FILE - In this Oct. 13, 2009, file photo the Senate Finance Committee's ranking Republican Sen. Charles Grassley, R-Iowa, wears two pairs of glasses while reading during the committee's hearing regarding health care reform on Capitol Hill in Washington. Medicare overpayments, which can be anything from a billing error to a flagrant scam, totaled more than $36 billion in 2009, according to the Obama administration. Grassley's office, which is investigating the contracting program, obtained Medicare data for the last four years on how long it took to refer cases to federal agents.
