LITTLE ROCK — Empower Healthcare Solutions, a managed care organization that serves roughly 20,000 high-need Medicaid beneficiaries in Arkansas, is under investigation by state regulators and the attorney general’s office for allegedly defrauding Medicaid.

In a letter sent to the state’s Office of Medicaid Inspector General last week, Deputy Attorney General Lloyd Warford said a full investigation into allegations of fraud was only now getting under way. But an initial review found “sufficient credible evidence” to support the suspension of Empower from the Medicaid program, he wrote.
