California Freezes Medi-Cal for Undocumented Adults as 2.2 Million Could Lose Coverage by 2030

Summary
California has begun rolling back Medi-Cal by freezing enrollment for undocumented adults, with researchers projecting the uninsured rate will climb from 95% coverage today to nearly 15% by 2030.
UC Berkeley and UCLA researchers estimate 2.2 million people could lose insurance over four years as state budget cuts combine with new federal restrictions, hitting undocumented immigrants, low-income residents, and Southern California hardest.
State actions already include about 86,000 fewer undocumented immigrants covered, while next summer brings dental benefit cuts and new monthly premiums that could push roughly 800,000 people off insurance.
Federal changes tied to Trump’s tax law could strip more than $30 billion a year from Medi-Cal in 2027, while work-reporting rules and shorter eligibility periods are expected to cost another 1.3 million people coverage.
The retrenchment marks a sharp reversal for a state that expanded Medi-Cal to undocumented adults in 2024 after more than 5 million Californians gained coverage under the Affordable Care Act.

Could the strict administrative hurdles meant to save billions actually trigger a catastrophic public health crisis across the state?
California’s 2026 Medi-Cal Freeze: How 1.3 Million Undocumented Adults Lost Coverage and What It Means for Public Health, Budgets, and Families
Overview
California’s 2026 Medi-Cal freeze for undocumented adults was triggered by soaring program costs and a sharp drop in state tax revenues, both worsened by federal tariffs and massive Medicaid cuts under H.R. 1. As a result, the state lost $30 billion in annual federal funding and began sharing Medicaid data with ICE, creating widespread fear and causing over 86,000 undocumented immigrants to lose coverage in just two months. New work and premium requirements are expected to double the uninsured rate among undocumented adults by 2030, while federal policy changes threaten millions more with loss of health coverage nationwide.
