Code D / 8955 SSA & Required Participant Notice

[BeanCounterBlues]

This may be a dumb question but I haven't been able to find a specific answer. If a particpant is coded A, and I prepare (as TPA) the necessary notice, when the same participant is coded D after distribution - do I have to give that participant another notice? EG is the notice required anytime a participant is SSA-reported, even if that means a participant may receive more than one notice? I don't see what purpose it serves to give a second notice after the Code D (that doesn't matter however; my goal is to do what the law requires). Thanks for any input.
