The federal IDR record, in one place.
Published win rates and award multiples, with the source and reporting period on every figure.
This benchmark aggregates the published federal IDR record into one citable page. Every figure below is drawn from CMS Public Use Files and independent analyses by Georgetown CHIR, the Congressional Research Service, and others, with the source and reporting period noted. These are aggregate federal figures, not a prediction about any one claim, and they move as new public use files publish. These are aggregate federal figures from CMS Public Use Files and independent analyses. They are not Sydra outcomes. They describe the federal IDR record across all disputes and they update as new public use files publish.
Provider win rate.
Providers win the large majority of properly filed federal IDR disputes. Analysis of CMS figures found providers prevailing in about 88 percent of resolved disputes through the first half of 2025, and separate review put 2024 determinations at about 85 percent in the provider's favor.
- About 88 percent provider win rate. Source: CMS Federal IDR Public Use Files and Georgetown University CHIR analysis. As of H1 2025.
- About 85 percent of 2024 determinations decided for the provider. Source: Congressional Research Service R48738. As of 2024.
Awards versus the qualifying payment amount.
The qualifying payment amount, or QPA, is the plan's median contracted rate and its anchor in a dispute. In practice the prevailing offer beats the QPA in the large majority of determinations.
- In about 88 percent of determinations, the prevailing offer beat the qualifying payment amount. Source: CMS Federal IDR Public Use Files. As of 2024 to 2025.
- Independent review found the prevailing offer exceeded the QPA in about 87 percent of awards, with a median award several times the in network rate. Source: American College of Radiology analysis of CMS data. As of January 2026.
Award multiples by specialty.
The averages hide the real story, which is how far surgical awards run above the QPA compared with the high volume specialties. Surgery and neurology recover the widest multiples in the dataset.

- Radiology disputes award around 559 to 594 percent of the QPA. Source: Georgetown CHIR and CMS PUF. As of 2024 to 2025.
- Emergency disputes award far smaller multiples than surgery, which is why aggregators crowd that lane and surgery stays open. Source: Georgetown CHIR and CMS PUF. As of H1 2024.
Dispute volume and who files.
Volume is dominated by a handful of high frequency filers, while the highest value specialties file rarely. That gap is why the surgical lane stays open.
- About 4.8 million disputes were filed through the end of 2025, against the roughly 17,000 per year Congress expected. Source: Georgetown CHIR and CMS bimonthly updates. As of December 2025.
- Surgery and neurology together were only about 9 percent of resolved cases, yet they win the largest multiples. Source: Georgetown CHIR. As of 2024.
- An estimated 10 percent of eligible claims ever reach IDR arbitration. Source: ACEP analysis of CMS data.
Plan routing context.
How a claim routes shapes the benchmark that applies. Self funded plans are the dominant path to the federal process.
- About 65 percent of covered workers are in self funded plans, which route to federal IDR regardless of state. Source: Peterson KFF Health System Tracker. 2021 baseline.
- About 22 states have a specified state law that can govern fully insured disputes instead of the federal process. Source: Commonwealth Fund. As of 2024 to 2025.

Frequently asked
What is the provider win rate in federal IDR?
Analysis of CMS data found providers prevailing in about 88 percent of resolved federal IDR disputes through the first half of 2025, and about 85 percent of 2024 determinations were decided for the provider. Win rate reflects the pattern across many determinations and is not a guarantee on any single claim.
How much higher than the QPA are IDR awards?
The prevailing offer beat the qualifying payment amount in roughly 87 to 88 percent of determinations. Surgical disputes win the largest multiples versus the QPA, far above emergency disputes.
How many IDR disputes have been filed?
About 4.8 million disputes were filed through the end of 2025, against the roughly 17,000 per year Congress originally expected. Surgery and neurology were only about 9 percent of resolved cases despite winning the largest multiples.
Are these Sydra performance figures?
No. These are aggregate federal figures from CMS Public Use Files and independent analyses, not Sydra outcomes. They describe the federal IDR record across all disputes and update as new public use files publish.
