The Centers for Medicare & Medicaid Services (CMS) finalized updates to the No Surprises Act (NSA) Independent Dispute Resolution (IDR) process on May 28, 2026. These updates represent one of the most significant changes since the program took effect in 2022.11
The modifications seek to reduce administrative burden, improve transparency, and address the growing volume of payment disputes between providers and health plans. While these reforms introduce new compliance requirements, their broader impact is operational, creating opportunities for health plans to modernize payment, dispute-management, and provider communication processes.
Small and mid-market plans can turn CMS IDR changes into an operational advantage by treating compliance as a catalyst for modernizing operations rather than simply a regulatory requirement.

Why the Changes Matter
Since the program began, over five million disputes have been filed, creating backlogs, administrative complexity, processing delays, and rising costs across the system.
Updates reflect CMS’s efforts to improve efficiency while maintaining access to a fair and transparent dispute resolution process.
Key provisions of the reforms include:
- A reduction of the federal administrative dispute fee from $115 to $15 per party per dispute.
- New payer registration requirements in the federal IDR portal system. The platform will be rolled out in phases throughout 2026.
- A more structured open-negotiation process conducted through the federal IDR portal that will allow participants to initiate disputes, track case status, and manage dispute-related activities in one place.
- New requirements for health plans to provide standardized remittance information using specific Claim Adjustment Reason Code (CARC) and Remittance Advice Remark Code (RARC) codes that identify whether a claim is subject to NSA protections and IDR.
- Expanded disclosure requirements when plans issue an initial payment or denial, including additional information about the plan and qualifying payment amount (QPA).
Expected Impact on Small and Mid-Market Plans
1. Potential increase in dispute volume
The reduction in the administrative filing fee from $115 to $15 lowers the barrier for providers to pursue arbitration, especially on lower-dollar claims that may previously have been uneconomical to challenge. As a result, some plans could see more disputes entering the IDR process.
2. Increased administrative and compliance requirements
Smaller regional plans, provider-sponsored plans, and self-funded employer plans may need to invest in claims-system modifications, CARC and RARC coding updates, IDR portal registration, and enhanced documentation processes.
3. Preparation for Stronger Open Negotiation
The revised open-negotiation process introduces standardized submissions through the federal portal and more detailed notice requirements, placing greater emphasis on consistency, accountability, and process management. Key capabilities include:
- Structured negotiation workflows
- Standardized documentation practices
- Clearly defined response timelines and ownership
Without these controls, plans risk missed deadlines, inconsistent outcomes, and higher arbitration rates.
4. Greater transparency around QPA calculations
Plans will be required to provide more detailed information supporting payment determinations and QPA calculations. This process may increase provider scrutiny of out-of-network reimbursement methodologies and create additional operational workload for payer payment integrity, legal, and provider relations teams.
5. Reduced spending on ineligible disputes
CMS expects standardized communications and eligibility indicators to reduce the number of disputes that are ultimately found to be ineligible. For smaller plans that lack large dispute-management teams, this could lower wasted administrative effort and legal expenses.
6. Continued pressure on out-of-network reimbursement costs
While the 2026 rule addresses operations rather than fundamental payment methodology, plans should expect ongoing provider challenges through the IDR process. The underlying debate over QPA calculations and arbitration outcomes remains active, meaning reimbursement pressure is unlikely to disappear.
Looking Ahead
One thing is becoming increasingly clear: the No Surprises Act is reshaping how health plans manage reimbursement disputes, provider relationships, and operational compliance.
For small- and mid-market plans, the more pressing issue is not the regulation itself, but whether their operating models can keep pace with the evolving IDR process.
Success will depend on how effectively organizations adapt their processes, improve coordination, and build more efficient ways of managing disputes. Health plans that invest in efficient workflows, stronger provider collaboration, and more disciplined oversight will be better positioned to manage compliance requirements while controlling administrative costs over the long term.
Making the Most of the Operational Advantage
While compliance remains the immediate priority, forward-looking health plans are using NSA requirements as a catalyst for operational modernization.
By integrating workflow management, payment integrity expertise, provider engagement, and analytics, plans can resolve disputes earlier and reduce reliance on arbitration. At the same time, better insights into denial trends, negotiation outcomes, and provider patterns enable continuous improvement in reimbursement strategies and operational efficiency.
The latest CMS IDR reforms are more than regulatory updates. They provide health plans with an opportunity to strengthen operational foundations, improve payment transparency, and create more efficient dispute-management processes. For small- and mid-market plans in particular, the organizations that move beyond a compliance mindset and embrace operational modernization will be best positioned to control costs, improve provider relationships, and navigate future regulatory change with confidence.
