Notes

C039 Gum, NOS

Note 1: This schema is based on the UICC chapter Lip and Oral Cavity, pages 25-29.

  • Primary site C039 is not listed in this chapter of the UICC manual; however, it is 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 Gum (Gingiva), Retromolar area chapter on page 40 of the SS2000 on-line manual.
