[Your Name] [Your Email Address] June 15, 2026 [Provider/Billing Entity Name] Billing Department [Provider Address, City, State, ZIP Code] Re: Dispute of Balance Bill / Surprise Bill Account Number: [Account Number] Date of Service: [Date of Service] Facility: [Hospital/Facility Name] Dear Billing Department, I am writing to formally dispute the balance bill I received for services provided on [Date of Service] at [Hospital/Facility Name]. I believe this bill violates the No Surprises Act (Public Law 116-260, Division BB, Title I) and I should not be responsible for the balance billed amount. BILLING DETAILS Total Amount Billed: $[Total Amount Billed] Amount Paid by Insurance ([Insurance Company]): $[Amount Insurance Paid] Balance Billed to Me: $[Balance Amount You Are Being Asked to Pay] WHY THIS BILL IS PROHIBITED I received emergency medical services and did not have the ability to choose an in-network provider. Under the No Surprises Act, emergency services are protected regardless of network status, and I cannot be billed more than the in-network cost-sharing amount. Specifically, the No Surprises Act (effective January 1, 2022) provides the following protections: 1. For emergency services: Patients cannot be balance billed for emergency care, regardless of whether the provider or facility is in-network. Cost-sharing must be based on in-network rates. 2. For non-emergency services at in-network facilities: Out-of-network providers who treat patients at in-network facilities cannot balance bill the patient unless specific notice and consent requirements are met at least 72 hours before the service. 3. I did not provide written consent to waive my balance billing protections, and I did not receive the required advance notice that an out-of-network provider would be involved in my care. WHAT I AM REQUESTING I respectfully request that you: 1. Immediately withdraw the balance bill of $[Balance Amount] and adjust my account accordingly 2. Accept the amount paid by my insurance as payment in full for these services, or resolve any remaining payment dispute directly with my insurance company through the independent dispute resolution (IDR) process as provided by the No Surprises Act 3. Confirm in writing within 14 business days that this balance has been removed from my account 4. Refund any payments I have already made toward this balance billed amount 5. Not report this disputed amount to any credit bureau or collection agency REGULATORY NOTICE If this balance bill is not corrected, I intend to file a complaint with: - The U.S. Department of Health and Human Services (HHS) at 1-800-985-3059 - The Centers for Medicare and Medicaid Services (CMS) No Surprises Help Desk - My state insurance commissioner - The Consumer Financial Protection Bureau (CFPB) if this account is sent to collections Please send all correspondence to [Your Email Address] or the address above. I expect a written response within 14 business days. Sincerely, [Signature] [Your Name] Enclosures: - Copy of the balance bill - Explanation of Benefits (EOB) showing insurance payment - Any relevant correspondence from insurance company Sent via certified mail, return receipt requested

Frequently Asked Questions
What is balance billing and when is it illegal?
Balance billing occurs when an out-of-network provider bills you for the difference between their charge and what your insurance paid. Under the No Surprises Act, this is prohibited for emergency services, for out-of-network providers at in-network facilities, and for air ambulance services. You can only be charged your normal in-network cost-sharing.
What is the No Surprises Act?
The No Surprises Act is a federal law effective January 1, 2022 that protects patients from surprise medical bills. It requires that patients only pay in-network cost-sharing amounts and establishes an independent dispute resolution process for providers and insurers to settle payment disagreements without involving the patient.
How do I know if my bill is an illegal balance bill?
Your bill may be an illegal balance bill if you received emergency care from an out-of-network provider, if you were treated by an out-of-network provider at an in-network facility without advance notice and written consent, or if you did not sign a separate written waiver at least 72 hours before a scheduled procedure. Compare the bill to your EOB and in-network cost-sharing obligations.
Where can I file a complaint about balance billing?
File a complaint with the No Surprises Help Desk at 1-800-985-3059 or through the CMS online portal. Also file with your state insurance commissioner, as many states have additional surprise billing protections. If the disputed amount is sent to collections, file with the CFPB.
Can I ever be balance billed for elective procedures?
In limited situations, yes. A provider can balance bill for scheduled non-emergency services at an out-of-network facility if they give written notice and a good faith cost estimate at least 72 hours before the procedure and you sign a separate consent form agreeing to waive protections. Without both proper notice and signed consent, balance billing is prohibited.
