The Law That Changed Everything for Patients
Before January 1, 2022, getting a surprise medical bill was one of the most financially devastating things that could happen to an American family. You could do everything right — choose an in-network hospital, verify your insurance coverage, follow your doctor's referral — and still receive a bill for $10,000 or more from an out-of-network anesthesiologist or radiologist you never chose and never even met.
I worked with a family in Virginia whose daughter needed an emergency appendectomy. They went to their in-network hospital. The surgeon was in-network. But the anesthesiologist — whom they had no ability to choose or even know about beforehand — was out-of-network. The family received a separate bill for $8,400 from the anesthesia group. They had done nothing wrong. The system had failed them.
The No Surprises Act (NSA) was signed into law in December 2020 and took effect on January 1, 2022. It is the single most important piece of patient protection legislation in a generation, and yet most Americans still do not fully understand what it covers, what it does not cover, and how to use it when they receive a bill that violates it.
What Exactly Does the No Surprises Act Cover?
The NSA protects patients in three specific situations. Understanding these categories is critical because the law does not cover every surprise bill — only those that fall into these defined scenarios.
1. Emergency Services (Broadest Protection)
This is the strongest protection in the law. All emergency services are covered, regardless of whether the facility or any provider who treats you is in-network or out-of-network. This includes:
The emergency room facility fee
All physicians who treat you during the emergency (ER doctors, surgeons, anesthesiologists, radiologists)
All services provided during the emergency visit, including lab work, imaging, and medications
Post-stabilization care until you can safely be transferred or discharged
Under the NSA, you can only be charged your in-network cost-sharing amount (your copay, coinsurance, and deductible as defined by your insurance plan). The provider and your insurance company must work out the rest between themselves. You are removed from the middle of that fight.
Real example: Before the NSA, a patient who went to an out-of-network ER for chest pain might receive a bill for $15,000 — the difference between what the ER charged and what insurance paid. Under the NSA, that same patient would only owe their in-network copay (perhaps $250) and deductible. The ER and the insurance company negotiate the rest through the Independent Dispute Resolution (IDR) process.
2. Non-Emergency Services at In-Network Facilities
This is where the Virginia family's situation falls. If you go to an in-network hospital or ambulatory surgical center for a scheduled procedure, you are protected from surprise bills from out-of-network providers at that facility. This commonly happens with:
Anesthesiologists — the most common source of surprise bills
Radiologists — who read your imaging studies
Pathologists — who analyze your lab samples
Assistant surgeons — who may be called in during your procedure
Hospitalists — who manage your care during a hospital stay
Neonatologists — who care for newborns in the NICU
The same rule applies: you can only be charged your in-network cost-sharing amount. The out-of-network provider cannot bill you for the balance.
3. Air Ambulance Services
Air ambulance bills are notoriously astronomical — often $30,000 to $100,000 or more. The NSA protects you from balance billing by out-of-network air ambulance providers. You only owe your in-network cost-sharing amount.
Important note: Ground ambulance services are not covered by the No Surprises Act. This is a significant gap in the law. Ground ambulance bills remain a major source of surprise bills, and several states have enacted their own protections to fill this gap.
What the No Surprises Act Does NOT Cover
This is where many patients get confused. The NSA has important limitations:
| Covered by NSA | NOT Covered by NSA |
|---|---|
| Emergency services at any facility | Non-emergency services at out-of-network facilities you chose |
| Out-of-network providers at in-network facilities | Ground ambulance services |
| Air ambulance services | Services where you signed a written consent to waive NSA protections |
| Post-stabilization care | Urgent care centers (in most cases) |
| Good Faith Estimates for uninsured patients | Bills from providers who are not subject to state/federal regulation |
The biggest gap is the consent waiver. In certain non-emergency situations, an out-of-network provider can ask you to sign a written notice acknowledging that they are out-of-network and that you agree to waive your NSA protections. If you sign this, you lose your protection. My strong advice: never sign a waiver unless you fully understand the financial consequences. If a provider asks you to sign one before a scheduled procedure, ask for time to review it and consult your insurance company first.
Good Faith Estimates: Protection for Uninsured and Self-Pay Patients
One of the lesser-known provisions of the No Surprises Act is the Good Faith Estimate (GFE) requirement. If you are uninsured or plan to pay out of pocket (self-pay), you have the right to receive a written estimate of expected charges before any scheduled service.
Here is how it works:
You schedule a medical service (surgery, imaging, lab work, etc.)
The provider must give you a Good Faith Estimate within **1 business day** of scheduling (or within 3 business days if the service is scheduled more than 10 days out)
The estimate must include all expected charges from all providers involved
If the final bill exceeds the estimate by **$400 or more**, you can dispute the bill through the Patient-Provider Dispute Resolution (PPDR) process
This is a powerful tool. I have had clients use GFEs to comparison shop between facilities and save thousands of dollars. One client needed an MRI and received GFEs ranging from $450 to $2,800 for the exact same scan at different facilities in the same city.
The Independent Dispute Resolution (IDR) Process
When a provider and an insurance company cannot agree on payment for a service covered by the NSA, they enter the Independent Dispute Resolution process. Here is how it works:
The provider sends you a bill that you believe violates the NSA
You (or your insurance company) initiate the IDR process
Both the provider and the insurer submit their proposed payment amounts to an independent arbitrator
The arbitrator selects one of the two amounts (this is called "baseball-style" arbitration — they cannot split the difference)
The losing party pays
The key point for patients: You are not involved in the IDR process. Your cost-sharing amount is locked in at the in-network rate regardless of the outcome. The IDR process is between the provider and the insurer.
However, you may need to initiate the process by contacting your insurance company or filing a complaint with CMS if you receive a bill that violates the NSA.
How to File a Complaint If You Receive a Surprise Bill
If you receive a bill that you believe violates the No Surprises Act, here is the step-by-step process:
**Do not pay the bill immediately.** You have the right to dispute it.
**Call the provider's billing department** and inform them that you believe the bill violates the No Surprises Act. Reference the specific situation (emergency services, out-of-network provider at in-network facility, etc.). Many billing departments will correct the bill at this stage.
**Contact your insurance company** and ask them to reprocess the claim under NSA protections. Ask for a reference number.
**File a complaint with CMS** at 1-800-985-3059 or online at cms.gov/nosurprises. CMS investigates NSA violations and can impose penalties on providers.
**File a complaint with your state Department of Insurance.** Many states have their own surprise billing laws that provide additional protections.
**Send a written dispute letter** to the provider via certified mail, citing the No Surprises Act and requesting that the bill be adjusted to your in-network cost-sharing amount.
Common Loopholes and How to Protect Yourself
The NSA is a strong law, but there are situations where providers try to work around it:
The consent waiver trap: As mentioned above, providers can ask you to waive your NSA protections for non-emergency services. Be very cautious about signing any paperwork that mentions "out-of-network" or "waiver of rights." If you are unsure, write "signed under protest" next to your signature, or simply decline to sign and request an in-network alternative.
The "post-stabilization" gray area: After an emergency, there is a point where you are considered "stabilized." The NSA covers post-stabilization care until you can be safely transferred, but providers sometimes argue that stabilization occurred earlier than it actually did. If you receive a bill for post-emergency care that seems like it should be covered, dispute it.
Facility fee surprises: The NSA does not specifically address facility fees for outpatient services at hospital-owned clinics. You might see an in-network doctor at a hospital-owned office and still receive a facility fee. This is not technically a "surprise bill" under the NSA, but it is still worth disputing.
Ground ambulance bills: As noted, ground ambulances are not covered. If you receive a large ground ambulance bill, check whether your state has its own protections. States like Colorado, Delaware, Florida, Illinois, Maine, Maryland, New York, Ohio, Vermont, and West Virginia have enacted ground ambulance billing protections.
Real Impact: Before and After the No Surprises Act
| Scenario | Before NSA (Patient Owed) | After NSA (Patient Owes) |
|---|---|---|
| ER visit at out-of-network hospital | $8,500 balance bill | In-network copay only (~$250) |
| Out-of-network anesthesiologist at in-network hospital | $4,200 balance bill | $0 additional (in-network cost-sharing only) |
| Air ambulance transport | $32,000 balance bill | In-network cost-sharing only |
| Surprise radiologist bill | $1,800 balance bill | $0 additional |
| Uninsured patient, no estimate given | Full chargemaster rate | Can dispute if bill exceeds GFE by $400+ |
