> My wife's a doctor who sees a lot of Medicare patients, and she warns all of them about Medicare Advantage. > > Don't do it. could you please explain in more detail why a move to medicare advantage from regular medicare is a bad decision? i'm asking because a family member is on regular medicare but is being pressured to move to an advantage plan. i would like some facts to help bolster his decision to stay on regular medicare (since i've also heard MA is a bad idea). thanks in advance.
