Does Medicare cover emergency room visits?
Medicare Part B covers emergency room visits, with a copay for the visit plus 20% coinsurance for physician services after the Part B deductible.
What flips the answer
- Covered when
You have Medicare Advantage — visits are covered but at your plan's ER copay, usually waived if you're admitted.
- Not covered when
You're admitted as an inpatient for the same condition — the ER visit is billed under your Part A stay, not as a separate ER copay.
- Not covered when
The visit is outside the United States — Original Medicare generally won't cover it without a Medigap or Advantage plan that adds foreign travel coverage.
Emergency room visits are covered by Part B when you have a serious, sudden medical need. The benefit applies nationwide and doesn't require a referral.
You typically pay the Part B deductible, a copay for the hospital ER, and 20% coinsurance for the doctors who treat you. When the visit results in a hospital admission for the same condition, Medicare treats it as part of your Part A inpatient stay, and the inpatient deductible replaces the ER copay.
Medicare Advantage plans must also cover emergency room visits, in and out of network, but charge their own copayment. Original Medicare's ER coverage stops at the U.S. border, aside from a few narrow exceptions and certain supplemental plans.
