Scammers have been targeting Medicare recipients with a scheme to get “free or low-cost” back and knee braces. They’re calling, running television ads, and mailing letters to get people to give their Medicare information. But if you give them your information, they’ll use it to fraudulently bill Medicare for braces or other medical equipment. This uses up your medical benefits, which means you might not be able to get the right brace later, if your doctor prescribes one.
