Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code CS tumor size 992 [stated as greater than 1 cm] and SSF6 code 020.
The September 2006 revision to the CS Tumor Size table now lists the 992-995 range codes as "greater than ___ cm."
It is better to code the invasive size than the entire size of the tumor. In the TNM mapping, this would more accurately portray the tumor as T1c rather than T2.
