My mom lives independent now but I take care of her needs since she is legally blind and deaf.. I also have disabled son confined in wheelchair. It has become too difficult for me to run back and forth. We thought we could take what savings we both have left and buy a handicapped assessable home together. My question is, what happens if my mom needs more help than I can give eventually and needs to go into a nursing home on her medicare since she won't have much money left ..will I be held responsible to repay Medicare when she passes?
