IDR 2024: What the Congressional Research Service Data Means for Plan Sponsors

The Independent Dispute Resolution report covering 2024 from the Congressional Research Service echoes what plan sponsors have sensed for months. A process that was supposed to bring order to out of network payment disputes is now crowded, driven by provider actions and far less predictable. For self-insured employers, the takeaway is straightforward: Do not expect the IDR process to control costs or shield your plan. Be prepared to defend it.

Here is what the complete 2024 data shows and what it means for your health plan.

The Volume Problem: IDR Is Flooded

In 2024, more than 1.46 million IDR disputes were initiated. That is more than double the number from 2023. Instead of decreasing friction in the market, the IDR system has become the new battlefield for payment negotiations.

Most of these cases involve claims employers know well. OON emergency and nonemergency services made up 97 percent of all filings, with the rest tied to air ambulance. This surge is not coming from consumers. It is almost entirely driven by providers. In 2024, over 99 percent of all disputes were provider initiated.

Providers Are Winning and Winning Big

Providers are not just active participants in the IDR process. They are overwhelmingly winning. In 2024 they prevailed in about 85 percent of all payment determinations and a similar share of selected offers came in above the Qualifying Payment Amount (QPA). The gap between the QPA and the amounts providers ultimately secure is no longer a narrow difference. It is widening at a pace that should concern every plan sponsor.

The specialty level data makes this clear. In surgery, the median prevailing offer rose from about three times the QPA in early 2023 to thirteen times the QPA by the end of 2024. Neurology and neuromuscular procedures show an even steeper climb, moving from roughly three times the QPA to seventeen times within the same period. When payments drift this far from the statutory benchmark, plan liabilities become unpredictable. No model can comfortably absorb swings of this size and the financial risk to plans becomes impossible to ignore.

Where the Pressure Builds and Why Timing Still Fails Plans

IDR activity is not spread evenly across the country. Texas alone generated 500,020 disputes in 2024, a volume greater than the next six states combined. A small group of states accounted for more than seventy percent of all emergency and nonemergency filings.

For employers that operate in multiple states, this concentration creates uneven exposure. Some markets face far more aggressive provider tactics and far higher reimbursement demands, which can push plan costs well beyond expectations.

At the same time, the process continues to fall behind. IDR entities resolved more than four times as many disputes as they did in 2023, yet payment determinations still regularly missed statutory deadlines. Heavy filing volume, complex claims and near universal provider participation keep the system under strain. When decisions lag, plans lose the ability to forecast costs or close out claims with confidence and that uncertainty becomes its own form of financial risk.

What This Means for Employers and Self-Insured Plans

The CRS data confirms several realities for plan sponsors.

IDR is not functioning as a balanced negotiation tool.
Provider initiated filings, especially from large or private equity backed groups, will continue to drive up costs.
The QPA is no longer a reliable predictor of liability.
Plans without strong reimbursement logic, dispute support and enforcement strategies are at risk of paying inflated amounts.
Administrative delays can interrupt budgeting, reserving and stop-loss coordination.

In short, the risk is rising. Plans need partners who understand how to navigate the IDR environment and challenge unreasonable demands.

How aequum Protects Plans in an Overloaded IDR System

aequum’s experience in defending plans and participants is built for exactly this moment. aequum’s team supports self-insured plans by:

Managing and defending OON disputes to prevent inflated provider demands.
Guiding plans through the IDR process when filings escalate.
Preserving all plan rights and documenting positions that protect against adverse determinations.
Challenging improper or opportunistic claims, including those driven by private equity backed groups and third party representatives.
Analyzing trends and exposure so employers understand where their plan is most vulnerable.
Supporting reimbursement strategies that reduce reliance on volatile market pricing.

With IDR filings climbing and provider behavior becoming more aggressive, plan sponsors cannot treat these disputes as routine. They have become a core cost driver.

The Takeaway: In This IDR Environment, Plans Need a Strong Defense

The Congressional Research Service made it clear. The system designed to settle disputes is under pressure and shifting in ways that increase financial risk for employers. You cannot rely on statutory protections alone.
