Medicaid covers emergency room visits, but what you pay depends on your state's rules and your specific coverage type

If you have Medicaid, you can go to the emergency room and Medicaid will pay the hospital for your care. You will not be turned away because you cannot pay. However, Medicaid does not cover every service you might receive there, and some states charge you a small fee when you arrive. The amount Medicaid pays the hospital, and what you owe, varies by state and by whether you are on traditional Medicaid or a managed care plan.

Emergency room coverage is one of the few services that Medicaid must cover in every state. Federal law requires it. But the details — what counts as an emergency, whether you pay a copay, how much the hospital gets paid — are set by each state.

Key Takeaways

  • Medicaid covers emergency room visits in all 50 states, and you cannot be denied care because you have no money to pay.
  • Some states charge a small copay (usually $1 to $5) when you arrive at the emergency room, even if you have Medicaid.
  • Medicaid pays the hospital directly, but only for services deemed medically necessary — elective procedures or non-emergency care may not be covered.
  • If you are on a Medicaid managed care plan, you may need to use a hospital in your plan's network, or you may face higher out-of-pocket costs.
  • What happens after the emergency room visit — hospital admission, follow-up care, prescriptions — depends on your specific Medicaid plan and state rules.

What the Emergency Room Visit Itself Costs You

Most states do not charge you anything when you walk into the emergency room with a Medicaid card. You show your card, and Medicaid covers the visit. However, some states do charge a copay — a small flat fee you pay at the time of service. These copays are typically $1, $2, $3, or $5 per visit. A few states charge higher amounts, but federal law caps what Medicaid can charge low-income people, so the fee is always small.

If you cannot pay the copay, the hospital cannot refuse to treat you. The copay is not a barrier to care. You can pay it later, or the hospital may waive it if you explain you have no money. Ask the front desk what your state's copay is before you are seen, so you know what to expect.

The copay covers the emergency room visit itself — the triage nurse, the doctor, the basic exam. It does not cover X-rays, blood tests, CT scans, or other tests the doctor orders. Those are billed separately, and Medicaid covers them as part of the emergency room claim.

What Medicaid Covers in the Emergency Room

Medicaid covers the cost of treating a medical emergency. That means the doctor's time, the nurse's time, the use of the room, basic supplies, and any tests or imaging the doctor orders to diagnose or treat the emergency. If you come in with chest pain, Medicaid covers the EKG, the blood work, the X-ray, and the doctor's evaluation. If you have a broken arm, Medicaid covers the X-ray and the setting of the bone.

Medicaid does not cover services that are not medically necessary for the emergency. If you go to the emergency room for a sore throat and the doctor does not order a throat culture or strep test, Medicaid still covers the visit and the exam. If you ask for a test the doctor does not think is necessary, Medicaid may not cover it, and you may be billed for it.

Medications given to you in the emergency room are covered. If the doctor prescribes a painkiller, antibiotic, or other drug while you are there, Medicaid pays for it. Prescriptions you take home are covered under your Medicaid prescription drug benefit, which varies by state and plan.

How Medicaid Managed Care Plans Handle Emergency Rooms

If you are on a Medicaid managed care plan — sometimes called an HMO or MCO — your coverage works slightly differently. Your plan has a network of hospitals and doctors. If you go to a hospital in the network, your copay and coverage are the same as traditional Medicaid. If you go to a hospital outside the network, you may pay more out of pocket, or the plan may refuse to pay.

However, federal law says that managed care plans must cover emergency room visits at any hospital, in or out of network, if the visit is truly an emergency. The plan cannot make you call ahead or get permission before you go. You go to the nearest emergency room, and the plan pays. The plan can only refuse to pay if it later decides the visit was not actually an emergency — for example, if you went to the emergency room for a minor cut that should have been treated at an urgent care clinic.

After the emergency room visit, if you are admitted to the hospital, your managed care plan's rules apply. If the hospital is in network, you stay. If it is out of network, the plan may transfer you to a network hospital, or it may pay for you to stay but at a higher cost to you. Ask your plan what happens next before you are discharged from the emergency room.

What Happens if You Are Uninsured or Your Medicaid Lapses

If you do not have Medicaid when you go to the emergency room, the hospital must still treat you. Federal law requires it. The hospital will bill you for the full cost, which can be thousands of dollars. However, you may be able to apply for Medicaid retroactively — going back up to three months before you applied — and Medicaid may cover the emergency room bill.

If your Medicaid ended and you did not know it, tell the hospital billing department immediately. Many states allow retroactive coverage for emergency services. The hospital can help you apply for Medicaid, and if you are found to be covered for that date, Medicaid will pay the bill instead of you.

If you think your Medicaid may have ended, contact your state Medicaid office or your managed care plan before you need the emergency room. You can renew your coverage or find out your status. Most states have a phone number on the back of your Medicaid card.

Ambulance Rides and Transport to the Hospital

Medicaid covers the cost of an ambulance if it is medically necessary. If you call 911 and an ambulance takes you to the hospital, Medicaid pays for the ambulance ride. You do not pay for it out of pocket. However, if you call a private ambulance or a medical transport service without a medical reason, Medicaid may not cover it.

Some states charge a small copay for ambulance rides — usually $0 to $5. A few states charge more. Ask the ambulance company or your state Medicaid office what the copay is in your state. If you cannot pay, the ambulance will still take you to the hospital.

If you drive yourself to the hospital or a friend drives you, there is no transport cost to Medicaid. Medicaid only pays for ambulances if they are called and used.

After the Emergency Room: Hospital Stays and Follow-Up Care

If the emergency room doctor admits you to the hospital, Medicaid covers the hospital stay. The copay for a hospital stay is different from the emergency room copay — it is usually higher and may be per day or per stay, depending on your state. Some states charge $0 for hospital stays. Others charge $100 to $300 per stay. Your Medicaid card or your plan paperwork will tell you what your copay is.

After you leave the hospital, follow-up care — doctor visits, physical therapy, home health care, prescriptions — is covered by Medicaid if it is medically necessary. However, you may have copays for doctor visits and prescriptions, depending on your state and plan. Ask your discharge planner or your doctor's office what your copays are before you leave the hospital.

If the hospital refers you to a specialist or a rehabilitation facility, make sure it is in your Medicaid plan's network if you are on a managed care plan. If it is out of network, ask your plan for permission before you go, or you may face a higher bill.

Frequently Asked Questions

Will Medicaid pay if I go to the emergency room for something that turns out not to be an emergency?

Yes. Medicaid pays based on what you thought at the time, not on what the doctor finds. If you had chest pain and went to the emergency room, and the doctor finds it was heartburn, Medicaid still covers the visit. The standard is whether a reasonable person would have thought it was an emergency, not whether it actually was.

Do I have to go to a specific hospital if I have Medicaid?

For emergencies, no. You can go to any hospital. If you are on a managed care plan, you may pay more if you go out of network, but the plan must cover emergency care at any hospital. For non-emergency care, your plan's network rules apply.

What if the emergency room bills me for something Medicaid should have covered?

Contact your state Medicaid office or your managed care plan and ask them to review the bill. If Medicaid should have covered it, the plan will pay the hospital, and you should not owe anything. Keep copies of all bills and your Medicaid card information so you can reference them.

Can I be charged for an emergency room visit if I do not have my Medicaid card with me?

No. Tell the hospital your name and date of birth, and they can look up your Medicaid coverage in the system. You do not need the physical card. However, bring your card if you have it, because it speeds up the process and ensures there are no mix-ups with your identity.

Does Medicaid cover emergency room visits for mental health crises?

Yes. If you are having a mental health emergency — suicidal thoughts, severe anxiety, psychosis — the emergency room is covered by Medicaid. The hospital will evaluate you and either treat you in the emergency room or admit you to a psychiatric unit. Medicaid covers both. Copays may apply depending on your state.
