Yes, homeless people can get Medicaid. Federal rules explicitly allow you to establish state residency “without a fixed address,” and no lease, utility bill, or permanent mailing address is required to apply. In the 40 or so states that expanded Medicaid under the Affordable Care Act, any adult earning up to about $22,025 a year in 2026 qualifies regardless of housing status. The real difficulty is usually the paperwork, not the eligibility rules, and there are workarounds for almost every piece of it.
Do You Meet the Income Rules
Medicaid eligibility is measured against the Federal Poverty Level. In 2026, the FPL for a single person in the contiguous 48 states is $15,960 per year, or about $1,330 per month.1ASPE. 2026 Poverty Guidelines Expansion states cover adults up to 138% of that number, roughly $22,025 a year or $1,835 a month for one person.2HealthCare.gov. Medicaid Expansion and What It Means for You If you have little or no income, you almost certainly fall well under the limit.
Household size affects the math. A single adult with no spouse or minor children who does not file taxes has a household size of one.3Medicaid.gov. Part 1: Household Composition
The Coverage Gap in Non-Expansion States
About 10 states have not expanded Medicaid. In most of them, a healthy adult with no minor children cannot qualify for Medicaid at any income level, because the pre-ACA rules still apply: coverage is limited mainly to children, pregnant women, parents of minor children, people with disabilities, and seniors. Marketplace subsidies only start at 100% of the FPL, so if you earn less than that in a non-expansion state, you can be too poor for subsidized private coverage and simultaneously ineligible for Medicaid. More than two million people nationally are stuck in this gap.
If you are in one of these states, community health centers that see patients regardless of insurance are usually the practical answer, along with any limited waiver programs your state may offer.
Proving Residency Without a Fixed Address
Federal regulations state that you establish Medicaid residency by living in a state and intending to stay there, “including without a fixed address.”4eCFR. 42 CFR 435.403 – State Residence States also cannot impose a minimum length of stay before you can apply. You do not need a lease or utility bill.
You will, however, need some way to receive mail. Acceptable options include a shelter address, a P.O. box, or the address of a friend, family member, or social service provider. Some states let you describe where you usually stay and sign a statement that you intend to remain in the state.5USICH. Medicaid Enrollment: Your Guide for Engaging People Experiencing Homelessness What matters is a reliable contact point, because a missed request for information can stall an application or terminate coverage.
What to Do If You’ve Lost Your ID
A current state ID or driver’s license is the easiest identification to use, but it is not the only option. An expired ID, a birth certificate, a Social Security card, or a letter from a shelter director or social worker confirming your identity can all work. Many states also verify identity electronically by checking existing databases rather than requiring you to hand over a physical document.6HHS.gov. Condensed Version of a Primer on How to Use Medicaid to Assist Persons Who Are Homeless to Access Medical, Behavioral Health, and Support Services
If you have no documents at all, start the application anyway. States will often begin processing and only ask for specific documents if electronic verification fails. Replacing lost ID can run in parallel with your Medicaid application, and shelter staff and outreach workers do this constantly.
Ask Someone to Handle the Paperwork for You
Federal rules let you appoint any person or organization as your authorized representative for your application, renewals, and all communications with the Medicaid agency.7eCFR. 42 CFR 435.923 – Authorized Representatives A shelter caseworker, social worker, or trusted friend can receive your notices, respond to information requests, and complete renewal forms in your place. The designation can usually be made electronically or by phone and stays in effect until you revoke it. If you do not have stable mail, this is one of the most valuable steps you can take.
How to Apply
You have four ways in, and none of them require a permanent address:
- Online, through your state’s Medicaid portal or HealthCare.gov, which will route you to Medicaid if you appear to qualify.8USAGov. How to Apply for Medicaid and CHIP
- By phone, using your state’s Medicaid enrollment line. Often the easiest option if you have a phone but not a computer.
- In person, at a local social services office, community health center, or many homeless service providers.
- By mail, using a paper application. This is the slowest route.
Once you apply, the agency has 45 days to decide, or 90 days if the application involves a disability determination.9eCFR. 42 CFR 435.912 – Timely Determination and Redetermination of Eligibility If you’re denied, the notice must explain why and how to request a fair hearing.10Medicaid.gov. Understanding Medicaid Fair Hearings Factsheet The appeal window is typically 60 to 90 days, depending on the state.
If You Need Care Before Your Application Is Approved
Presumptive eligibility can put you into temporary Medicaid coverage the same day. Qualified hospitals can screen you on the spot based on income and household size and enroll you immediately while your full application is pending.11Medicaid.gov. What Is Hospital Presumptive Eligibility and How Is It Different from Presumptive Eligibility for Pregnant Women and Children? Community health centers and some homeless service organizations can do the same in many states.
Presumptive coverage ends if you never file a full application, so treat it as a bridge, not a destination. For someone walking into an ER or a walk-in clinic uninsured, it is the fastest way to have care paid for.
Old Medical Bills
Federal law also requires states to cover qualifying medical bills from up to three months before your application date, provided you would have been eligible then and Medicaid covers the service.12eCFR. 42 CFR 435.915 – Effective Date More than two dozen states, however, have waivers that shorten or eliminate this retroactive window; some limit it to 30 days, some cover only from the month you applied. If you have outstanding medical bills, apply as soon as you can. Every day of delay potentially shrinks that window.
If You Are Not a U.S. Citizen
Immigration status changes the picture. Citizens and nationals who meet income rules qualify in any expansion state. Most lawful permanent residents must wait five years after getting their status before enrolling; refugees and people granted asylum are exempt from that wait, and many states cover lawfully residing children and pregnant women without it.
Undocumented immigrants generally cannot get full Medicaid, but every state must cover emergency medical services regardless of immigration status.13SSA.gov. Social Security Act 1903 An emergency medical condition includes situations where the absence of immediate care could seriously jeopardize your health, cause serious impairment to bodily functions, or involve emergency labor and delivery. This is limited to the emergency itself and does not cover follow-up care.
Staying Covered at Renewal
Approval is only half the job. Medicaid must be renewed periodically, usually every 12 months, and this is where many people experiencing homelessness lose coverage. The agency will first try to renew you automatically by checking tax records, wage databases, and other government data.14Medicaid.gov. Basic Requirements for Conducting Ex Parte Renewals of Medicaid Eligibility If the data confirms you still qualify, coverage continues with nothing required from you.
If the automatic check is inconclusive, a renewal form goes out by mail. That is the danger point. A form sent to a shelter address you no longer use, or a P.O. box you have not checked, will get you terminated if you do not respond. Three things protect you:
- Keep an authorized representative in place who can receive your mail and respond for you.
- Sign up for every electronic alert your state offers. Federal guidance encourages states to send renewal reminders by text, email, and phone in addition to mail.15Medicaid.gov. Overview: Medicaid and CHIP Eligibility Renewals
- Update your contact information the moment it changes, online or by phone.
What Medicaid Actually Pays For
Mandatory Medicaid coverage includes doctor visits, inpatient and outpatient hospital care, lab work, and home health services. Most states also cover prescription drugs, mental health treatment, substance use disorder services, dental care, and case management, though the specifics vary by state.16Medicaid.gov. Mandatory and Optional Medicaid Benefits
Two benefits are especially useful if you are unhoused and often go unused.
Rides to Medical Appointments
Every state Medicaid program must ensure that beneficiaries can get to and from covered medical services.17Medicaid.gov. Assurance of Transportation Non-emergency medical transportation must go to the nearest qualified provider by the least costly appropriate method, which might be a bus pass, a rideshare voucher, or a van service depending on your needs.18Centers for Medicare & Medicaid Services. Medicaid Transportation Coverage Guide Rides usually need to be scheduled in advance through a phone number your Medicaid plan provides.
Case Management and Housing Support
Many states offer targeted case management through Medicaid. A case manager can coordinate your care across multiple providers, help you keep your coverage, arrange transportation, complete paperwork, and connect you to housing programs, and can do so on the street or in a shelter.19Office of the Assistant Secretary for Planning and Evaluation. A Primer on Using Medicaid for People Experiencing Chronic Homelessness and Tenants in Permanent Supportive Housing A growing number of states also cover housing-related supports such as help with housing searches, security deposits, and tenancy services that help people stay in housing once they have it. These programs are not available everywhere.
Where to Get Help
You do not have to do this by yourself. Community health centers, in most cities and many rural areas, often have enrollment specialists on staff who can walk you through the application. Homeless shelters, outreach teams, and legal aid organizations also help with Medicaid applications and can help you replace lost ID at the same time. Federally funded navigator programs exist specifically to help uninsured people find and enroll in coverage.
If you need care before your application is processed, community health centers must see patients regardless of ability to pay, on a sliding scale based on income. For someone with no income, that scale may bottom out at zero. Getting seen and getting enrolled can happen in the same visit.
