Not medicare but Medicaid. It was very hard for them/her to choose this route as they had always paid for everything or done without their entire married life. When it was all gone, including the deeds for their burial plots, Medicaid paid up for his nursing home care.
There is no shame in that jaded, I know it isn't your first choice but maybe if your sister can see how very serious you are at this point in time, she'll "step up".
I'd like to kick her where the sun doesn't shine!!!!

Where is Doody when we need her???
