Independent Dispute Resolution Outcomes for Planned Procedures under the No Surprises Act

October 2026
Full study

Providers won nearly 90% of disputes for planned surgical and endoscopic procedures that went through the Independent Dispute Resolution (IDR) process, with provider payments (awards) far exceeding benchmarks that reflect in-network commercial rates and Medicare rates.

The No Surprises Act (NSA) protects patients from unexpected medical bills and established a process to resolve payment disputes between plans and providers for certain out-of-network services. This study analyzed awards for 7,304 disputed claim lines involving planned procedures, including spine surgery, plastic surgery, and endoscopic services that went through the IDR process.

This study, published in Health Affairs Scholar, found IDR awards were extreme, averaging more than 50 times benchmarks reflecting in-network commercial rates. Provider win rates did not change with increasing provider or insurer offers. Policy changes are needed so that the NSA does not contribute to rising healthcare costs, particularly for planned out-of-network care that should not be a “surprise” for patients.
