I can only see this working as a part of inheritance tax once an exemption amount has been passed. To give an example if an estate was over the exemption level of say $3mil then medicare would be repayed 100% and to the extent that the estate exceeded $3mil+medicare repayment then it would be taxed at the inheritance rate of 45%
Otherwise as stated earlier it would wipe out the estates of most working families.

Had a buddy that died of pancreatic cancer last year. His total treatments consisted of 2 1hr surgeries to put in stents, aprox 12days total stay in a county hospital, and a handful of spot radiation treatments done on an outpatient basis and his bills from the hospital, surgeon, oncologist and radiologist totalled $266,000. So far beyond ridiculous it's madening
