Where to start: your state Medicaid office

You apply for Medicaid through your state's Medicaid agency, not through a federal office. Every state runs its own program with its own rules, income limits, and application process. The fastest way to find your state office is to search "[your state] Medicaid" or visit your state health department's website — most have a direct link to the Medicaid section.

Some states let you start your application online through their website. Others require you to visit an office in person, call a phone line, or mail in forms. A few states use a third-party contractor to handle applications, so the website you land on may not say "Medicaid" at the top — it might say your state's name plus "benefits" or "health coverage." The application itself asks for the same core information no matter which method you use.

Before you contact your state office, gather the documents you will likely need: proof of income (recent pay stubs, tax returns, or a letter from your employer), proof of citizenship or legal residency, proof of your Social Security number, and proof of your address. Not every state requires all of these, but having them ready speeds up the process.

Key Takeaways

  • You apply through your state Medicaid office, which you can find by searching "[your state] Medicaid" or visiting your state health department website.
  • Application methods vary by state — some accept online applications, others require phone calls or in-person visits, and a few still use mail-in forms.
  • Bring proof of income, citizenship or legal residency, Social Security number, and address when you apply, though requirements differ by state.
  • Processing times range from a few days to several weeks depending on your state and whether your application is complete.
  • If you are denied, you have the right to appeal and can request a hearing to explain your situation to a state official.

What information the application asks for

The application form collects basic household information: your name, date of birth, address, and Social Security number. It asks about everyone living in your household and their relationship to you, because Medicaid may be able to access depends partly on household size and total household income. You will need to list all sources of income for everyone in the household — wages, self-employment income, Social Security, unemployment benefits, child support, or any other money coming in.

The form also asks about your immigration status and citizenship. Medicaid is available to U.S. citizens and certain categories of legal immigrants, but not to undocumented immigrants in most states. Some states have expanded coverage to include undocumented immigrants in specific age groups or situations, so check your state's rules. You will be asked to provide a Social Security number or proof that you do not have one.

Many states ask about your current health coverage — whether you have insurance through an employer, a spouse's job, or another source. They also ask whether you are pregnant, disabled, or over 65, because these factors can change your income limits and the benefits you receive. Answer honestly; the state verifies income and household information through tax records and other databases.

How to submit your application

If your state offers online applications, you can usually start on the Medicaid website, create an account, and fill out the form section by section. Online systems typically save your progress, so you can stop and come back later. Once you submit, you will receive a confirmation number — save this. The state will contact you if they need more information or documents.

If you are applying by phone, call your state Medicaid office and ask to speak with an intake worker. They will ask you the same questions as the form and may be able to tell you on the spot whether you likely meet the income limit. Write down the date and time of your call and the name of the person you spoke with, in case you need to follow up.

For in-person applications, visit your local Medicaid office or county health department. Bring all your documents with you. An intake worker will help you fill out the form and can answer questions about what counts as income or what documents you need. In-person visits often move faster than mail or phone because the worker can spot missing information right away.

If you are mailing your application, send it to the address listed on your state's Medicaid website. Include copies (not originals) of your proof documents. Keep a copy for yourself and consider sending it certified mail so you have proof of delivery. Mail applications take longer — usually two to four weeks — because the state has to receive it, log it in, and then process it.

What happens after you submit

After the state receives your application, they will verify the information you provided. This means checking your income against tax records, confirming your citizenship or immigration status, and confirming your address. This verification step usually takes one to three weeks, though some states are faster and others slower depending on how busy they are.

If your application is complete and the state has everything they need, you will receive a decision letter in the mail. The letter will say whether you are approved, denied, or approved with conditions (for example, approved but only for emergency services). Keep this letter — you will need it to show doctors and hospitals that you have Medicaid.

If the state needs more information, they will send you a notice asking for specific documents or clarification. The notice will include a deadline — usually 10 to 30 days depending on your state. If you miss the deadline, your application may be denied, but you can reapply. If you submit the requested documents before the deadline, the state will continue processing.

Coverage usually starts on the first day of the month in which you were approved, or sometimes on the date you submitted your application if your state backdates coverage. Check your approval letter for the exact start date. You should receive a Medicaid card in the mail within one to two weeks of approval, though in some states you can use your approval letter at the doctor's office while you wait for the card.

If you are denied

A denial letter will explain why the state rejected your application — usually because your income is too high, you do not meet the citizenship requirement, or you did not provide required documents. The letter will also explain your right to appeal and how to request a hearing.

To appeal, you typically fill out a form or send a written request to your state Medicaid office within a set time frame (usually 30 to 60 days). At the hearing, you can present new information, bring documents, and explain your situation to a state official who was not involved in the original decision. You can bring someone with you to help — a family member, friend, or legal advocate.

If you were denied because of income, check whether your state has other programs you might be able to use instead, such as a state-only health plan for people who do not meet Medicaid limits, or a program for specific groups like pregnant women or children. Your state Medicaid office can tell you what other options exist.

Special situations: expedited processing and emergency coverage

If you are pregnant, a child, or in a medical emergency, some states offer expedited processing — your application is reviewed within days instead of weeks. Ask your state office whether expedited processing is available for your situation and what you need to do to request it.

Some states also offer emergency Medicaid coverage while your regular application is being processed. Emergency Medicaid covers only emergency room visits and emergency services, not routine care, but it can protect you from large bills if something urgent happens before your regular coverage starts. You do not have to do anything special to get emergency coverage — the state automatically considers you for it when you apply.

If you are homeless or do not have a permanent address, you can still apply. Use a shelter address, a friend's address, a post office box, or a community center address as your mailing address. Tell the intake worker that you are homeless so they know how to reach you — some states have special procedures for homeless applicants.

Keeping your coverage active

Once you are approved, your Medicaid coverage lasts for a set period — usually one year, though some states use different renewal periods. Before your coverage ends, the state will send you a renewal notice asking you to confirm that your household and income information is still the same. You must respond by the deadline or your coverage will end.

If your income, household size, or address changes during the year, report it to your state Medicaid office. Some changes require you to reapply or may affect your coverage. For example, if your income increases above the limit, you may lose coverage, but if you have a baby or someone moves into your household, you may become may be able to access again or your benefits may change.

Frequently Asked Questions

How long does it take to get approved for Medicaid?

Most states aim to process applications within 30 days, but the actual time ranges from a few days to several weeks depending on how busy the office is and whether your application is complete. Online and in-person applications usually move faster than mail. If the state needs more documents from you, the clock resets when you submit them.

Can I use Medicaid before I receive my card?

Yes. Once you are approved, you can show your approval letter to doctors and hospitals. Many providers will accept the letter as proof of coverage while you wait for your card to arrive in the mail. Call ahead to confirm that your provider accepts this, since policies vary.

What if I do not have a Social Security number?

You can still apply for Medicaid. Your state will ask you to sign a statement saying you do not have a Social Security number, and they will assign you an identification number for Medicaid purposes. Bring whatever identity documents you have — a passport, birth certificate, or state ID.

Do I have to reapply every year?

Yes, most states require you to renew your Medicaid coverage once a year. The state will send you a renewal form or notice before your coverage expires. You must respond by the deadline or your coverage will end. Some states have extended the renewal period to two years for certain groups, so check your approval letter for your renewal date.

What if my income changes after I am approved?

Report the change to your state Medicaid office as soon as possible. If your income increases above the limit, you may lose coverage, but you will receive notice before that happens. If your income decreases, you may become may be able to access for additional benefits. Some states have a grace period where small income increases do not affect your coverage right away.
