Medicaid is a joint federal-state program that provides public health insurance for low-income groups, families, children, seniors, and people with disabilities, and it remains one of the largest components of the U.S. health care system. More about program funding can be found at this resource.
Since Medicaid is financed by taxpayers, shifts in local claims volumes help illustrate how public health care funding is distributed in each community.

According to the Centers for Medicare & Medicaid Services, combined state and federal Medicaid expenditures reached approximately $871.7 billion in fiscal year 2023, making up around 18% of all national health spending, up from around $613.5 billion in 2019, before the onset of the COVID-19 pandemic.
This represents about 40% growth in Medicaid costs in a few years, largely due to broader enrollment and increased utilization during and after the pandemic.
Major federal budget enacted under the Trump administration introduced substantial changes in Medicaid funding and structure. The “One Big Beautiful Bill Act,” enacted in 2025, is forecast to reduce federal Medicaid spending by more than $1 trillion over 10 years, incorporating requirements like work mandates and higher cost-sharing. These policies could reduce coverage for some, raise costs to states, and limit future federal Medicaid growth, while the program continues to serve tens of millions nationwide.
