Medicaid is a joint federal and state program, not a single national system

The most important thing to understand about Medicaid is that it is not one program run the same way everywhere. The federal government sets minimum rules, but each state designs and runs its own Medicaid program within those rules. This means may be able to access thresholds, covered services, payment rates to doctors, and application processes differ significantly from state to state.

Because of this structure, a person who qualifies for Medicaid in one state may not may have access to in another, and the services covered for the same condition can vary. For example, some states cover dental care; others do not. Some states expanded Medicaid to cover adults earning up to 138% of the federal poverty level; others did not. You always need to check your specific state's rules, not general national information.

The federal government funds part of each state's Medicaid costs and sets the baseline requirements. States fund the rest and decide how to administer the program within federal guidelines. This is why calling a national Medicaid hotline often leads nowhere — the person answering cannot tell you what your state covers or whether you may have access to.

Key Takeaways

  • Medicaid rules and coverage differ by state, so you must check your state's specific program, not national guidelines.
  • States decide who qualifies based on income and other factors, and these thresholds vary widely across the country.
  • The services Medicaid covers — such as dental, vision, or mental health care — depend on which state you live in.
  • Your state's Medicaid agency or your state health department website is the only source that can tell you what your state actually covers and whether you meet your state's rules.

Income limits are set by each state, not by the federal government

While the federal government sets a poverty line, states decide whether to use that line, exceed it, or stay below it when determining who qualifies for Medicaid. This is the single biggest source of confusion. A household income that qualifies in one state may disqualify you in another.

After the Affordable Care Act, the federal government offered to pay for states that expanded Medicaid to cover adults earning up to 138% of the federal poverty line. As of now, some states have adopted this expansion and others have not. In non-expansion states, Medicaid is often limited to children, pregnant people, parents of young children, elderly people, and people with disabilities — regardless of income thresholds.

The only way to know your state's income limit is to contact your state Medicaid agency directly or visit your state health department website. Do not assume national figures apply to you.

Medicaid covers more than just doctor visits

Federal law requires all state Medicaid programs to cover certain core services: inpatient hospital care, outpatient hospital services, emergency services, physician services, laboratory and X-ray services, and nursing facility care for people over 21. However, states can and do add coverage beyond these minimums.

Many states cover dental care, vision care, mental health services, substance use treatment, prescription drugs, and rehabilitation services. Some states cover these broadly; others limit them. For example, one state might cover all dental care, while another covers only emergency dental care. One state might cover vision exams and glasses; another might cover only exams.

You need to know what your specific state covers because it directly affects what you can use Medicaid to pay for. Your state Medicaid program or your state health department can provide a list of covered services.

Medicaid is not the same as Medicare

Medicaid and Medicare are two separate programs with different rules, funding sources, and purposes. This confusion causes real problems for people trying to understand their coverage.

Medicaid is a joint federal-state program for people with low income, regardless of age. It is funded by federal and state taxes. Medicare is a federal program for people age 65 and older, regardless of income, and for some younger people with disabilities or end-stage renal disease. It is funded through payroll taxes.

A person can have both programs at the same time — this is called "dual may be able to access." But the programs operate separately, cover different things, and have different rules. If someone tells you "Medicaid covers X," that does not mean Medicare covers X, and vice versa.

You cannot buy Medicaid or transfer it between states

Medicaid is not a product you can purchase. It is a government program you may be found to meet the rules for, based on income, family size, age, disability status, or other factors your state sets. You do not pay a premium to "get" Medicaid the way you might pay for private insurance.

If you move to a different state, your Medicaid coverage from your old state does not follow you. You must apply for Medicaid in your new state under that state's rules. Your new state may find you ineligible even if you may have access to in your old state, or it may cover different services. Some states have processes to help people transition coverage when they move, but you need to contact your new state's Medicaid agency to find out what applies to you.

During the COVID-19 pandemic, the federal government paused disenrollment from Medicaid, meaning people could not lose coverage just because they moved or circumstances changed. That pause ended in 2023, so states have resumed normal enrollment and disenrollment processes. If you move or your situation changes, contact your new state's Medicaid agency promptly.

Medicaid pays providers directly; you do not receive the money

When you use Medicaid, the program pays your doctor, hospital, pharmacy, or other provider directly. You do not receive a check or reimbursement. This is different from some other insurance, where you might pay out of pocket and then submit a claim for reimbursement.

When you go to a doctor or pharmacy, you show your Medicaid card. The provider bills Medicaid. Medicaid pays the provider according to the payment rate your state has set. You typically pay nothing, though some states charge small copayments for certain services.

Not all providers accept Medicaid. Some doctors, dentists, and other providers do not participate in Medicaid because the payment rates are lower than private insurance or they choose not to. If you have Medicaid, you need to find a provider who accepts it in your area. Your state Medicaid program can provide a list of participating providers.

Medicaid may be able to access can change if your income or family situation changes

Medicaid is not permanent coverage. If your income rises above your state's limit, you may lose Medicaid. If your family size changes, your may be able to access may change. If you turn 19 or 21 (depending on your state's rules for young adults), you may lose coverage.

You are responsible for reporting changes to your state Medicaid agency. If you do not report a change and you no longer meet the rules, your coverage can be terminated, and you may be asked to repay benefits you received while ineligible. Some states have grace periods or allow you to keep coverage for a short time after income changes, but this varies.

If your circumstances change — you get a job, lose a job, have a baby, get married, move — contact your state Medicaid agency to report the change. This protects you from unexpected disenrollment and ensures you stay covered if you still may have access to.

Frequently Asked Questions

Does Medicaid cover prescription drugs?

Most states cover prescription drugs through Medicaid, but the specific drugs covered and any copayments vary by state. Some states cover all FDA-approved drugs; others maintain a formulary (a list of covered drugs). Contact your state Medicaid program to find out what drugs are covered and what you will pay.

Can I use Medicaid at any hospital or doctor?

No. You must use a provider who accepts Medicaid in your state. Not all providers participate. Your state Medicaid program maintains a directory of participating providers, or you can call your state Medicaid agency to find a doctor or hospital near you that accepts Medicaid.

What happens to my Medicaid if I move to another state?

Your coverage ends when you move. You must apply for Medicaid in your new state under that state's rules and income limits. Your new state may find you ineligible or cover different services. Contact your new state's Medicaid agency as soon as you move to understand your options.

Do I have to pay back Medicaid if I receive it and then become ineligible?

Generally, no — Medicaid is not a loan. However, if you received Medicaid while ineligible because you did not report a change in income or family size, your state may pursue recovery. Some states are more aggressive about this than others. Report changes promptly to avoid this situation.

Is there a Medicaid program for people with higher incomes?

In expansion states, Medicaid covers adults earning up to 138% of the federal poverty line, which is higher than traditional limits. In non-expansion states, Medicaid remains limited to specific groups. If you do not may have access to for Medicaid, you may be able to purchase private insurance through the Health Insurance Marketplace. Contact your state health department or visit Healthcare.gov to explore options.
