The funniest form of Medicare fraud is when insurers diagnose patients with illnesses they don't have. The weirdest example is when insurers write down that a patient has HIV or AIDS even when they've never been tested or prescribed drugs for it. So they can bill for more!

So, for example, UnitedHealth has tried to claim that all of these patients that *they* *without ever talking to a doctor or the patient* classified as having HIV are actually HIV patients when confronted. But at the same time, they're not offering those patients treatment. Odd!
