 We ask seniors how to prevent Medicare scams. If you get a phone call, do not talk to the person. Never give out your Medicare number. They're going to get your number to put in a false claim. Just hang up. How do you detect Medicare fraud? Just like I check my credit card statements, I check my Medicare statements monthly. If you get your statement and you see something that you know you did not have done, you report it. Call the Senior Medicare Patrol.
