My Mother lives with my sister. My sister owns the house herself, as well as another rental property. My mother does not own a house, She also does not have any $$ interest in my sisters house. And, my mother pays my sister $200.00 month towards expenses. My sister claims her as a dependent on her taxes. She is going into a nursing home shortly. Will my sister be responsible to repay my mothers nursing home expenses paid by Medicare because she claims my mother as a dependent? And will Medicare try to take either of my sisters properties?
