What is the difference between the Monthly Medicaid Status Report and the Medicaid flag on MMR?

The Monthly Membership Report (MMR) contains payment information for the reported month; the Medicaid data fields on the MMR represent the beneficiary's Medicaid status used to determine dual status for that month. The Monthly Medicaid Status Report provides information on dual status that may be more current than the anchor months in the MMR that are used for payment. The Monthly Medicaid Status Report gives plans a more complete picture of a beneficiary’s Medicaid status, which can assist with predicting revenue.
