My mother suffered a stroke in February quite a few years ago while working. After that, she was unable to work. It took over a year for her to get Social Security disability payments approved.
About 6-7 years later, she experienced another series of strokes, which landed her in a nursing home. She was unable to speak, was paralyzed on her left side, and required a feeding tube.
The Medicare reps said they would pay the first 3 months of care in a nursing facility -- or for costs of caring for her at home. Then, if she remained in the home/on home care due to the same health event, she'd have to pay herself. Once her assets dwindled to $2,000 (basically, they look back 5 years and count any assets you owned, even if you sold them, to keep people from transferring their assets to friends or family in order to not spend them on healthcare), they would pick up the tab again under Medicaid.
Medicare said BEFORE SHE WAS CHECKED INTO THE NURSING FACILITY that the place was approved for Medicare reimbursement. When it came time for the facility to bill Medicare, they changed their mind. Medicare claimed the facility was classified a "Professional Nursing Care Facility." Appeals did nothing, and they let everyone know that pre-approval in no way guarantees approval for reimbursement.

What's puzzling is, she can't be the first person in that facility that tried use Medicare. Something fishy if she was denied and no one before her was. I have a feeling it's one of those "Medicare changed the rules" and she was caught up in the transition" situations.
So, Medicare wound up paying zero of the over $21,000 nursing home cost between February and June when she finally passed.
So, yeah. If you have ANYTHING the gov't can take, they'll take it. Gotta pay your fair share. Ain't nothing from the government "free".
This is what Medicare for all will look like. No matter what they promised, what rules were in place, or what others have received in benefits, it won't take long before the economy, tax revenues or higher costs force them to pull the rug out from under everyone who was counting on it.
