Collaborative Stage

Note : The assignment of T1 and T2 categories for soft tissue sarcomas 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 995 and 996 as appropriate to code CS Tumor Size based on a statement of T when no other size information is available.
