What certified IDR entities do
CMS explains that when a provider or facility and a health plan cannot agree on the payment amount for an eligible out-of-network service covered by the No Surprises Act, a certified IDR entity can be selected to make the payment determination.
The federal roster applies to disputes involving providers, facilities, providers of air ambulance services, group health plans, health insurance issuers, and Federal Employees Health Benefits Program carriers when the federal process governs. CMS states that every listed entity is certified to operate in each state where the federal IDR process applies.
