What the No Surprises Act Covers, and Where Ground Ambulance Billing Falls Short<\/h2>\n\n\n\n
The No Surprises Act took effect on January 1, 2022, as part of the Consolidated Appropriations Act of 2021. It protects patients from balance billing in three situations: emergency care, certain non emergency care from out of network providers at in network facilities, and air ambulance transport. Ground ambulance billing was left out of that list. Air ambulance companies cannot balance bill patients for an out of network flight, but ground ambulance services can, because Congress chose to study the issue rather than regulate it outright when the law was written.<\/p>\n\n\n\n
That decision did not happen by accident. The law created the Advisory Committee on Ground Ambulance and Patient Billing, known as GAPB, and tasked it with reviewing how ground ambulance charges are disclosed, how consumers learn about their coverage, and how balance billing could be prevented. The committee met through 2023 and delivered formal recommendations to federal regulators in August 2024. Congress has not acted on those recommendations since, so ground ambulance billing protection at the federal level is still an open question.<\/p>\n\n\n\n
What Ground Ambulance Providers Are Still Required to Do<\/h2>\n\n\n\n
Even though the No Surprises Act does not ban balance billing for ground ambulance billing the way it does for air ambulances, providers are not free of obligations. Ground ambulance services, like other providers, must give good faith estimates of expected charges to uninsured or self pay patients who ask for one. Submit accurate claims and documentation, comply with state ambulance billing laws, provide price and billing transparency when required. They are also subject to notice and consent rules if a patient is asked to waive other surprise billing protections connected to hospital care. On the Medicare side, documentation matters enormously. Insufficient documentation alone accounted for nearly two thirds of improper ambulance payments in the most recent reporting period, ahead of medical necessity errors and coding mistakes. A clean claim depends on a physician certification statement and medical record documentation that clearly support why ground transport, and the level of service billed, was medically necessary.<\/p>\n\n\n\n
How States Are Filling the Ground Ambulance Billing Gap<\/h2>\n\n\n\n
Because the federal government has not closed this gap, states have stepped in on their own. As of early 2026, twenty two states have some form of protection against ground ambulance billing surprises for people with state regulated health plans. Some states cap what an out of network ambulance can charge at a percentage of the Medicare ambulance fee schedule. Others give insurers authority to set a reasonable payment, similar to the approach New York pioneered back in 2015. According to a recent Commonwealth Fund analysis<\/a>, more than one in four privately insured ground ambulance trips can still result in a surprise bill, and states without their own laws leave that gap wide open. State laws generally cannot reach self funded employer plans, which cover most American workers, so even a strong state law does not protect everyone.<\/p>\n\n\n\n For EMS agencies and the billing companies that support them, this patchwork is more than an academic problem. A claim that is fully compliant in one state can break billing rules in a neighboring one. Getting good faith estimates right, tracking which state laws apply to which payer, and keeping documentation tight for medical necessity all take coordination between clinical and billing staff. This is the kind of operational detail that platforms like expEDIum<\/a> are built to handle, since the software is already used by EMS and ambulance billing agencies that need claims to follow payer specific and state specific rules without slowing down reimbursement.<\/p>\n\n\n\n A few habits go a long way. Confirm whether the state where the transport occurred has its own ground ambulance billing protections, since rules vary on rate caps, public versus private providers, and which plans are covered. Make sure good faith estimate processes are in place for self pay patients, since this is a clear federal requirement regardless of state law. Tighten documentation at the point of care so medical necessity is obvious in the chart, not just on the claim. Keep an eye on Congress too, since the GAPB recommendations are sitting with federal regulators and any future action could change ground ambulance billing requirements nationwide with little notice. Billing software<\/a> that updates quickly, such as expEDIum’s RCM tools, helps agencies adjust without scrambling when rules shift.<\/p>\n\n\n\n Does the No Surprises Act protect patients from ground ambulance bills?<\/strong> Not directly. The law bans balance billing for air ambulance services and several other situations, but ground ambulance billing was excluded and left for further study.<\/p>\n\n\n\n Are ground ambulance providers required to give cost estimates?<\/strong> Yes. Like other providers, they must give good faith estimates to uninsured or self pay patients who ask for one, regardless of what state they operate in.<\/p>\n\n\n\n Do any federal rules still apply to ground ambulance billing?<\/strong> Balance billing itself is not restricted federally, but Medicare and Medicaid rules around documentation, medical necessity, and physician certification still apply and are strictly enforced.<\/p>\n\n\n\n Will Congress eventually regulate ground ambulance billing nationally?<\/strong> It might. The GAPB committee already delivered recommendations in 2024, but lawmakers have not acted on them, so for now states remain the main source of consumer protection.<\/p>\n\n\n\n Ground ambulance billing remains one of the more confusing corners of healthcare reimbursement, mostly because federal law stopped short of finishing the job. Until Congress picks the GAPB recommendations back up, providers, EMS agencies, and the billing partners they rely on, including expEDIum, will keep working through a state by state patchwork while still meeting the federal rules that do apply. Staying current on both fronts is the best way to bill correctly and keep patients from getting an unwelcome surprise after the worst day of their week.<\/p>\n\n\n\nWhat This Means for Providers and Billing Teams<\/h2>\n\n\n\n
