Undocumented immigrants cannot buy a plan on the ACA Marketplace, but health insurance for undocumented immigrants is available through other channels: employer group plans, private policies purchased directly from a carrier, federally qualified health centers with sliding fees, Emergency Medicaid, hospital emergency care required by federal law, and a growing set of state-funded programs. Each option has its own rules and costs, and knowing which doors are open saves you from wasting time on the ones that are shut.
What the Federal Marketplace Will Not Do
The Affordable Care Act requires every Marketplace applicant to verify U.S. citizenship or lawful immigration status. The federal exchange checks that information against Social Security Administration and Department of Homeland Security records, and anyone who cannot confirm lawful presence is denied enrollment.1Office of the Law Revision Counsel. 42 USC 18081 – Procedures for Determining Eligibility for Exchange Participation, Premium Tax Credits and Reduced Cost-Sharing, and Individual Responsibility Exemptions This is true even if you are willing to pay the full premium with no subsidy. State-run exchanges follow the same verification rules. Undocumented immigrants also cannot receive premium tax credits or cost-sharing reductions.
One boundary worth noting: DACA recipients briefly gained Marketplace access under a 2024 regulation, but as of August 2025 they are no longer eligible for Marketplace coverage, premium tax credits, cost-sharing reductions, or Basic Health Program enrollment. Those already enrolled in most states lost coverage effective September 30, 2025.2HealthCare.gov. Health Coverage for Lawfully Present Immigrants DACA recipients now face the same coverage landscape described below.
Coverage Through an Employer
If you work for a company that offers group health insurance, this is usually the most straightforward path. Under the ACA, employers with 50 or more full-time employees face financial penalties if they fail to offer coverage to their workforce.3Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer Enrollment in the health plan itself does not include a separate immigration status check. The insurer processes your enrollment based on your employment relationship.
Health plans do request Social Security numbers for IRS reporting, and federal regulations require plans to ask up to three times if the number is missing. If you do not have an SSN and are not subject to the individual mandate’s reporting requirements, the absence of a number does not automatically disqualify you.4UCnet. Frequently Asked Questions Why UC Is Asking for Social Security Numbers Practice varies by employer and insurer, so ask the benefits administrator what documentation they actually require before assuming you cannot enroll.
Keeping Coverage After a Job Ends
If you lose a job where you had group insurance, federal COBRA rules let you continue that same coverage for up to 18 months by paying the full premium yourself. You qualify if you were a covered employee, spouse, or dependent under the group plan on the day before the qualifying event, such as job loss or a reduction in hours.5U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers COBRA eligibility depends on prior enrollment, not immigration status. The catch is cost: you pay the whole premium, including the share the employer used to cover, plus a 2% administrative fee. For many people that is out of reach, but it can bridge a gap.
Buying Private Insurance Directly
Nothing in federal law prevents an undocumented immigrant from buying health insurance directly from a private carrier outside the Marketplace. The practical challenge is that many major insurers route individual applicants through the Marketplace or require a Social Security number. Some carriers accept an Individual Taxpayer Identification Number instead, and a smaller set of insurers and health-sharing plans ask for minimal documentation.
Read what a private plan actually covers before you sign. Plans sold outside the Marketplace are not always required to follow ACA rules on essential health benefits, so you may see annual or lifetime caps, pre-existing condition exclusions, or narrow provider networks. Get quotes from more than one carrier, review the exclusions section carefully, and consider an independent broker who has worked with clients without an SSN. Premiums will be higher than a subsidized Marketplace plan, but a private plan still costs far less than paying cash for a hospital stay.
Getting an ITIN
An Individual Taxpayer Identification Number is a nine-digit number the IRS issues to people who need to file federal taxes but are not eligible for a Social Security number. You apply regardless of immigration status by submitting IRS Form W-7 with your tax return.6Internal Revenue Service. Individual Taxpayer Identification Number (ITIN) You will need a valid passport or two supporting documents proving your identity and foreign status, such as a national ID card, foreign driver’s license, or a U.S. State Department-issued visa.7Internal Revenue Service. ITIN Supporting Documents
An ITIN matters for coverage because some private insurers, employers, and state programs accept it in place of an SSN. Filing tax returns also creates income documentation that state programs and sliding-fee clinics may ask for. Apply on or before your tax return due date, and include the return in the same package.
Federally Qualified Health Centers
Federally Qualified Health Centers are the backbone of primary care for uninsured people. They are required by federal law to serve every patient who walks in, regardless of ability to pay or immigration status. They receive direct federal funding through the Health Resources and Services Administration and operate in urban and rural communities across the country.
Every FQHC must run a sliding fee discount schedule based on household income relative to the Federal Poverty Guidelines. Patients at or below 100% of the Federal Poverty Guidelines qualify for a full discount, meaning the center may collect only a small nominal charge. Between 100% and 200%, you pay on a sliding scale with at least three discount levels, so the less you earn the less you pay. Above 200%, you pay the standard fee, which is still typically lower than a private practice or hospital outpatient visit.8Health Resources and Services Administration. Chapter 9 – Sliding Fee Discount Program
FQHCs offer primary care, preventive services, dental care, behavioral health, and pharmacy services, though the mix varies by location. No one asks about immigration status during intake. You will need proof of income (pay stubs, a tax return, or a signed self-declaration) so the center can place you on the correct fee tier. Use the HRSA health center finder to locate one near you.
Emergency Care and Emergency Medicaid
Every hospital that participates in Medicare and operates an emergency department must screen and stabilize anyone who arrives with an emergency medical condition, regardless of insurance, immigration status, or ability to pay. That requirement comes from the Emergency Medical Treatment and Labor Act. Hospitals cannot delay screening to ask about payment, and they cannot turn you away for lack of documentation.9Office of the Law Revision Counsel. 42 US Code 1395dd – Examination and Treatment for Emergency Medical Conditions and Women in Labor
EMTALA covers genuine emergencies: acute symptoms severe enough that lack of immediate treatment could place your health in serious jeopardy, seriously impair bodily functions, or cause organ dysfunction. It also covers active labor when there is not time to safely transfer to another hospital. It does not cover ongoing care, follow-up, or routine services. Once the emergency is stabilized, the hospital’s obligation under the law ends. And EMTALA does not erase the bill. If you cannot pay, contact the hospital’s financial assistance department before the bill goes to collections. Most hospitals have charity care programs or will negotiate reduced charges and payment plans when you can show hardship.
Emergency Medicaid is a separate program that reimburses hospitals for emergency care given to people who meet Medicaid’s income requirements but cannot prove qualifying immigration status. Federal law requires states to provide this reimbursement when the care was necessary for an emergency medical condition, the patient would otherwise qualify for Medicaid on income, and the services are unrelated to organ transplants.10Office of the Law Revision Counsel. 42 US Code 1396b – Payment to States The definition of emergency medical condition tracks EMTALA and explicitly includes emergency labor and delivery, so a low-income undocumented woman delivering at a hospital can have that delivery covered. Coverage does not extend to prenatal care, postpartum visits, or other non-emergency services unless a state has expanded coverage with its own funds.
You do not apply for Emergency Medicaid in advance. The hospital typically initiates the process after providing treatment, and the state Medicaid agency determines eligibility retroactively. If you receive emergency care and think you meet the income threshold, ask the hospital’s financial counselor whether an Emergency Medicaid application has been submitted for you.
State-Funded Programs
A growing number of states use their own funds to cover residents who are ineligible for federal Medicaid or CHIP because of immigration status. Roughly 15 states and the District of Columbia cover children regardless of documentation, and about eight states extend some form of coverage to undocumented adults. Benefits vary widely: some programs are comparable to Medicaid, others are limited to specific age groups, capped enrollment, or particular services like prenatal care.
Eligibility generally requires state residency, an income below a set threshold (often a percentage of the Federal Poverty Level), and basic identification such as a foreign passport, consular ID, or utility bills showing residence. These programs do not report applicant information to federal immigration authorities. State budgets and politics change, so check with your state’s health or human services agency for current rules rather than relying on secondhand information. A local community health organization or legal aid group can help you apply.
Free Clinics and Community Health Programs
Beyond FQHCs, thousands of free clinics, charitable organizations, and community health programs serve uninsured people with no questions about immigration status. Services commonly include immunizations, chronic disease management for conditions like diabetes and hypertension, mental health counseling, and health screenings. Many employ bilingual staff and are built to serve immigrant communities, which makes them easier to approach than a hospital billing office. They can also connect you with other resources: help applying for state programs, referrals to specialists willing to see uninsured patients, and prescription assistance programs that reduce medication costs.
To find these programs, dial 2-1-1, the nationwide helpline that connects callers with community services, or ask at the nearest FQHC. Religious organizations and immigrant advocacy groups in your area often keep updated lists of free and low-cost health resources.
Public Charge and the Fear of Using Coverage
Fear of immigration consequences keeps many undocumented and mixed-status families from seeking care they are entitled to. The public charge ground of inadmissibility allows immigration officers to deny a visa or green card to someone they believe is likely to become primarily dependent on government assistance. The rules are narrower than most people assume.
Under the regulations in effect since 2022, the only benefits considered in a public charge determination are cash assistance for income maintenance and long-term institutionalization at government expense. Medicaid (other than for long-term institutional care), CHIP, ACA health insurance, immunizations and communicable disease testing or treatment, and emergency medical services are all explicitly excluded from consideration.11U.S. Citizenship and Immigration Services. Public Charge Resources
In November 2025 the Department of Homeland Security published a proposed rule that would rescind the 2022 regulations and could allow immigration officers to consider receipt of any means-tested public benefit, potentially including Medicaid and CHIP.12Federal Register. Public Charge Ground of Inadmissibility As of early 2026, the proposed rule has not been finalized and the 2022 regulations remain in effect. If you or a family member is pursuing a green card or visa, talk with an immigration attorney before turning down health benefits out of fear.
One thing that has never counted as a public charge factor: using emergency room services. EMTALA-mandated emergency care and Emergency Medicaid are not considered in any version of the rule, past or proposed. Avoiding the emergency room out of immigration fear can cost you your life, and it will not help your case.
