Medicaid is a public health insurance program managed by states and jointly financed by the federal and state governments. It provides coverage for low-income groups, including individuals, families, seniors, children, and people with disabilities. This makes it one of the largest components of the U.S. health care system. For more, see the Commonwealth Fund explainer.
Because Medicaid is funded by taxpayers, variations in billing locally reveal how health care dollars are distributed across the community.

According to the Centers for Medicare & Medicaid Services, combined federal and state spending on Medicaid totaled around $871.7 billion in fiscal year 2023. That amount represented approximately 18% of overall U.S. health expenditures, a notable rise from $613.5 billion in 2019, before the onset of the COVID-19 pandemic.
The roughly 40% jump in spending over several years stems largely from greater enrollment and increased service use during and after the pandemic period.
Recent federal budget legislation enacted under the Trump administration brings major changes to Medicaid funding. The “One Big Beautiful Bill Act,” signed into law in 2025, is forecasted to cut more than $1 trillion from federal Medicaid funding over 10 years, and it introduces policies like work requirements and higher cost-sharing. These measures could reduce benefits and funding for some groups, shifting more responsibility to states and slowing the growth rate of federal Medicaid contributions even as millions remain enrolled in the program.
