Get a social worker involved. If you can find a decent one that is not overworked beyond belief.
Veteran?
There are lawyers who specialize in Seniors. Maybe a quick & free consult?

Many seniors today are maybe 2 or 3 major medical procedures away from bankruptcy without total insurance coverage. All this living longer has downsides.

edit: I have a f-i-l, 80yo, lives independently alone, 1000+ miles from relatives. Has bad back, bad cars, bad habits, minimal income. Lots of pain meds. Still thinks he can ride a Harley even following 2nd hand/wrist surgery. He is a timebomb waiting to create problems for many people. Stubborn old man syndrome run amok by tolerant indecisive step-children. It's messy, but can only get worse. I worked in senior assisted living my last 10 earning years - have seen the family disasters so many times it makes you cry. Private industry has no heart, the need so great, the cost so unrealistic. Even LTC insurance policies have limitations.

Good Luck.
