On June 4, 2026, the Departments of Labor, Health and Human Services, and the Treasury, along with the Office of Personnel Management, published a final rule amending the operation of the Federal Independent Dispute Resolution process under the No Surprises Act (91 FR 33949, the Federal IDR Operations final rule). This page summarizes what the rule changes and states, where the text on file gives a specific date, when each change takes effect. It gives no advice on offers, amounts, or how any party should respond to a pending dispute.
The final rule itself states: "These final rules are effective on August 3, 2026" (91 FR 33949 at 33949, DATES section). That is the effective date of the rule as a regulatory instrument. It is a separate question, addressed provision by provision below, from when any given substantive change actually becomes applicable to a live dispute -- the rule expressly directs readers to a dedicated section for applicability dates (91 FR 33949 at 33949, "See section II.H. of these final rules for information on the applicability dates").
The definition of batched qualified IDR items and services (45 CFR 149.510(a)(2)(i)) is applicable for disputes with open negotiation periods beginning 90 days after the effective date of the final rules (91 FR 33949, applicability-dates discussion, "Definition of Batched Qualified Items and Services"). Given an August 3, 2026 effective date, the rule text states this applicability window in relative terms ("90 days after the effective day of these final rules") rather than naming a calendar date directly; this page does not convert that relative figure into a specific calendar date, since the primary text itself states it relatively.
Certain other provisions -- including modifications to the authority to continue negotiations or withdraw (45 CFR 149.510(c)(3)(i) and (c)(3)(ii)(C) and (D)) and the extension of time periods for extenuating circumstances (45 CFR 149.510(g)) -- apply 90 days after the effective date of the final rules as well (91 FR 33949, applicability-dates discussion).
A separate, larger group of provisions -- covering selection of the certified IDR entity and the Federal IDR process eligibility review (45 CFR 149.510(c)(1) and (c)(2)), certain withdrawal provisions (45 CFR 149.510(c)(3)(ii)(A) and (B)), the batching provisions discussed elsewhere on this site (45 CFR 149.510(c)(4)), the deadline for submission of offers and payment determination and notification (45 CFR 149.510(c)(5)(i) and (ii)), and the suspension of certain subsequent IDR requests (45 CFR 149.510(c)(5)(vii)(B) and (C)) -- apply to disputes with open negotiation periods beginning 90 days after the Departments issue guidance announcing that the portal functionality supporting these provisions has become available (91 FR 33949, applicability-dates discussion). The preamble states the Departments anticipate releasing that guidance on a rolling basis, beginning in Summer 2026, but the final rule text reviewed for this page does not itself name a fixed calendar date on which that guidance, or each gated provision, becomes applicable (91 FR 33949, applicability-dates discussion). Until that guidance issues, this page treats the 50-item batching cap and the associated eligibility-window changes as not yet applicable to any dispute, consistent with how Our own engine documents this same gate.
The $15-per-party-per-dispute administrative fee amount (45 CFR 149.510(d)(2)(ii)) applies to disputes initiated on or after June 11, 2026, which the rule describes as 5 business days from the publication date of these final rules (91 FR 33949, applicability-dates discussion, administrative and certified IDR entity fee collection).
This page was prepared against the primary rule text on file, searched specifically for the terms "Gateway" and plan-level registration provisions. Neither was found. There is no reference to a "Gateway" mechanism in the primary text reviewed for this page, and no separate effective or applicability date specific to plan-level registration beyond the general plan and issuer registration requirements discussed elsewhere in the rule. That is a statement about what the rule text on file contains, not a statement that no such mechanism exists. A reader looking for Gateway-specific timing should consult current CMS guidance directly rather than rely on this page.
The other three guides on this site -- on batching, on entity selection and objection, and on open negotiation and cooling off -- describe what the June 2026 rule changes substantively. This page is limited to when those changes take effect. Because several of the most consequential provisions (batching, selection, and eligibility review) are gated on guidance that had not issued as of this page's preparation, a reader evaluating a specific dispute should confirm current applicability against CMS's published guidance rather than assuming every provision described on this site is already in force.
Trilatic is preparing an application to become a certified Federal IDR entity and is not accepting disputes. This guide states no outcome and gives no advice on offers or amounts.
