Navigating the No Surprises Act’s Independent Dispute Resolution (IDR): A Guide for Nonparticipating Medical Professionals

17 Jun 2025 Beinhaker Law

The No Surprises Act (NSA), which took effect on January 1, 2022, has significantly changed the way healthcare billing disputes are handled in the United States. One of the most important aspects of the NSA is the Independent Dispute Resolution (IDR) process, which is designed to settle payment disputes between healthcare providers and insurers when patients receive out-of-network care under specific circumstances.

For nonparticipating medical professionals, understanding how the IDR process works is essential to navigating this new regulatory landscape. The process affects how disputes over reimbursement are resolved and determines how much out-of-network providers can be paid. This guide explains the IDR process, its implications for medical professionals, and the role legal professionals play in helping providers navigate these arbitrations.

Understanding the Independent Dispute Resolution (IDR) Process

The IDR process was introduced as a key part of the No Surprises Act to prevent patients from being burdened with surprise medical bills while ensuring fair payment practices between insurers and healthcare providers. It serves as a formal mechanism for resolving disputes when providers and insurers cannot agree on reimbursement amounts.

When Does the IDR Process Apply?

The IDR process can be used in disputes that involve:

  • Emergency services provided at an out-of-network facility or by an out-of-network provider.
  • Non-emergency services received from an out-of-network provider at an in-network facility when the patient was not given proper notice or did not consent to out-of-network treatment.
  • Air ambulance services provided by an out-of-network entity.

In these cases, balance billing is restricted, meaning providers cannot charge patients more than the in-network cost-sharing amount, and disputes over payments must be settled between the provider and insurer through negotiation or the IDR process.

Steps in the IDR Process

The IDR process follows a structured timeline and includes several key phases:

  1. Open Negotiation Period
    After the provider receives the initial payment offer or a denial from the insurance plan, both parties have 30 days to negotiate a mutually acceptable payment amount. If no agreement is reached within this timeframe, either party may initiate the IDR process.
  2. Submission to IDR
    If negotiations fail, the initiating party must submit a formal arbitration request within four days through the federal IDR portal. Both the provider and insurer must submit their proposed payment amounts along with supporting documentation.
  3. Arbitrator Selection
    A neutral third-party arbitrator, approved by the Department of Health and Human Services (HHS), is assigned to the case to evaluate the dispute and determine a fair payment amount.
  4. Arbitration Decision
    The arbitrator considers several factors before making a decision, including:
    • The median in-network rate for similar services.
    • The provider’s qualifications and experience.
    • The market share and negotiating leverage of both parties.
    • The complexity of the medical case.

The arbitrator must make a decision within 30 days and is required to select one of the proposed payment amounts rather than proposing a compromise.

  1. Payment and Fees
    Once a decision is made, the losing party must pay the arbitrator’s fees, which typically range from $200 to $500 per arbitration. The final payment amount must be processed within the specified legal timeframe.

How IDR Affects Nonparticipating Medical Professionals

The No Surprises Act has introduced limitations on balance billing, meaning nonparticipating providers must often accept payment amounts determined through the IDR process. This change has introduced several challenges for out-of-network providers.

Limitations on Balance Billing

Under the NSA, nonparticipating providers cannot charge patients more than the in-network cost-sharing amount for:

  • Emergency services, even if the provider is out-of-network.
  • Non-emergency services provided at an in-network facility when the patient did not provide written consent to receive treatment from an out-of-network provider.

As a result, providers are frequently forced to accept lower reimbursement rates set by insurers or resolved through IDR arbitration.

Challenges Faced by Nonparticipating Providers

The IDR process, while offering an avenue for challenging low reimbursement rates, presents several challenges for medical professionals.

One major issue is disparities in payment offers, as many providers find that insurers’ initial reimbursement amounts are significantly lower than expected. This often forces providers to engage in arbitration, which can be a time-consuming and resource-intensive process.

Additionally, the administrative burden of submitting an IDR request is substantial. The process requires extensive paperwork, supporting evidence, and adherence to strict deadlines. Providers must be prepared to submit documentation within a narrow timeframe, making it essential to maintain detailed billing records and cost data.

Another challenge is the uncertainty of arbitration outcomes. Arbitrators have broad discretion in selecting a final payment amount, and decisions can be unpredictable. The lack of clear, consistent guidelines can make it difficult for providers to anticipate the results of an IDR claim.

Given the complexity of the IDR process, many non-participating medical professionals turn to legal experts to help manage disputes and improve arbitration outcomes.

Strategic Case Preparation

Legal professionals assist providers in building a strong case by:

  • Gathering cost data, patient demographics, and evidence of service complexity.
  • Highlighting factors that justify a higher reimbursement rate, such as provider expertise and market conditions.

Ensuring Compliance with Regulations

Attorneys help providers navigate the legal requirements of the NSA, ensuring compliance with:

  • Filing deadlines for IDR submissions.
  • Accurate documentation to support payment disputes.
  • Procedural guidelines that, if ignored, could lead to case dismissal.

Negotiating with Insurers

Before resorting to arbitration, legal professionals can assist providers in negotiating directly with insurers. Skilled negotiators may be able to secure a fair payment agreement without the need for formal arbitration, saving both time and legal expenses.

Representation During Arbitration

If an IDR case moves forward, legal professionals provide representation during arbitration, ensuring that providers’ arguments and supporting evidence are effectively presented. Having an experienced attorney can significantly increase the chances of a favorable ruling.

Managing Multiple Disputes

For providers dealing with frequent payment disputes, legal professionals streamline the process by managing arbitration timelines, handling correspondence with insurers and arbitrators, and ensuring compliance with regulatory requirements.

Best Practices for Nonparticipating Providers in IDR Arbitrations

To improve the likelihood of successful IDR outcomes, nonparticipating providers should adopt best practices when handling reimbursement disputes.

Maintaining detailed records of initial payment offers, negotiation communications, and supporting medical evidence is crucial. Organized documentation helps build a stronger case during arbitration.

Investing in legal support can also maximize success rates, ensuring that disputes are handled efficiently and in compliance with NSA requirements.

Additionally, leveraging technology and billing management software can streamline IDR submissions and track arbitration timelines effectively.

Conclusion

The No Surprises Act has reshaped the healthcare reimbursement landscape, protecting patients from unexpected bills while introducing the Independent Dispute Resolution (IDR) process for payment disputes.

For nonparticipating medical professionals, the IDR process provides an opportunity to challenge unfair reimbursement rates, but it also presents significant administrative and legal challenges.

By working with legal professionals, maintaining organized billing records, and adopting best practices for dispute resolution, providers can navigate the IDR process more effectively and secure fair compensation for their services.
