According to a recent report from the Washington Post, medical suppliers have billed Medicare up to $92 million dollars for wheelchairs and various other pieces of home medical equipment.  Unfortunately for the American taxpayer, those claims were filed using the names and identification numbers of deceased physicians.

Senate investigators estimate that between 384,730 and 572,238 fraudulent claims have been honored by The Centers for Medicare and Medicaid Services (CMS) since 2000. 

It's no wonder that since 1990 Medicare has been a familiar sight on the GAO's "high risk" list.
