Parotid Gland

Primary Site Histology Staging Type
C079 8000-8576, 8940-8950, 8980-8982 TNM 7 and Summary Stage
C079 8577-8939, 8951-8979, 8983-9136, 9141-9582, 9700-9701 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

C079 Parotid gland **Note 1:** This schema is based on the UICC chapter *Major Salivary Glands,* pages 54-57. **Note 2:** Laterality must be coded for this site. **Note 3:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Parotid Gland, Other Major Salivary Glands* chapter on page 54 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=54).
