As a practical matter, does it alter the medical care they get?

I think it may matter in terms of survivor benefits for those dying because of service connected disabilities.

Matters on their back pay and related benefits. From what I can see, if you are injured by an "enemy combatant" your status is different and Hasan was not declared an "enemy combatant".

So he was injured by "one of our guys". A step-up from workplace violence but not much.
