Does Medicare cover emergency room visits?
Last reviewed October 29, 20264 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
Medicare covers emergency room visits anywhere in the U.S. You do not need approval first. But what you pay depends on what happens next: going home, staying for observation, or being admitted. Here is what each one costs, and the traps that can raise your bill.
What Medicare covers in the ER
Part B covers care in a hospital emergency department when you have:
- An injury
- A sudden illness
- An illness that quickly gets much worse
That includes the ER doctor, tests, X-rays, and supplies. An ambulance ride to the ER has its own rules. See air ambulance.
For a problem that is not an emergency, an urgent care center often costs less. See urgent care. If you think your life is in danger, call 911.
What you pay
You get two kinds of bills from an ER visit.
- The hospital: a copay for the visit, and a copay for each hospital service, like a test or an X-ray. The copay for any one service cannot be more than the $1,736 Part A deductible for 2026. But all your copays added up can be more than that.
- The doctor: once you meet the $283 Part B deductible for 2026, you pay 20% of the Medicare-approved amount.
Copays at a small rural hospital called a critical access hospital can be higher.
- If you have a Medigap plan: most plans pay your copays and your 20%. Plan N may charge up to $50 for an ER visit when you are not admitted.
- If you have Medicaid too: Medicaid may pay your share. Ask your state Medicaid office.
Admitted or observation: the trap that changes your bill
What happens after the ER changes who pays.
- You are admitted. If your doctor writes an order to admit you to the same hospital for a related problem within 3 days of the ER visit, you do not pay the ER copays. Part A covers the visit as part of your hospital stay. You pay the Part A deductible instead.
- You stay for observation. Observation means the hospital is watching you while your doctor decides whether to admit you. You are still an outpatient, even if you sleep in a hospital bed overnight. You keep paying Part B copays for each service.
If you are in observation for more than 24 hours, the hospital must give you a form called a Medicare Outpatient Observation Notice. Each day you stay, ask: "Am I an inpatient or an outpatient?"
One more surprise: pills the hospital gives you while you are an outpatient, like pills you take every day at home, are usually not covered by Part B. Your Part D plan may pay you back if you file a claim.
In short: a night in the hospital is not the same as being admitted. Ask about your status.
If you have Medicare Advantage
Federal rules protect you in an emergency:
- Your plan must cover ER care in or out of its network, anywhere in the U.S.
- Your plan cannot require approval first for emergency care.
- Your plan must pay if a reasonable person would think it was an emergency, even if the final diagnosis turns out to be minor. Severe pain can count.
- For 2026, the ER copay cannot be more than $115, $130, or $150 a visit, based on your plan's yearly out-of-pocket limit. If the plan's normal copay is lower, you pay the lower amount.
Check your plan's Evidence of Coverage for your exact ER copay.
If you travel outside the U.S.
Original Medicare usually does not pay for ER care in another country. There are rare exceptions, like when a hospital in another country is closer than the nearest U.S. hospital that can treat you.
Some Medigap plans pay 80% of emergency care abroad, up to plan limits. Check your coverage before you travel.
In short: Medicare covers ER care in the U.S. Outside the U.S., you may need a Medigap plan or travel coverage.
Common questions about Medicare
Quick answers, fast .
Tap any question to expand. Each links to a fuller standalone answer.
Do I need approval before going to the ER with Medicare?
No. Original Medicare never needs approval first for the ER. Medicare Advantage plans cannot require it for emergency care either, even at an out-of-network hospital.
What if the ER visit turns out not to be an emergency?
Original Medicare covers ER care for an injury, a sudden illness, or an illness that quickly gets much worse. A Medicare Advantage plan must pay if a reasonable person would have thought it was an emergency, no matter the final diagnosis.
Why did I get two bills from the ER?
The hospital bills a copay for its services. The ER doctor bills separately, and you pay 20% of the Medicare-approved amount for the doctor after the Part B deductible.
Does Medicare cover the ER if I am kept overnight?
Yes, but you may still be an outpatient under observation. Then Part B copays keep adding up. Only a doctor's order to admit you makes you an inpatient under Part A.
