If the Marketplace is a government entity, States will have the option to enable their State-based Exchange to make Medicaid eligibility determinations for non-MAGI eligibility groups. Depending on the arrangements made in each State, such an Exchange can make all Medicaid eligibility determinations, only eligibility determinations based on MAGI, or assessments of eligibility based on MAGI. The FFE will not be making Medicaid eligibility determinations for non-MAGI groups; the FFE will either do final determinations or assessments for the MAGI eligibility groups.
