Where to apply depends on your state

You apply for Medicaid through your state's health department or social services agency, not through a federal office. Each state runs its own program with its own rules, income limits, and application process. Some states let you apply online, by mail, or in person at a local office. Others require you to start online. The fastest way to find your state's application is to search "[your state name] Medicaid apply" or visit your state health department's website directly.

A few states use a third-party contractor to handle applications. For example, some states contract with Conduent or Maximus to run their Medicaid intake. If you land on one of these sites, you are still applying for your state's Medicaid program — the contractor just processes the paperwork. The rules and coverage are the same.

If you cannot find your state's application online, call 211 (a free referral service) and give them your state and county. They can tell you the exact office to contact and whether that office accepts walk-ins or phone applications.

Key Takeaways

  • You apply through your state's health department or social services agency, and the process and deadlines vary by state.
  • Most states now accept online applications, though some still require you to mail documents or visit an office in person.
  • You will need proof of income, citizenship or immigration status, and residency — the exact documents depend on your state.
  • Processing typically takes 30 to 45 days, but some states are faster if you apply online and upload documents immediately.
  • 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.

What documents you need to gather before you start

Every state asks for proof of income, citizenship or immigration status, and where you live. Income proof usually means recent pay stubs, tax returns, or a letter from your employer. If you are self-employed, bring tax returns from the past two years. If you receive Social Security, unemployment, or child support, bring the award letter or a recent statement showing the amount.

For citizenship, you will need your birth certificate, passport, or naturalization papers. If you are not a U.S. citizen, you will need your immigration documents — a green card, visa, or work permit. Some states cover certain immigrants even without full legal status, but they still need to see your immigration paperwork to determine what you are covered for.

Proof of residency can be a utility bill, lease, mortgage statement, or mail from a government agency with your current address. It usually needs to be dated within the last 60 days. If you are homeless or living with someone else, most states have a way to document that — ask the application worker what they accept.

Write down the names and birthdates of everyone in your household, even if they are not applying. You will also need Social Security numbers for household members, though some states let you apply without them and add them later.

How to apply online

Most states now have an online portal where you create an account, fill out a form, and upload documents. The portal usually asks you to enter your income, household size, citizenship status, and whether you are pregnant, disabled, or caring for children. Answer honestly — the system uses these answers to determine which Medicaid category you might fit into and what income limit applies to you.

After you submit, the state sends you a confirmation number and tells you what happens next. Some states ask you to mail original documents or a signed form. Others process everything online if your documents are clear. Check your email and any mail from the state — they will contact you if they need more information, and if you do not respond within the deadline (usually 10 to 30 days), your application may be denied.

Keep your confirmation number and take screenshots of your application status page. If there is a problem later, you will need proof that you applied and when.

Applying by mail or in person

If your state does not have online applications or you cannot use the online system, you can request a paper application by phone or mail. Call your state's Medicaid office or visit a local social services office and ask them to mail you the form. Fill it out completely, sign it, and mail it back with copies of your documents.

Mail applications take longer — usually 45 to 60 days — because the state has to receive your envelope, scan your documents, and enter your information into their system. Send everything certified mail so you have proof of delivery. Keep copies of everything you send.

If you apply in person at a local office, bring all your documents with you and be prepared to wait. Some offices take walk-ins; others require an appointment. Call ahead to ask. An office worker can answer questions while you fill out the form and may be able to scan your documents on the spot, which speeds up processing.

What happens after you submit your application

The state has 30 to 45 days to make a decision, though some states are faster. During this time, a caseworker reviews your income, household size, and citizenship status against your state's Medicaid rules. If everything matches, you are approved. If something is unclear or missing, the state sends you a notice asking for more information. You usually have 10 to 30 days to respond.

If you are approved, the state sends you a Medicaid card or tells you that coverage starts on a specific date. Coverage usually begins on the first day of the month after you are approved, though some states backdate it to the month you applied if you were already may be able to access then.

If you are denied, the state sends a letter explaining why. The letter also tells you how to request a hearing to challenge the decision. You have the right to a hearing even if you disagree with the reason for denial.

If your application is denied or you need to appeal

A denial usually means your income was too high, you did not prove citizenship or residency, or you did not respond to a request for more information. Read the denial letter carefully — it explains the exact reason and what you would need to change to be approved.

You can request a hearing within a set time frame (usually 30 to 90 days, depending on your state). The hearing is a chance to present your case to someone other than the caseworker who denied you. You can bring documents, witnesses, or a representative to speak for you. Many legal aid organizations offer free help with Medicaid hearings — search "[your state name] legal aid" to find one near you.

You can also reapply if your situation changes. If you were denied because your income was too high, and you then lose a job or have a change in circumstances, you can apply again and your new income will be considered.

Special situations: expedited processing and emergency coverage

Some states offer expedited processing if you are pregnant, homeless, or facing a medical emergency. Expedited means the state tries to approve you within 7 days instead of 30 to 45. Ask the application worker or your state's Medicaid office whether you may have access to.

A few states offer emergency Medicaid coverage while your application is being processed. This covers only emergency room visits and hospital stays, not regular doctor visits or prescriptions. Emergency Medicaid is automatic in some states; in others, you have to ask for it. Check your state's rules or ask when you apply.

If you are applying for a family member who is in the hospital or nursing home, tell the application worker immediately. Some states prioritize these cases or can start coverage faster.

Frequently Asked Questions

Can I apply for Medicaid if I am not a U.S. citizen?

It depends on your immigration status and your state. Lawful permanent residents (green card holders) can usually apply. Some states cover certain other immigrants, such as refugees or people with work permits. Undocumented immigrants are generally not covered by regular Medicaid, though some states offer limited emergency coverage. Bring your immigration documents and ask the application worker what you are covered for.

How long does it take to hear back after I apply?

Most states take 30 to 45 days. If you apply online and upload all documents immediately, some states process faster — sometimes within two to three weeks. If the state asks for more information and you respond quickly, processing speeds up. If you do not respond to a request for documents, your application may be denied or delayed.

What if I do not have a Social Security number?

You can still apply. Some states let you apply without a Social Security number and add it later. Others require you to apply for one before they can approve you. Ask your state's Medicaid office what they need. If you are not may be able to access for a Social Security number, some states have workarounds — call 211 or your local social services office to ask.

Can I apply for my child even if I do not may have access to?

Yes. Children often have higher income limits than adults, so a child may be covered even if a parent is not. You can apply for your child alone, and the state will only look at the child's income and household size. Some states have separate programs for children with higher limits, such as the Children's Health Insurance Program (CHIP).

What if I move to a different state after I apply?

You will need to apply in your new state. Medicaid coverage does not transfer between states. If you are approved in your old state but move before coverage starts, contact that state's Medicaid office and ask them to cancel your application. Then apply in your new state right away. Some states have shorter processing times than others, so do not assume you will be covered immediately.
