Federal authorities charged a Carmel man on Friday with using his Indianapolis business to defraud the Indiana Medicaid program of more than $1 million.

Donald Hamilton, 49, faces one count of health care fraud, five counts of false statements in a health care matter and two counts of money laundering.

He faces a maximum sentence of 55 years in prison if convicted on all counts and a fine of $250,000 for each charge.

The federal indictment alleges that Hamilton used his company, Hamilton Medical Inc., to generate false invoices showing that compression stockings for another of his companies, Indianapolis-based Compression Etc., cost almost three times what he paid for them.

Hamilton sent invoices to the Indiana Medicaid program for reimbursement for an amount much higher than allowed by law, according to the charges.

The charges were announced by Joseph Hogsett, U.S. Attorney for the Southern District of Indiana. He said the investigation was a collaborative effort among the Department of Health and Human Services, Federal Bureau of Investigation, the Internal Revenue Service’s criminal investigations unit and the Indiana Attorney General’s Medicaid fraud control unit.
