At least $41,635 in Medicaid payments were made for services in Chantilly billed under HCPCS codes specifically linked to COVID-19 in 2024, data from the U.S. Department of Health and Human Services Medicaid Provider Spending database shows.
Medicaid is a public health insurance program overseen by the states and funded through state and federal sources. The program serves low-income individuals and families, seniors, children and those with disabilities, making it a core component of the U.S. health care system.
Because these payments come from taxpayers, shifts in local Medicaid billing illustrate how public health funding is distributed in a specific area.
For this report, COVID-19–related claims were determined by identifying HCPCS codes marked as “COVID-19” or “coronavirus”-related within billing or reference descriptions. Therefore, the total is limited to claims labeled directly as COVID-19–related and does not include services for pandemic-related care billed under other medical codes.
By comparison, Richmond had the highest total in Virginia for Medicaid payments linked to COVID-19 services in 2024, with $775,923 in such claims.
In Chantilly, three providers filed Medicaid claims for COVID-19–related services in 2024. The most heavily billed code was Immunoassay, representing $41,267 in payments.
To put this in perspective, Chantilly’s average Medicaid payment per provider for COVID-19–related services stood at $13,878, compared with the state average of $28,521.
In the pandemic years, services related directly to COVID-19 led to a notable share of growth in Medicaid spending in Chantilly.
Total Medicaid payments across all other service categories grew by $14,195,318 from 2020 to 2024, a 52.3% rise.
For the two years before the pandemic, the average annual Medicaid payments in Chantilly were $28,412,423.
According to the Centers for Medicare & Medicaid Services, combined state and federal Medicaid outlays totaled about $871.7 billion in fiscal year 2023, or around 18% of national health spending—a sharp increase from $613.5 billion in 2019, prior to the COVID-19 pandemic.
This growth amounts to nearly 40% in just several years, driven primarily by expanded enrollment and increased Medicaid use during and following the pandemic period.
Congressional budget legislation enacted under the Trump administration has included measures to reduce federal Medicaid funding and change the program’s structure. The “One Big Beautiful Bill Act,” enacted in 2025, is expected to trim federal Medicaid spending by over $1 trillion in the next 10 years and brings policies such as work requirements and higher cost-sharing, potentially limiting funding and coverage for some recipients. These adjustments are likely to shift greater expenses to state governments and curb the pace of federal support, even as Medicaid continues to assist tens of millions of Americans.
