The logic behind surprise billing protection was simple and widely agreed: a patient who cannot choose their provider should not be exposed to that provider's out-of-network rate. It applied to emergency rooms, to the anaesthetist a patient never met, to the pathologist who read a slide. It was one of the more genuinely popular pieces of health policy in years.
Ground ambulances were left out of it. Air ambulances were included. The service a patient is least able to select — often while unconscious — remains able to bill the balance.
Nobody is negotiating on the patient's behalf
The exclusion was not an oversight so much as an unresolved argument. Ground ambulance services are overwhelmingly local: municipal fire departments, county EMS, volunteer squads, and private operators under contract to a town. Their rates are set by local government or by contract rather than by a national market, and a large share operate outside insurer networks entirely because they have no commercial reason to join one.
An operator that is the only ambulance service in its area has nothing to gain from accepting a negotiated rate. It will be called regardless. That is precisely the market failure the protections were written for, and it is the one they do not reach.
The amounts are not trivial. A transport of a few miles routinely bills in the high hundreds or low thousands, insurers pay a portion determined by their own schedule, and the difference goes to the patient. Households absorbing that are frequently the same ones already meeting a deductible for the emergency that prompted the call.
There is a reason operators defend the arrangement, and it deserves stating fairly. Ambulance services are expensive to keep ready and are paid mostly for transports — a crew sitting available all night generates nothing until someone calls. Public reimbursement covers a fraction of the cost of readiness, so commercial rates carry the standby capacity for the whole community. Cap those rates without replacing the readiness funding and some services simply close, in the same places where the volunteer fire department is already struggling to field a crew.
The states that have acted have mostly gone the same route: set a rate floor tied to a local benchmark, prohibit balance billing above it, and accept that the floor is generous enough to keep services solvent. It costs insurers more per ride and removes the patient from the middle, which is the trade the federal rule made everywhere else.
Until that spreads, the practical position for a household is unattractive. The bill can be appealed, the itemisation can be requested, and the service will frequently negotiate — none of which is reasonable to expect of someone recovering from the event that caused the ride. It joins the growing category of costs that arrive after the fact and are not really priced at all, alongside prior authorisation that both sides automated without shortening the wait.
