Carcinoid Tumor and Neuroendocrine Carcinoma of Appendix

Primary Site Histology Staging Type
C181 8153, 8240-8242, 8246, 8249 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

C181 Appendix **Note 1:** This schema is based on the UICC chapter *Appendix-Carcinoid,* pages 91-93. **Note 2:** Carcinoid tumor of the appendix is typically not reportable. * Use this schema if your institution collects this tumor as reportable by agreement. **Note 3:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Colon* chapter on page 94 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=94).
