Have you ever felt like you couldn't trust someone? It's one of the worst feelings in the world, and seniors, in particular, are often the targets of fraud and deception. Billions of dollars and countless hours are wasted every year due to criminal exploitation of Medicare. Sometimes fraud occurs because an unsavory doctor misuses the Medicare numbers he or she can access; other times, criminals steal Medicare numbers from unwitting seniors. The Affordable Care Act contains a $350 million investment to fight fraud as well as provisions that will attack those who defraud the system. Seniors, you can do your part to ensure you're not a victim: Check your Medicare statement to make certain that you received the services listed, and never give your Medicare number to someone who calls on the phone or comes by your home.
