EXPANDED INCOME ELIGIBILITY FOR HEALTH INSURANCE
WHAT IS MEDICAID EXPANSION AND WHY IS IT IMPORTANT?
States can employ several strategies to increase health insurance coverage for their residents, and the most widely studied strategy is the expansion of Medicaid eligibility. Medicaid is a joint federal and state program that provides health insurance to low-income households, covering one in five Americans and 41% of all live births in the United States.1,2
Under the federal Patient Protection and Affordable Care Act, also known as the ACA, states can expand Medicaid eligibility for most adults with incomes at or below 138% of the federal poverty level (FPL). Approximately 2.9 million uninsured adults would become newly eligible for Medicaid if the remaining 10 nonexpansion states expanded the income eligibility for Medicaid to 138% of the FPL.3
WHAT PROGRESS HAVE STATES MADE SINCE THE 2020 ROADMAP TO ADOPT AND IMPLEMENT MEDICAID EXPANSION?
4 States Have Newly Implemented Medicaid Expansion
As of October 2020, 37 states had expanded Medicaid income eligibility for most adults with low incomes through the Affordable Care Act (ACA). Since then, four more states have implemented Medicaid expansion under the ACA.
- Missouri, Oklahoma, and South Dakota bypassed state legislatures and enacted Medicaid expansion through voter referendums.
- In contrast, North Carolina enacted bipartisan legislation to expand Medicaid.
Expanding Income Eligibility for Medicaid Means Millions More Have Access to Health Insurance
The four states that expanded Medicaid since the 2020 Roadmap increased income eligibility for adults without children from 0% to 138% of the Federal Poverty Level (FPL). Income eligibility limits for parents in a family of three also increased to 138% of the FPL after expansion, from 21% of the FPL in Missouri, 37% of the FPL in North Carolina, 41% of the FPL in Oklahoma, and 46% of the FPL in South Dakota, in the year prior to expansion in each state.
In addition to greater access to health insurance in expansion states, some nonexpansion states significantly altered eligibility criteria.
- Provided they meet a work requirement, more childless adults and parents in Georgia are eligible for Medicaid in 2024 than in 2020. Income eligibility for those meeting the work requirement is 100% of the FPL in 2024. In 2020, childless adults were not eligible for Medicaid coverage and only parents whose incomes were up to 35% of the FPL were eligible.
- Tennessee also increased its parent eligibility threshold from 82% of the FPL in 2023 to 105% of the FPL in 2024.
Medicaid Expansion Is Gaining Momentum After Years of Stagnation Among Nonexpansion States
In the year following North Carolina’s successful Medicaid expansion legislation, nonexpansion states with majority Republican legislatures have had notable bipartisan progress towards Medicaid expansion. For example, in 2024:
- Mississippi’s first ever bipartisan Medicaid expansion bill fell just short of the finish line when both chambers of the legislature could not agree on a final proposal.
- Legislation in Alabama to allow gambling revenue to be used for health care coverage for low-income adults (similar to the Medicaid expansion under the ACA) received bipartisan support, although the expanded coverage was eventually removed from the legislation.
- In Kansas, legislators held the first hearing on Medicaid expansion in 4 years.
States Considered Medicaid Work Requirements, Which May Limit Access to Care
Both expansion and nonexpansion states are increasingly considering imposing work reporting requirements as a condition for Medicaid eligibility, although implementation is dependent on the approval of the federal government. Georgia is the only state currently implementing a work reporting requirement for Medicaid. In 2023, Georgia implemented its partial Medicaid expansion program, Pathways to Coverage, which only covers individual up to 100% of the FPL and requires enrollees to work 80 hours each month to maintain their Medicaid coverage.
The impact of work requirements on the effectiveness of Medicaid is not fully clear. However, because of these requirements, far fewer individuals in Georgia than are eligible based on income alone enrolled during the first year of the program. As both expansion (e.g., South Dakota and North Carolina) and nonexpansion (e.g., Kansas and Mississippi) states consider work requirements, more needs to be understood about how this policy impacts those eligible for and enrolled in Medicaid.
1 State Increased the Pregnancy Medicaid Income Eligibility Threshold
Income eligibility during pregnancy is higher than income eligibility for childless adults or for parents who are not pregnant. Since 2020, Oklahoma was the only state to increase its Medicaid income eligibility threshold during pregnancy, from 138% of the FPL in 2022 to 210% of the FPL in 2023.
States Invested Funding to Expand Medicaid Coverage to Additional Populations
Since October 2020, four expansion states have implemented policies to extend coverage beyond the ACA guidelines, including to most adults with low incomes who were previously ineligible due to immigration status (California, the District of Columbia, Oregon, and Washington). In 2025, Colorado will expand coverage to children and pregnant individuals who were previously ineligible due to immigration status.
States Rapidly Adopted Extended Medicaid Postpartum Coverage
Before passage of the American Rescue Plan Act (ARPA) of 2021, Medicaid coverage for pregnant individuals typically only lasted through 60 days postpartum. When eligibility for pregnancy Medicaid coverage ends, then the person must switch to traditional parent Medicaid or use a subsidy to purchase health coverage on the Marketplace. Parent income eligibility for Medicaid is typically lower than eligibility thresholds during pregnancy.
In nonexpansion states, many of these new parents lose health insurance coverage after the postpartum period because their incomes are too high for traditional parent Medicaid eligibility, but not high enough (100% of the FPL) to receive subsidies to purchase insurance on the Marketplace.
Prior to the passage of ARPA, a small number of states sought to extend postpartum Medicaid coverage through Section 1115 demonstration waivers. ARPA expanded the pathways for states to extend pregnancy Medicaid coverage during the postpartum period, by including a temporary state option to use state plan amendments. The option for states to extend coverage via state plan amendments through ARPA went into effect on April 1, 2022, and the 2023 Consolidated Appropriations Act (CAA) made this temporary option permanently available to states.
Since October 2020, 47 states have implemented extended pregnancy Medicaid coverage to 12 months postpartum. As of December 1, 2024, two additional states (Iowa and Idaho) are in the process of extending coverage, leaving just Arkansas and Wisconsin with 60-day postpartum Medicaid coverage.
As states have extended Medicaid coverage through the first year postpartum, states need to identify how systems of care can work together to provide support during this longer coverage period – including identifying which providers are responsible for ongoing support of new parents in the first year postpartum.

Moving Forward: Ongoing Financial Incentives and Continuous Coverage for Children Provide Opportunities for Continued Impact
Looking forward, states have multiple opportunities to improve access to Medicaid coverage, including accessing financial incentives to reduce the cost of the Medicaid expansion under the ACA and policy changes to lengthen coverage periods for children.
The mostly southern, nonexpansion states play an important role for promoting perinatal health in the US – Texas and Florida alone make up 17% of births nationwide, at 11% and 6%, respectively.4 For nonexpansion states, significant federal incentives that began during the COVID-19 pandemic remain in place permanently, which may further offset costs of Medicaid expansion. The American Rescue Plan Act of 2021 provides states that have not yet expanded Medicaid with a 5-percentage point increase in their regular federal matching rate for 2 years after expansion takes effect. Because of high federal contributions to the cost of expanding Medicaid coverage, implementing Medicaid expansion may lead to net savings for states.5
States also continue to look for opportunities to improve insurance coverage among children. The 2023 CAA required all states to provide 12-month continuous coverage for children to provide stability in insurance coverage. Several states have sought approval from the Centers for Medicare and Medicaid Services for more generous, multi-year continuous eligibility for children covered under Medicaid.
As of October 2024, New Mexico, Oregon, and Washington have begun implementing continuous coverage for children birth to age 6. Additionally, California, Colorado, the District of Columbia, Hawaii, Illinois, Minnesota, New York, North Carolina, Ohio, and Pennsylvania are developing policies to provide multi-year eligibility for various lengths of time, and other states introduced unsuccessful legislation to provide multi-year continuous eligibility for children.
As states implement policies to promote extended coverage among children and parents in the postpartum period, more research is needed to understand the impact of these policies on family wellbeing.
