As I understand it, everyone's medicare cost
is different, for part B, dependent upon when they qualified. As I have been insured by my ex husband's employer, I haven't needed it. They cut me off with no notice, nothing in writing, no phone call, nothing. When already qualified for part B, they are supposed to get it started as of the next first of the month once you request it, but they are overwhelmed and I and I was told it realistically takes 2-3 months.
