LITTLE ROCK, Ark. — An Arkansas doctor and a medical sales representative have been accused of taking part in a scheme which defrauded the U.S. military’s health insurer of more than $12 million.

Federal prosecutors announced Friday that Dr. Joe David May and Derek Clifton have been charged in a 43-count indictment. Both men are from Alexander.

According to prosecutors, Tricare, the military insurer, paid over $12 million in 2015 for prescriptions, which were rubber stamped without examining patients.

The indictment says the two men also took part in a widespread effort to obstruct an investigation by authorities.

Businessman indicted in $510 million Tricare fraud scheme Federal prosecutors say a Mississippi businessman has been indicted in one of the nation’s largest health care fraud investigations.

The charges in the indictment include conspiracy, wire fraud, mail fraud, anti-kickback violations, aggravated identity theft, money laundering, lying to the FBI, falsifying records and obstruction of justice.

According to the indictment, Tricare beneficiaries allegedly were recruited, sometimes for pay, to receive expensive compounded drugs they didn't need. Prescriptions went to a Mississippi pharmacy, which shipped drugs nationwide and billed Tricare for reimbursement.

Authorities allege Clifton, a former basketball coach in Baxter County, sent May pre-filled prescriptions and May rubber stamped them for over 100 beneficiaries, for which Tricare paid $4.5 million.
