The FBI in New Jersey is launching a campaign urging the public to report health care fraud — and if it helps generate tips, plans are to expand it nationwide.

The agency office in Newark says tips on crooked doctors and other health care professionals have dropped recently, from 25 in 2008 to just 18 last year.

And referrals from other government agencies are down even more, from 66 in 2008 to 9 last year.

“To make a good case, any case, you need human source reporting,” Newark FBI Special Agent in Charge Michael Ward said in a statement.

Health care fraud is a booming business.

Nationwide, it amounts to anywhere from an estimated $160 million to half a billion dollars a day.
