What Medicare Pays for an Ambulance to the Emergency Room

Medicare covers ambulance transport to the emergency room, but only under specific conditions

Medicare Part B covers ground ambulance transport to a hospital or skilled nursing facility when a doctor determines that other transportation would endanger your health. The ambulance must be medically necessary — meaning your condition requires the equipment and personnel an ambulance provides, not just that you need a ride. If you call 911 and an ambulance arrives, Medicare will cover it if those conditions are met, regardless of whether you requested it.

The coverage applies to both emergency and non-emergency transports. An emergency call to 911 qualifies automatically if you are taken to a hospital. A non-emergency transport — say, from your home to the ER because your doctor says you cannot safely travel by car — also qualifies if your doctor documents that medical necessity in writing before the transport happens.

You pay 20 percent of the Medicare-approved amount after you meet your Part B deductible for the year. The ambulance company bills Medicare directly. If the ambulance company charges more than Medicare allows, you are not responsible for the difference — that is called balance billing protection, and it applies to ambulance services.

When Medicare will and will not pay

Medicare pays when a licensed ambulance company transports you by ground ambulance to a hospital, critical access hospital, or skilled nursing facility. The transport must be medically necessary — your condition must require the equipment, personnel, or monitoring that only an ambulance can provide. Examples include chest pain, severe difficulty breathing, loss of consciousness, or a fall with possible spinal injury.

Medicare does not pay for ambulance transport if you could safely travel by car, taxi, or another means. It also does not cover transport between two hospitals if you are stable enough to travel by wheelchair van or other non-ambulance vehicle. Air ambulances (helicopters) are covered only in rare cases — when ground transport would be too slow and delay would endanger your life, and only to the nearest appropriate facility. You must have a doctor's order for an air ambulance before it is called, or Medicare will deny the claim.

Private ambulance companies that are not Medicare-certified will not be covered. Always confirm that the ambulance company is Medicare-certified before transport if you have time to do so. In a true emergency, call 911; the ambulance that arrives will be certified.

How to make sure your transport is covered

For emergency 911 calls, do nothing in advance — just call 911. Medicare will cover the transport if you are taken to a hospital and the transport was medically necessary. The ambulance company will bill Medicare after you arrive.

For non-emergency transport, ask your doctor to write an order stating that ambulance transport is medically necessary before you arrange it. The order should explain why you cannot travel safely by car or other means. Give this order to the ambulance company before they arrive. The ambulance company will submit it to Medicare along with the bill. Without a doctor's order, Medicare will likely deny a non-emergency claim.

Keep any paperwork the ambulance company gives you — the receipt, the bill, or the Medicare Summary Notice (MSN) that arrives later. If Medicare denies the claim, you will need this paperwork to appeal. Check your MSN carefully: it will show what Medicare paid and what you owe.

What you will pay out of pocket

You pay 20 percent of the Medicare-approved amount for ambulance transport. The Medicare-approved amount varies by region and by ambulance company, but typically ranges from $400 to $1,200 for a ground ambulance transport. Your 20 percent share would be $80 to $240, depending on the approved amount in your area.

You must also have met your Part B deductible for the year. If you have not met it yet, you pay the full deductible first, then 20 percent of the approved amount after that. If you have a Medigap or Medicare Advantage plan, it may cover some or all of your 20 percent share — check your plan documents or call your plan to confirm.

The ambulance company cannot charge you more than the Medicare-approved amount. If they bill you for the difference between their charge and what Medicare allows, that is balance billing, and you can report it to Medicare. Call 1-800-MEDICARE to report balance billing.

Ambulance services Medicare does not cover

Medicare does not cover transport by private car, taxi, rideshare, or wheelchair van, even if ordered by a doctor. It does not cover transport between your home and a doctor's office or outpatient clinic — only transport to a hospital or skilled nursing facility. It does not cover transport for routine dialysis, physical therapy, or other scheduled outpatient services, even if you cannot drive yourself.

Air ambulances are rarely covered. Medicare pays for air transport only when ground transport would delay care so much that your life would be at risk, and only to the nearest appropriate facility. You must have a doctor's order before the air ambulance is called. If you call an air ambulance without a doctor's order, you will likely receive a large bill.

Specialty ambulances — such as bariatric ambulances for patients over a certain weight, or ambulances with advanced life support equipment — are covered under the same rules as standard ground ambulances, but the approved amount may be higher. Ask the ambulance company what the Medicare-approved amount is before transport if possible.

What to do if Medicare denies your ambulance claim

If you receive a Medicare Summary Notice showing that your ambulance claim was denied, read the reason code carefully. Common reasons for denial include: the ambulance company was not Medicare-certified, the transport was not medically necessary, or the transport was to a facility Medicare does not cover (such as a doctor's office).

You have the right to appeal. You must appeal within 120 days of the date on your MSN. Write to the address shown on your MSN and include a copy of your MSN, the ambulance bill, and any doctor's order or medical records that show the transport was medically necessary. Explain why you believe Medicare should pay. Send it by mail or upload it to your Medicare account at Medicare.gov.

If your appeal is denied, you can request a hearing before a Medicare contractor. This process takes longer but gives you a chance to present your case in more detail. Call 1-800-MEDICARE if you need help filing an appeal or if you are unsure whether your claim was denied.

Frequently Asked Questions

Will Medicare pay if I call 911 but refuse to go to the hospital?

No. Medicare covers the ambulance only if you are transported to a hospital or skilled nursing facility. If the ambulance arrives and you refuse transport, Medicare will not pay for the ambulance service. The ambulance company may bill you directly.

Does Medicare cover ambulance transport between two hospitals?

Only if the transport is medically necessary — meaning you are too unstable to travel by wheelchair van or other non-ambulance vehicle. If you are stable, Medicare will not pay for ambulance transport between hospitals. Ask the sending hospital whether the transport qualifies before you are moved.

What if the ambulance company says Medicare will not pay?

Ask the ambulance company to submit the claim to Medicare anyway. Do not pay the bill upfront. Let Medicare make the decision. If Medicare denies it, you can appeal. If you pay before the appeal is decided, you may not be able to recover the money.

Does my Medigap plan cover the 20 percent I owe for ambulance transport?

Most Medigap plans cover some or all of your 20 percent share for ambulance services. Check your plan documents or call your Medigap insurer to confirm what your plan covers. Medicare Advantage plans vary — call your plan to ask.

Can I use a private ambulance company instead of 911?

Yes, but only if the company is Medicare-certified. In an emergency, call 911 — the ambulance that arrives will be certified. For non-emergency transport, ask your doctor to order a Medicare-certified ambulance company and provide a written order stating medical necessity.
