Medicaid is a public health insurance initiative managed at the state level and funded through a partnership between federal and state governments. Its coverage extends to low-income families and individuals, seniors, children and people with disabilities, making it a key component of the U.S. health care landscape.

Given that Medicaid funds are drawn from taxpayers, shifts in local billing volumes help illustrate how public health funding is allocated within a community.

The “Pathology and Laboratory Procedures” classification includes a collection of Medicaid-reimbursed services based on the type of care given, defined by standardized HCPCS and CPT code groupings. Each billing code is assigned to a specific service category for this data set, using consistent code prefixes and numeric intervals to group services accurately and avoid overlap for longitudinal analyses.

The Pathology and Laboratory Procedures category stood at fifth place among all statewide Medicaid payment categories in California in 2024.

According to the Centers for Medicare & Medicaid Services, combined federal and state Medicaid spending stood at about $871.7 billion in fiscal year 2023. This made up roughly 18% of total national health care spending, a sharp jump from around $613.5 billion in 2019, before the COVID-19 pandemic.

This change represents a jump of roughly 40% in several years, mainly driven by higher enrollment and service use in and after the pandemic period.

Recent federal budget acts passed under the Trump administration proposed marked reductions in federal Medicaid funding and changes to program structure. For instance, the “One Big Beautiful Bill Act,” signed into law in 2025, is anticipated to slash federal Medicaid spending by over $1 trillion over 10 years, adding work requirements and increased cost-sharing that may decrease coverage and funding for certain beneficiaries. These moves are likely to push additional costs onto states and limit growth in federal Medicaid support, even as the program serves millions nationwide.
