Medicaid, a public health insurance program managed by states and funded jointly by federal and state governments, insures low-income individuals and families, seniors, children, and people with disabilities. It remains a major component of the national health care system.
Because taxpayer dollars support Medicaid, local billing shifts reflect how communities allocate health care funds.
The “National Codes Established for State Medicaid Agencies” category includes an array of Medicaid services defined by service type, structured according to consistent HCPCS and CPT code classifications.

This represented about 18% of total national health expenditures, a significant rise from approximately $613.5 billion in 2019 before the COVID-19 pandemic.

Federal budget provisions under the Trump administration have addressed sizable reductions to federal Medicaid funding and program restructuring. The “One Big Beautiful Bill Act,” enacted in 2025, is projected to decrease federal Medicaid spending by more than $1 trillion over 10 years, and introduces measures such as work requirements and additional cost-sharing that could limit coverage for certain beneficiaries. These measures are expected to transfer more responsibility to states and constrain federal Medicaid funding growth as the program remains essential to tens of millions nationwide.
