Here's the answer to where he gets mental health, housing, etc services if he's off medicaid. They talk about a sliding scale but it's hard to imagine it could be much on a minimal income. Might be something like $5 per visit. These people would also help him get his meds.... either samples or with the pharma company programs. Still looking for reg med services.
This is the general concept re where he goes for regular medical care. You'd have to look at the income limit in the particular county. The 21% they suggest here is absurd, I suspect every county has a higher number. The point is to get the hospital/ clinic that would be in his area. They'll have some sort of indigent/ charity care program where there will be a sliding scale and they'll provide EVERY kind of care.
