YOUNGSTOWN — Two Mahoning County doctors accused of a scheme to defraud Medicare and Medicaid were arraigned Tuesday in U.S. District Court.

Samir Wahib, 53, of Canfield, and Joni Canby, 62, of Poland, pleaded not guilty to their charges, including one related to kickbacks involving a federal healthcare program and multiple counts of conspiracy to commit health fraud.

Wahib faces eight charges, and Canby faces five.

Both were released on a personal recognizance bond, meaning they didn’t have to pay anything.

Magistrate Carmen Henderson ordered that Wahib surrender any passport and travel-related document and not travel outside of the Northern District of Ohio or state of Indiana.

He also is ordered to have no contact with anyone who may be a victim or witness in the investigation or prosecution of his case and have no contact with his co-defendants.

Canby has the same restrictions as Wahib except she can only travel in the Northern District of Ohio.

The docket in the case indicates that Canby is now represented by three attorneys, including Carole S. Rendon, who is a former U.S. attorney for the northern district of Ohio.

Neither doctor has any new hearings scheduled.

Wahib and Canby were indicted earlier this month on charges accusing them of attempting to obtain reimbursement for testing that was not medically necessary.

Michelle Kapon, 41, of Youngstown, also was named in the indictment, but charged separately in a bill of information for conspiring with Wahib and Canby to accept kickbacks from Wahib.

All three are medical doctors, Wahib and Canby are obstetrician-gynecologists; and Kapon is a family medicine practitioner. Wahib has been licensed since 1999, Canby since 1985 and Kapon since 2009, according to the Ohio Medical Board.
