Medicaid covers doctor visits, hospital stays, and prescription drugs, but the exact list depends on your state

Medicaid is not one program — it is 50 different programs run by states, each with its own coverage rules. What your state covers for adults may differ from what the state next door covers. The federal government sets a floor: certain services every state must cover. States can add more on top of that floor, and many do.

The core services every state Medicaid program must cover for adults include doctor visits, hospital inpatient and outpatient care, lab work, X-rays, nursing facility care, and home health services. Most states also cover prescription drugs, though the list of which drugs and how much you pay varies. Mental health and substance use treatment are covered in every state, though the number of visits or days may be limited.

What you actually pay out of pocket — copays, coinsurance, deductibles — also varies by state and sometimes by income level within your state. Some adults pay nothing. Others pay small copays for certain services. A few states charge higher amounts, though federal law caps what they can charge.

Key Takeaways

  • Every state must cover doctor visits, hospital care, lab work, and nursing facility services, but the scope and your out-of-pocket costs differ by state.
  • Prescription drug coverage is standard in most states, but which drugs are covered and how much you pay depends on your state's formulary and your income.
  • Mental health and substance use treatment are covered everywhere, though the number of visits or days allowed may be limited or require prior approval.
  • Dental, vision, and hearing services are optional for states to cover for adults, so check your state's specific rules before assuming they are included.
  • Your state's Medicaid website or your case worker can tell you exactly what is covered under your plan and what you will owe.

Services every state Medicaid program must cover

Inpatient hospital care covers a hospital stay when you need overnight treatment. This includes the room, meals, nursing care, and routine lab work done during your stay. It does not cover private-duty nursing or a private room unless medically necessary.

Outpatient hospital services cover treatment you receive at a hospital without staying overnight — emergency room visits, same-day surgery, imaging, and lab work. Physician services cover visits to a doctor's office or clinic, including preventive care like annual checkups and screenings. Laboratory and X-ray services are covered when ordered by a doctor. Nursing facility services cover skilled nursing care in a facility when you cannot manage at home — typically after a hospital stay or for someone with a chronic condition requiring daily nursing care.

Home health services cover nursing, therapy, and aide services delivered at your home when you are homebound or have a doctor's order for home-based care. Early and periodic screening, diagnosis, and treatment (EPSDT) is technically for children, but many states extend similar preventive screening to adults. Family planning services are covered in every state.

Prescription drugs and pharmacy coverage

Most states cover prescription drugs through Medicaid, but each state maintains a formulary — a list of which drugs are covered and at what cost to you. A drug on one state's formulary may not be on another's. Your state may cover a drug only if your doctor gets prior approval, or only after you try a cheaper alternative first.

Copays for prescriptions vary widely. Some states charge $1 to $3 per prescription. Others charge higher amounts or charge based on the drug tier (generic, brand-name, specialty). A few states charge no copay for prescriptions. Your state's Medicaid program or your pharmacy can tell you the exact copay before you fill a prescription.

If your doctor prescribes a drug that is not on your state's formulary, your doctor can request an exception. This usually takes a few days to a week. In the meantime, you may need to use a different drug or pay out of pocket and ask for reimbursement later if the exception is approved.

Mental health and substance use treatment

Every state Medicaid program covers mental health services and substance use disorder treatment. This includes outpatient therapy, psychiatric visits, inpatient hospitalization for mental health crises, and medication-assisted treatment (like methadone or buprenorphine for opioid use disorder).

The number of therapy visits or inpatient days may be limited. Some states cap outpatient mental health visits at 20 or 30 per year; others have no limit. Some require prior approval before you start treatment. A few states limit inpatient psychiatric stays to a certain number of days per year. Your state's Medicaid program can tell you the limits that apply to you.

Substance use treatment is covered the same way. Detoxification, residential treatment, outpatient counseling, and medication-assisted treatment are all covered services in every state, though the length of stay or number of visits may be limited. If you need treatment, call your state's Medicaid number or ask your doctor for a referral to a Medicaid-covered provider.

Services states may or may not cover

Dental care for adults is optional for states. Some states cover basic dental (cleanings, fillings, extractions). Others cover nothing. A handful cover major dental work like crowns or root canals. Check your state's Medicaid website or call your case worker to find out what dental coverage, if any, you have.

Vision care is also optional. Most states cover one eye exam per year and eyeglasses or contact lenses once per year. Some cover nothing. Hearing aids and hearing exams are optional too — coverage varies widely by state.

Therapy services like physical therapy, occupational therapy, and speech therapy are covered in most states, but the number of visits may be limited or require prior approval. Chiropractic care is rarely covered. Acupuncture is covered in some states and not others. Podiatry (foot care) is covered in some states for people with diabetes or other conditions; others do not cover it at all.

Durable medical equipment — wheelchairs, walkers, oxygen, CPAP machines — is covered in every state, but you may need prior approval and must use equipment from a Medicaid-approved supplier. Prosthetics and orthotics (artificial limbs, braces) are covered in most states.

What Medicaid does not cover

Medicaid does not cover cosmetic surgery, elective procedures with no medical necessity, or experimental treatments not yet approved by the FDA. It does not cover over-the-counter medications you buy without a prescription. It does not cover weight-loss surgery in most states, though some states cover it for people with severe obesity and related health conditions.

Medicaid does not cover long-term care insurance, life insurance, or disability insurance. It does not cover services from providers outside the United States. It does not cover fertility treatments or surrogacy in most states, though a few cover some fertility services.

If you need a service and are not sure whether it is covered, ask your doctor to check with your state's Medicaid program before you receive the service. This prevents surprise bills and helps you understand what you will owe.

How to find out what your state covers

Your state's Medicaid website lists covered services, though the language can be dense. A faster route is to call your state's Medicaid customer service line — the number is on your Medicaid card or on your state's Medicaid website. You can also contact your Medicaid case worker if you have one assigned.

If you are seeing a specific doctor or need a specific service, call that provider's office and ask whether they accept your Medicaid and whether the service is covered. Providers often know the coverage rules faster than you can find them online.

If you disagree with a coverage decision — for example, if Medicaid denies a service your doctor says you need — you have the right to appeal. Your Medicaid notice will explain how to file an appeal and the deadline to do so. Most states give you 30 to 60 days to appeal.

Frequently Asked Questions

Does Medicaid cover preventive care like annual checkups and cancer screenings?

Yes. Every state covers preventive services like annual physical exams, blood pressure checks, cholesterol screening, and cancer screenings (mammograms, colonoscopies, Pap smears). You typically pay nothing for these services. If your doctor orders additional tests based on the screening results, those are usually covered too.

Will Medicaid cover my prescription if my doctor prescribes a brand-name drug but a generic is available?

Most states require you to use the generic version first. If the generic does not work for you or causes side effects, your doctor can request an exception to use the brand-name drug. This usually takes a few days. In the meantime, ask your doctor if there is an alternative generic drug you can use.

Does Medicaid cover therapy or counseling for depression or anxiety?

Yes. Outpatient mental health visits are covered in every state. You may have a copay (usually $1 to $5 per visit) and may be limited to a certain number of visits per year, depending on your state. Call your state's Medicaid program or ask your doctor for a referral to a Medicaid-covered therapist or psychiatrist.

What happens if I need a service that is not covered by my state's Medicaid?

You can pay out of pocket, ask your doctor if there is a covered alternative, or appeal the coverage decision if you believe the service is medically necessary. Some providers offer payment plans or sliding-scale fees for uninsured or underinsured patients. You can also contact your state's Medicaid ombudsman for help understanding your options.

Does Medicaid cover emergency room visits?

Yes. Emergency room visits are covered in every state, whether or not the visit results in hospitalization. You may have a copay (usually $1 to $5), though many states waive the copay if you are admitted to the hospital. Go to the emergency room if you believe you have a medical emergency — do not delay because of cost.
