Laryngeal Cartilage, Overlapping Lesion of Larynx, and Larynx, NOS (excluding Malignant Melanoma)

Primary Site Histology Staging Type
C323 8000-8713, 8800-9136, 9141-9582, 9700-9701 Summary Stage only
C328-C329 8000-8576, 8940-8950, 8980-8981 TNM 7 and Summary Stage
C328-C329 8577-8713, 8800-8939, 8951-8979, 8982-9136, 9141-9582, 9700-9701 Summary Stage only

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

C323 Laryngeal cartilage C328 Overlapping lesion of larynx C329 Larynx, NOS **Note 1:** This schema is based on the UICC chapter *Larynx,* pages 39-45. * Primary sites C328 and C329 are not listed in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met * Primary site C323 is not listed in this chapter of the UICC manual; however, it is included in this schema and not TNM staged (Summary Stage only) **Note 2:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Larynx: Overlapping lesion or NOS* chapter on page 148 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=148).
