 We asked seniors how to prevent Medicare scams. My best advice, if you get a phone call, do not talk to the person. These people are well-trained. Don't talk to them. They don't know me. They're just trying to scam me. Don't be fooled. Hang up. Don't hang up. Never give out your Medicare number. They want to get your number and put in a false claim. If I get a call from someone, I don't pick up the phone. And should I pick up the phone and ask for information, then I hang up.
