If a state is not expanding Medicaid in 2014, does it still use MAGI rules?

Yes. A state's decision whether or not to extend Medicaid coverage for low-income adults in 2014 is not related to the use of MAGI. MAGI rules simplify the eligibility rules and promote coordination between Medicaid and CHIP and coverage available through the Marketplace; coordination will be important for consumers in all states regardless of a state's decision on Medicaid eligibility for low-income adults.
