Unfortunately, Medicare patients are the majority of sick people who wind up in the hospital to begin with. There are some doctors, btw, that refuse to treat Medicare patients because the payments to doctors are also very low.
I'm sorry that you are disappointed in the care that you got. Do you think your expectations might be a little high? After all, you didn't get sick or die while you were there, and those are very good things.
Do you still have the patch?
