When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
Indicates that a seventh character is to be assigned to codes in a subcategory.
