I can't answer your question in particular, but I wanted to let you know that all policies are different. It's really hard to tell what is covered and what isn't from what you stated alone. I would suggest asking your father to reach out to his hr department and see if he can get the policy information delivered to him. I dealt with Aetna in the past and they are very ambiguous about what they cover. It's mainly up to the employer if they cover these sorts of things, so I would check and see what's available.
