Does Medicare Cover Emergency Room Visits? 2026 Costs Explained
Reviewed September 29, 2026. Yes. Medicare Part B covers emergency room (emergency department) visits when you have an injury, a sudden illness or an illness that quickly gets much worse. With Original Medicare you pay a copayment for the visit and for each hospital service, plus 20% of the Medicare-approved amount for doctors’ services after the Part B deductible ($283 in 2026).
Quick answer: If the same hospital admits you as an inpatient for a related condition within 3 days of your ER visit, you don’t pay the ER copayments, because Medicare treats the visit as part of your inpatient stay. Part A’s inpatient deductible ($1,736 per benefit period in 2026) applies instead.
What Medicare covers in the emergency room
Medicare describes covered emergency department services as those you get in a hospital emergency department when you have an injury, a sudden illness, or an illness that quickly gets much worse. See Medicare’s emergency department services page. That typically includes:
- The emergency physician’s evaluation and treatment
- Hospital outpatient services during the visit, such as lab tests and imaging
- Drugs given to you as part of treatment in the ER
- Observation services if the hospital keeps you to decide whether to admit you
What you pay for an ER visit with Original Medicare
| Cost | 2026 amount |
|---|---|
| Part B deductible | $283 per year |
| Doctors’ services in the ER | 20% of the Medicare-approved amount after the deductible |
| Hospital facility charges | A copayment for the visit and a copayment for each hospital service |
| Part A inpatient deductible (if admitted) | $1,736 per benefit period |
Sources: Medicare.gov emergency department services and Medicare.gov 2026 Medicare costs. The exact copayment depends on the services you receive, so Medicare doesn’t publish a single flat ER price.
If you’re admitted within 3 days
Medicare says that 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 ER copayments because the visit is considered part of your inpatient stay. Read the rule on Medicare.gov.
Observation status: inpatient or outpatient?
Being kept overnight doesn’t make you an inpatient. Medicare says you’re an outpatient, even if you spend the night, when you’re getting observation services without a formal inpatient admission order. The hospital must give you a Medicare Outpatient Observation Notice (MOON) if you receive observation services for more than 24 hours. Because your status affects what you pay, Medicare suggests asking the hospital or your doctor each day whether you’re an inpatient or an outpatient. See Medicare’s guide to hospital status.
Ambulance rides to the ER
Part B covers ground ambulance transportation when traveling in any other vehicle could endanger your health, and only to the nearest appropriate medical facility. After the Part B deductible, you pay 20% of the Medicare-approved amount. See Medicare’s ambulance services page. Our guide to Medicare transportation services covers non-emergency rides.
ER coverage with Medicare Advantage
Medicare Advantage plans must cover emergency care, and HMO members can get emergency care outside the plan’s network. Medicare lists emergency care, out-of-area urgent care and temporary out-of-area dialysis as the exceptions to HMO network rules. Read Medicare’s HMO plan rules.
Each Medicare Advantage plan sets its own ER copayment and has a yearly out-of-pocket maximum. Check the “emergency care” line in your plan’s Summary of Benefits, and compare it during the fall Open Enrollment Period using our annual Medicare plan review checklist.
How Medigap helps with ER costs
A Medicare Supplement (Medigap) policy can pay some or all of the Part B coinsurance and the Part A deductible, depending on the plan letter. Medigap Plan N has its own rule: you pay a copayment of up to $50 for emergency room visits when you aren’t admitted as an inpatient. Compare Medigap plan benefits on Medicare.gov. See our breakdown of the difference between Medigap Plan G and Plan N.
Emergencies while traveling outside the U.S.
Medicare says it only covers emergency services outside the U.S. in rare situations. Many Medigap plans include a foreign travel emergency benefit that pays 80% of covered costs up to the plan’s limits, and some Medicare Advantage plans offer worldwide emergency coverage. Check your policy before you travel.
What Medicare may not pay for after an ER visit
Medicare pays for services that are medically necessary and covered. A few situations commonly lead to unexpected costs:
- Outpatient drugs you take home: Prescriptions filled after you leave the hospital fall under your Part D plan, not Part B.
- Self-administered drugs during observation: Medicare Part B generally doesn’t pay for self-administered drugs you get as a hospital outpatient; your Part D plan may help, so keep the receipts.
- Care outside the U.S.: Covered only in rare situations under Original Medicare.
- Providers that don’t accept assignment: They can charge more than the Medicare-approved amount, within limits.
After an ER visit: checking your bills
- Wait for your Medicare Summary Notice (Original Medicare) or Explanation of Benefits (Medicare Advantage) before paying a hospital bill in full.
- Compare the dates, services and amounts with the bills you receive from the hospital and doctors.
- Confirm whether you were an inpatient or an outpatient receiving observation services, since that changes which part of Medicare paid.
- If something looks wrong, call the provider’s billing office first, then Medicare or your plan.
- If Medicare denied a service you believe should be covered, you have the right to appeal.
ER or urgent care?
For a life-threatening emergency, call 911 or go to the nearest emergency room. For a sudden illness or injury that isn’t an emergency, an urgent care center is often less expensive. See Does Medicare Cover Urgent Care? for how those costs compare, and The Basics of Medicare Coverage for an overview of Parts A and B.
