Surprise Medical Bills and Ambulances: What’s Still at Risk

Federal protections have dramatically reduced many surprise medical bills, but one critical gap remains: ground ambulance services are often still outside the law’s reach. For patients, that means a single 911 call can still lead to hundreds or even thousands of dollars in unexpected charges.

This article explains how today’s rules work, why ambulance rides are still risky, and what you can do to protect yourself and your family.

From Unchecked Surprise Billing to the No Surprises Act

Before 2022, patients could be treated at a hospital they believed was covered under their insurance, only to discover that some providers or services were out-of-network and billed them directly for large balances. These charges were commonly called surprise bills or balance bills.

To address this, Congress enacted the No Surprises Act, effective January 1, 2022, which created nationwide protections for many—but not all—situations where patients have little control over who treats them.

What Counts as a Surprise Medical Bill?

At its core, a surprise medical bill is an unexpected charge that arises when you receive care from an out-of-network provider or facility without realizing it or without a meaningful opportunity to choose someone in-network.

Under the No Surprises Act, many of these situations are now regulated so patients pay only their normal in-network cost-sharing and are protected from balance billing.

Core Protections Under the No Surprises Act

The No Surprises Act applies to most types of commercial health coverage and creates several key safeguards when you lack control over who provides care.

Emergency Services at Hospitals and Emergency Departments

• Most hospital emergency care is treated as in-network for billing purposes, even if the hospital or staff are outside your plan’s network.
• Plans must cover emergency services without prior authorization and at in-network cost-sharing levels.
• Providers generally cannot send you balance bills for emergency services.

These protections extend to emergency services needed to stabilize you and some care provided immediately before and after stabilization.

Out-of-Network Providers at In-Network Facilities

The law also protects you when you visit an in-network hospital or ambulatory surgical center but are unknowingly treated by out-of-network clinicians within that facility.

• Ancillary services like anesthesiology, radiology, pathology, neonatology, and certain hospital-based physicians cannot generally balance bill you.
• You pay only in-network cost-sharing; disputes over the remainder occur between the provider and your plan.

Air Ambulance Services

Emergency transport by air ambulance has historically produced extreme surprise bills due to high costs and frequent out-of-network status. The No Surprises Act specifically includes out-of-network air ambulance services:

• You are protected from balance billing by out-of-network air ambulance companies.
• Cost-sharing is limited to your in-network amounts.

Because air ambulances are covered by federal law, insurers and air ambulance providers use a separate dispute resolution process to settle payments, keeping patients out of the middle.

The Major Loophole: Ground Ambulance Billing

Despite these broad protections, one glaring exception remains: ground ambulances are not generally covered by the federal No Surprises Act. That means a ride in a local ambulance can still result in significant out-of-network charges and balance bills.

Research and policy analysis indicate that surprise bills are especially common for ground ambulance services, and average surprise bills can be several hundred dollars or more.[10] Patients often have no opportunity to compare prices or networks during an emergency call, yet remain exposed to charges when the ambulance provider is outside their health plan’s network.

Why Ground Ambulances Were Left Out

There are several reasons policymakers and analysts highlight for this gap:[10]

• Fragmented system: Ground ambulances may be operated by cities, counties, fire departments, hospital systems, or private companies, making one-size-fits-all federal rules complex to implement.[10]
• Local regulation: Many aspects of ambulance operations and rates are traditionally set at the state or local level, complicating national standards.
• Funding considerations: Some local governments rely on ambulance revenue to support emergency services, raising policy questions about how strict billing limits would be offset.

As a result, Congress chose to address ground ambulances separately, and states have begun filling the gap with their own protections.[10]

State-Level Efforts to Protect Ground Ambulance Patients

Because the federal law largely excludes ground ambulances, states have started to enact their own rules to reduce surprise billing for these services.[10]

Analyses of state laws show that more than twenty states have adopted some form of protection for consumers facing ground ambulance bills, with differing scope and strength.[10]

Examples of State Protections

• Texas has enacted laws that prohibit certain surprise bills from ground ambulance services for many insured patients, particularly when their insurance cards show state-regulated coverage like “DOI” or “TDI.”
• Several states ensure that out-of-network ambulance providers cannot bill patients more than in-network cost-sharing amounts and instead must negotiate directly with insurers.[10]
• Some states cover both emergency and non-emergency ground ambulance transport, while others focus solely on emergency rides.[10]

The details vary, so your protections depend heavily on where you live and the specific insurance coverage you have.

What Patients Still Need to Watch For

Even with federal and state reforms, patients can still encounter high or unexpected medical bills. It is important to understand what is not covered or limited by the No Surprises Act.

Common Remaining Risks

• Ground ambulances in many states and plans can still generate out-of-network bills and balance charges if not governed by state protections.[10]
• Services not covered by your plan, such as certain elective procedures or excluded benefits, may be billed in full, even if provided in-network.
• Intentionally out-of-network care: If you knowingly choose a provider outside your network, the bill is not considered a “surprise” under federal rules.
• Facilities outside the law’s scope, like some urgent care clinics or independent physician offices, may not be covered by the federal protections.

Indicators That an Ambulance Bill Could Be a Surprise Bill

Watch for these warning signs in ambulance-related invoices:

• The ambulance company is listed as out-of-network in your plan documents.
• You are billed separately by the ambulance provider for a large “balance” beyond what your insurer paid.
• The bill total is substantially higher than your normal emergency copay or coinsurance.
• Codes or descriptions suggest non-emergency transport that may not be fully covered.

Practical Steps to Reduce Ambulance Billing Risks

While emergencies rarely allow for careful shopping, there are practical measures you can take before and after

Before an Emergency: Know Your Coverage

• Review your plan documents for information on emergency services and ambulance coverage, including ground and air transport.
• Check if your state has specific protections for ground ambulances by visiting your state insurance department or attorney general’s consumer pages.
• Identify local emergency providers (hospitals and major ambulance services) and confirm their network status with your insurer, if possible.

During an Emergency: Prioritize Safety

In a medical emergency, your health and safety should always come first. It is rarely realistic or advisable to delay care to compare ambulance options. Nonetheless:

• If time and circumstances allow—such as for non-urgent transport—ask whether a particular ambulance service is in-network.
• When choosing between facilities, if medically reasonable, request transport to an in-network hospital to reduce subsequent surprise bills for hospital-based services.

After the Ambulance Ride: Manage the Bill

Once you receive an ambulance bill, there are concrete steps you can take to challenge or reduce unexpected charges.

• Compare the bill to your Explanation of Benefits (EOB) from your insurer to see what was covered and at what rate.
• Call your insurer to clarify whether the ambulance provider should have been treated as in-network under state or federal protections.
• Dispute incorrect charges by following your plan’s appeal process and, where applicable, using the federal or state dispute systems for surprise billing.
• Contact regulators such as your state insurance department or attorney general’s consumer health unit if you believe you were improperly balance billed.
• Ask the ambulance provider about financial assistance, discounts, or payment plans if you are unable to pay the full amount.

Your Rights When You Receive a Surprise Bill

Patients have formal rights and avenues to challenge certain surprise bills, including those potentially related to emergency transportation and post-emergency care.

• Under the No Surprises Act, if you receive a bill that appears to conflict with the protections—for emergency hospital care, air ambulances, or out-of-network providers at in-network facilities—you can file complaints through federal channels.
• Some state laws allow you to dispute bills that significantly exceed pre-treatment estimates or that appear to violate state surprise billing rules.
• Many states provide hotlines or online complaint forms via insurance departments or attorneys general for suspected surprise billing issues.

Keep all documentation, including bills, EOBs, and any written estimates. These records will be important if you pursue an appeal or regulatory complaint.

Frequently Asked Questions About Ambulance Surprise Bills

Are all ambulance rides considered emergency services under the law?

No. Some ambulance transports are classified as non-emergency, such as scheduled transfers between facilities. These may be subject to different coverage rules and may not qualify for emergency protections.[10] Check your plan documents and discuss the classification with your insurer if you receive a bill.

Does the No Surprises Act cover my ground ambulance if it took me to an emergency room?

Not necessarily. The federal law generally covers emergency hospital services and air ambulances, but does not broadly regulate ground ambulance billing. Your protection will depend on state law and the terms of your health plan.

If I sign a consent form, can I lose my surprise billing protections?

In certain non-emergency situations at in-network facilities, providers may ask you to sign a consent form to receive out-of-network care and waive federal protections against balance billing. You are not required to sign, and you should ask whether an in-network alternative is available before agreeing.

How can I find out whether my state protects me from ground ambulance surprise bills?

Consult official resources such as your state insurance department or attorney general’s office. Many publish clear consumer guidance on surprise billing and ambulance protections. Look for sections labeled “surprise medical bills,” “No Surprises Act,” or “ambulance billing.”

What should I do if I get a very high ambulance bill?

First, confirm the charges with your insurer and check whether the provider is in-network. Then:

• Ask if state or federal surprise billing protections apply to your situation.[10]
• File an appeal with your plan if you believe the claim was processed incorrectly.
• Contact your state regulators or the federal help line for surprise billing to explore dispute options.
• Negotiate with the ambulance provider for possible reductions or payment arrangements.
