From the DOJ here:
Last July the Department of Justice announced a record-breaking enforcement action against health care fraud. We coordinated the efforts of more than 1,000 state and federal law enforcement agents to charge more than 400 defendants—including 56 doctors—with more than $1.3 billion in fraud.
Today I am announcing that we are breaking records again.
The Department of Justice, in conjunction with the Department of Health and Human Services, is announcing the largest health care fraud takedown operation in American history.
This year we are charging 601 people, including 76 doctors, 23 pharmacists, 19 nurses, and other medical personnel with more than $2 billion in medical fraud.
