Disputing an air ambulance bill

Last reviewed 2026-11-02 · Billing situations

Short answerAir ambulance services are covered by the federal No Surprises Act, unlike ground ambulances. If you have a private health plan and received a large bill from an out-of-network air ambulance, compare it with your EOB, ask for an itemized bill, and contact your insurer and the CMS No Surprises Help Desk.

Why do air ambulance bills get so large?

Air transport is expensive to operate, and the company that flies you may not have a contract with your insurer. In an emergency you generally do not get to choose the provider, so the first notice of the price can be the bill itself.

Unlike ground ambulances, air ambulance services are covered by the federal No Surprises Act. That means a large bill from an out-of-network air ambulance is not simply something you have to absorb. It is worth checking carefully before you pay.

Who is protected?

The No Surprises Act applies to people with most private health plans, including employer plans and marketplace plans. It does not apply to Medicare, Medicaid, TRICARE, VA or Indian Health Service coverage, which have their own rules.

The exact details of how the law handles air ambulance payments and what you can be charged are summarized at cms.gov/nosurprises. Read that page or call the help desk rather than relying on a number you saw elsewhere, because the rules and processes are specific and can be updated.

What should you gather before you call?

A short, organized file makes every call easier.

The air ambulance bill, including the billing company's name and contact information.
Your insurer's EOB for the transport, showing what was allowed, paid and listed as your responsibility.
The date of service, pickup point and destination.
Any records showing why the flight was needed, such as hospital notes you can request.
A log of every call, with date, name and what was said.

What should you do step by step?

First, do not ignore the bill and do not pay the full amount until you have compared it with the EOB. Ask the air ambulance company for an itemized bill and ask them in writing to hold the account while it is reviewed.

Second, call your insurer. Ask how the claim was processed, whether the provider was treated as out-of-network, and whether the claim was handled under the No Surprises Act. Ask for a reprocessing if the amount you were billed seems higher than your plan's normal cost sharing.

Where can you escalate?

If the problem continues, call the CMS No Surprises Help Desk at 1-800-985-3059 or visit cms.gov/nosurprises. Complaints about an insurer's handling of the claim can go to your state insurance department, and billing practice complaints about the provider may go to your state attorney general.

A written dispute helps too. Medical Bill Dispute Pro can build a formal letter from your answers that lists the charge, applicable regulations, and a 10-business-day response request. Review it before sending.

Frequently asked questions

Is an air ambulance covered by the No Surprises Act?

Yes. Air ambulance services are covered by the federal No Surprises Act, which is a difference from ground ambulance services. The law applies to people with most private health plans. Check cms.gov/nosurprises for how it handles billing and the steps to take if you receive a bill you believe is not allowed.

What if I have Medicare or Medicaid?

The No Surprises Act does not apply to Medicare, Medicaid, TRICARE, VA or Indian Health Service coverage. Those programs have their own rules. Review your Medicare Summary Notice if you have Medicare, or contact your state Medicaid agency, since Medicaid providers generally may not bill beyond the Medicaid payment and allowed copay.

Should I pay the air ambulance bill while I dispute it?

Many people wait until the bill has been compared with the EOB and the insurer has finished reprocessing. If you decide to pay anything, consider paying only an amount you agree is correct and ask in writing whether payment affects the dispute. Keep receipts and records of every conversation.

Can the air ambulance company send my bill to collections?

It can if the account stays unpaid, which is why you should respond in writing and ask for a hold during review. If a third-party collector contacts you, you have rights under the Fair Debt Collection Practices Act, including disputing the debt in writing within the notice period.

How do I find out whether my insurer processed the claim correctly?

Call the number on your insurance card, ask how the claim was coded and whether the air ambulance was treated as out-of-network, then ask for the answer in writing. Compare it with your EOB. If you disagree, use your plan's appeal process and the deadline printed on your denial notice or EOB.
