Medicare covers ambulance service, but only when medically necessary and only to certain destinations

Medicare Part B covers ground ambulance transport when a doctor determines you need it for a medical reason — not for convenience or preference. The ambulance must take you to a hospital, skilled nursing facility, dialysis center, or your home (if you're returning from one of those places). If you call an ambulance and Medicare later decides it wasn't medically necessary, you may receive a bill for the full cost.

Air ambulances (helicopter or fixed-wing plane) are covered only in emergencies when ground transport would endanger your life or delay critical care. These are rare and expensive, and the rules are stricter than for ground ambulances.

Key Takeaways

  • Medicare Part B covers ground ambulance transport when a doctor says it's medically necessary, and you pay 20 percent of the approved amount after you meet your Part B deductible.
  • The ambulance must take you to a hospital, skilled nursing facility, dialysis center, or your home — not to a doctor's office, urgent care, or another location.
  • Air ambulances are covered only in life-threatening emergencies when ground transport would delay critical care, and you still pay 20 percent coinsurance.
  • If you call 911 and the ambulance arrives but you refuse transport, or if Medicare determines the trip wasn't medically necessary, you may owe the full bill.
  • Private ambulance companies and non-emergency medical transport services are not covered by Medicare, even if a doctor recommends them.

When Medicare pays for ground ambulance service

A ground ambulance is covered when all three of these are true: a doctor (or in an emergency, a paramedic) determines you need it for a medical reason; you cannot safely use another form of transport; and the ambulance takes you to a covered destination. "Medically necessary" means the trip is needed to treat an illness or injury, not straightforward to move you from one place to another.

The covered destinations are a hospital, a skilled nursing facility (where you're admitted for rehabilitation after a hospital stay), a dialysis center for kidney treatment, or your home if you're returning from one of those places. Transport to a doctor's office, urgent care clinic, outpatient surgery center, or another person's home is not covered, even if your doctor recommends it.

In an emergency, you do not need a doctor's order beforehand. If you call 911 and paramedics determine you need ambulance transport, Medicare will cover it if the destination is one of the covered locations. However, if you later refuse transport after the ambulance arrives, or if you ask to be taken somewhere not on the covered list, you become responsible for the cost.

What you pay for ground ambulance transport

If Medicare covers your ambulance trip, you pay 20 percent of the Medicare-approved amount after you have met your Part B deductible for the year. The ambulance company bills Medicare first, and Medicare sends you a bill for your share. The amount varies by region and by the type of transport (basic life support versus advanced life support), so your 20 percent will differ depending on where you live and what level of care you received.

If Medicare denies the claim because it decides the trip was not medically necessary, you may receive a bill from the ambulance company for the full cost. You have the right to appeal a denial. The ambulance company or your doctor can file an appeal on your behalf, or you can contact Medicare directly at 1-800-MEDICARE to ask about the decision.

Air ambulance coverage and limits

Air ambulance service — by helicopter or fixed-wing aircraft — is covered only in emergencies when ground transport would endanger your life or cause a dangerous delay in critical care. Examples include transport from a remote location where no ground ambulance can reach you quickly, or from an accident scene to a trauma center when minutes matter. The decision to use an air ambulance is made by medical personnel at the scene or by the receiving hospital, not by you or your doctor in advance.

You pay 20 percent coinsurance for air ambulance service after your Part B deductible, just as you do for ground transport. However, air ambulances are expensive — the approved amount can be several thousand dollars — so your 20 percent share may be substantial. Some supplemental insurance policies (Medigap) cover some or all of this coinsurance, so check your policy if you have one.

What Medicare does not cover

Private ambulance companies that operate as non-emergency medical transport services are not covered by Medicare. These are often used to move people between home and dialysis, or to transport people who cannot ride in a regular car but do not need emergency care. Even if your doctor recommends this service, Medicare will not pay for it. You would need to pay out of pocket or check whether Medicaid (if you may have access to) or your supplemental insurance covers it.

Wheelchair vans, medical transport vans, and other specialized vehicles are also not covered. Some area agencies on aging or local transit systems offer reduced-cost medical transport, so ask your doctor's office or call your local senior center for alternatives in your area.

How to make sure your ambulance trip is covered

In a true emergency, do not delay calling 911 to worry about coverage. Paramedics will transport you to the nearest appropriate hospital, and Medicare will cover it if the trip was medically necessary. The coverage question is settled after the fact, not before.

If you need non-emergency transport — for example, to a dialysis appointment or to a skilled nursing facility after discharge from the hospital — ask your doctor whether Medicare will cover an ambulance. Your doctor can write an order stating that ambulance transport is medically necessary, which strengthens the case if Medicare later questions it. If your doctor says an ambulance is not necessary, ask about alternatives: some hospitals and dialysis centers offer free or low-cost transport for patients, and some areas have volunteer ambulance services.

Keep copies of any paperwork the ambulance company gives you, including the bill and the reason for transport. If Medicare denies the claim, this documentation helps you appeal.

Frequently Asked Questions

If I call 911 and refuse to go to the hospital, do I have to pay for the ambulance?

Yes, you may be billed for the full cost if you refuse transport after the ambulance arrives. Medicare will not cover a trip you declined. If you are unsure whether you need to go, tell the paramedics and let them assess you — they can advise whether the trip is necessary.

Does Medicare cover an ambulance to my doctor's office?

No. Medicare covers ambulance transport only to a hospital, skilled nursing facility, dialysis center, or your home (if returning from one of those places). Transport to a doctor's office, urgent care, or outpatient clinic is not covered.

What if I have a Medigap policy — does it cover ambulance coinsurance?

Some Medigap plans cover part or all of the 20 percent coinsurance for ambulance service, but not all do. Check your policy documents or call your Medigap insurance company to find out what your plan includes.

Can I request an air ambulance if I think I need one?

No. Air ambulance use is decided by medical personnel based on the emergency and your condition, not by your request. If ground transport is safe and appropriate, that is what will be used, and Medicare will cover it.

What should I do if I receive a bill for an ambulance Medicare says it won't cover?

Contact Medicare at 1-800-MEDICARE to ask why the claim was denied. You can request an appeal, and your doctor or the ambulance company can help file it. Keep all paperwork related to the trip and the bill while the appeal is being reviewed.
