Senator urges review of Medicare payment errors

Sen. Chuck Grassley of Iowa has demanded a "full accounting" of how Medicare underestimated the extent of fraud, abuse, and waste in a 2006 audit of the medical equipment industry. Grassley, the ranking Republican on the Senate Finance Committee overseeing Medicare, said that a new inspector general's report spotlighting flaws in Medicare's audit raises disturbing doubts about the health insurance program's efforts to identify and reduce waste.
