1. (1) The federal Health Care Financing Administration has established policy that federal matching funds will be provided for certain multiple source drugs, at the appropriate match rate, of an amount not to exceed specified upper limits of reimbursement. The specific upper limits of reimbursement are communicated to state Medicaid agencies periodically, with effective dates designated.
2. (2) As specified in 13 CSR 70-20.070, reimbursement for multiple source drugs shall be made in an amount not to exceed the federal 13 CSR 70-20

The Medicaid Pharmacy Manual and updating bulletins shall provide the detailed listing of the specific drug products that shall not be reimbursed in an amount that exceeds the federal upper limit.
