Collaborative Stage for TNM 7 - Revised 11/22/2010 [ Schema ]
CS Tumor Size
- Note 1: Code exact tumor measurements when available. Use codes 990-997 only if a specific measurement is not available.
- Note 2: The assignment of T categories for gastrointestinal stromal tumors (GIST) 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, 993, 996, and 997 as appropriate to code CS Tumor Size based on a statement of T when no other size information is available.
- Note 3: Codes 992-995 were obsolete in CS Version 2, V0201 and V0202. They are made active in V0203. Codes 996-997 are new for V0203. Tumors that now fall into one of these categories would have been coded as 011, 021, 051, 101, or 999 in V0201/V0202. Therefore cases with codes 011, 021, 051, 101, and 999 should be reviewed to determine if the cases should be recoded using codes 992-997.
