How does MAGI affect eligibility for the Medicaid program?
The Affordable Care Act (ACA) introduces a new, streamlined system for determining Medicaid eligibility for most children and adults under age 65 -- Modified Adjusted Gross Income or "MAGI". MAGI rules will simplify the way Medicaid counts income and determines household size. MAGI will replace the complex Medicaid income rules with income tax filing rules. The new MAGI methodology is also important in terms of what sources of income count in determining eligibility. For example, child support, Temporary Assistance to Needy Families (TANF), Supplemental Security Income (SSI), and worker compensation are not counted as income under MAGI rules. For most Medicaid recipients, Medicaid eligibility will not change under the MAGI rules.
