Two Georgia health care clinic operators are wanted on 24 federal charges of health care fraud after law enforcement officials said the pair bilked Medicaid and Medicare of millions in false claims.

Miguel Angel Hernandez and Maria del Pilar Moreira also face an additional charge of conspiracy to commit health care fraud, U.S. Attorney Sally Yates’ office said Wednesday. The defendants’ whereabouts are unknown.

According to Yates, Hernandez and Moreira owned and operated two clinics: East Point Medical Center and Family First Medical Center in Chamblee. The pair allegedly submitted false claims to Medicare and Medicaid for services that were never provided.

The case was investigated by the U.S. Department of Health and Human Services and investigators from the Georgia Attorney General’s Medicaid Fraud Control Unit and the state Department of Community Health.
