What Are the Changes Under the 2026 Federal IDR Operations Final Rule?
The Federal No Surprises Act went into effect in 2022. Implementing a law of this scope in the vast and decentralized U.S. healthcare system has required several rounds of regulations and generated multiple court cases. The law protects patients from surprise medical bills by limiting cost sharing and balance billing in specified situations. These include emergency services, certain nonemergency services furnished by out-of-network providers at participating facilities, and air ambulance services.
The Departments of Health and Human Services, Labor, and Treasury, together with the Office of Personnel Management, issued the 2026 Federal IDR Operations final rule. Published in the Federal Register on June 4, 2026, the rule addresses several issues of significant interest to health care providers, health plans, and issuers. It takes effect August 3, 2026.

Final Rule Change |
Key Requirements. |
|---|---|
|
Batching eligible items and services |
Health care providers can batch qualified items and services when initiating the independent dispute resolution (IDR) process in several ways:
|
|
Dispute size and administrative fee |
Providers can submit up to 50 items in a single IDR dispute. The administrative fee owed to the Departments will be lowered from $115 to $15 per party, per dispute. The lower fee applies to disputes initiated on or after June 11, 2026. |
|
Eligibility review timeline |
Under the final rule, certified IDR entities must determine eligibility within five business days after final selection. A disputing party must provide requested additional information within five business days. |
|
QPA and downcoding disclosures |
When sending an initial payment or notice of denial for certain covered claims, plans and issuers must disclose the qualifying payment amount and specified identifying information. If the QPA is based on a downcoded service code or modifier, the payer must identify and explain the change. The payer must also disclose what the QPA would have been without the downcode. |
|
CARCs and RARCs |
Payers are required to utilize specific claim adjustment reason codes (CARCs) or remittance advice adjustment codes (RARCs) when communicating to non-contracted facilities. Note that, at least for now, these codes may vary from payer to payer. |
|
Self-insured plan identification |
Health insurance issuers are required to identify the legal business name of any self-insured group health plans and issuers. |
|
Open negotiation timeline |
A healthcare provider or payer must provide a 30-day open negotiations notice on disputed payment determinations via the Federal IDR Portal. The other party must provide an open negotiation response within 15 days of receiving the original open negotiations notice. |
What led to This New Final Rule?
The short answer is the independent dispute resolution process of the No Surprise Billing rule was plagued with issues. The Centers for Medicare and Medicaid Services (CMS) was inundated with disputes. The IDR process was invoked 489,000 times in its first year of operation, compared to the approximately 22,000 disputes expected to be submitted in the first year. As of January 31, 2026, over 5.1 million disputes had been lodged.
Litigation involving the Texas Medical Association led a United States District Court to vacate portions of earlier rules and guidance, contributing to temporary disruptions in Federal IDR operations.
Nonparticipating providers were dissatisfied with what they considered artificially low qualifying payment amounts from payers. Group health plans and issuers complained that nonparticipating providers did not participate in the open negotiation process. Nonparticipating providers made the same complaint about plans and issuers. CMS also noted parties submitted many disputes that were not eligible for the Federal IDR process.
What should Hospitals and Other Healthcare Providers do to adapt to this new Final Rule?
Like so many issues confronting hospitals and other health care providers, managing a significant regulatory change is a team sport. In this case, you will need participation from revenue cycle leaders, patient financial services professionals, payer contracting, information systems and/or data analysis staff and, of course, Compliance. Here is a list of activities/steps to consider when addressing the effects of the new Final Rule on your organization:
- Review your current policies and procedures related to the No Surprises Act, Good Faith Estimates and use of the IDR Process. If you haven’t done it lately, audit your processes for issuing good faith estimates. Confirm that every patient entitled to an estimate receives it on time.
- Identify significant sources of payments from non-contracted payers. Determine whether contracting with a payer could help avoid excessive Federal IDR claims..
- Review the types and frequency of submissions to the Federal IDR process. Identify recurring claims that may be bundled by type of service or by services furnished to one patient over time. Determine whether those claims have previously been submitted as individual IDR process claims.
- Can you benefit from the capability to submit up to 50 services in a single IDR process?
- Are repeated denials tied to IDR claims that should not have been submitted because they were ineligible? Did other submissions lack adequate information?
- Review rejected IDR disputes to determine the correct pathway for establishing the out-of-network rate. That pathway may be the Federal IDR process, a specified state law, or an All-Payer Model Agreement.
- Update remittance-review workflows to capture the QPA, downcoding disclosures, CARCs and RARCs, legal plan names, and IDR registration numbers. Monitor additional guidance announcing when the remaining requirements become operational.
Why No Surprises Act Compliance Still Requires Attention
The original aims of the No Surprises Act were laudable. One aim was to provide patients with comprehensive and timely good faith estimates. Another was to resolve disputes between health insurance issuers and health care providers.
As we have helped clients with No Surprises Act policies and monitored the runaway expansion of IDR process claims, we continue to encounter challenges in this area.
A patient did not receive a good faith estimate for a service and later received a large bill. The patient submitted a complaint to CMS.
The good news was that our client hospital found a flaw in its internal process. Upcoming visits were not being routed to the financial services staff member responsible for preparing the estimate. CMS closed its file after receiving the hospital’s analysis of the breakdown and confirmation that the patient charges had been written off.
The less good news is that the client hospital now has a record on file with CMS. The next time this happens, the file may not be so readily closed.
Frequently Asked Questions About the No Surprises Act Final Rule provider requirements
No, several major operational requirements will not become applicable on the rule’s August 3, 2026, effective date.
The revised QPA disclosure requirements apply beginning August 3, while the $15 administrative fee applies to disputes initiated on or after June 11, 2026. Changes involving open negotiation, IDR initiation, eligibility review, batching, and the Federal IDR Registry will become applicable later, based on forthcoming guidance and supporting portal functionality.
Providers may batch qualifying claims that satisfy one of three permitted relationships and the rule’s other batching conditions.
The claims may involve one patient during the same encounter, one or more patients billed under the same or comparable service code, or designated anesthesia, radiology, pathology, and laboratory code ranges. A batch may contain no more than 50 qualified items or services. The expanded process will begin only after the Departments announce that supporting functionality is available.
Providers should verify the downcoding explanation and compare the disclosed QPA with the amount that would apply without downcoding.
For a downcoded claim, the payer must identify the altered service code or modifier, explain the change, and disclose the QPA that would have applied without it. Revenue cycle teams should capture this information systematically so coding, contracting, and compliance personnel can evaluate whether the payment should be questioned or negotiated.
Open negotiation will become a more structured, portal-documented process with required notices from both parties.
The initiating party will submit its notice and supporting documentation through the Federal IDR portal, beginning a 30-business-day negotiation period. The receiving party must respond by the 15th business day. These requirements will apply 90 days after the Departments announce that the necessary portal functionality is available.
Providers should confirm the proper dispute-resolution pathway and assemble complete eligibility documentation before initiating Federal IDR.
A claim may instead fall under a specified state law or All-Payer Model Agreement. Providers should verify the plan type, payer identity, QPA, open negotiation history, and required claim information. When an IDR entity requests additional documentation, the responding party generally has five business days to provide it.
No, the reduced administrative fee does not change whether a claim is eligible or economically worthwhile to pursue.
Each party still owes the nonrefundable administrative fee, regardless of the dispute’s eligibility, and certified IDR entity fees and internal processing costs may also apply. Providers should evaluate expected recovery, documentation strength, batching opportunities, and staff effort rather than relying solely on the lower filing fee.
