You apply for Medicaid through your state or county social services office, not through a federal agency

Medicaid is run by each state, so the office you contact depends on where you live. Most states have a single online portal or phone line where you start; some still require you to visit an office in person. The fastest way to find your state's entry point is to search "[your state] Medicaid application" or call 211, which is a free referral service that knows your local programs.

You cannot apply through Medicare, the federal government's health program for people over 65. You also cannot apply through Healthcare.gov, which handles private insurance subsidies under the Affordable Care Act. Medicaid is separate, and your state controls how and where you submit your information.

Some states let you start online and finish by phone or mail. Others require an in-person interview at a county office. A few states use contracted nonprofits to process applications. The rules differ enough that calling ahead or checking your state's website first saves time.

Key Takeaways

  • Contact your state's Medicaid office directly—search "[your state] Medicaid" or call 211 to find the phone number or website.
  • Each state runs its own Medicaid program, so the application process, required documents, and approval timeline vary by location.
  • You will need proof of income, residency, and citizenship or immigration status; bring recent pay stubs, tax returns, or a lease.
  • Most states process applications within 30 to 45 days, though some offer expedited review if you are in urgent need of coverage.
  • If you are denied, you have the right to request a hearing to challenge the decision, and your state must tell you how in the denial letter.

How to find your state's Medicaid office

Start by visiting your state's health or human services website. Search for "Medicaid" and look for a link labeled "Apply," "Application," or "How to Apply." Most state sites have a phone number and a web portal on the same page. If you cannot find it, call 211 and give them your state and county; they will give you the exact number and tell you whether your state accepts online applications.

Some states use a single statewide office; others route applications through your county social services department. A few states contract with third-party vendors to manage applications. The 211 operator will know which applies to you and can tell you the fastest route.

If you are homeless or do not have a mailing address, tell the office when you call. Most states have a process to accept applications from people without a permanent address, though you may need to provide a phone number or the address of a shelter or social service agency where mail can reach you.

Documents and information you will need to bring

Have these items ready before you start: proof of income (recent pay stubs, tax returns, or a letter from your employer), proof of residency (a utility bill, lease, or mortgage statement), proof of citizenship or immigration status (a birth certificate, passport, or green card), and your Social Security number. If you are applying for a child, you will also need their birth certificate.

If your income is irregular or you are self-employed, bring bank statements or tax returns from the past two years. If you receive benefits from another program—unemployment, Social Security, TANF, or SNAP—bring those award letters; they often count as proof of income and can speed up the process.

If you do not have all these documents, do not wait. Call the office and ask what you can submit instead. Many states will accept a signed statement from you if you do not have official documents, or they will give you time to find them after you submit your application.

Online, phone, and in-person application routes

Most states now offer online applications through a web portal. You create an account, enter your information, upload documents, and submit. The portal usually tells you immediately whether your application was received and gives you a case number to track progress. This is often the fastest route because you can apply at any time and do not have to wait for an office to open.

If you prefer to apply by phone, call your state's Medicaid office and ask to speak with an intake worker. They will ask you questions and fill out the form on their end. This takes 20 to 40 minutes depending on your situation. You will still need to mail or upload documents afterward.

Some states still require an in-person interview at a county office. If yours does, call ahead to schedule an appointment rather than showing up without one. Bring all your documents and be prepared to wait. A few states offer video interviews as an alternative to in-person visits.

What happens after you submit your application

Your state will send you a notice by mail or email within a few days confirming that your application was received. This notice includes a case number; save it. The office will then review your information and contact you if they need more documents or have questions. This review usually takes 30 to 45 days, though some states process faster.

If you are approved, you will receive a Medicaid card or a notice telling you how to access your coverage online. Coverage usually starts on the first day of the month after approval, though some states backdate coverage to the month you submitted your application if you meet the rules.

If you are denied, the notice will explain why and tell you how to request a hearing to challenge the decision. You have the right to a hearing in every state. The notice will include a deadline—usually 10 to 30 days—to request one. If you disagree with the decision, request the hearing even if you think you will not win; the process is free and you can bring someone to help you.

Special situations: expedited review and emergency coverage

If you need coverage urgently—for example, you are pregnant, have a serious illness, or are about to lose housing—ask the office whether your state offers expedited review. Some states can approve applications within 24 to 72 hours if you meet certain conditions. You have to ask for this; the office will not offer it automatically.

A few states offer emergency Medicaid that covers only hospital care and emergency services while your full application is being reviewed. This is rare and usually only for people with very low income, but it is worth asking about if you need immediate care.

If you are in a hospital or emergency room when you apply, tell the hospital social worker. They often have direct lines to the Medicaid office and can sometimes get a faster decision.

If you are denied or need to appeal

A denial notice must explain the reason—usually that your income is too high, you do not meet residency rules, or you did not provide required documents. Read the notice carefully. If the reason is missing documents, you can often resubmit them and ask for reconsideration without going through a full hearing.

If you want to challenge the decision, the notice will tell you how to request a hearing. You do this by writing a letter or calling the office by the deadline shown. You do not need a lawyer, though you can bring one. At the hearing, you can present documents, explain your situation, and ask questions. A hearing officer will make a new decision, usually within 30 days.

While you wait for a hearing, your application stays denied and you do not have coverage. Some states will cover you temporarily if you request it, but you have to ask.

Frequently Asked Questions

Can I apply for Medicaid online in every state?

Most states offer online applications, but not all. Some still require phone or in-person applications. Call 211 or your state's Medicaid office to find out which methods your state accepts. Even if your state has an online portal, you may still need to mail or upload documents afterward.

How long does it take to get approved?

Most states process applications within 30 to 45 days. Some are faster; a few take longer if they need more information from you. If you ask for expedited review and meet the criteria, some states can decide within 24 to 72 hours. Ask the office what the typical timeline is for your state.

What if I do not have a Social Security number?

You need a Social Security number to get Medicaid in most states. If you do not have one, contact your local Social Security office to apply. If you are undocumented, some states offer limited Medicaid coverage for emergency services only; call your state office to ask what is available.

Can I apply if I am homeless?

Yes. You do not need a permanent address to apply. Provide a phone number where you can be reached, or give the address of a shelter, social service agency, or trusted contact where mail can reach you. Tell the office you are homeless when you apply so they know to contact you by phone.

What if I miss the deadline to request a hearing?

Call your state's Medicaid office and explain that you missed the deadline. Some states will extend it if you have a good reason. Even if they will not, ask whether you can reapply; if your situation has changed, a new application may be approved where the first one was denied.
