PROVIDENCE — The McKee administration has now raised its own questions about how much the state can legitimately bill Medicaid for patients at the state-run Eleanor Slater Hospital. The state has not officially suspended billing for federal Medicaid reimbursement, but McKee spokesman Matt Sheaff on Wednesday reported this latest wrinkle in the on-going saga: "As ESH processed Medicaid billing for the months of April, May and June 2020, staff raised questions regarding the eligibility of certain expenses." "To ensure the accuracy of bills submitted for Medicaid reimbursement,'' Sheaff said, the Executive Office of Health & Human Services "will retain an outside, independent'' clinical review of patient medical records.
