Your state runs Medicaid, not the federal government, so you contact the office in your state

Medicaid is a joint program between the federal government and each state, but your state Medicaid agency is the office that actually processes your information, answers questions about your coverage, and handles disputes. The federal government sets the rules, but your state decides how to run the program within those rules — which means the office you call or visit depends on where you live, not on a national phone number.

Each state has one main Medicaid agency, though it may have a different name. Some states call it the Department of Health and Human Services, others call it the Department of Social Services, and a few use other titles. The agency's job is to determine who gets Medicaid in your state, process paperwork, manage claims, and answer questions about coverage and benefits.

You may also need to contact your state's Medicaid managed care plan if your coverage is through one — but your state agency is the first place to start for questions about the program itself, may be able to access, or how to report a problem.

Key Takeaways

  • Every state has one Medicaid agency that handles enrollment, coverage decisions, and customer service for your state.
  • The agency's name and phone number vary by state — searching "[your state] Medicaid" or visiting your state health department website is the fastest way to find the correct contact.
  • You can reach most state Medicaid offices by phone, mail, or in-person visit, though wait times and hours vary.
  • If you cannot reach your state office or disagree with a coverage decision, you have the right to file a formal appeal through your state's process.
  • Some states use managed care plans to deliver Medicaid, so you may need to contact both your state agency and your plan depending on your question.

How to find your state Medicaid office contact information

The fastest way is to search "[your state name] Medicaid" in a search engine. This will usually take you to your state's official Medicaid website, which lists phone numbers, mailing addresses, and office locations. You can also visit your state's health department website — Medicaid is usually run by the health or human services department — and look for a Medicaid section.

If you are not sure which state office to contact, the Centers for Medicare & Medicaid Services (CMS) maintains a list of state Medicaid agency contact information on its website. You can also call 1-800-MEDICARE (1-800-633-4227) and ask for your state Medicaid office number, though this line is primarily for Medicare questions.

When you find your state office, write down the phone number, mailing address, and any website portal where you can check your case status. Many states now have online portals where you can log in to view your coverage, upload documents, or check the status of a request without calling.

What to have ready before you call or visit

State Medicaid offices handle many calls and visits each day, so having your information organized before you reach out will make the conversation faster. Gather your Social Security number, date of birth, and any case or process number your state gave you. If your question is about a specific service or claim, have the date and details ready.

If you are calling about a coverage decision you disagree with, have the letter your state sent you in front of you. These letters explain why the decision was made and what steps you can take next. If you are reporting a change in your household — a new job, a move, a change in income — have the date and details of the change ready.

If you need an interpreter, many state offices can provide one over the phone or in person. When you call, tell the office staff that you need an interpreter and what language you speak. Some states also have translated materials available on their websites.

Phone, mail, and in-person options

Most state Medicaid offices accept calls during business hours, usually Monday through Friday. Wait times vary widely — some offices answer within a few minutes, while others may have waits of 30 minutes or longer, especially early in the month or after a holiday. If you reach a voicemail, leave your name, phone number, and a brief description of your question, and the office will call you back, though this may take several days.

You can also mail documents or letters to your state Medicaid office. The mailing address is on your Medicaid card, on your state's Medicaid website, or in the letters your state sends you. Mail is slower than a phone call — it typically takes one to two weeks for your state to receive and process a mailed document — but it creates a paper record of what you sent and when.

Many states have local Medicaid offices where you can visit in person. These offices are usually located in county health departments or social services buildings. In-person visits can be faster than phone calls if you have documents to show or need help filling out forms, but you may need to wait for an appointment or wait in line. Check your state's website to find the office nearest you and whether you need an appointment.

Online portals and self-service options

Many states now have online portals where you can log in with your Medicaid number or Social Security number to check your coverage, view claims, upload documents, and report changes without calling. These portals are usually free and available 24 hours a day. To use one, you typically need to create an account on your state's Medicaid website.

Online portals are useful for checking whether a claim was paid, viewing your coverage details, or uploading documents like proof of income. However, some questions still require a phone call or in-person visit — for example, if you disagree with a coverage decision or need to speak to someone about a complex situation.

If you do not have internet access or are not comfortable using a computer, you can still reach your state office by phone or mail. Some states also have community health centers or social services offices that can help you use the online portal or submit documents on your behalf.

What to do if you disagree with a coverage decision

If your state Medicaid office denies a service, ends your coverage, or makes a decision you believe is wrong, you have the right to file a formal appeal. The process and timeline vary by state, but you usually have 30 to 60 days from the date of the decision letter to file. The letter your state sends you will explain how to appeal and what important date applies to you.

To appeal, you typically submit a written request to your state Medicaid office, either by mail, online portal, or in person. Include your name, case number, and a clear explanation of why you disagree with the decision. You may also be able to request a hearing where you can present your case to an independent reviewer.

If you need help with an appeal, you can contact a legal aid organization in your state — many offer free help with Medicaid appeals. You can find a legal aid office by searching "[your state] legal aid" or by calling the Legal Aid Corporation at 1-202-628-1903.

Managed care plans and additional contacts

Some states deliver Medicaid through managed care plans — private insurance companies that contract with the state to provide coverage. If your Medicaid is through a managed care plan, you will have a plan member ID card in addition to your state Medicaid number. For questions about specific services, claims, or providers in your plan, you contact the plan directly. For questions about your may be able to access or enrollment in Medicaid itself, you contact your state office.

Your state Medicaid office can tell you whether you are enrolled in a managed care plan and provide you with the plan's contact information. If you are unhappy with your plan, your state office can also explain how to change plans if your state allows it.

Some states also have Medicaid ombudsman offices — independent offices that help people resolve problems with their Medicaid coverage. If you are having trouble reaching your state office or getting a problem resolved, an ombudsman can advocate on your behalf. Search "[your state] Medicaid ombudsman" to see if your state has one.

Frequently Asked Questions

How long does it take to reach someone at my state Medicaid office?

Wait times vary by state and time of day. Some offices answer calls within a few minutes, while others may have waits of 30 to 60 minutes, especially early in the month or after holidays. If you cannot reach someone by phone, try calling early in the morning, later in the afternoon, or on a Wednesday or Thursday when call volume is often lower.

What if I cannot find my state Medicaid office online?

Start by visiting your state's health department website and looking for a Medicaid section. You can also search "[your state] Department of Health and Human Services" or "[your state] Department of Social Services" — Medicaid is usually run by one of these agencies. If you still cannot find it, call your county health department or social services office and ask for the Medicaid office number.

Can I contact Medicaid through a national phone number?

There is no single national Medicaid phone number because each state runs its own program. However, you can call 1-800-MEDICARE (1-800-633-4227) and ask for your state Medicaid office number. You can also visit the CMS website for a list of all state Medicaid agency contact information.

What happens if I mail a document to my state Medicaid office?

Mail typically takes one to two weeks to arrive and be processed. Include your name, case number, and a brief note explaining what you are sending. Keep a copy for your records. If the document is time-sensitive — for example, proof of income for a renewal — consider calling to confirm the important date before mailing.

Do I need to contact my state office or my managed care plan?

Contact your state office for questions about your may be able to access, enrollment, or coverage decisions. Contact your managed care plan for questions about specific services, claims, or which doctors are in your plan. If you are not sure which one to call, start with your state office — they can direct you to the right place.
