I understand that treatments for many diseases can eat up money for newly unemployed, particularly if you were a financial idiot when you were rich. The story would be more plausible* if the story had been about him needing dialysis or something, which could eat up the profits from selling a mansion pretty quickly.

But it should not have taken 11 years to get a Huntington's diagnosis, never mind the years of symptoms while he still had money. Good thing the free clinic was so much smarter than everyone else.

* By "plausible" I don't mean the story isn't true (there is such a doctor), but I think there are some circumstances that put him in this crack that aren't the fault of the health care system.
