The Independent Dispute Resolution (IDR) process, established by the No Surprises Act to prevent unexpected medical bills, has experienced a massive surge in volume and cost. While regulators originally projected approximately 17,000 annual disputes, data from 2025 shows the system generated roughly 2.5 million cases.

Providers have maintained a high success rate in these arbitrations, winning approximately 85% to 88% of cases. This trend has transformed the process into a multibillion-dollar industry, with reports indicating nearly $15 billion was paid out through the IDR system in 2025, while arbitrators collected $1.3 billion in fees during that same year.

Critics express concern that the winner-takes-all arbitration model tilts heavily toward providers and may drive up overall healthcare costs and consumer premiums.
