The federal Independent Dispute Resolution process under the No Surprises Act has become a meaningful revenue source for out-of-network providers, and most are not using it. Per the CMS IDR public reports, providers prevailed in 88 percent of disputes that reached payment determination across recent reporting periods, with successful providers paid roughly 3 to 4 times comparable in-network rates. CMS also announced in March 2026 that the IDR process will transition to a new centralized Gateway platform in late 2026, replacing the current single-use web forms. For practices that have written off underpaid out-of-network claims, the time to build IDR workflow is now.
Who can initiate IDR and when
IDR applies to most out-of-network emergency services, out-of-network items and services furnished at in-network facilities, and out-of-network air ambulance services. The process begins with the 30-day open negotiation period after the initial payment or denial. If negotiation does not resolve the dispute, either party can initiate IDR within 4 business days of the negotiation period closing. The provider selects a certified IDR entity from the CMS-published list (which now includes 16 entities, with Dane Street, LLC added in January 2026) and submits the dispute, along with a proposed payment amount and supporting documentation.
The Qualifying Payment Amount and what beats it
The IDR entity considers the Qualifying Payment Amount (QPA), which is essentially the median in-network rate for the same service in the same geographic area, alongside other credible information submitted by either party. Providers prevail by submitting evidence that the QPA understates the actual market value of the service: case complexity, training and experience of the provider, scope of services, market share dynamics, and prior contracted rates with the payer. The IDR entity selects one of the two proposed amounts in baseball-style arbitration. There is no compromise; one side wins each dispute.
Documentation that wins
Successful IDR submissions share common documentation patterns:
- Specific case complexity factors documented in the medical record (acuity, comorbidity, length of procedure) that distinguish this service from a median case.
- Provider qualifications including subspecialty training, years of experience, and any factors that justify above-median rates.
- Comparable rate evidence from other contracts, regional benchmarking sources, or published charge data.
- The proposed payment amount must be reasonable relative to the QPA. Providers asking for ten times the QPA almost always lose. Providers asking for 1.5 to 3 times the QPA, with documentation, often win.
Batching disputes
The rules allow providers to batch similar disputes together when they involve the same payer, the same service code, and the same patient encounter type, subject to specific limits. Batching reduces administrative cost per dispute meaningfully. The most efficient approach is to identify a recurring payer-service combination where underpayment is happening at scale, build a batched submission with documentation supporting the entire group, and run it through one IDR entity. A win on a batch sets a useful precedent for future negotiation with the same payer.
Where IDR is not available
IDR is not available for self-funded ERISA plans that opted out, for Medicare or Medicaid claims (those have their own appeals processes), for services that were not legitimately out-of-network, or for in-network rate disputes (those go through contract dispute resolution). Submitting an ineligible dispute wastes the IDR entity fee and counts against the provider’s submission record. CMS’s data analysis flags submissions where eligibility appears questionable, and the upcoming Gateway platform will include identity and eligibility verification at the front end. Practices should verify eligibility before initiating, not after.
The Gateway transition in late 2026
The new IDR Gateway, announced for late 2026 rollout, will replace the current single-use web forms with a secure centralized platform that supports multi-dispute management, dashboards, identity verification, and U.S.-only access. Practices that have built workflows around the existing forms should plan a brief transition period when the Gateway launches. The underlying rules of IDR are not changing; the user interface and audit trail are.
How MHB helps out-of-network practices use IDR
For practices with out-of-network revenue at risk and limited internal capacity to run IDR, our team handles end-to-end A/R recovery including NSA IDR submission, with negotiation tracking, batched-dispute preparation, documentation builds, and Gateway-ready workflow. The work runs alongside the practice’s existing claims operation.
The bottom line
IDR is one of the few revenue tools where the federal data shows providers winning the large majority of disputes when they engage. The barrier is workflow: identifying eligible disputes, preparing the documentation, and meeting the timing windows. Practices that build the workflow recover meaningful out-of-network revenue. Practices that do not are subsidizing payers.
