Emergency Room Facility Fees: Why the Hospital and the Doctor Bill Separately

An emergency room (ER) visit usually produces at least two kinds of bills: one from the hospital for the facility (the room, nurses, equipment, and hospital services) and one or more from the doctors who treated you. With Original Medicare, Medicare.gov says you pay a copayment for each emergency department visit and a copayment for each hospital service you get, plus 20% of the Medicare-approved amount for your doctors' services after the Part B deductible ($283 in 2026). If you're admitted to the same hospital for a related condition within 3 days, you don't pay the ER copayments.

What is a facility fee?

A facility fee is what the hospital charges for the use of its emergency department. It's separate from what the doctor charges for their time and expertise. The hospital bill may also list tests, imaging, drugs, and supplies.

Doctors who work in the emergency room often bill on their own, even if they work inside the hospital. You may also get bills from a radiologist who read your X-ray or a lab that ran your blood work.

What does Medicare pay for an ER visit?

Medicare Part B covers emergency department services when you have an injury, a sudden illness, or an illness that quickly gets much worse. Medicare.gov says:

• You pay a copayment for each emergency department visit.
• You pay a copayment for each hospital service you get.
• After you meet the Part B deductible, you pay 20% of the Medicare-approved amount for your doctor's services.

If you have Medigap, it may pay some or all of these costs. Medicare Advantage plans set their own ER copayments.

When don't I pay the ER copayment?

Medicare.gov 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 copayments, because Medicare considers the visit part of your inpatient stay.

This only applies if you're formally admitted as an inpatient. If you stay under observation, you're still an outpatient, and the ER copayments and Part B costs apply.

Why did I get so many bills from one ER visit?

• The hospital facility bill covers the ER, nursing, and hospital services.
• The emergency physician's bill covers the doctor's care.
• Specialist bills may come from a radiologist, cardiologist, or other doctor who saw you or read your test.
• Ambulance bills come separately if you arrived by ambulance.
• Lab bills may come from an outside lab.

Each of these should appear on your Medicare Summary Notice (MSN).

How do I check ER bills?

1. Line up every bill with your MSN or your plan's Explanation of Benefits (EOB). Each provider should have a matching claim.
2. Check your status. Were you sent home, kept under observation, or admitted? If admitted within 3 days for a related condition, you shouldn't owe the ER copayment.
3. Compare to "maximum you may be billed." The bill shouldn't be higher than what your MSN shows.
4. Look for duplicates. The same test shouldn't appear on both the hospital and an outside lab bill.
5. Ask for an itemized bill if the hospital bill has a lump sum.
6. Check your Medigap payment. Your plan may cover the copayments and coinsurance.

Does the No Surprises Act apply to Medicare ER bills?

The No Surprises Act mainly protects people with private health insurance or no insurance. The Centers for Medicare & Medicaid Services (CMS) says people with Medicare already have protections against some unexpected out-of-network bills. With Original Medicare, the "maximum you may be billed" on your MSN is the key limit. Our article on the No Surprises Act covers this in more detail.

What should I say to the billing office?

"I'm calling about my ER visit on [date]. My Medicare Summary Notice shows a maximum I may be billed of $[amount] for this claim, but your bill shows $[amount]. Can you explain the difference? Also, I was admitted on [date]. Shouldn't the ER copayment be waived?"

What if I can't afford the ER bill?

Ask the hospital for its financial assistance application. Nonprofit hospitals must have a written financial assistance policy. If you qualify for a Medicare Savings Program like Qualified Medicare Beneficiary (QMB), providers can't bill you for Medicare cost sharing on covered services. You can also ask for an interest-free payment plan once you've confirmed the bill is correct.
