The Problem
When you receive care from a provider who doesn't have a contract with your insurance, they're 'out-of-network.'These providers can charge whatever they want, and your insurance may pay little or nothing - leaving you with a huge 'balance bill' for the difference.
The Solution
The No Surprises Act protects you from most out-of-network bills in emergencies and at in-network facilities. You only owe your in-network cost-sharing amount. Providers must work with your insurer to resolve payment differences.
Common Reasons for Out-of-Network Bills
- 1Emergency Room Visit - ER physicians, radiologists, or anesthesiologists are out-of-network. Affects 20% of ER visits. Protected by No Surprises Act.
- 2Hospital-Based Specialists - Anesthesiologists, pathologists, radiologists at in-network hospital are OON. Affects 16% of hospitalizations.
- 3Air Ambulance - Emergency air transport, often $30,000-$50,000+. Most air ambulances are OON. Protected by No Surprises Act.
- 4Referral to OON Specialist - In-network doctor refers you to out-of-network specialist. Not always protected - ask for in-network referral.
- 5Imaging/Lab at OON Facility - Doctor sends your tests to an out-of-network lab or imaging center.
How to Respond: Step-by-Step
Determine if you're protected
The No Surprises Act covers most emergency and some non-emergency out-of-network situations at in-network facilities. Emergency services are protected regardless of network status. Non-emergency services at in-network facilities from OON providers are often protected.
Request an itemized bill
Get a detailed breakdown of every charge. This helps identify errors and negotiate effectively. Request CPT codes for each service, compare charges to fair market rates, and look for duplicate or incorrect charges.
Know your maximum liability
Under the No Surprises Act, you should only pay what you'd pay for in-network care (deductible, copay, coinsurance). Check your EOB for the in-network rate. If billed more, dispute as a No Surprises Act violation.
Negotiate or dispute the bill
Even if not fully protected, you can often negotiate significant reductions on out-of-network charges. Offer to pay 150-200% of Medicare rates, reference fair market rates from FAIR Health, and ask for the cash/self-pay rate as a baseline.
File formal complaints if needed
If providers or insurers violate the No Surprises Act, file complaints with CMS at 1-800-985-3059 and your state insurance commissioner. Document all communications.

Frequently Asked Questions
What is the No Surprises Act and how does it protect me?
The No Surprises Act (2022) protects patients from surprise out-of-network bills for emergency services, air ambulance from OON providers, and non-emergency services at in-network facilities from out-of-network providers. You only pay your in-network cost-sharing amount.
Can an out-of-network doctor still bill me directly?
In protected situations (emergencies, in-network facilities), they cannot balance bill you. They must work with your insurer to resolve payment through arbitration. You only owe your in-network cost-sharing.
What if I chose to go out-of-network?
If you knowingly chose an out-of-network provider (elective surgery, scheduled specialist visit), the No Surprises Act may not protect you. However, you can still negotiate the bill using fair market rates.
How do I know what the 'in-network' rate should be?
Check your Explanation of Benefits (EOB) from insurance - it shows what they would pay in-network. You can also look up median rates at fairhealth.org or use 150-200% of Medicare rates as a benchmark.
Can I be sent to collections for a disputed out-of-network bill?
While disputing, request a billing hold. Under the No Surprises Act, providers generally cannot send protected bills to collections while disputes are pending. Document your dispute in writing.
What about ground ambulance bills?
Unfortunately, ground ambulance is NOT covered by the No Surprises Act (only air ambulance is covered). However, many states have their own ambulance billing protections, and you can still negotiate.
