The Federal Independent Dispute Resolution (IDR) process established by the No Surprises Act (NSA) was intended to be the final word in payment disputes between insurers and out-of-network providers, particularly for services like emergency air ambulance transport. However, a landmark ruling by the U.S. Court of Appeals for the Fifth Circuit has revealed a systemic flaw: the law’s silence on judicial remedies for non-payment. This decision, which found that providers have no private right of action to enforce IDR awards, places the burden of ensuring compliance squarely on federal regulators and challenges the perceived binding nature of the NSA’s core resolution mechanism.

The No Surprises Act, effective since 2022, protects consumers from “surprise billing” by limiting their financial responsibility for out-of-network emergency care, including air ambulance services, to their in-network cost-sharing amount. The law established the IDR process, a mandatory “baseball-style” arbitration, for providers and payers to determine the final reimbursement rate. Crucially, the statute declares that an IDR award “shall be binding” on the parties and must be paid within 30 days. Yet, in Guardian Flight LLC v. Health Care Service Corp., air ambulance providers sued the insurer for allegedly failing to pay numerous IDR awards.

In June 2025, the Fifth Circuit affirmed a lower court’s dismissal of the case, holding that the NSA does not contain an explicit or implied private right of action for providers to compel payment. The court reasoned that Congress intended the Department of Health and Human Services (HHS) to be the sole enforcement body, channeling non-compliance through an administrative complaint process. This interpretation rejects the argument that a “binding” award inherently implies a judicial remedy for its enforcement. This ruling creates a direct split with at least one other federal district court, which found an implied right of action to prevent the IDR process from becoming meaningless, signaling that the question of IDR enforceability is likely headed for review by the Supreme Court.

Key Findings and Data Analysis of Air Ambulance IDR Outcomes

The financial stakes of this legal dispute are substantial and are illustrated by current IDR data. Air ambulance providers, who are frequently out-of-network due to the urgent and mobile nature of their service, have been highly successful in the IDR process. Analysis of 5,678 air ambulance IDR cases arbitrated in 2023 shows that air ambulance organizations prevailed in 86.4% of disputes against insurers. For the cases where financial data was reported, the average winning offer was $32,463, which was 2.95 times the Qualifying Payment Amount (QPA)—the insurer’s median contracted rate—used as a baseline reference point in the negotiation. These figures demonstrate that providers frequently receive final payment amounts substantially higher than the in-network negotiated rate benchmarks used by payers, highlighting why the prompt and reliable enforcement of these awards is critical to provider solvency and, by extension, service availability.

  • Air ambulance providers won 86.4% of IDR disputes in 2023.
  • The average prevailing offer was $32,463.
  • The average winning offer was 2.95 times the QPA.

Furthermore, private equity-backed air ambulance organizations were involved in over 60% of the IDR cases, and their prevailing offers relative to the QPA were typically higher than those of non-PE providers, indicating that the stakes are particularly high for these sophisticated, frequent litigants.

Systemic Implications and Outlook

The Fifth Circuit’s holding poses a direct challenge to the integrity of the NSA’s enforcement regime. By eliminating the ability for a winning provider to compel payment through the courts, the ruling effectively converts the binding IDR award into a resolution that relies solely on administrative oversight, which can be slow and resource-intensive. This creates a moral hazard: an insurer can choose to delay or ignore an IDR payment, knowing the provider’s only recourse is to file a complaint with HHS, a less immediate and potentially less effective remedy than judicial enforcement.

While patients remain shielded from balance billing for surprise billing, the uncertainty introduced by this enforceability gap could have cascading systemic effects. Over time, delayed payments or a loss of faith in the process could affect the financial stability of providers, potentially impacting the availability of critical emergency services, especially in rural or underserved regions. The future of this core pillar of the No Surprises Act now rests on whether the Supreme Court agrees to address the circuit split and clarify Congress’s intent regarding judicial enforcement of this landmark consumer protection legislation.

The Takeaway

The Fifth Circuit’s definitive ruling that the No Surprises Act does not provide a private right of action to enforce IDR awards creates a profound enforcement gap in federal healthcare transparency law. The analysis of air ambulance IDR data underscores the significant financial sums involved, where providers are successfully demonstrating that fair payment often exceeds the Qualifying Payment Amount. Without judicial clarity on enforcement, the effectiveness of the IDR process is undermined, shifting the burden of systemic compliance enforcement entirely to federal agencies and leaving the fundamental question of payment reliability unresolved.
