Medicaid covers doctor visits, hospital stays, and prescription drugs, but the exact list depends on your state and which Medicaid program you're in

Medicaid is not one program — it's a partnership between the federal government and each state, so what's covered in one state may not be covered in another. That said, every state Medicaid program must cover certain basics: doctor visits, hospital inpatient and outpatient care, lab work, X-rays, and family planning services. Most states also cover prescription drugs, mental health services, and dental care for children. Beyond those core services, coverage gets spotty. Some states cover dental for adults; others don't. Some cover vision care; many limit it to children only. Some cover physical therapy without limits; others require prior approval or cap the number of visits.

The amount you pay out of pocket also varies by state and by your income level. Many people on Medicaid pay nothing for doctor visits or prescriptions. Others pay small copays — typically $1 to $5 per visit or prescription. A few states charge small coinsurance amounts (a percentage of the cost) for certain services. Emergency room visits sometimes cost more than regular doctor visits. The key is that Medicaid is designed to keep costs low or zero for people with limited income, so even when there is a charge, it's usually small.

Key Takeaways

  • Every state covers doctor visits, hospital care, lab work, and family planning, but coverage for dental, vision, and therapy services varies by state.
  • Your out-of-pocket costs depend on your state and income level — many people pay nothing, while others pay small copays of $1 to $5.
  • Medicaid covers prescription drugs in most states, though some drugs may require your doctor to get prior approval before the pharmacy fills it.
  • Mental health and substance use treatment are covered in all states, but the number of visits or length of stay may be limited.
  • You can find your state's specific coverage list on your state Medicaid website or by calling your local Medicaid office.

Services every state Medicaid program must cover

Federal law requires every state to cover inpatient hospital care (staying overnight), outpatient hospital services (emergency room and same-day procedures), physician services (doctor visits), laboratory and X-ray services, and family planning services and supplies. These are the floor — the absolute minimum. If you're on Medicaid, you can count on being able to see a doctor, go to the hospital if you need to, and get basic tests done without Medicaid saying no.

Nursing facility care for people 21 and older is also federally required, as is early and periodic screening, diagnostic, and treatment (EPSDT) services for children under 21. EPSDT is broader than it sounds — it covers preventive care, dental, vision, hearing, and treatment for any condition a child is found to have during screening. This is one area where children's coverage is significantly more generous than adults'.

Services most states cover but aren't required to

Prescription drugs are covered in 49 states and Washington, D.C., but the specifics matter. Your state Medicaid program maintains a list of covered drugs called a formulary. If your doctor prescribes a drug not on the formulary, Medicaid may deny it, or your doctor may need to submit a prior authorization request explaining why that specific drug is necessary. Some states also use step therapy, meaning you have to try a cheaper drug first before Medicaid will pay for a more expensive one.

Mental health services and substance use disorder treatment are covered in all 50 states, but the scope varies. Some states cover unlimited outpatient therapy; others limit you to a certain number of visits per year. Inpatient psychiatric hospital stays are covered, but length of stay may be limited. Medication-assisted treatment for opioid use disorder (methadone or buprenorphine) is covered in all states.

Dental care for adults is covered in some states and not others — there's no federal requirement. When it is covered, it's often limited to emergency care (extractions and pain relief) rather than preventive or restorative work like cleanings and fillings. Dental for children is covered in all states as part of EPSDT. Vision care for adults is also optional; most states cover it only for children or only for people with specific conditions like diabetes. Eyeglasses are sometimes covered, sometimes not.

Rehabilitation and therapy services

Physical therapy, occupational therapy, and speech-language pathology are covered in all states, but how much and under what conditions varies widely. Some states cover these services with no visit limits if medically necessary. Others cap the number of visits per year or require prior approval before you start. Home health services (nursing care, therapy, or aide services in your home) are covered in all states for people who are homebound or have a medical reason they can't leave home.

Behavioral health services for children, including applied behavior analysis (ABA) for autism, are increasingly covered, but coverage rules differ by state. If your child needs therapy or behavioral services, ask your state Medicaid program what's covered and whether your provider needs approval before you start.

What Medicaid usually does not cover

Medicaid does not cover cosmetic procedures, experimental treatments not yet approved by the FDA, or services deemed not medically necessary. Routine foot care, hearing aids (though some states cover them for children), and long-term care in assisted living facilities are typically not covered — Medicaid covers nursing homes but not assisted living. Dental work beyond emergency care is often not covered for adults. Over-the-counter medications are not covered, though some states cover certain OTC items like nicotine replacement therapy if prescribed by a doctor.

Coverage for weight-loss surgery, fertility treatment, and bariatric procedures is rare and usually requires prior approval and documentation that you've tried other approaches first. If you need a service you're unsure about, ask your doctor to contact your state Medicaid program before you receive it — that way you'll know whether you'll be responsible for the bill.

How to find out what your state covers

Your state Medicaid program publishes a coverage guide, usually available on its website. Search "[your state] Medicaid covered services" to find it. The guide lists what's covered, what requires prior approval, and what the copays are. You can also call your state Medicaid office directly — the number is on your Medicaid card or on the state website. Have your Medicaid ID number ready, and ask specifically about any service you're considering.

If your doctor prescribes something and you're not sure whether Medicaid covers it, ask the doctor's office to check before the prescription is filled. Many offices have staff who handle insurance questions and can get an answer in a day or two. If Medicaid denies a service, you have the right to request a fair hearing to appeal the decision — your state Medicaid program can explain how.

Copays and out-of-pocket costs

Most people on Medicaid pay nothing for doctor visits or prescriptions. However, some states do charge small copays, and the amount depends on your income level. If you're at or near the federal poverty line, your copays are usually zero or very small ($1 per visit). If your income is higher but still low enough to may have access to for Medicaid, your copays may be a few dollars per service. Emergency room visits sometimes have a higher copay than regular doctor visits — typically $3 to $5 — though many states waive the copay if you're admitted to the hospital.

Copays for prescriptions vary by state and by the type of drug. Generic drugs usually have lower copays than brand-name drugs. If a copay would be a hardship for you, tell your doctor or pharmacist — some states have hardship exemptions that waive copays for people with very low income or chronic conditions.

Frequently Asked Questions

Does Medicaid cover dental work for adults?

It depends on your state. About half of states cover some dental services for adults, usually limited to emergency care like extractions and pain relief. Preventive care like cleanings and fillings are rarely covered. Check your state Medicaid website or call your state office to find out what's available where you live.

Will Medicaid pay for my prescription if my doctor prescribes a brand-name drug?

Medicaid will usually pay for a generic version if one exists. If your doctor prescribes a brand-name drug, Medicaid may deny it unless your doctor submits a prior authorization explaining why the generic won't work for you. Ask your doctor's office to handle this before you go to the pharmacy.

Does Medicaid cover mental health treatment?

Yes, all states cover mental health services including therapy and psychiatric care. However, some states limit the number of outpatient visits per year or require prior approval. Call your state Medicaid program or check your coverage guide to find out what's available and whether you need approval before seeing a therapist.

What happens if Medicaid denies a service my doctor says I need?

You have the right to appeal. Your state Medicaid program must provide you with a written explanation of why the service was denied and instructions for requesting a fair hearing. You can also ask your doctor to submit additional documentation supporting the medical need. Contact your state Medicaid office for details on how to file an appeal.

Are there copays for emergency room visits?

Many states charge a small copay ($3 to $5) for emergency room visits, but the copay is often waived if you're admitted to the hospital. Some states charge no copay at all. Check your state's rules or call your Medicaid office to find out what you'll owe.
