CS Tumor Size

This input is used for staging

Notes

**Note**: The assignment of the T1 and T2 categories for neuroendocrine tumors (NET) of ampulla of Vater 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 991 and 992 as appropriate to code CS Tumor Size based on a statement of T when no other size information is available.
