CS Extension
This input is used for staging
Notes
**Note 1**: In the case of multiple simultaneous tumors, code the tumor with the greatest extension. **Note 2**: Skin ulceration does not alter the AJCC T category. **Note 3**: In-transit metastasis is coded in CS Lymph Nodes. **Note 4**: The assignment of the T1, T2, and T3 categories for Merkel cell carcinomas is based on tumor size. A physician's statement of the T category may be used to code both CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently; for example, the record may document size but not extension. Use codes 310, 320, 330, and 810 as appropriate to code CS Extension based on a statement of T when no other extension information is available.Default
