Health Insurance Without an SSN or With an ITIN

By ITINWorks Team · How we verify

Changes to know (October 2026): California closed full Medi-Cal to most new undocumented adults on January 1, 2026; Illinois, Minnesota and D.C. cut adult programs; and from January 1, 2027, Marketplace premium tax credits go only to citizens, green-card holders, Cuban/Haitian entrants and COFA migrants.

Can I Use an ITIN for Health Insurance?

Yes. An ITIN can go on a job-based plan, a private plan bought outside the Marketplace, or a state program application, but it never makes you eligible by itself. Immigration status decides Marketplace and Medicaid eligibility: undocumented immigrants can't use HealthCare.gov, while lawfully present immigrants can, with subsidies limited to 4 groups from January 1, 2027.

You don't need an SSN to protect your family's coverage either. HealthCare.gov says family members who aren't applying won't be asked their immigration status, and a state can't deny an eligible applicant because a relative who isn't applying didn't share it. That means an undocumented parent can apply for a U.S.-citizen child.

What Health Insurance Options Do I Have Without an SSN?

Without an SSN, 4 paths work in every state: community health centers that charge by income, Emergency Medicaid for emergencies, job-based insurance, and private plans bought outside the Marketplace. State-funded programs add coverage for children regardless of status in 14 states and D.C., and lawfully present immigrants can also use the ACA Marketplace.

Here is how the options compare on whether an SSN is required, how you pay, and who qualifies:

1. Community health centers — every state. Federally funded health centers can't deny care because you can't pay, and their discounts depend only on income and family size. They offer primary care, dental, mental health and pharmacy help. Find one at findahealthcenter.hrsa.gov.
2. Emergency Medicaid — every state. Covers emergency room care, emergency surgery, and labor and delivery for people who meet Medicaid income rules but are excluded because of immigration status. It doesn't cover routine or preventive care.
3. State-funded coverage — some states. 14 states and D.C. cover children regardless of immigration status. Adult coverage is much narrower and shrank in 2025–2026; see the state list below.
4. Job-based insurance — through your employer. If your job offers health insurance, you can enroll regardless of immigration status. No law requires an SSN to enroll.
5. Private plans — bought directly from an insurer. Undocumented immigrants can buy a private plan outside HealthCare.gov at full price. Ask the insurer whether its application takes an ITIN.

What Medicaid Coverage Is Available Without an SSN?

Two kinds of Medicaid reach people without an SSN. Emergency Medicaid, in all 50 states, covers ER care, emergency surgery, and labor and delivery for people who meet Medicaid income rules but are excluded by immigration status. State-funded programs cover children regardless of status in 14 states and D.C., but adults only in a few.

Emergency Medicaid (every state)

Federal law requires every state to provide Emergency Medicaid to people who meet the income requirements for regular Medicaid but are excluded because of their immigration status. Emergency Medicaid covers:

• Emergency room visits and hospitalization
• Emergency surgery
• Labor, delivery, and postpartum care
• Emergency dialysis (in some states)

It does not cover routine doctor visits, preventive care, prescriptions, dental, or mental health outside of emergencies. Income limits follow your state's Medicaid rules.

State-funded coverage regardless of immigration status (October 2026)

These states and D.C. use their own funds to cover people regardless of immigration status. Children's coverage has mostly held, but adult coverage is shrinking: California closed full-scope Medi-Cal to new adults 19 and older with unsatisfactory immigration status on January 1, 2026, ended full-scope dental for those adults on July 1, 2026 (emergency dental is still covered), and plans a monthly premium for ages 19–59 starting no sooner than July 1, 2027 (DHCS Medi-Cal changes page). Illinois ended its program for adults 42–64 in July 2025, Minnesota ended adult coverage in January 2026, and D.C. now enrolls only adults 21–25 and plans to end adult coverage by October 2027. Washington closed its adult program to new enrollment, and federal Apple Health eligibility changes take effect October 1, 2026 (Washington HCA).

Programs change with each state budget. Before you apply, confirm the current rules with your state Medicaid agency or a free navigator at localhelp.healthcare.gov.

How Do I Get Care at Community Health Centers?

To get care at a community health center, search by zip code and walk in; you don't need an SSN or insurance. Federal rules say no patient can be denied care for inability to pay, and discounts depend only on income and family size, with a full discount at or below 100% of the poverty line.

What they offer:

• Primary care (checkups, sick visits, chronic disease management)
• Dental care
• Mental health and substance use services
• Prenatal and OB/GYN care
• Prescription assistance
• Translation services

Under HRSA's sliding fee discount rules, patients at or below the federal poverty line get a full discount (some centers charge a small nominal fee), and patients up to 200% of it get partial discounts. No one is turned away for inability to pay.

Find your nearest health center: findahealthcenter.hrsa.gov — enter your zip code.

Hospital bills: ask for financial assistance

Nonprofit hospitals must have a written financial assistance policy, publish it, and provide emergency care without discrimination, under IRS section 501(r) rules. Ask the billing office for the application; the federal rules don't list an SSN or immigration status as a requirement, so the hospital's own policy decides what you need to show.

Can I Buy Private Health Insurance Without an SSN?

Yes. You can buy a private health plan directly from an insurer, outside HealthCare.gov, at full price, and no federal law requires an SSN to buy one. Ask whether the insurer's application takes an ITIN. Plans sold outside the Marketplace get no premium tax credits, so expect to pay 100% of the premium.

What to look for

• Individual or family plans sold directly by insurers (not through HealthCare.gov)
• Short-term health plans — lower premiums but limited coverage, high deductibles, and often no coverage for pre-existing conditions. Best as a bridge, not long-term coverage.
• Health-sharing ministries — not insurance, and they can deny claims; approach with caution
• Job-based plans — if your employer offers health insurance, you can enroll regardless of immigration status

Can ITIN Holders Use the ACA Marketplace?

It depends on immigration status, not the ITIN. Lawfully present immigrants, including many visa holders who file taxes with an ITIN, can buy HealthCare.gov plans; from January 1, 2027, only 4 groups get premium tax credits. Undocumented immigrants and DACA recipients can't enroll, even at full price, but can apply for eligible family members.

HealthCare.gov states that undocumented immigrants can't get Marketplace coverage but may apply on behalf of family members who qualify. That holds even if you've lived in the U.S. for years, pay federal taxes with an ITIN, or have U.S.-citizen children.

Under Public Law 119-21, premium tax credits are limited to U.S. citizens, green-card holders, Cuban/Haitian entrants, and COFA migrants starting January 1, 2027. Refugees, asylees, TPS holders, and other lawfully present immigrants can still buy plans at full price, and DACA recipients can't enroll — see our ACA Marketplace for immigrants guide for who keeps subsidies in 2027 and HealthCare.gov's list of immigration statuses that qualify.
