At least $402,366 in Medicaid funds were billed in Vallejo in 2024 for services reported under HCPCS codes specifically linked to COVID-19, data from the U.S. Department of Health and Human Services Medicaid Provider Spending database show. That was a 252% jump over the prior year, when providers submitted $114,322 in claims under the same codes.
Medicaid, a public health insurance program managed by states and funded through federal and state partnerships, serves low-income residents, seniors, children and people with disabilities. It remains one of the largest components of U.S. health care.
Tax revenues support Medicaid payments, so shifts in local billing highlight how communities allocate public health resources.
For this report, COVID-19–specific services were identified using HCPCS codes marked or categorized as “COVID-19” or “coronavirus”-related in billing fields or reference sources. The analysis covers only items directly identified in data as COVID-related and does not include pandemic care billed under other or broader codes.
For reference, San Jose posted the highest amount of Medicaid payments for COVID-19 services in California in 2024, with $5,601,479 in virus-linked claims.
Vallejo had four providers billing Medicaid for COVID-19–related care in 2024, with COVID-19 Vaccine Administration comprising $327,247 of claims.
The average Medicaid payment per provider for COVID-19–related services in Vallejo came to $100,592, topping the state average, which was $52,976.
COVID-19–labeled services made up a major portion of Vallejo’s Medicaid spending increase during the pandemic years.
Medicaid payments across all other claim groups rose by $33,590,327 from 2020 through 2024, a 119.8% gain.
Centers for Medicare & Medicaid Services data indicate combined federal and state Medicaid spending reached about $871.7 billion in the 2023 fiscal year—about 18% of total U.S. health costs—up from roughly $613.5 billion in 2019, ahead of the pandemic.
This surge represents an increase of about 40%, largely attributed to expanded coverage and higher use during and after the pandemic years.
Recent federal budgeting under the Trump administration included plans for substantial reductions in Medicaid funding and program restructuring. For instance, the “One Big Beautiful Bill Act,” signed in 2025, is forecast to reduce federal Medicaid expenditures by more than $1 trillion over the next 10 years and implements policies like work requirements and increased cost-sharing that could cut access and funds for some recipients. These policies are expected to place more financial responsibility on states and limit increases in federal Medicaid aid, even as the program continues to cover tens of millions nationwide.
