Why did I get a big bill for an ambulance ride? Doesn't Medicare cover it?

Question

Accepted Answer

Medicare Part B does cover ambulance rides — but only under specific conditions, and that is where most surprise ambulance bills come from.

Why you may have gotten a bill:
- Medicare only pays when the ride is considered medically necessary — meaning traveling any other way (car, taxi, wheelchair van) could have endangered your health. A situation that felt like an emergency to you may not meet Medicare's definition.
- The ambulance must take you to the nearest facility that can treat you. If it went farther (for example, to a hospital you prefer), Medicare may pay only part of the trip — or none of it.
- Non-emergency rides (a scheduled trip to dialysis, or a ride home after a hospital stay) usually need paperwork from a doctor confirming you could not travel any other way. Without it, the claim is denied.
- If the ambulance company has not agreed to Medicare's payment terms, you can be billed for more than the Medicare-approved amount.

What you can do:
1. Call the ambulance company's billing office. Ask whether the claim was sent to Medicare and exactly why it was denied or only partly paid — sometimes it is a paperwork or coding mistake they can fix and resubmit.
2. Look at your Medicare Summary Notice (the statement Medicare mails you). It shows the official denial reason and the deadline to appeal. If Medicare decided the ride was not medically necessary, you have the right to appeal.
3. If you also have Medicaid or other insurance, the bill may need to go to that plan next — ask the billing office whether it was sent.

Whether your bill can be lowered, resubmitted, or appealed depends on the exact denial reason on your notice — that is the kind of case we review. Describe your situation and we will walk you through the right next step.
