If I claim a parent as a dependent, does it affect their PACE, Medicare, etc. benefits in any way?

I've met all the requirements to claim my mother and step-father as dependents. I just want to make sure if I claim them that it does not affect any social programs they use, like PACE for senior prescriptions, Medicare, LIHEAP, etc. I assume those programs are based on their income, but I want to make sure if I do claim them as dependents that they will still keep the same benefits related to these programs.
