Original Medicare Part B covers emergency room visits, urgent care and medically needed ambulance rides. After the 2026 Part B deductible of $283, you usually pay 20% of the Medicare-approved amount. Hospitals may also charge a copayment for each outpatient service.
Key takeaways
- Part B (medical insurance) covers emergency room care, urgent care and emergency ambulance rides in the U.S.
- You usually pay 20% coinsurance after the 2026 Part B deductible of $283. On every $100 of the Medicare-approved amount, that is $20.
- If the same hospital admits you for a related problem, your emergency room visit usually becomes part of your inpatient stay under Part A.
- Medicare Advantage plans must cover emergency care in the U.S., in or out of network, without prior approval.
- Costs under private plans vary by plan, carrier and location, so check your plan's papers and your bills.
What does Part B pay in the emergency room?
- Part B deductible comes first$283 in 2026; set each year
- Hospital copayment for each outpatient serviceSuch as the visit, X-rays or lab tests
- 20% of the Medicare-approved amount for doctor servicesAbout $20 on every $100
- Copayment cap for a single hospital serviceUsually no more than the 2026 Part A deductible of $1,736
Emergency room care is an outpatient hospital service. Part B pays for it when you have an injury, a sudden illness or an illness that quickly gets worse.
You can get two kinds of charges. The hospital charges a copayment (a set amount you pay) for each hospital service, such as the visit, X-rays or lab tests. The doctors who treat you bill on their own.
For doctor services, you pay 20% of the Medicare-approved amount. That is the amount Medicare agrees to pay for a service. On every $100 of that amount, your share is $20.
The Part B deductible comes first. It is $283 in 2026 and is set again each year. Usually, the copayment for a single outpatient hospital service can't be more than the 2026 Part A hospital deductible of $1,736.
What if the hospital admits you?
| Admitted as inpatient | Under observation | |
|---|---|---|
| Which part pays | Part A | Part B |
| Emergency room visit | Usually part of the stay | Outpatient copayments apply |
| 2026 deductible | $1,736 per benefit period | $283 per year |
| Your share of doctor bills | 20% under Part B | 20% under Part B |
Sometimes the emergency room doctor admits you as an inpatient. If the same hospital admits you for a related problem, the emergency room visit usually counts as part of your inpatient stay. You don't pay a separate outpatient copayment for that visit.
Part A (hospital insurance) then covers the stay. In 2026, you pay the Part A deductible of $1,736 per benefit period (a stretch of care that starts when you are admitted). This amount is set each year.
Staying overnight does not always mean you are admitted. You may be under observation (you stay in the hospital but are still an outpatient). Then Part B pays, and you pay outpatient copayments and 20% coinsurance. Ask the staff which status you have. Our guide to hospital observation vs. admission explains why it matters.
Does Medicare cover urgent care visits?
Yes. Part B covers care at an urgent care center for problems that need quick care but are not emergencies. Examples are a sprain, a small cut, a fever or a bladder infection.
You pay 20% of the Medicare-approved amount after the Part B deductible. On every $100 of the approved amount, that is $20. If the center is part of a hospital, you may also owe a hospital copayment.
Urgent care can help when your own doctor's office is closed. For chest pain, trouble breathing or signs of a stroke, call 911 instead.
When does Medicare pay for an ambulance?
- You need emergency careSuch as a stroke, heart attack or serious injury
- Travel by car or taxi could endanger your health
- The ride goes to the nearest suitable facilityA hospital, critical access hospital or skilled nursing facility
- Air ambulance only when ground travel is too slow
- Non-emergency rides need a doctor's written order
Part B covers a ground ambulance when you need emergency care and travel by car or taxi could put your health in danger. The ride must go to the nearest hospital, critical access hospital or skilled nursing facility that can give the care you need.
Medicare may cover an air ambulance, by plane or helicopter, when ground travel can't get you to care fast enough. For any covered ambulance ride, you pay 20% of the Medicare-approved amount after the Part B deductible.
Non-emergency rides are covered only in limited cases. You may need a written order from your doctor saying an ambulance is medically needed, for example if you can't get out of bed. If the company thinks Medicare may not pay, it may give you an Advance Beneficiary Notice (a form saying you may owe the full cost). Read it before you sign.
How do Medicare Advantage plans handle emergencies?
A Medicare Advantage plan (Part C, a private plan you can choose instead of Original Medicare) must cover emergency and urgently needed care. The plan can't require prior approval for emergency care. You can go to any emergency room in the U.S., in or out of the plan's network.
Your costs are set by the plan. Copayments for emergency rooms, urgent care and ambulances vary by plan, carrier and location. Your plan's Evidence of Coverage (the yearly booklet that explains your plan) lists each amount. Inside your service area, the plan may ask you to use its own urgent care centers.
| Question | Original Medicare | Medicare Advantage |
|---|---|---|
| Who pays for the visit? | Part B, or Part A if admitted | The private plan |
| What you pay | Hospital copayment plus 20% | Plan copayment, varies by plan |
| Prior approval for emergencies | Not needed | Not allowed |
| Out-of-network emergency room | Any U.S. hospital that takes Medicare | Covered in the U.S. |
| Yearly spending limit | None | Plan limit for Part A and B services |
Both choices cover emergencies across the U.S. The main difference is who sets your share of the cost, and whether a yearly spending limit applies.
Can Medigap help with emergency costs?
Medigap (Medicare Supplement Insurance, a private policy that works with Original Medicare) can help pay the 20% Part B coinsurance and hospital copayments. How much it pays depends on the plan letter you choose. Some letters, such as Plan N, can leave you a copayment for some emergency room visits.
Plans C and F, which pay the Part B deductible, can't be sold to people new to Medicare on or after January 1, 2020. So if you are new, you pay the Part B deductible yourself. In 2026 it is $283, and it is set each year.
Medigap works only with Original Medicare, not with a Medicare Advantage plan. Policy prices vary by carrier and location.
What about emergencies outside the U.S.?
Original Medicare generally does not pay for care outside the U.S. There are a few narrow exceptions. One is an emergency in the U.S. when a foreign hospital is closer than the nearest U.S. hospital that can treat you.
Medicare Advantage plans generally do not cover care outside the U.S. either. Some Medigap plans include foreign travel emergency coverage, with limits. Learn more in Medicare away from home.
How can you check your emergency bills?
- Collect the hospital, doctor and ambulance bills
- Compare each bill with your Medicare Summary Notice
- Mark any service you did not get
- Report suspected fraud to 1-800-MEDICARE
After an emergency, you may get bills from the hospital, the doctors and the ambulance company. Compare each one with your Medicare Summary Notice (a statement listing the services billed to Original Medicare) before you pay it.
Look for services you did not get, and guard your Medicare Number. Report suspected fraud to 1-800-MEDICARE. Our guide to reading your Medicare Summary Notice shows how to spot errors and file an appeal.
If you have a Medicare Advantage plan, the plan sends you an Explanation of Benefits instead. For questions about your own coverage, Medicare.gov and 1-800-MEDICARE can help.
Have questions? Call 1-877-443-3251 to talk it through with a licensed insurance agent. You never pay the agent; the plans they represent do, and the decision stays yours.

What to do this week
- Write down the name and address of the nearest hospital emergency room and the nearest urgent care center, and keep the list by your phone.
- Find your red, white and blue Medicare card and any plan card, and put copies in your wallet and your emergency bag.
- If you have a Medicare Advantage plan, open your Evidence of Coverage and note the copayments it lists for the emergency room, urgent care and ambulance.
- If you have Original Medicare, check your latest Medicare Summary Notice to see how much of the 2026 Part B deductible of $283 you have already met.
- Make a list of your prescriptions, doctors and health conditions so you can hand it to emergency staff.
