U.S. health insurers are pushing back against growing challenges to the federal system used to settle out-of-network medical payment disputes, arguing that unchecked arbitration awards and improper claims could ultimately raise healthcare costs for employers and workers.
The fight has intensified after a federal appeals court ruling in August 2026 struck down key parts of the methodology used to calculate the Qualifying Payment Amount, or QPA, a benchmark at the center of the No Surprises Act’s arbitration system.
The dispute highlights a larger battle over how much insurers should pay providers when negotiations fail—and who ultimately absorbs the cost.
No Surprises Act Put Arbitration at the Center
The No Surprises Act was designed to protect patients from certain unexpected out-of-network medical bills.
When an eligible provider and health plan cannot agree on reimbursement, the parties can use the federal Independent Dispute Resolution, or IDR, process.
After a 30-business-day open negotiation period, either side can initiate IDR if an agreement is not reached. A certified independent dispute-resolution organization then determines the payment amount.
Patients are generally kept out of that payment fight.
Insurers Say the System Is Becoming Too Expensive
Insurance groups and employer organizations argue that the IDR system has generated a massive volume of disputes and, in some cases, encouraged providers to seek payments well above what insurers consider reasonable.
The federal process has received more than 5 million disputes since its launch in April 2022, according to federal officials. The volume has contributed to delays and administrative costs.
Insurers have argued that excessive arbitration awards can eventually translate into higher healthcare costs.
Providers Challenge the Payment Benchmark
Healthcare providers have challenged the way insurers calculate the QPA.
The benchmark is generally based on median contracted rates for comparable services and is one of the factors considered in the arbitration process.
Providers have argued that certain federal rules allowed insurers to calculate the benchmark in ways that could suppress reimbursement.
That argument gained momentum after the Fifth Circuit’s August ruling.
Fifth Circuit Ruling Changes the Debate
On August 11, the Fifth Circuit, sitting en banc, ruled in favor of the Texas Medical Association in a major No Surprises Act case.
The court reinstated the lower court’s decision to invalidate two federal rules affecting QPA calculations, including rules concerning so-called “ghost rates”—rates for services that physicians do not actually provide.
The decision represents a significant setback for federal rules that insurers had relied upon in the arbitration framework.
Insurers Say Improper Claims Are Another Problem
Insurance and employer groups are also challenging what they describe as improper or ineligible claims entering the IDR system.
The ERISA Industry Committee and coalition partners recently urged the Ninth Circuit to allow health plans to challenge allegedly fraudulent or ineligible claims connected to the IDR process.
Insurers argue that employers and workers ultimately bear the financial consequences when inappropriate claims result in higher payments.
Providers See Arbitration as an Important Safeguard
Providers view the system differently.
They argue that insurers have substantial negotiating power and that independent arbitration gives physicians and medical organizations a mechanism to challenge reimbursement levels they consider unfair.
For specialists who frequently provide emergency or out-of-network care, the ability to dispute payment can be particularly important.
The Federal Government Is Trying to Fix the Process
Federal agencies finalized new IDR operating rules in May 2026.
The changes are intended to streamline communications between insurers and providers, clarify timelines and reduce administrative problems.
The administration has also reduced the federal IDR administrative fee.
For disputes initiated on or after June 11, 2026, the fee is $15 per party, compared with $115 for disputes initiated during the previous period.
A New Digital System Is Coming
Federal officials are also preparing to replace the current IDR web-form system with a centralized IDR Gateway later in 2026.
The new platform is expected to allow participants to start and respond to disputes, track cases and monitor the status of proceedings through a centralized dashboard.
It will also introduce additional identity-verification and security measures.
Courts Could Shape the Next Phase
The legal fight is not over.
Another case involving Cigna is pending before the Second Circuit after a provider challenged the insurer’s handling of arbitration awards.
An industry coalition has argued that allowing providers to take these disputes directly into federal court could undermine the administrative process Congress created.
That creates another potential turning point for insurers and providers.
Employers Are Closely Watching
Employers have a direct financial interest in the outcome.
Many Americans receive health insurance through their workplaces.
If medical reimbursement costs rise, employers may face higher health-plan expenses, potentially leading to increased premiums, deductibles or other employee costs.
That is why employer groups have become increasingly vocal about the arbitration debate.
Consumers Remain at the Center
The No Surprises Act was created primarily to protect patients.
The law generally prevents eligible patients from becoming responsible for the difference between an insurer’s payment and a provider’s out-of-network charge.
But consumers can still be affected indirectly.
If insurers face higher claims costs, those expenses can eventually influence premiums and other healthcare costs.
The Industry Faces a Difficult Balance
The central challenge is finding a system that protects providers from inadequate reimbursement without allowing arbitration to become a mechanism for excessive payments.
Insurers want predictable costs.
Providers want fair reimbursement.
Employers want affordable health coverage.
Patients want protection from unexpected bills.
The IDR system has to balance all four interests.
What Comes Next
The federal government is already changing how the arbitration system operates, while courts continue to determine whether specific rules comply with the No Surprises Act.
The Fifth Circuit’s latest ruling could force regulators to revisit important aspects of the QPA methodology. Meanwhile, insurers and employer groups are continuing to challenge what they view as abusive or improper use of the arbitration process.
The coming months could therefore bring further regulatory changes and additional litigation.
A Bigger Fight Over Healthcare Costs
The battle over medical payment arbitration is ultimately about more than a technical insurance rule.
It is a fight over how healthcare prices are established when insurers and providers cannot reach an agreement.
The No Surprises Act removed patients from many of those disputes, but it did not eliminate the underlying disagreement over what medical care should cost.
As insurers defend their approach and providers challenge payment calculations, the outcome could have consequences well beyond arbitration.
The next phase of the No Surprises Act fight could influence provider revenues, insurer costs, employer health plans and, ultimately, what Americans pay for health coverage.
