2026 Events (3)
Trump administration deferred over $1 billion in Medicaid payments to California and Minnesota, citing fraud
On July 21, 2026, the Centers for Medicare and Medicaid Services announced it was deferring $867.5 million in Medicaid payments to California and $199 million to Minnesota pending a fraud review, with HHS Secretary Robert F. Kennedy Jr. and CMS Administrator Mehmet Oz citing suspicions of Medicaid fraud but providing no documented evidentiary basis for the specific withholdings. Both states are Democratic-led, and the action follows a pattern of the administration using federal funding as leverage against states with administrations politically opposed to the president.
CMS published Medicaid work-requirement rule with surprise medical-frailty certification mandate, blindsiding states
On June 3, 2026, the Centers for Medicare and Medicaid Services published an interim final rule in the Federal Register implementing the Medicaid community engagement requirement under the One Big Beautiful Bill Act, including a medical-frailty certification provision — requiring healthcare-worker certification rather than self-attestation for individuals with serious health conditions — that state officials said had never been raised in prior federal-state consultations. A Center on Budget and Policy Priorities official reported that CMS staff attributed the provision to the White House. On June 29, officials from 25 states and Washington, D.C. sued HHS Secretary Robert F. Kennedy Jr. and CMS Administrator Mehmet Oz, alleging the medical-frailty provision exceeds the statute's authorization.
Vance and Oz blamed immigrants for California Medicaid fraud that HHS's own watchdog later traced mainly to corporations
At a White House anti-fraud press conference on May 13, 2026, Vice President JD Vance said "tens of billions, hundreds of billions" of dollars in fraudulent Medicaid and Medicare payments in California were going to "illegal aliens" and fraudulent businesses, while CMS Administrator Mehmet Oz said roughly $200 million in "questionable expenditures" was linked to "immigration-related costs" tied to "folks who are undocumented." An HHS Office of Inspector General semiannual report to Congress, covering the six months through March 2026 and released that July, found corporations — through schemes such as unnecessary medical-device billing and Affordable Care Act enrollment fraud — responsible for the healthcare fraud cases it highlighted, without mentioning immigrants.
