Medicaid accounts for one-fifth of U.S. health care spending and covers more than a quarter of Americans. LDI researchers have examined the services it provides in supporting aging adults, people with disabilities, and children, as well as its role in health crises such as chronic disease and suicide. They have also studied its role in the health care sector and its effects on workers and local economies. Below are select key findings from recent peer-reviewed research, along with expert insights for policymakers considering changes to Medicaid funding in the federal budget.

Making Medicare Affordable

Medicaid supplemental insurance covers most cost-sharing for low-income individuals on Medicare. The loss of eligibility for Medicaid supplemental insurance was associated with lower outpatient care use and fewer prescriptions filled among Black and Hispanic beneficiaries.

Imposing Medicaid Work Requirements

Efforts to tie work or community engagement to benefits may reduce participation among those covered by the requirements and among those who are not. While public opinion supports work requirements, it does not support cutting coverage for noncompliance.

G., and Underhill, K. 2019. “Assessment of Medicaid Beneficiaries Included in Community Engagement Requirements in Kentucky.” JAMA Network Open; and, Venkataramani, A. S., Bair, E.

Supporting Safety Net and Rural Hospitals

Medicaid expansion was associated with decreased uncompensated care and increased operating margins at safety net hospitals. Conversely, closures of rural hospitals, many of which rely on Medicaid, are associated with significant reductions in health care sector employment.

Expanding the Long-term Care Workforce

Demand for Medicaid-funded home- and community-based services has grown. However, the workforce to support this demand has lagged. Currently, there is a larger demand for home- and community-based services than there is available workforce, creating a clear opportunity for job expansion.

Caregiving for Older Adults and People with Disabilities

Medicaid provides coverage for services that allow older adults and people with disabilities to live in the community. Losing those services could increase nursing home use or unpaid caregiving, impacting the costs to families and the larger economy.

Preventing Suicide

Medicaid is part of a health infrastructure that can help identify and address risk factors for suicide, especially when it integrates data that is collected in silos, such as involvement with the criminal justice system.

L., Ware, N., Shoyinka, S., & Lim, S. 2023. “Building an Integrated Data Infrastructure to Examine the Spectrum of Suicide Risk Factors in Philadelphia Medicaid.” Administration and Policy in Mental Health and Mental Health Services Research.


Supporting Pregnancy Care

Medicaid plays a substantial role in pre-pregnancy care, and the care it provides between pregnancies can reduce future pregnancy complications.

Addressing the Overdose Crisis

Medicaid innovations, such as mobile and low-barrier treatment of opioid use disorder, are key to reaching and treating people with substance use disorder.

Get Your Foot in the Door: Exploring Patient Perspectives on Low-Barrier Treatment for Opioid Use Disorder.Drug and Alcohol Dependence.


Keeping Kids Covered

Examining coverage changes during and after the COVID-19 pandemic reveals that 12-month and multi-year continuous eligibility policies targeting young children enrolled in Medicaid and CHIP have the potential to improve children’s coverage stability and access to care over time.
