Malignant Melanoma of Floor of Mouth

Primary Site Histology Staging Type
C040-C041, C048-C049 8720-8790 TNM 7 and Summary Stage

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

C040 Anterior floor of mouth C041 Lateral floor of mouth C048 Overlapping lesion of floor of mouth C049 Floor of mouth, NOS **Note 1:** This schema is based on the UICC chapter *Malignant Melanoma of Upper Aerodigestive Tract,* pages 51-53. **Note 2:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Floor of Mouth* chapter on page 42 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=42).
