It should be an error to specify NA as a possible categorical variable level. So something like this:
NA
Alive;Dead;NA
should generate something like:
! Do not include the missing data code 'NA' as a level descriptor
rather than:
! Categories found in levels descriptor not used in data: 'NA'
This means no-one can call a level NA but that would be highly confusing!
