hi..
If you are sure your brother is covered by medical assistance, then the ER trip, as well as ambulance costs and testing should be covered. I would check with the hospitals billing department to make sure they submitted those charges to medical assistance. I know there have been times where I have been taken in by ambulance and I was not asked for my card, or just dont remember what happened, and I received a bill a few weeks later.

As far as disability goes, its important for him to see the neuro, and any other doctor if he has emphysema. The more visits he has documented the better his chances of getting approved for disability. I know it can be hard hearing what the docs have to say, but he really needs to have things documented so he can get the help he needs.

Take care !
