Medicaid Funding Under Scrutiny: A New Era of Federal Oversight
The Centers for Medicare and Medicaid Services (CMS) is signaling a significant shift in how it addresses potential fraud within the Medicaid program. Historically, CMS partnered with states to identify and resolve issues, denying federal funds only after audits or investigations confirmed wrongdoing. Now, the agency is increasingly relying on tools to pause or withhold federal funding based on suspected fraud – a move impacting Minnesota and potentially other states and raising concerns about budget stability and access to care.
From Disallowances to Deferrals and Withholds: Understanding the Changes
For years, CMS primarily used “disallowances” – denying federal matching funds for expenditures later deemed unallowable. This process, while effective, could take years to resolve, with states bearing the burden of proving expenditures were legitimate. The new approach introduces “deferrals” and “withholds,” offering more immediate, and potentially broader, consequences.
Deferrals pause payment for expenditures while CMS investigates. Withholds, a more drastic measure, halt future payments altogether. In January 2026, CMS announced a temporary deferral of $259 million in federal Medicaid payments to Minnesota, an unusually large amount. Simultaneously, CMS began withholding $515 million in quarterly federal Medicaid payments from Minnesota, pending a hearing.
The Burden of Proof Shifts
A key difference lies in the burden of proof. With disallowances, states could appeal and demonstrate the legitimacy of expenditures. With deferrals and withholds, the onus is on states to proactively prove expenditures are “allowable” – a potentially significant challenge. This shift creates uncertainty for state budgets and could impact Medicaid enrollees and providers not involved in any fraudulent activity.
Beyond Minnesota: A Wider Net
While CMS initially focused on Minnesota, California, Maine, and New York, the House Committee on Energy and Commerce has expanded the scope, requesting information about potential Medicaid fraud from 11 states, including some with Republican governors. This suggests a broader investigation and potential for similar actions in other states.
Impact on State Budgets and Medicaid Services
States operate under balanced budget requirements. The sudden loss of federal funds through withholding could disrupt programs and force difficult decisions, such as reducing provider payments, limiting covered services, or restricting eligibility. The timing is particularly challenging as states grapple with implementing changes from the 2025 reconciliation law, which already reduced federal Medicaid funding and introduced new administrative requirements.
What States Are Saying
The National Association of Medicaid Directors (NAMD) has suggested several actions CMS could take to assist states in addressing fraud, waste, and abuse, including sharing best practices, improving data interoperability, and responding more quickly to fraud reports.
Frequently Asked Questions
What is a disallowance?
A disallowance is when CMS denies federal matching funds for prior state Medicaid expenditures determined to be unallowable.
How does a deferral differ from a withhold?
A deferral pauses payment while CMS investigates, while a withhold halts future payments altogether.
What is the role of the Departmental Appeals Board?
States can appeal disallowance decisions to the Departmental Appeals Board, but the state still has the burden of proof.
Pro Tip: States should proactively review their Medicaid programs and strengthen internal controls to minimize the risk of fraud and ensure compliance with federal regulations.
