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 depth of stromal invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion. **Note 5**: Use codes 110-130 and 410-430 for tumors limited to the skin or subcutaneous/submucosal tissues of vulva and perineum only. Use code 602 for tumors involving fascia or musculature of vulva and perineum. **Note 6**: 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 450, 460, 470, and 810 as appropriate to code CS Extension based on a statement of T when no other extension information is available.Default
