Does Medicare cover emergency room visits?

What does Medicare cover in the emergency room?

Medicare Part B usually covers emergency department services: the services you get in a hospital emergency department when you have an injury, a sudden illness, or an illness that quickly gets much worse. Part B's covered outpatient hospital services include emergency or observation services, which may include an overnight stay in the hospital.

In the emergency department you're a hospital outpatient, even if you spend the night in the hospital, unless your doctor writes an order to admit you as an inpatient. Your hospital status affects how much you pay for hospital services and may also affect whether Medicare covers care in a skilled nursing facility after your hospital stay.

What do I pay for an emergency room visit with Medicare?

You pay a copayment for each emergency department visit and a copayment for each hospital service you get. After you meet the Part B deductible ($283 in 2026), you also pay 20% of the Medicare-approved amount for your doctor's services.

In most cases, the copayment for a single outpatient hospital service can't be more than the Part A inpatient hospital deductible ($1,736 per benefit period in 2026), but your total copayments for all outpatient services may be more than that deductible. If you get hospital outpatient services in a critical access hospital, your copayment may be higher and may exceed the Part A deductible.

What happens if I'm admitted to the hospital from the emergency room?

If your doctor admits you to the same hospital for a related condition within 3 days of your emergency department visit, you don't pay the emergency department copayments, because Medicare considers the visit part of your inpatient stay. You're an outpatient until you're formally admitted with a doctor's order and an inpatient after that. For most hospitals, Part A covers your inpatient hospital stay and all related outpatient services provided during the 3 days before your admission date, and Part B covers your doctor services.

Time you spend in the emergency room or under observation before you're admitted doesn't count toward the 3-day qualifying inpatient hospital stay Medicare requires before Part A covers skilled nursing facility care, even if you're there overnight. See how Medicare covers observation stays.

Does Medicare Advantage cover emergency room visits?

Medicare Advantage plans must cover all medically necessary services that Original Medicare covers, and some offer extra benefits; rules and costs vary by plan. Plans may ask you to use doctors and hospitals in the plan's network for non-emergency care. In a Medicare Advantage HMO, for example, you generally must use the plan's network except for emergency care, out-of-area urgent care and temporary out-of-area dialysis.

Each Medicare Advantage plan sets its own deductibles and copayments, which can be different from Original Medicare's, so check with your plan about what you pay for an emergency room visit.

Does Medicare cover emergency room visits outside the U.S.?

Only in rare situations. Medicare may pay for inpatient hospital, doctor and ambulance services in a foreign country in rare cases, such as when you're in the U.S. when a medical emergency occurs and the foreign hospital is closer than the nearest U.S. hospital that can treat your condition. Medigap policies may cover emergency care when you travel outside the U.S., and some Medicare Advantage plans may offer an extra benefit that covers emergency and urgently needed services when traveling outside the U.S. See Does Medicare cover you outside the U.S.?.
