Malignant Melanoma of Anterior Tongue

Primary Site Histology Staging Type
C020-C023, C028-C029 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

C020 Dorsal surface of tongue, NOS C021 Border of tongue C022 Ventral surface of tongue, NOS C023 Anterior 2/3 of tongue, NOS C028 Overlapping lesion of tongue C029 Tongue, 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 *Anterior 2/3 of Tongue, Tip, Border and Tongue, NOS* chapter on page 38 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=38).
