Does Medicare Cover the Emergency Room? (2026)

Yes, Medicare Part B covers emergency room visits when you have an injury, a sudden illness, or an illness that quickly gets much worse. What surprises people is how the cost is built: a copay for the visit, a copay for each hospital service, and 20% of the Medicare-approved amount for the doctor. This guide explains what you pay, the rule that can erase the copay, and how it works if you have Medicare Advantage or arrive by ambulance.1

What Medicare covers in the emergency room

Medicare Part B covers emergency department services, meaning the care you get in a hospital emergency room when you have an injury, a sudden illness, or an illness that quickly gets much worse.1

One important limit: Medicare usually does not cover health care while you are traveling outside the U.S., but there are real exceptions. For example, Medicare may pay if you are in the U.S. when an emergency happens and a foreign hospital is closer than the nearest U.S. hospital that can treat you, and Part B may pay for medically necessary care from a ship's doctor while the cruise ship is in a U.S. port or no more than 6 hours away from one. Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands and American Samoa all count as part of the U.S. If you travel internationally, our guide on Medicare coverage when you travel abroad explains when each exception applies.1

About these numbers: The 2026 figures below come from CMS and Medicare.gov, effective January 1 through December 31, 2026. Medicare costs change every year. For your exact copay or the current figures, ask the hospital what a visit and any tests will cost, or contact Medicare directly.

How much a Medicare emergency room visit costs

Emergency room billing has more moving parts than a typical doctor visit, so it helps to see them separately:1

• A copayment for the ER visit itself.
• A copayment for each hospital service you receive during the visit, such as tests or treatments.
• 20% of the Medicare-approved amount for your doctor's services, after you meet the Part B deductible ($283 in 2026).2

Because several copayments can stack up in a single visit, an ER trip can cost more than people expect. The amounts can vary, so it helps to ask what a visit and any tests or services will cost. A Medigap policy or other supplemental coverage may help cover those copayments and coinsurance.

The 3-day rule that can erase your ER copay

Here is the part worth knowing in advance. If your doctor admits you to the same hospital for a related condition within 3 days of your emergency room visit, you do not pay the emergency room copayment(s). Medicare then treats the ER visit as part of your inpatient stay, which is covered under Part A rather than billed as a separate outpatient ER visit.1

That shift is not automatically cheaper, because Part A has its own hospital deductible: $1,736 per benefit period in 2026. So the ER copay disappears, but if you are admitted you instead face that inpatient deductible (once per benefit period, not once per day). Whether you are formally admitted as an inpatient or kept in the hospital under observation can change what you owe, which is why the inpatient-versus-observation status distinction is worth understanding if you end up staying at the hospital.2

Does Medicare Advantage cover the emergency room?

If you have a Medicare Advantage (Part C) plan instead of Original Medicare, your emergency care is still covered. Every Medicare Advantage plan must cover all the medically necessary Part A and Part B services Original Medicare covers. (A few things stay with Original Medicare rather than the plan, including hospice care, some clinical-trial costs, and benefits that come from laws or Medicare policy decisions.) What changes is the cost structure: instead of Original Medicare's copay-plus-coinsurance math, your plan sets its own ER copay.3

Network rules do not block emergency care. Even an HMO, the plan type that otherwise generally requires you to get care from providers in the plan's network, covers emergency care outside that network, along with out-of-area urgent care and temporary out-of-area dialysis. A PPO also lets you use out-of-network providers for covered services, as long as they participate in Medicare or accept assignment, usually at a higher cost, and you are always covered for emergency and urgent care.4

The trade-off is that every Medicare Advantage plan has an annual cap on what you pay out of pocket for Part A and Part B services, federally limited to $9,250 for in-network care in 2026, and many plans set it lower. Original Medicare has no such cap, which is one reason some people carry Medigap alongside it. Check your plan's Summary of Benefits for the exact ER copay.3

Is the ambulance ride covered?

The ambulance is billed separately from the ER visit. Medicare Part B covers ambulance services when the transport is medically necessary (meaning your condition is such that being moved any other way could endanger your health) and you are taken to an appropriate medical facility. After the Part B deductible ($283 in 2026), you pay 20% of the Medicare-approved amount for the ride.5

Two things catch people off guard: if you are taken to a hospital farther away than the nearest one that can care for you, you may owe the difference in cost; and non-emergency ambulance transport is covered only when your condition makes other ways of traveling unsafe, and Medicare may pay for it when a doctor's written order says the ride is medically necessary. Our full guide to Medicare ambulance coverage walks through both, and if the ride is by helicopter or airplane, our guide to Medicare air ambulance coverage covers that case.5

These are 2026 amounts; the ER copay itself can vary, so ask what a visit and any tests will cost.1,2,5
