VALIDATION: --TERM / --DECOD

Is there a compliance check that ensures the same --TERM value is mapped to the same coded value in --DECOD?  I did see there were checks for --PTCD and --DECOD, but nothing I could find in the Validation Rules for --TERM / --DECOD relationship.  I know it seems obvious that the same value should be coded to the same decoded value, which I was surprised that was not a check.

Thanks in advance for any input!
