Medicaid is a joint federal and state program that pays for healthcare for people with low income

Medicaid is not a single national program. The federal government sets basic rules, but each state runs its own Medicaid program and decides who gets coverage, what services are covered, and how much doctors and hospitals are paid. This means the program you join in one state works differently from the one in another state — the income limits are different, the covered services are different, and the process to enroll is different.

When you enroll in Medicaid, the state pays healthcare providers (doctors, hospitals, pharmacies, mental health clinics) directly for your care. You do not pay a premium in most cases, though some states charge small copays when you use services. The state keeps a record of your coverage, and you receive a card or number to show providers so they know to bill Medicaid instead of you.

Medicaid covers a wide range of services: doctor visits, hospital stays, prescription drugs, mental health treatment, dental care (in some states), vision care, and long-term care in nursing homes. The exact list depends on which state you live in and which Medicaid program you are in — there are several types, including traditional Medicaid, Medicaid managed care, and expansion Medicaid.

Key Takeaways

  • Medicaid is run by each state separately, so income limits, covered services, and enrollment processes vary significantly by location.
  • When you are enrolled, Medicaid pays providers directly for your care, and you typically do not pay a monthly premium.
  • You must report changes in income, household size, or address to keep your coverage active, because Medicaid may be able to access is checked regularly.
  • Each state has its own enrollment process, but you can start by contacting your state Medicaid office or using the federal healthcare marketplace.
  • Medicaid covers many services, but which ones are covered depends on your state and which type of Medicaid program you are in.

How income limits and household size determine who can enroll

Each state sets its own income limit for Medicaid. In most states, you can enroll if your household income is below a certain percentage of the federal poverty line — but that percentage varies. Some states cover people at 100% of the poverty line, others at 138%, and some at even lower levels. A few states have not expanded their Medicaid programs at all, which means working-age adults without children may not be able to enroll no matter how low their income is.

Your household size matters because income limits are based on how many people depend on that income. A single person with $1,500 a month might may have access to in one state but not another. A family of four with the same total income might may have access to in a different state. You can find your state's current income limits by contacting your state Medicaid office or checking its website.

Some groups have different rules. Children, pregnant people, and seniors often have higher income limits than working-age adults. People who are blind or disabled may also have different limits. If you fall into one of these groups, you might may have access to even if your income is above the standard limit for your state.

What happens after you enroll and how coverage stays active

Once you enroll, your state Medicaid office sends you a card or notice with your member ID number. You show this to doctors, hospitals, and pharmacies when you receive care. The provider bills Medicaid directly, and Medicaid pays them. You do not have to pay upfront in most cases, though some states charge small copays (usually $1 to $5 per visit or prescription).

Medicaid coverage is not permanent. Your state checks your may be able to access regularly — usually once a year, but sometimes more often. You must report changes in your income, household size, address, or immigration status. If you do not report changes, your coverage can end without warning. If your income increases above your state's limit, you will lose coverage. If someone moves out of your household, you must report that too.

Some states have continuous enrollment periods where coverage does not end as long as you stay may be able to access. Other states end coverage every 12 months and require you to re-enroll. A few states have special rules for children — their coverage may last longer than an adult's. Check with your state Medicaid office to learn when your coverage will be reviewed and what you need to do to keep it active.

The difference between traditional Medicaid and managed care plans

In traditional Medicaid, you can see any doctor or hospital that accepts Medicaid. There is no network, no gatekeeper, and no referral requirement. You show your Medicaid card, and the provider bills the state directly. This is how Medicaid worked for decades, and it still exists in some states and for some groups of people.

In Medicaid managed care, your state contracts with insurance companies to manage your care. You are assigned to (or you choose) a managed care plan, similar to a private health insurance plan. You have a network of doctors and hospitals, and you may need a referral to see a specialist. The managed care plan receives a fixed payment from the state each month to cover your care, and they handle billing and claims. Most states now use managed care for at least some Medicaid members.

The main difference from your perspective is choice and access. Traditional Medicaid gives you more freedom to choose providers. Managed care plans may have narrower networks but often include extra services like transportation to appointments or care coordination. Ask your state which type of Medicaid you will be in when you enroll, because it affects which doctors you can see.

What services Medicaid covers and what it does not

Medicaid must cover certain services in every state: doctor visits, hospital stays, emergency care, lab tests, X-rays, and family planning. But beyond that, each state decides what else to cover. Most states cover prescription drugs, mental health treatment, and dental care for children. Many cover dental care for adults, vision care, and hearing aids, but not all.

Long-term care in nursing homes is a major Medicaid service. Medicaid pays for nursing home care when Medicare runs out, and it is the largest payer for nursing home residents in the United States. However, you must spend down your savings to a very low level before Medicaid will pay for a nursing home — the exact amount varies by state.

Services Medicaid typically does not cover include cosmetic surgery, most fertility treatments, and some experimental drugs. If a service is not covered by your state's Medicaid program, you are responsible for the full cost. Before you have a procedure or fill a prescription, ask your doctor or pharmacist whether Medicaid covers it in your state.

How to enroll and where to start

The process to enroll in Medicaid is different in every state. Some states let you apply online, by mail, or in person. Others require you to apply through a specific office or agency. The fastest way to find out how to enroll in your state is to call your state Medicaid office directly or visit its website — search for "[your state] Medicaid" to find the right number and website.

You can also enroll through the federal healthcare marketplace at Healthcare.gov if your state participates. The marketplace can determine whether you may have access to for Medicaid or for tax credits to buy private insurance. If you are applying for the first time, the marketplace may be easier because it handles the initial screening.

When you apply, you will need to provide proof of income (pay stubs, tax returns, or a letter from your employer), proof of citizenship or immigration status, and proof of where you live. Some states ask for more documents. Ask your state Medicaid office what documents you need before you apply, so you can gather them in advance and speed up the process.

What to do if your coverage ends or you disagree with a decision

If your Medicaid coverage ends, you have the right to know why. Your state must send you a notice explaining the reason and telling you how to appeal. Common reasons include income increase, failure to report a change, or missing a renewal deadline. If you believe the decision is wrong, you can request a hearing to challenge it.

The appeal process varies by state, but you usually have 30 to 60 days from the date on the notice to file an appeal. You can appeal in writing, by phone, or in person, depending on your state's rules. During the appeal, you can present documents or testimony to show that you still may have access to. If you win the appeal, your coverage is restored, usually back to the date it ended.

If you need help with an appeal, contact your state's legal aid office or a local community health center. Many offer free help with Medicaid appeals. Do not ignore a notice that your coverage is ending — act quickly, because you have a limited time to appeal.

How Medicaid interacts with other insurance and programs

If you have both Medicaid and Medicare (because you are 65 or older, or disabled), you are called dual may be able to access. Medicare is your primary insurance, and Medicaid pays some of your Medicare costs and covers services Medicare does not cover. The coordination between the two programs is complex, and you should ask your state Medicaid office how it works in your situation.

If you have employer health insurance and Medicaid at the same time, Medicaid is usually the secondary payer. Your employer insurance pays first, and Medicaid covers costs that your employer insurance does not cover. This can happen if your employer offers insurance but it is very expensive, or if you work part-time and earn low wages.

If you receive Supplemental Security Income (SSI) or Temporary Assistance for Needy Families (TANF), you may be automatically enrolled in Medicaid in your state. Check with your state Medicaid office to confirm your coverage status if you receive either of these programs.

Frequently Asked Questions

Does Medicaid cover prescriptions?

Most states cover prescription drugs through Medicaid, but the list of covered drugs varies by state and changes regularly. Some states require you to try a cheaper drug first before covering a more expensive one. Ask your pharmacist whether your prescription is covered before you fill it, or call your state Medicaid office to check.

Can I choose my own doctor on Medicaid?

In traditional Medicaid, yes — you can see any doctor who accepts Medicaid. In a managed care plan, you must choose a doctor from the plan's network, though you can usually change doctors once a year or when you have a good reason. Ask your state which type of Medicaid you are in.

What happens to my Medicaid if I get a job?

If your income rises above your state's limit, you will lose Medicaid coverage. However, many states have work incentive programs that let you keep Medicaid for a few months after you start working, or that raise the income limit for working people. Tell your state Medicaid office that you got a job so they can explain your options.

Do I have to pay Medicaid back if my income increases?

No. Medicaid is not a loan. If you receive Medicaid while you may have access to, you do not have to repay it if your income increases later. You will simply lose coverage going forward. The only exception is for certain long-term care services in some states, which have estate recovery rules.

How long does it take to get approved for Medicaid?

Most states must make a decision within 30 to 45 days of receiving your application, though some states are faster. Emergency Medicaid for hospital care can be approved the same day. Ask your state Medicaid office how long the process typically takes in your area.
