CS Tumor Size
This input is used for staging
Notes**Note 1**: Code the specific tumor size to the nearest millimeter (mm) as documented in the medical record. Use codes 990-996 only if a specific measurement is not available. **Note 2**: The assignment of T1, T2, and T3 categories for tumors of the lip and oral cavity is based on tumor size. A physician's statement of the T category may be used to code 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, other than the physician's statement of the T category. Use codes 992, 994, and 995 as appropriate to code CS Tumor Size based on a statement of T when no other size information is available.
