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

C340 Main bronchus C341 Upper lobe, lung C342 Middle lobe, lung C343 Lower lobe, lung C348 Overlapping lesion of lung C349 Lung, NOS **Note 1:** This schema is based on the UICC chapter *Lung,* pages 138-146. * Primary sites C348 and C349 are listed in the chapter heading but are not specified in the anatomic subsites in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met **Note 2:** Laterality must be coded for this site (except carina). **Note 3:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Lung* chapter on page 154 of the [SS2000 on-line manual](http://seer.cancer.gov/tools/ssm/SSSM2000-122012.pdf#page=154).
