Emergency? Does Medicare Cover Your ER Visit?

Your ER Bill: What Medicare Actually Pays

You\'re in the ER. You need care. The last thing you want to worry about is the bill. So, does Medicare cover it? Yes.

Original Medicare (Parts A and B) covers services deemed \"medically necessary.\" This means your doctor must confirm the visit was needed to diagnose or treat a condition. Your specific situation and your doctor\'s notes determine coverage.

The 80/20 Rule: Your Share of the Bill

When Medicare covers your ER visit, they pay 80% of the approved amount. You\'re on the hook for the remaining 20%. Plus, you\'ll pay your Part B deductible (which is $257 in 2026). Remember, Original Medicare has no out-of-pocket maximum. That 20% can quickly become a financial burden.

A Medicare Supplement (Medigap) plan can be your financial shield. It covers that 20% coinsurance, often eliminating most or all of your out-of-pocket costs. For example, Plan G, a popular choice, covers everything Medicare leaves behind except the Part B deductible.

Common Questions About ER Coverage

What about Medicare Advantage plans?

Medicare Advantage (Part C) plans must cover ER visits, just like Original Medicare. However, their cost-sharing rules can differ. Some plans offer extra benefits, but they often limit you to a specific provider network. You might also need prior authorization for certain services.

How do I know if my ER visit is covered?

The best way to be sure is to ask your Medicare-enrolled provider. They can check your specific situation. You can also call 1-800-MEDICARE (1-800-633-4227) or visit Medicare.gov for official coverage details.

What if Medicare denies my claim?

If Medicare denies your claim, you have the right to appeal. You\'ll get a Medicare Summary Notice (MSN) or Explanation of Benefits (EOB) explaining why. You have 120 days from that notice to file an appeal.
