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

C312 Frontal sinus C313 Sphenoid sinus C318 Overlapping lesion of accessory sinuses C319 Accessory sinus, NOS **Note 1:** Laterality must be coded for frontal sinus, C312 **Note 2:** TNM is not defined for this schema. If directly assigning Summary Stage 2000 (SS2000), use the *Accessory (Paranasal) Sinuses* chapter on page 134 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=134).
