You apply for Medicaid through your state or county human services office, not through a federal agency
Medicaid is run by each state individually, so there is no single national application. You apply to the agency in your state that handles benefits — usually called the Department of Human Services, Department of Social Services, or Department of Health and Human Services. Some states let you apply online, by mail, or in person. Others require you to start online but finish in person. The fastest way to find your state's exact process is to search "[Your State] Medicaid apply" or call 211, which connects you to local benefits information for free.
The office you contact depends on where you live. If you live in a county that runs its own Medicaid program (some large urban counties do this), you apply to that county office. If your state runs the program statewide, you apply to the state office — but you can usually do it at a local branch. Either way, the person answering the phone can tell you which office handles your address and what documents you need to bring.
Key Takeaways
- Each state runs Medicaid differently, so the application process, timeline, and required documents vary by where you live.
- You apply to your state or county human services office, which you can find by calling 211 or searching your state's name plus "Medicaid apply".
- Most states now accept online applications, but some require you to finish the process in person or by mail after starting online.
- Bring proof of income, residency, citizenship or immigration status, and Social Security numbers for everyone in your household.
- Processing usually takes 30 to 45 days, though some states are faster and emergency Medicaid can cover you while you wait.
How to find your state's Medicaid office
The easiest method is to call 211 from any phone and tell them you want to apply for Medicaid. They will give you the phone number and address of the office that serves your address, and they can often tell you what documents to bring. This service is free and available in all 50 states.
If you prefer to search online, go to your state's official website and search for "Medicaid" or "apply for benefits." State websites usually have a link to the application portal or a phone number to call. Be careful to use the official state site (ending in .gov) rather than a private company's site, because some private sites charge fees or collect information they should not.
You can also visit a local office in person. Most counties have a human services office where staff can hand you an application, answer questions, and sometimes submit it on the spot. If you do not know where the office is, call 211 or your state's main benefits phone line.
Online, mail, and in-person application routes
Most states now have an online application portal where you create an account, fill out the form, and upload documents. The advantage is speed — you can apply at any time, and you get a confirmation number immediately. The disadvantage is that you have to scan or photograph your documents, and if something is missing, the office will contact you by mail or email, which can delay things.
Some states require you to finish the application in person even if you start online. This usually means you apply on the website, then get a notice telling you to visit an office with original documents. A few states still accept mail-in applications, though this is slower — you print the form, fill it out by hand, mail it in, and wait for a response.
In-person applications at a local office are often the fastest if you have all your documents ready. You can ask questions while you fill it out, the staff can check that everything is complete before you leave, and you walk out with a receipt showing the office received your application. Call ahead to ask if you need an appointment or if you can walk in.
Documents you will need to bring or upload
Every state requires proof of income, residency, and identity. The exact documents vary, but here is what most states ask for:
- Proof of income: recent pay stubs, tax returns, a letter from your employer, or a statement from your bank showing deposits.
- Proof of residency: a utility bill, lease, mortgage statement, or government mail with your current address.
- Proof of identity: a driver's license, passport, state ID card, or birth certificate.
- Proof of citizenship or immigration status: a birth certificate, passport, green card, or work permit.
- Social Security numbers for everyone in your household.
If you are applying for emergency Medicaid or are pregnant, some states waive the citizenship requirement temporarily. If you do not have a Social Security number, tell the office when you apply — some states can issue a temporary number or process your application without one while you get one.
If you do not have originals of these documents, bring what you have. The office can often help you get copies or tell you where to get them. Do not let a missing document stop you from applying — the office will work with you to find alternatives.
How long approval takes and what happens while you wait
Most states have 30 to 45 days to make a decision from the date they receive a complete application. Some states are faster — 10 to 15 days — and some take longer if they need to verify information. You will receive a notice in the mail telling you whether you were approved, denied, or need to send more information.
While you wait, you may be covered by emergency Medicaid in some states. Emergency Medicaid covers hospital stays, emergency room visits, and emergency surgeries for people who meet income limits but have not yet been approved for regular Medicaid. You do not have to apply separately for emergency coverage — the office will tell you if you may have access to when they process your application.
If you are approved, your coverage usually starts on the first day of the month after you apply, though some states backdate it to the date you applied. Your approval notice will tell you the start date and how long your coverage lasts. Most approvals are for 12 months, after which you will need to renew.
What to do if you are denied or need to reapply
If you receive a denial notice, read it carefully — it will explain why you were denied. Common reasons include income above the limit, not providing required documents, or not meeting citizenship requirements. The notice will also tell you how to appeal or request a hearing.
If you were denied because of missing documents, you can reapply and submit them. If you were denied because your income is too high, you may still be able to get coverage through the marketplace (healthcare.gov) or a state program for people with higher incomes. Call 211 to ask about other options.
If your situation has changed since you applied — you lost a job, your income dropped, or someone moved out of your household — you can apply again. You do not have to wait for your previous application to be fully processed. Each application is separate.
Frequently Asked Questions
Can I apply for Medicaid online in every state?
Most states have an online portal, but not all allow you to complete the entire process online. Some require you to finish in person or by mail. Call 211 or your state's Medicaid office to ask whether you can apply fully online or whether you will need to visit an office.
What if I do not have a Social Security number?
Tell the office when you apply. Some states can process your application without one and issue a temporary number, or they can hold your application while you get one. Do not delay applying because you do not have this number yet.
How do I know if my application was received?
If you applied online, you will get a confirmation number on the screen and usually an email receipt. If you applied in person, ask for a receipt before you leave. If you mailed it, send it certified mail so you have proof of delivery. You can also call the office after a week to confirm they received it.
Can I apply if I am homeless or do not have a permanent address?
Yes. Use a shelter address, a friend's address, a mailing address at a community center, or a post office box. Tell the office you are homeless — they may be able to help you find additional resources. Some states have programs specifically for people experiencing homelessness.
What if I applied but my circumstances changed before I was approved?
Contact the office and tell them about the change. If your income dropped or someone left your household, this may speed up your approval. If your income increased, it may affect whether you are approved. Either way, let them know so your application reflects your current situation.
