A Montgomery County, Pennsylvania mother's $4,576 ground ambulance bill exposes a critical gap in federal surprise-billing protections: the federal No Surprises Act, which took effect in January 2022 and shields consumers from unexpected medical charges, explicitly excluded ground ambulance services from coverage. This exclusion leaves millions of insured patients vulnerable to bills they cannot predict or control. The No Surprises Act protects emergency care and air ambulance services, but Congress deferred action on ground ambulances due to complications with how they are delivered—mostly through municipalities—and lack of cost data. That decision created a loophole that is now costing consumers thousands of dollars per transport.

Why Ground Ambulances Fall Through the Federal Gap
The No Surprises Act shields patients from out-of-network emergency care charges, but ground ambulance services are conspicuously absent. Congress acknowledged the gap when writing the law but chose to exclude ground transport entirely, leaving it to states to decide. In contrast, the law covers air ambulances by capping cost-sharing at in-network rates, creating an unequal protection for ground-based emergency transport.
The exclusion happened because Congress faced practical complications. Ground ambulances are delivered mostly by municipalities and local governments rather than private companies, which raised concerns about disrupting existing contracts and impacting public budgets. Congress deferred the decision and created an advisory committee instead, leaving the problem unresolved.
How Common Are Surprise Ambulance Bills?
The problem is widespread. More than one of four privately insured ground ambulance trips result in a surprise bill, with the average ground ambulance charge for commercial insurance at $1,093. For someone transported during a medical emergency, a four-figure bill arrives weeks later—after the crisis has passed and payment options are limited.
The financial impact compounds because patients have no control over the decision. Consumers cannot select an ambulance service when dialing 911, so they encounter the bill after the fact, with no negotiating power and no alternative to have chosen in the moment.
What State-Level Protections Exist?
As of 2026, 22 states have enacted ground ambulance balance-billing laws, filling the federal gap with their own rules. States are experimenting with different payment limits and enforcement approaches, creating a patchwork of protections that varies by geography. However, state protections have a critical limitation. These laws apply only to state-regulated health plans (fully insured plans), leaving approximately 60% of insured patients unprotected because employer-sponsored self-funded plans are exempt from state laws under federal ERISA rules.
This means large employers often self-insure their employee health plans, and those plans are not bound by state ambulance protections. A resident in a state with protections may still owe thousands if their employer self-funds their insurance.
What Can You Do if You Receive an Ambulance Bill?
Start by reviewing your insurance policy and state laws. If you live in a state with ground ambulance protections, verify that your plan is subject to those rules—self-funded employer plans are not. Check whether your insurance denies the claim outright or assigns you a cost-sharing obligation. If the bill appears to be a surprise charge—an out-of-network provider you could not have avoided—contact your insurance company and request an explanation.
Ask whether your state has balance-billing protections that apply to your plan. Keep documentation of the emergency transport, the billing date, and your insurance coverage at the time of service. If the bill violates your state's protections, file a complaint with your state insurance commissioner or attorney general's office.
Is Federal Action Likely?
The federal gap remains open because Congress has not revisited the issue since 2022. The advisory committee created to study ground ambulances has not produced binding protections, and legislative change would require Congress to balance consumer protection against concerns about municipal budgets and existing provider contracts. In the meantime, patients in states without protections remain fully exposed, and even those in protected states may find their self-funded employer plans exempt from coverage. The $4,576 bill from Pennsylvania illustrates a patient in a state that has not yet passed ground ambulance protections, but even if Pennsylvania had done so, a self-funded employer plan would not be bound by that law.
Frequently Asked Questions
Does my insurance cover surprise ground ambulance bills?
The federal No Surprises Act does not. If you live in one of 22 states with ground ambulance protections, coverage depends on whether your plan is fully insured or self-funded—employer self-funded plans are exempt from state protections.
Can I refuse an ambulance or choose which one to use?
No. Emergency dispatch sends the available unit, and you have no choice. This is why balance billing occurs after the fact, when you cannot negotiate.
What should I do if I receive an unexpected ambulance bill?
Contact your insurance company to request an explanation. Check your state's laws and whether your plan is subject to them. If the charge violates your state's protections, file a complaint with your state insurance commissioner.
