I feel your pain, I had similar dealings with the deaths of 4 immediate family.

Another trick Dartmouth tried on my is that they delayed billing my insurance company until it was too late, then came at ME For payment since they couldn't collect from the insurance. How is their terrible billing setup MY problem?

Or when they bill me for an 'out of newtwork' service IN THEIR OWN HOSPITAL because the DR reading an MRI was not in network and I didn't get prior authorization.

Medicare will get their pound of flesh in the end. The only way around it really is to 'use up' the assets in some other way before Medicare gets their slice, but it may be too late for that.
