lesion of nasopharynx
C119 Nasopharynx, NOS

Note 1: This schema is based on the UICC chapter Pharynx, pages 30-38.

  • Primary sites C118 and C119 are listed in the chapter heading but are not specified in the anatomic subsites in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met
  • Site-Specific Factor 25, Nasopharynx/PharyngealTonsil is used to discriminate between posterior wall of nasopharynx, staged with nasopharynx, and pharyngeal tonsil, staged with oropharynx. Both sites are coded to ICD-O-3 code C111

Note 2: The margin of the choanal orifices, including the posterior margin of the nasal septum, is included with the nasal fossa.

Note 3: In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the Nasopharynx chapter on page 62 of the SS2000 on-line manual.
