Provider IDR FAQ
Answers for medical practices about federal IDR eligibility, open negotiation, filing windows, state routing, evidence, and payment disputes.
FAQ
Federal IDR generally applies to qualified out-of-network emergency services, certain non-emergency services furnished by out-of-network providers during a patient visit to an in-network hospital, hospital outpatient department, critical access hospital, or ambulatory surgical center, and out-of-network air ambulance services. The plan, state law, service facts, and timing still need review.
No. Coverage denials, in-network contract disputes, ground ambulance claims, most scheduled care at out-of-network facilities, non-commercial coverage, and services outside the protected No Surprises Act categories generally require a different recovery path.
The required open negotiation period lasts 30 business days after valid initiation. Keep the notice, delivery evidence, payer response, and the exact start and end dates together in the matter file.
If open negotiation ends without agreement, federal IDR generally must be initiated during the four-business-day period beginning on the business day after open negotiation closes. Department-granted extensions or other official relief can change a specific deadline.
No. Routing depends on the claim and facility state, plan type and funding status, payer product, service category, dates, and any applicable state surprise-billing law. Many self-funded ERISA matters use federal IDR, while some fully insured claims follow a state process.
Start with the claim form, EOB or remittance, initial payment or denial notice, plan and payer information, facility and network status, dates of service, clinical documentation, correspondence, and proof of any open negotiation notice.
