Independent Dispute Resolution (IDR)

How It Works

The Independent Dispute Resolution (IDR) process is the backstop mechanism in the No Surprises Act for resolving payment disputes between health plans and out-of-network providers on claims subject to the law's balance-billing protections. When a plan and provider cannot agree on payment through a mandatory 30-day open negotiation period, either party can initiate IDR by submitting a request through the federal portal administered by certified IDR entities (private arbitration firms approved by CMS). The process uses baseball-style arbitration: each party submits a single offer amount, and the IDR entity must choose one offer in full, with no splitting. Arbitrators weigh primary and secondary factors including the Qualifying Payment Amount (QPA, generally the median contracted in-network rate for the service in the geographic area), the provider's market share, the provider's training and experience, acuity of the patient, and previous contracting history between the parties. The IDR entity's decision is final and binding with no appeal to a court except for fraud or procedural error. Launch was chaotic. In 2022 HHS projected about 17,000 disputes for the first full year; actual volume exceeded 290,000, overwhelming the system. Volume continued to grow in 2023 (over 650,000 disputes) and remained elevated in 2024-2025. Providers have won a majority of IDR determinations, earning payment amounts often 200-500% of the QPA, a result that has driven lawsuits by insurers and hospital lobby groups (notably the Texas Medical Association v. HHS cases that overturned portions of the original QPA-weighting rule). Participation fees were raised multiple times (to $115 per party per claim in 2024) and batching rules tightened to reduce frivolous or abusive filings.
