Medicare covers emergency room visits, but what you pay depends on which part of Medicare you have and whether the visit counts as an emergency under Medicare's rules
If you have Medicare Part B, it covers emergency room care at any hospital that accepts Medicare. You pay a copay — the fixed amount you owe per visit — which is currently $185 for an ER visit that does not result in hospital admission. If you are admitted to the hospital from the ER, you pay the hospital deductible instead (currently $1,556 per benefit period), and the copay does not explore.
The catch is that Medicare only pays if the ER visit is truly an emergency. Medicare defines an emergency as a medical condition severe enough that waiting for a scheduled appointment could seriously harm your health. A broken bone, chest pain, severe bleeding, difficulty breathing, or sudden loss of consciousness count. A routine check-up or a problem that could wait until your doctor's office opens does not, even if you go to the ER.
If Medicare decides your ER visit was not an emergency, you become responsible for the full bill. This happens rarely, but it does happen — usually when someone goes to the ER for something like a minor rash or a question that could have been answered by a nurse hotline. You have the right to appeal if you disagree with Medicare's decision.
Key Takeaways
- Medicare Part B covers ER visits that count as true emergencies, and you pay a $185 copay if you are not admitted to the hospital.
- If you are admitted to the hospital from the ER, you pay the hospital deductible ($1,556 per benefit period) instead of the ER copay.
- Medicare only pays if the condition is severe enough that waiting could harm your health; routine problems or non-urgent issues may not be covered.
- If Medicare denies the claim as non-emergency, you can appeal the decision and request a review.
- Costs are the same whether you go to an in-network or out-of-network hospital, as long as it accepts Medicare.
How the ER copay works with your deductible
The $185 copay applies only if you leave the ER without being admitted. This copay counts toward your Part B deductible if you have not met it yet that year. Your Part B deductible for 2024 is $240 — once you have paid $240 out of pocket for covered services, Medicare starts paying its share of most services.
If you are admitted to the hospital from the ER, the copay disappears and you pay the hospital deductible instead. The hospital deductible is separate from the Part B deductible and is higher ($1,556 for 2024). You pay this once per benefit period, which runs from October 1 to September 30 each year.
If you have already met your Part B deductible earlier in the year, the $185 ER copay is all you owe for a non-admission visit. If you have not met it, you pay the copay, and it counts toward the $240 you need to spend before Medicare's cost-sharing kicks in.
What happens if you go to an out-of-network ER
Medicare covers ER visits at any hospital that accepts Medicare, whether it is in your insurance network or not. You pay the same $185 copay at an out-of-network hospital as you would at an in-network one. This is one of the few areas where Medicare does not penalize you for going out-of-network, because in a true emergency you do not have time to check whether a hospital is in your plan.
The rule is different for urgent care centers and walk-in clinics. These are not hospitals, and Medicare coverage varies. Some urgent care centers accept Medicare and some do not. If you go to one that does not accept Medicare, you pay the full bill. Before you go, you can call ahead and ask whether they accept Medicare.
When Medicare might not pay for your ER visit
Medicare denies ER claims most often when the visit was not truly an emergency by Medicare's definition. Examples include going to the ER for a minor cut that could have been treated at home, a rash that has been present for weeks, or a question about medication that could have been answered by your doctor's office or a nurse hotline.
You also will not be covered if you go to a facility that does not accept Medicare at all. This is rare — most hospitals accept Medicare — but some specialty clinics or private urgent care centers do not. Always ask before you go if you are unsure.
If you receive a bill saying Medicare denied your ER visit, read the notice carefully. It will explain why Medicare did not pay. You have the right to request a review if you believe the decision was wrong. Contact Medicare at 1-800-MEDICARE to start an appeal.
How Medigap and Medicare Advantage plans affect your ER costs
If you have a Medigap policy (supplemental insurance), it may pay some or all of your $185 ER copay, depending on which Medigap plan you chose. Most Medigap plans cover the Part B copay. Check your policy documents or call your Medigap insurer to confirm what your plan covers.
If you have a Medicare Advantage plan instead of Original Medicare, your ER copay is set by your plan, not by Medicare. It could be $100, $250, or a different amount — it depends on your specific plan. Your plan documents will list the ER copay. Medicare Advantage plans must cover emergency room visits, but the cost to you varies.
Both Medigap and Medicare Advantage plans must cover true emergencies. The difference is in how much you pay out of pocket. If you are unsure what your plan covers, call the customer service number on your insurance card.
What to do before and after an ER visit
Bring your Medicare card to the ER. The hospital needs it to bill Medicare correctly. If you have a Medigap or Medicare Advantage card, bring that too. The ER staff will handle the billing — you do not need to do anything except provide your insurance information.
After you leave, you will receive an Explanation of Benefits (EOB) from Medicare showing what was billed and what Medicare paid. Review it to make sure the visit was coded as an emergency. If you see an error or if Medicare denied the claim, contact Medicare at 1-800-MEDICARE within 120 days to request a review.
If you receive a bill from the hospital after Medicare has paid, do not ignore it. Contact the hospital's billing department and ask them to explain the charge. If you believe you should not owe it, you can dispute it with Medicare.
Frequently Asked Questions
Do I have to call my doctor before going to the ER?
No. In a true emergency, you should go straight to the ER. Medicare does not require you to get permission from your doctor first. If you are unsure whether something is an emergency, you can call a nurse hotline or your doctor's office, but you do not have to wait for a response if you think you need when ready care.
Will Medicare pay if I go to the ER for something that turns out to be minor?
Yes, as long as the condition seemed serious enough to warrant emergency care at the time you went. Medicare does not deny claims based on the outcome — only on whether the condition was genuinely urgent when you arrived. A chest pain that turns out to be indigestion is still covered because chest pain is an emergency symptom.
What if the ER bills me for something Medicare should have paid?
Contact the hospital's billing department first and ask them to resubmit the claim to Medicare or explain why they are billing you. If they do not resolve it, call Medicare at 1-800-MEDICARE and file a complaint. You can also contact your state's insurance commissioner's office if the hospital refuses to work with you.
Does Medicare cover the ambulance ride to the ER?
Yes, Medicare Part B covers ambulance transport to the ER if it is medically necessary. You pay 20% of the approved amount after you meet your deductible. If you call 911, the ambulance is covered as long as you go to a hospital that accepts Medicare.
Can I be charged more than the copay if I go to an out-of-network ER?
No. Medicare sets the copay at $185 for all hospitals that accept Medicare, in-network or out-of-network. You cannot be balance-billed for the difference. The hospital must accept Medicare's payment plus your copay as payment in full for the ER visit.
