California taxpayers are footing a staggering $9.5 billion bill for extending Medi-Cal coverage to undocumented immigrants, a policy expansion that forced the state to borrow $3.4 billion after the program became insolvent and triggered a freeze on new enrollments.
Story Snapshot
- Governor Newsom’s 2024 expansion of Medi-Cal to all undocumented adults drove costs $3.1 billion above estimates, forcing California to borrow billions and freeze enrollment
- Emergency ambulance transport costs for the program soared 382 percent in just two years, jumping from $339 to $1,168 per use
- California remains the only state in the nation providing full-scope Medicaid coverage to undocumented adults using state funds
- New enrollments for undocumented adults will freeze beginning in 2026, with monthly premiums of $30 imposed starting in 2027
Unprecedented Coverage Expansion Triggers Budget Crisis
Governor Gavin Newsom’s administration expanded Medi-Cal coverage to all income-eligible undocumented adults ages 26 to 49 in 2024, making California the first and only state to offer such comprehensive coverage. The expansion initially carried price estimates ranging from $3.1 billion to $6.4 billion annually. By March 2025, actual costs reached $9.5 billion per year from the state’s general fund, creating a $3.1 billion overrun that contributed directly to Medi-Cal’s insolvency. The program now covers approximately 15 million Californians, representing one-third of the state’s population, at a time when California faces a $12 billion budget deficit.

Emergency Services Costs Spike Under Immigrant Coverage
Emergency medical transport costs tied to the Medi-Cal program experienced dramatic increases following the expansion. Ambulance transport costs rose from $339 per use in 2022 to $1,168 in 2024, with state agencies requesting approval for rates as high as $1,637 by 2026. This represents a 382 percent increase over four years. The Department of Homeland Security under the Trump administration publicly criticized Newsom’s policies, directly linking the ambulance cost spikes to emergency Medicaid usage by undocumented immigrants. These emergency services, which federal law requires states to provide regardless of immigration status, became a primary driver of the program’s financial strain.
State Forced to Borrow Billions and Freeze Enrollment
California officials declared Medi-Cal insolvent and borrowed $3.4 billion in early 2025 to cover the shortfall. Republican Representative Kevin Kiley argued that without the $8.5 billion annual spending on coverage for undocumented immigrants, the state would not have needed to borrow anything. The Department of Health Care Services reported that costs accelerated beyond projections due to higher-than-expected enrollment rates and utilization, particularly among seniors whose care averages $15,000 per year compared to the program’s $8,000 average. State finance officials acknowledged the overruns but attributed them to multiple factors including an aging population, not exclusively immigrant coverage.
Budget Deal Implements Enrollment Freeze and Monthly Premiums
On June 30, 2025, California’s Democrat-controlled legislature passed a $330 billion budget deal that freezes new enrollments for undocumented adults beginning in 2026. The agreement also imposes monthly premiums of $30 on undocumented immigrant enrollees starting in July 2027, a significant reduction from Newsom’s original proposal of $100 per month. The California Immigrant Policy Center opposed these measures, arguing they would harm immigrant families and reduce healthcare access. The budget compromise reflects the political tension between progressive immigration policies and fiscal reality, as lawmakers attempt to balance ideology with the state’s deteriorating financial position.
The California experiment stands alone nationally, as federal law prohibits full Medicaid coverage for undocumented immigrants but allows states to use their own funds for such programs. No other state has chosen to implement similar comprehensive coverage. Critics argue this policy represents precisely the kind of fiscal mismanagement that drains resources from legal residents and taxpayers while rewarding those who entered the country illegally. The freeze and premium requirements signal a reluctant acknowledgment that unlimited benefits are financially unsustainable, but the damage to California’s budget has already been done, leaving taxpayers to cover billions in overruns for years to come.
