Under the Patient Protection and Affordable Care Act (ACA; P.L. 111-148, as amended), the definition of income for eligibility for certain Medicaid populations and premium credits in the exchanges is based on modified adjusted gross income (MAGI). The initial intent of using MAGI was to standardize the definition of income for Medicaid eligibility purposes to reduce some of the variability and complexity that exists under the current program and to provide consistency between Medicaid and the health insurance exchange.

The use of MAGI, however, raised some concerns among Congress and the Obama Administration, as the definition in ACA excluded some types of income either partially or altogether. Of particular interest was the potential impact on eligibility for Medicaid and premium credits for early retirees (aged 62 through 64) receiving Social Security benefits, as some or all of their Social Security income may have been excluded from the MAGI definition of income. By excluding some types of income from the ACA definition, individuals and families with a higher percentage of total income relative to the federal poverty level may qualify for Medicaid and premium credits.

To address these concerns, P.L. 112-56 was enacted into law on November 21, 2011, which among other things, amended the definition of income for these programs and included nontaxable Social Security in the definition of MAGI. The new law, however, does not address other forms of non-taxable income that are not currently in the MAGI definition (e.g., retirement plan contributions, gifts and inheritance). In evaluating the definition of MAGI, a number of issues might be considered. First, an alternative definition may add complexity compared with the use of MAGI. Specifically, because adjusted gross income (on which MAGI is based) can be computed largely from information on an individual’s federal tax return, verification of income is streamlined. If an alternative definition is used that is not based on tax return information, the administrative complexity of verifying nontaxable income from different sources comes into play. Second, the definition was developed to ensure coordination between Medicaid and premium credits in the health insurance exchange. A change in the definition of income for Medicaid also would be necessary for premium credits to ensure consistency between Medicaid and the premium credit offered to selected individuals who purchase private health insurance through the exchanges. Finally, the enactment of P.L. 112-56 focused largely on the inclusion of Social Security benefits in income definitions for eligibility purposes. However, most other low-income programs include other types of income (e.g., nontaxable pensions) and asset holdings that are also excluded from MAGI.
