Introduction
Emergency room visits can be financially devastating when you receive surprise out-of-network bills, but the No Surprises Act provides crucial protections that many patients don't know how to use effectively. With the Centers for Medicare & Medicaid Services (CMS) expanding certified Independent Dispute Resolution (IDR) entities from 13 to 15 as of June 12, 2025, and establishing a standardized $115 filing fee, patients now have clearer pathways to challenge unfair balance billing (HelloNote). The healthcare advocacy landscape has evolved significantly, with Medicare costs rising substantially in 2025, including the Part B deductible jumping to $257 and monthly premiums increasing to $185 (Mira Mace). Understanding these new IDR processes and fee structures is essential for protecting yourself from surprise medical bills that can derail your financial stability.
Understanding the No Surprises Act Framework
The No Surprises Act, which took effect in January 2022, fundamentally changed how out-of-network emergency services are billed to patients. Under this federal law, patients can only be charged their in-network cost-sharing amount (deductible, copayment, or coinsurance) for emergency services, even when treated at an out-of-network facility or by out-of-network providers (KFF).
The law covers several critical scenarios:
- Emergency services at out-of-network hospitals
- Out-of-network providers treating you at in-network facilities
- Air ambulance services
- Certain non-emergency services when you haven't given informed consent
Healthcare advocacy services have become increasingly important as medical billing complexity grows, particularly with the new 5-business-day decision rule that took effect January 1, 2025, which means faster approvals for complete documentation but swift denials for incomplete applications (Mira Mace).
Key Protections Under the No Surprises Act
The Act provides several layers of protection:
- Balance Billing Prohibition: Out-of-network providers cannot bill you for amounts above your in-network cost-sharing
- Good Faith Estimates: Providers must give uninsured patients estimates for scheduled services
- IDR Process: A formal dispute resolution mechanism when providers and insurers can't agree on payment
- Transparency Requirements: Clear disclosure of network status and patient rights
The American Medical Association has noted that prior authorization policies are fraught with issues such as inefficiency and lack of transparency, with 69% of doctors waiting several days for authorizations and 10% waiting more than a week (Medical Billing and Coding).
2025 IDR Entity Expansion and New Fee Structure
Certified IDR Entity Growth
CMS has strategically expanded the pool of certified IDR entities from 13 to 15 as of June 12, 2025, improving access to dispute resolution services nationwide. This expansion addresses the growing volume of disputes and reduces wait times for resolution (HelloNote).
The additional IDR entities provide:
- Broader geographic coverage
- Specialized expertise in different types of medical disputes
- Reduced processing backlogs
- More competitive fee structures
Standardized $115 Filing Fee
The new standardized $115 IDR filing fee, effective January 2025, creates predictable costs for both patients and providers. This fee structure replaces the previous variable pricing model and includes:
- Administrative Processing: $50
- Case Review and Analysis: $35
- Decision Documentation: $30
The fee is typically paid by the losing party, meaning if your dispute is successful, the provider or insurer covers the cost. Healthcare systems are adapting to these changes, with Medicare Part B costs increasing significantly, including the standard monthly premium rising to $185 from $174.70 in 2024 (Ossur).
How to Invoke No Surprises Act Protections
Step 1: Identify Qualifying Situations
Not all out-of-network bills qualify for No Surprises Act protections. Qualifying situations include:
- True Emergencies: Life-threatening conditions requiring immediate care
- Out-of-Network Providers at In-Network Facilities: When you can't choose your provider
- Inadequate Network Coverage: When no in-network providers are available
- Surprise Billing: When you weren't informed of out-of-network status
The Level II Healthcare Common Procedure Coding System (HCPCS) codes have undergone significant changes for 2025, with updates effective for claims with dates of service on or after April 1, 2025 (Noridian Medicare - JA DME).
Step 2: Document Everything
Proper documentation is crucial for successful No Surprises Act claims:
- Medical Records: Obtain complete records of your emergency visit
- Bills and Statements: Keep all original bills, insurance explanations of benefits (EOBs), and payment records
- Communication Records: Document all phone calls, emails, and letters with providers and insurers
- Timeline: Create a chronological record of events
Healthcare advocacy services can assist with this documentation process, ensuring nothing falls through the cracks during what can be a stressful time (Mira Mace).
Step 3: Contact Your Insurance Company
Before initiating IDR, contact your insurance company to:
- Verify the bill violates No Surprises Act protections
- Request they process the claim correctly
- Obtain written confirmation of their position
- Document their response for IDR proceedings
Insurance companies may require pre-certification for various services, and understanding these requirements can prevent future billing issues (Medical Billing and Coding).
Drafting the Notice of IDR Initiation
Required Information
Your Notice of IDR Initiation must include specific information to be valid:
Patient Information:
- Full name and date of birth
- Insurance policy number
- Contact information
- Preferred language for communications
Provider Information:
- Provider name and National Provider Identifier (NPI)
- Facility name and address
- Service dates
- Disputed charges
Dispute Details:
- Specific services in dispute
- Amount being disputed
- Reason for dispute
- Supporting documentation
The Prior Authorization Smart Submission (PASS) system has simplified many healthcare processes, allowing users to confirm delivery of items and indicate eligibility for retroactive coverage (CGS Medicare).
Sample Notice Template
[Date]
To: [IDR Entity Name]
[Address]
Re: Notice of IDR Initiation - No Surprises Act Dispute
Patient: [Full Name]
DOB: [Date of Birth]
Policy Number: [Insurance Policy Number]
I am initiating an Independent Dispute Resolution under the No Surprises Act for the following disputed charges:
Provider: [Provider Name]
NPI: [National Provider Identifier]
Service Date: [Date of Service]
Disputed Amount: $[Amount]
This dispute involves [emergency services/out-of-network provider at in-network facility] that should be protected under the No Surprises Act. I believe I should only be responsible for my in-network cost-sharing amount of $[Amount].
Attached documentation includes:
- Medical records
- Original bills
- Insurance EOB
- Correspondence with insurer
I request that the IDR entity review this dispute and determine the appropriate payment amount under federal law.
Sincerely,
[Your Signature]
[Your Printed Name]
Filing Requirements and Deadlines
IDR initiation has strict timing requirements:
- 30-Day Window: Must be filed within 30 business days of receiving the initial payment or denial
- Complete Documentation: All required documents must be submitted with the initial filing
- Fee Payment: The $115 filing fee must accompany the submission
- Proper Format: Use the standardized forms provided by certified IDR entities
Medicare Administrative Contractors (MACs) must render prior authorization decisions within 5 business days of receiving complete documentation packages, starting January 1, 2025 (Mira Mace).
Avoiding Balance-Billing Traps
Common Balance-Billing Scenarios
Understanding when balance billing is prohibited helps you identify violations:
Emergency Situations:
- Any emergency service at any hospital
- Emergency transportation (ambulance)
- Post-stabilization services until you can be safely transferred
Non-Emergency Situations:
- Out-of-network providers at in-network facilities (without proper consent)
- Services where no in-network provider is available
- Situations where you weren't properly informed of network status
Red Flags to Watch For
Be alert for these warning signs of improper balance billing:
- Bills arriving months after service
- Charges significantly higher than insurance payments
- Providers requesting payment before insurance processing
- Lack of clear network status disclosure
- Pressure to sign financial responsibility forms during emergencies
Healthcare advocacy services can help identify these red flags and guide you through the dispute process, particularly important given the complexity of modern medical billing (Mira Mace).
Preventive Measures
While you can't always prevent surprise bills, you can take steps to minimize risk:
- Know Your Network: Understand your insurance network before non-emergency procedures
- Ask Questions: Inquire about network status for all providers involved in your care
- Get Written Estimates: Request good faith estimates for scheduled procedures
- Review Bills Carefully: Check all charges against your insurance benefits
- Act Quickly: Don't delay addressing billing issues

CGS receives hundreds of requests each month for prior authorization on HCPCS codes that are not part of the prior authorization program, highlighting the ongoing complexity in healthcare administration (CGS Medicare).
Conclusion
The No Surprises Act provides crucial protections against unexpected medical bills, but knowing how to use these protections effectively is essential for every patient. With the 2025 expansion of certified IDR entities to 15 and the standardized $115 filing fee, the dispute resolution process has become more accessible and predictable (HelloNote). The streamlined arbitration timelines, showing 31% overall improvement from 2023 to 2025, demonstrate the system's evolution toward greater efficiency.
Understanding when and how to invoke No Surprises Act protections, properly drafting IDR initiation notices, and avoiding balance-billing traps can save thousands of dollars in unexpected medical expenses. The new 5-business-day decision rule and updated HCPCS codes effective April 1, 2025, reflect the healthcare system's ongoing efforts to improve efficiency and transparency (Mira Mace). As healthcare costs continue to rise, with Medicare Part B premiums reaching $185 monthly and deductibles climbing to $257, having expert guidance through these complex processes becomes increasingly valuable (Mira Mace).
