If a health plan underpaid an out-of-network claim, Independent Dispute Resolution (IDR) is the federal process that lets you fight for fair payment. Here's a plain-language guide for providers—what IDR is, which claims qualify, and how the process works.
Independent Dispute Resolution (IDR) is a federal arbitration process created by the No Surprises Act (in effect since January 1, 2022) to settle payment disagreements between out-of-network providers and health plans. When a plan's payment on a qualifying claim is too low, the provider can escalate the dispute to a certified, neutral arbitrator—called an IDR entity—who reviews both sides and decides the payment.
It's often described as "baseball-style" arbitration: each side submits a single payment offer with supporting evidence, and the arbitrator must pick one of the two offers—not split the difference. That structure rewards a well-prepared, well-documented case.
IDR is meant for the situations the No Surprises Act protects patients from—so it generally applies to:
These are the classic "surprise bill" scenarios—where a patient couldn't reasonably choose an in-network provider, and the provider ends up underpaid by the plan.
After the plan's initial payment or denial, a 30-business-day open negotiation period begins to try to resolve the gap directly.
If it's still unresolved, either party has just 4 business days after that period ends to formally start IDR. Miss it and you lose the right to dispute that claim.
The two sides choose a certified IDR entity. Each submits a payment offer plus supporting information—including the qualifying payment amount (QPA) and other permitted factors.
The arbitrator picks one offer. The decision is binding, and the losing party pays the IDR entity's fee—so a strong offer matters.
No. A core purpose of the No Surprises Act is to take patients out of the middle of these disputes. IDR is strictly between the provider and the health plan. The patient only owes their normal in-network cost-sharing—the rest is settled between the two businesses.
For practices with meaningful out-of-network volume, IDR is often the difference between accepting a lowball payment and recovering fair reimbursement. But it comes with a catch: the deadlines are strict and unforgiving, and each dispute needs a properly built, evidence-backed offer to win. That's why many providers work with a dedicated IDR partner rather than manage the process in-house.
How long do I have to file?
A 30-business-day open negotiation period, then only 4 business days to initiate IDR. Missing that window forfeits the claim.
Is the decision final?
Yes—the arbitrator's choice is binding, and the losing side pays the IDR entity fee.
Do I have to involve the patient?
No. IDR is provider-vs-plan only.
