conditional default value

[Tim Johnson <suppressed>]

Hello All:
    (using MYSQL Ver 11.15 Distrib 3.23.41 
     for redhat-linux-gnu (i386) (RH 7.2))

I am importing text data (but in a numeric format).
  The customers wants 'N/A' in an empty field. 
Additionally:
  The customer wishes that if a field = '9999'
    the default value of 'N/A' be substituted.
Is this possible to do in MySQL? 
  Documentation?

Regards
