Federal authorities charged 107 doctors, nurses and social workers in seven cities with Medicare fraud Wednesday in a nationwide crackdown on unrelated scams that allegedly billed the taxpayer-funded program of $452 million — the highest dollar amount in a single Medicare bust in U.S. history.

It was the latest in a string of major arrests in the past two years as authorities have targeted fraud that's believed to cost the government between $60 billion and $90 billion each year. Stopping Medicare's budget from hemorrhaging that money will be key to paying for President Barack Obama's health care overhaul.
