The Justice Department is on track to post a record number of health care fraud prosecutions in 2011. Researchers say DOJ reported 1,235 new cases this year, the largest since they began tracking the crime 20 years ago. U.S. Attorney's Offices in Miami, Puerto Rico and Houston accounted for the biggest number of cases. And DOJ officials say recoveries in these cases are bringing lots of money back to the U.S. Treasury. But some onlookers say the federal government can do more to nip health care fraud in the bud by cutting off payments to fraudulent recipients before they happen.
