It doesn't sound like he's hospitalized right now. (Medicare covers 90 days of hospitalization per benefit period, with a lifetime reserve of 60 days that does run out.)

That's true AFAIK. The campaign is supposed to deal with his after-hospitalization expenses.

The hospitalization part of Medicare has no cost -- all you have to do is be in the right age group and sign on the dotted line. The cost segment of Medicare deals with medical procedures other than a hospital visit.

As far as I understand it, the present campaign is described as being for his after-hospitalization expenses.
