i would call your insurer to question this visit. it sounds very unusual and i would worry that it's not actually a representative of your insurance company but a scammer. particularly if you're covered by medicare this is a huge problem. never give out your medicare bank account or any other personal information.
my insurance company wants to send a doctor to my home to evaluate my wife and me. why? . they have never done this before. my wife has ra. can they cancel her before obamacare?
