Income Rules
A. The Affordable Care Act (ACA) requires that state Medicaid programs use modified adjusted
gross income or MAGI-based methodology for determining the income of an individual and
the individual’s household. MAGI methodology and rules are required in determining
eligibility for Medicaid or Children’s Health Insurance Program (CHIP) or an 1115
demonstration that involve MAGI covered populations of children, pregnant women and
parents and needy caretaker relatives. The Aged, Blind and Disabled population is exempt
from MAGI rules.
B. The MAGI methodology is aligned with the process used to determine eligibility for the
premium tax credits and cost sharing reductions available to certain individuals purchasing
coverage through the federal health insurance marketplace. The requirement that both
Medicaid and the marketplace use MAGI-based income methodologies is designed to promote
coordination and avoid gaps in coverage, to the extent possible, for individuals that transfer
between different types of insurance affordability programs.
C. The use of liberalized income rules under 1902(r)(2) of the Social Security Act is prohibited
under MAGI based methodology. This provision is only available to certain ABD covered
categories of eligibility.
