Do any states provide Medicaid or CHIP-like coverage to undocumented immigrants in 2023 and which states are they?
Executive Summary
Several credible reports from late 2023 through 2025 agree that a growing group of states created state-funded Medicaid or CHIP-like programs for undocumented immigrants by 2023, but they differ on the exact list and scope; most consistently named states include California, Oregon, New York, Washington, Massachusetts, Minnesota, Colorado, New Jersey, Connecticut, Rhode Island, Maine, Vermont, Illinois and the District of Columbia [1] [2]. The programs vary widely — some cover adults, some only children or pregnant people, some are full-scope Medicaid equivalents funded with state dollars, and several carry enrollment caps or sunset dates [3] [4].
1. Who’s being counted as “providing coverage” and why that matters
Reports use different definitions when they say a state “provides Medicaid-like coverage” to undocumented immigrants, which produces divergent state lists. Some sources count full-scope, state-funded Medicaid equivalents for undocumented adults, while others include narrower programs that cover only children, pregnant people, or prenatal care irrespective of immigration status [5] [1]. For example, California’s full expansion to undocumented adults is treated as the clearest case of state-funded Medicaid-equivalent coverage and is highlighted in multiple accounts, while several other states are included because they fund coverage only for children or pregnancy-related services rather than broad adult Medicaid-like benefits [4] [6]. That definitional variation explains why a 2023 snapshot can list “11 states plus D.C.” in one analysis and “14 states” or “six states for adults” in others [1] [2] [3].
2. Which states consistently appear across sources and what they offer
Across the assembled sources, California, New York, Oregon, Washington, Massachusetts, Minnesota, Colorado, New Jersey, Connecticut, Rhode Island, Maine, Vermont, Illinois and D.C. recur as jurisdictions that had enacted some form of state-funded coverage for immigrants regardless of authorization by late 2023 [1] [2]. California is the most prominent example: multiple reports document a large-scale Medi-Cal expansion—projected to cover hundreds of thousands and to become fully effective by January 2024—making it a prototype for full-scope, state-funded coverage [4] [1]. Oregon and Colorado are cited as other early adopters that removed age or categorical limits in 2023, while Minnesota and Illinois are highlighted for phased or limited adult programs that include enrollment caps or scheduled changes [4] [3].
3. How programs differ: adults, children, prenatal care, caps and sunsets
The substantive program differences are important. Several states provide full-scope adult coverage (for example California and some interpretations of Oregon’s 2023 changes), while others limit public funding to children or pregnancy-related services — a common policy choice because federal rules permit state-only coverage in these narrower categories [5] [6]. Some expansions include enrollment caps, fiscal limits, or sunset provisions, notably Utah’s capped children’s program and Illinois’ phased reductions for certain adult age groups slated for termination or change by mid-2025 in some accounts [1] [3]. These structural features mean headline counts of “states providing coverage” can overstate how many people receive stable, comprehensive care long-term.
4. Conflicting tallies and why dates and framing produce different lists
Discrepancies across sources stem from three factors: timing (late-2023 actions vs. 2024–25 implementations), program scope (adult vs. child vs. prenatal), and data cutoffs used by each report. A December 2023 analysis emphasizes an “11 states plus D.C.” figure for taxpayer-funded coverage to over one million immigrants, while later syntheses (cited in 2025 materials) segment the landscape into six states offering adult Medicaid-like programs and a larger set providing child or pregnancy coverage [1] [3] [2]. Some 2025 summaries list 14 states for broader coverage, reflecting additional legislative or administrative changes, but those lists often mix adult and child programs without uniform criteria [2]. Users should treat any single list as a snapshot anchored to a particular definition and date.
5. What the policy debate and data omissions reveal about agendas and uncertainty
Coverage expansions for undocumented immigrants attract clear partisan attention and policy risk, which shapes reporting and advocacy framing. Pro-expansion accounts highlight access gains and coverage numbers (e.g., California’s projected hundreds of thousands newly covered), while critical coverage emphasizes cost controls, enrollment caps, and fiscal exposure or potential federal policy changes that could affect state budgets [4] [1]. Several sources also note important omissions: statewide enrollment data are still evolving, some programs were only operationalized after passage, and several reported expansions included caps or phase-outs not always foregrounded in summaries [3] [1]. For anyone using these tallies, the most reliable approach is to check each state program’s statutory scope and effective date rather than rely on a single aggregated count.
