A client transported by helicopter after a serious crash can arrive at the hospital having already generated a $50,000 to $120,000 air ambulance bill. That bill will not be fully covered by most health insurance plans, and the air ambulance provider's demand against the settlement frequently lands as one of the largest lien items in the disbursement. Understanding why these bills are so hard to reduce, and where the leverage actually exists, saves plaintiff firms from disbursing settlements that leave clients with a net recovery below the ambulance bill.
Why State Lien Caps Often Don't Apply to Air Ambulance
Most states have hospital lien statutes that cap the amount a provider can recover from a PI settlement. California Health and Safety Code section 3045 is the model: it limits hospital liens to a percentage of the gross settlement or net recovery. Many practitioners assume these caps apply to all medical providers, including air ambulance companies. They do not.
The Airline Deregulation Act of 1978 (ADA), 49 U.S.C. § 41713, preempts any state law that relates to the price, route, or service of an air carrier. Air ambulance services operated under an FAA air carrier certificate qualify as air carriers under the statute. Federal courts, including the Ninth Circuit in Scarlett v. Air Methods Corp., have held that state laws attempting to regulate air ambulance pricing, including state lien-cap statutes, are preempted by the ADA. The practical result: the air ambulance company's billed amount is largely beyond the reach of state law, and the health insurer's negotiated rate, if any, governs only the insured portion of the bill.
The No Surprises Act: What It Covers and What It Doesn't
The federal No Surprises Act, effective January 1, 2022, imposed independent dispute resolution (IDR) procedures and patient protection requirements on certain out-of-network medical billing situations. It extended limited air ambulance billing protections through the Air Ambulance and Patient Billing dataset requirements and mandated disclosures. However, Congress did not include air ambulance in the full balance-billing protection provisions of the No Surprises Act, which apply to facility-based services and emergency ground transport services in limited circumstances.
As a result, uninsured PI clients and clients whose health plan does not cover air ambulance face the full billed charge with limited federal recourse. Insured clients may benefit from their plan's IDR dispute resolution process, but the settlement proceeds (and the plaintiff attorney handling disbursement) are not direct participants in the IDR process and cannot force resolution on a timeline that fits the settlement.
Negotiation Leverage in Air Ambulance Lien Resolution
Despite the preemption problem, negotiation is not pointless. Several leverage points exist:
- State insurance commissioner complaints: Where the air ambulance company is demanding payment from an insured's settlement despite a co-payment obligation that the insurer should cover, insurance commissioner complaints can accelerate resolution of the insurer-carrier dispute and reduce the amount that flows to the lien.
- Charity care and hardship waiver applications: Most air ambulance providers have statutory or contractual charity care obligations under the terms of their hospital or health system affiliations. A documented financial hardship application through the provider's billing department can result in reductions of 40 to 70 percent on the uninsured or underinsured balance.
- Common fund doctrine: Where the plaintiff's attorney's work generated the fund from which the ambulance lien is paid, a demand for pro-rata contribution to attorney fees and costs has succeeded in reducing air ambulance demands, though the preemption argument may limit the statute's reach on the amount itself.
- Medical billing audit: Air ambulance billing errors, upcoded base rates, and duplicate charges appear with enough frequency that retaining a medical billing auditor before paying any lien in excess of $20,000 is standard practice at sophisticated PI firms. An audit finding of even a 10 percent billing error on a $90,000 air transport bill produces a significant reduction.
Ground Ambulance: A Separate and Simpler Analysis
Ground ambulance billing does not trigger the Airline Deregulation Act preemption because ground transport is not an air carrier service. State hospital lien statutes, Medicaid rate schedules, and standard balance-billing protections apply to ground transport providers. Municipal ambulance services often operate under fee schedules set by local ordinance and may have separate lien-perfection requirements (such as timely filing against the specific recovery vehicle) that must be met before the lien is enforceable at all.
In California, a ground ambulance service operated by a hospital district must comply with the hospital lien perfection requirements of Health and Safety Code section 3045.1, including a written notice sent to the responsible party within 72 hours of transport. A lien based on an ambulance trip where the notice was untimely or misdirected is often defeatable entirely.
Disbursement Checklist for Cases With Air Transport
- Obtain a copy of the air transport provider's FAA certificate to confirm air carrier status and preemption exposure.
- Request an itemized bill and confirm the base rate, loaded mileage rate, and any add-on charges separately.
- Determine whether the client had health coverage that included any air ambulance benefit at the time of transport.
- File a charity care or hardship application before accepting any settlement that includes an air ambulance lien.
- If the insurer and the air ambulance company are in a rate dispute, resolve it before disbursing proceeds to avoid liability for disbursing over a contested lien.
