DESCRIPTION

Contains the numeric representation for the AJCC 7th edition “M” and is derived from CS coded fields using the CS algorithm. This numeric representation is referred to as the storage code and its associated label is referred to as the display code. The display code should be used for display on the screen and in reports.

LEVELS
