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

C058 Overlapping lesion of palate C059 Palate, NOS C068 Overlapping lesion of other and unspecified parts of mouth C069 Mouth, NOS **Note 1:** This schema is based on the UICC chapter *Lip and Oral Cavity,* pages 25-29. * Primary sites C058, C059, C068, and C069 are not listed in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met **Note 2:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Other Mouth* chapter on page 50 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=50).
