Am I Eligible for Federal IDR? The 8 Requirements, Explained
To be eligible for the federal Independent Dispute Resolution (IDR) process, an out-of-network payment dispute must satisfy all eight statutory criteria. Not most of them. All of them. The criteria come from 42 U.S.C. § 300gg-111(c)(1) and 45 C.F.R. § 149.510. If even one fails, the dispute is ineligible and the federal IDR entity will dismiss it. This guide lists the full checklist, the timing rules the portal actually enforces, and the conditions that most often disqualify a claim.
What is the federal IDR process?
The No Surprises Act created a baseball-style arbitration process for certain out-of-network claims. After payment, an out-of-network provider, facility, or air-ambulance service that disagrees with a health plan’s payment can take the dispute to a neutral, certified IDR entity (IDRE). Each side submits a final payment offer, and the IDRE selects one.
The process applies only to specific situations. If your claim does not fit the scope below, IDR is not the right channel.
What are the eight eligibility criteria?
A dispute is eligible only if every one of these is true:
- In scope. The services are out-of-network emergency services, out-of-network non-emergency services delivered at an in-network facility, or air-ambulance services covered by the No Surprises Act.
- NSA-covered plan. The patient has coverage through a group health plan or individual health insurance subject to the NSA, not Medicare, Medicaid, CHIP, or TRICARE.
- No specified state law applies. A state surprise-billing law that governs the dispute removes it from the federal process.
- The service was covered. Payment was not denied for a non-coverage reason; the plan covered the item or service.
- No waiver. The patient did not waive their balance-billing protections.
- Open negotiation completed. The provider initiated and exhausted the 30-business-day open negotiation period.
- Filed within the window. The provider initiated IDR within four business days after open negotiation ended.
- Cooling-off respected. There was no prior IDR determination on the same services against the same payer in the previous 90 calendar days.
This eight-point enumeration tracks the statute and regulation directly. Treat it as a pre-filing gate: confirm all eight before you initiate, because a dispute dismissed as ineligible still costs you the non-refundable administrative fee.
How long do I have to start IDR?
Timing is where eligible disputes most often die on a technicality. Two clocks matter:
- The 30-business-day open negotiation. You cannot file IDR until you have completed open negotiation with the plan. The federal portal enforces this by checking the open-negotiation start date you enter, if it is not at least 31 days before your submission date, the portal blocks you from proceeding.
- The four-business-day initiation window. Once open negotiation ends, you have four business days to initiate IDR. File outside that window and the portal requires you to supply an extension reason and supporting documentation.
What does IDR cost?
Two fees apply to each dispute:
- A non-refundable administrative fee, paid by both parties at initiation. It is not returned even if the IDRE dismisses the dispute as ineligible or the initiating party withdraws.
- A certified-IDRE fee, set by the specific entity and varying by a wide range depending on the IDRE and whether the dispute is batched.
The party whose offer the IDRE selects has its IDRE fee refunded; the non-prevailing party pays both. Because the administrative fee is sunk regardless of outcome, filing ineligible disputes is pure loss, another reason the eight-criterion gate matters.
What most often makes a claim ineligible?
In practice, the leading disqualifier is criterion 3, a specified state law applies. Payers flag this aggressively and at multiple points: on the Explanation of Payment (using plan-specific adjustment codes), in response to an open-negotiation request, and again after IDR initiation. A best-in-class intake process captures all three signals and routes every claim through a pre-IDR eligibility check rather than discovering the problem after paying the administrative fee.
The other recurring blockers are mechanical: missing the four-business-day filing window, services denied for a non-coverage reason (criterion 4), and tripping the 90-day cooling-off period on the same services against the same payer.
How Equavis helps
Equavis Health works on the provider side: confirming eligibility against all eight criteria before a dollar of fees is spent, managing the open-negotiation and initiation clocks, assembling the QPA and supporting documentation, and selecting and filing through the federal portal. The goal is to keep ineligible disputes out and to present eligible ones in their strongest defensible form.

Frequently asked questions
What makes a claim eligible for federal IDR?
A claim is eligible for the federal Independent Dispute Resolution (IDR) process only if it satisfies all eight statutory criteria at once: the service is within No Surprises Act scope; the patient has NSA-covered group or individual coverage; no specified state law applies; the service was covered (not denied); the patient did not waive balance-billing protections; the provider completed the 30-business-day open negotiation; the provider initiated IDR within four business days after open negotiation ended; and no IDR determination was made on the same services against the same payer in the prior 90 days.
How long do I have to start the IDR process?
You must first complete a 30-business-day open negotiation period, then initiate IDR within four business days after that period ends. The federal IDR portal enforces this: it blocks submission if the open-negotiation start date you enter is not at least 31 days before your submission date, and it requires an extension reason with documentation if you file outside the four-business-day window.
What does it cost to file an IDR dispute?
Two fees apply. Each party pays a non-refundable administrative fee (set by the Departments and reset periodically) that is not returned even if the dispute is found ineligible or withdrawn. Each party also pays the certified IDRE's fee, which varies by entity. The party whose offer the IDRE selects has its IDRE fee refunded; the non-prevailing party bears both fees. Confirm the current administrative-fee amount before filing, as it is revised over time.
What most often makes a claim ineligible?
The most common blocker is a specified state law applying to the dispute, which removes it from the federal process. Payers commonly flag this on the Explanation of Payment, during open negotiation, and again after IDR initiation. Other frequent blockers are missing the four-business-day filing window, services that were denied for non-coverage reasons, and the 90-day cooling-off period on the same services against the same payer.
