Federal Rule on Independent Dispute Resolution Enhances Claims Transparency
On May 28, 2026, the U.S. Departments of Health and Human Services, Labor, and the Treasury issued the final rule on Federal Independent Dispute Resolution (IDR) Operations. This update addresses various technical challenges that stakeholders have encountered since the No Surprises Act's implementation. The rule aims to streamline the process for determining dispute eligibility and managing related claims.
Central to the final rule are new disclosure requirements for group health plans and insurance issuers. These entities must provide specific information at the initial payment stage or when a payment is denied, including the plan's business name, sponsor name (if applicable), and the health plan's registration ID in the new IDR registry.
The rule also mandates the use of standardized claim adjustment reason codes (CARCs) and remittance advice remark codes (RARCs). This requirement is designed to streamline communications, particularly with entities that do not have contractual relationships with the issuer. These measures intend to enhance transparency and simplify the claims processing from the outset.
To further facilitate the IDR process, plans and issuers impacted by federal IDR rules must submit detailed information into a centralized registry. This initiative allows parties to readily confirm claim eligibility for federal intervention. Moreover, the rule demands additional data on the IDR initiation notice to address discrepancies affecting eligibility, with a three business day response time once an IDR process is initiated.
Certified IDR entities are granted an additional two business days, totaling five, to determine a dispute's eligibility. The concept of an "IDR gateway," although not part of the current rule, was discussed as a potential future digital platform to optimize dispute management.
Aligning with the No Surprises Act, the rule enforces a 30-day open negotiation period to enhance efficiency. The rule introduces changes to the notification process during negotiations, requiring more comprehensive content and the use of the federal IDR portal for all notices and responses.
The rule modifies "batching" provisions, allowing providers to bundle multiple claims into a single batch if they meet specific criteria. The adjusted batch size cap is now 50 items, increased from the initially proposed 25, reflecting stakeholder feedback. Additionally, amendments address the 30-business-day "cooling off" period post-dispute determinations, with guidance on handling perpetual extensions.
Importantly, improperly batched disputes can no longer be resubmitted after a set deadline. The administrative fee schedule has been revised, reducing the fee from $115 to $15, informed by updated budget and dispute projections. The rule permits timeline extensions under extenuating circumstances, with public notices for any general time extensions. While these updates aim for improvements, implementation details depend on future guidance and timeline clarifications. The rule becomes effective 60 days post-publication in the Federal Register, though many elements will require additional guidance for full enactment.
