Medicaid operates as a public health insurance initiative managed by states and financed jointly by state and federal governments. The program supports low-income people and families, along with seniors, children and those with disabilities, making it a major element of the U.S. health care landscape.

Because Medicaid funding comes from taxpayers, shifts in local billing reveal how community resources are directed toward health care.

The “Pathology and Laboratory Procedures” grouping includes Medicaid-billed services distinguished by type of care and assigned according to standardized HCPCS and CPT codes. In this review, every billing code was categorized using matching code prefixes and ranges to combine similar services, prevent duplicate counting and maintain ranking accuracy over time.

According to the Centers for Medicare & Medicaid Services, combined state and federal Medicaid expenditures reached approximately $871.7 billion in fiscal year 2023. That made up about 18% of the nation’s total health costs, up substantially from roughly $613.5 billion in 2019, before the COVID-19 pandemic.

This increase amounts to nearly 40% growth in only a few years, with much of the change attributed to expanded enrollment and higher health service use during and after the pandemic.

Recent federal legislation enacted during the Trump administration included significant proposals to overhaul Medicaid’s funding structure. The “One Big Beautiful Bill Act,” approved in 2025, is expected to reduce federal Medicaid funding by more than $1 trillion over the next 10 years. The act introduces new requirements, such as work obligations and increased out-of-pocket costs, that could reduce coverage for some beneficiaries. With these changes, states will likely face greater costs even as the program serves millions of Americans.
