Medicaid covers medical, dental, vision, and mental health services, but what is included varies significantly by state and by which Medicaid program you are in

Medicaid is not a single insurance plan — it is a joint federal and state program, which means each state designs its own coverage. Two people with Medicaid in different states may have different benefits. Even within one state, a child in Medicaid may have different coverage than an adult, or someone in a managed care plan may have different coverage than someone in fee-for-service Medicaid. The core services are similar across states, but the details matter when you need care.

Your state's Medicaid program covers hospital stays, doctor visits, prescription medications, and emergency services for all members. Beyond that baseline, coverage depends on which category of Medicaid you are in — whether you are a child, a parent, pregnant, elderly, or disabled — and whether your state has chosen to expand its program. Some states cover dental work and eyeglasses; others do not. Some cover mental health treatment at no cost; others require a copay.

Key Takeaways

  • Every state's Medicaid covers hospital care, doctor visits, emergency services, and prescription drugs, but the specific services and copays vary by state.
  • Medicaid coverage differs by category: children, pregnant people, parents, elderly people, and disabled people may have different benefits in the same state.
  • Dental, vision, and mental health coverage are optional for states to provide, so availability depends on where you live.
  • You can find your state's specific coverage by contacting your state Medicaid office or reviewing the member handbook you receive when you are enrolled.

Services all state Medicaid programs must cover

Federal law requires every state Medicaid program to cover inpatient hospital services (overnight stays), outpatient hospital services (emergency rooms and same-day procedures), physician services (doctor visits), laboratory and X-ray services, home health services (nursing and aide care at home), and nursing facility services (long-term care in a facility). These are the floor — the minimum every state must pay for.

Medicaid also covers prescription medications, though the list of covered drugs and any copays you owe vary by state. Most states cover preventive services like vaccines and cancer screenings at no cost to you. Transportation to medical appointments is covered in most states if you have no other way to get there.

Emergency services are covered everywhere, regardless of whether you are in-network or out-of-network. If you go to an emergency room, Medicaid will pay for the emergency care itself, though you may owe a copay depending on your state.

Services states can choose to cover

Dental services are optional for states to provide. Some states cover routine cleanings, fillings, and extractions for all Medicaid members. Others cover dental only for children or pregnant people. Some states cover nothing. You will know what your state covers when you receive your member handbook or by calling your state Medicaid office.

Vision services including eye exams and eyeglasses are also optional. Most states cover eye exams and one pair of glasses per year for children. Coverage for adults varies widely — some states cover it, others do not. Contact lenses are rarely covered.

Mental health and substance use treatment is a required service, but the scope varies. All states must cover inpatient psychiatric hospital stays and outpatient mental health visits. Some states cover therapy and counseling at no cost; others charge a copay. Medication for mental health conditions is usually covered.

Rehabilitation services like physical therapy, occupational therapy, and speech therapy are covered, but the number of visits per year may be limited. Durable medical equipment — wheelchairs, oxygen, diabetic supplies — is covered, though you may need prior approval from your state before the equipment is ordered.

Copays and cost-sharing in Medicaid

Medicaid is designed to be low-cost or free for people with low income. Most states charge no copay for preventive services, emergency care, or hospital stays. However, many states do charge small copays for doctor visits, prescription drugs, or non-emergency services. A copay might be $1 to $5 per visit or per prescription, depending on your state and the type of service.

Pregnant people and children under 19 cannot be charged copays in any state — this is a federal rule. Adults may face copays, but the amount is capped: your state cannot charge more than 5 percent of your household income per year in total copays and other cost-sharing.

If you cannot afford a copay, tell the provider or the Medicaid office. Some states waive copays for people with very low income or for certain services.

Differences between Medicaid categories

Medicaid covers different groups of people, and each group may have slightly different benefits. Children are covered under a program called CHIP (Children's Health Insurance Program) in some states, or under regular Medicaid in others. Children's coverage is usually broader than adult coverage — most states cover dental and vision for children even if they do not for adults.

Pregnant people and new parents have coverage that includes prenatal care, delivery, and postpartum care. Some states extend coverage for a full year after birth; others cover only 60 days. Elderly people (usually 65 and older) may be on both Medicaid and Medicare, and the two programs coordinate to cover costs. Disabled people may have access to more services, including personal care attendants and home modifications, depending on the state.

How to find out what your state covers

Your state Medicaid office publishes a member handbook that lists exactly what is covered, what copays you owe, and how to find in-network providers. You should receive this handbook when you are enrolled. If you did not, you can request it by phone or download it from your state's Medicaid website.

The fastest way to get a specific answer is to call your state Medicaid office directly. They can tell you whether a particular service — say, physical therapy or an eye exam — is covered under your category of Medicaid and what you will owe. You can also ask your doctor's office; they often know what Medicaid covers in your state.

Your state's Medicaid website usually has a provider search tool where you can find doctors, dentists, and mental health providers in your area who accept your Medicaid plan.

Managed care versus fee-for-service Medicaid

Some states deliver Medicaid through managed care plans — insurance companies that contract with the state to cover Medicaid members. Others use fee-for-service, where the state pays providers directly. The core benefits are the same, but managed care plans may have different copays, different provider networks, or different rules about which services need prior approval.

If you are in a managed care plan, your plan's member handbook will show what is covered. If you are in fee-for-service Medicaid, your state's handbook applies. You can usually choose which managed care plan you want to join, or you can ask to stay in fee-for-service if your state offers that option.

Frequently Asked Questions

Does Medicaid cover prescription drugs?

Yes, all states cover prescription medications through Medicaid. The list of covered drugs varies by state, and some states charge a small copay per prescription. If your doctor prescribes a drug that is not on your state's list, you can ask your state Medicaid office for an exception, or your doctor can request prior approval.

Does Medicaid cover dental work?

It depends on your state. Most states cover dental for children, but coverage for adults varies widely. Some states cover routine care like cleanings and fillings; others cover only emergency extractions. Contact your state Medicaid office or check your member handbook to learn what your state covers.

Does Medicaid cover mental health treatment?

Yes, all states must cover mental health services including therapy, counseling, and psychiatric care. Inpatient psychiatric hospital stays are always covered. Outpatient mental health visits are covered, though some states charge a small copay. Medication for mental health conditions is usually covered with no copay.

Will I have to pay copays for everything?

No. Preventive services like vaccines and cancer screenings are free in all states. Emergency care is covered. Pregnant people and children under 19 cannot be charged copays.

What if my state does not cover a service I need?

Some states have programs that cover additional services for people with disabilities or chronic conditions. Your doctor can also help by submitting a request for prior approval or medical necessity.
