anyone with insurance coverage through the va and/or medicare is not affected. you have insurance coverage and you don't need to change what you have. the marketplaces are not for people already covered by the programs you mentioned.
i have medicare but i'm also a veteran. . since i get most if not all of my medical care through them how will the aca affect my medical care? also what would be the best medical insurance for me to look into? for all veterans?
