Which claims can use federal IDR?
Federal IDR determines payment amounts for certain out-of-network items and services. Eligibility depends on the service, coverage, and applicable jurisdiction; an underpayment alone does not establish eligibility.
CMS: About independent dispute resolutionDoes IDR overturn a medical-necessity or coverage denial?
A denial of payment is not the same as a denial of coverage. Medical-necessity and other adverse benefit determinations may require an internal appeal or external review. Establish coverage and federal IDR eligibility before treating a claim as a payment dispute.
CMS: External review of coverage decisionsWhat should a practice prepare?
Gather the EOB, claim identifiers, service dates and locations, service and place-of-service codes, the other party’s contact details, and the required eligibility attestation. Preserve the negotiation record and supporting offer evidence.
CMS: Information to prepareDoes federal IDR or state law apply?
The answer depends on the plan, service, and applicable state law or All-Payer Model Agreement. Use the CMS applicability chart and relevant plan information; location alone is not a complete jurisdiction test.
CMS: Federal IDR applicability chartWhat fees should a practice budget for?
Distinguish the federal administrative fee from the certified IDR entity’s fee. The May 2026 operations final rule announces a $15 administrative fee per party per dispute. Check applicability dates and the selected entity’s fee schedule before filing; a historic fee quoted in an article may not apply to a new dispute.
CMS: 2026 operations final ruleWhen can a party initiate federal IDR?
CMS describes a 30-business-day open negotiation period followed by a four-business-day initiation window, subject to extensions. Check current notices and transition guidance before calculating a case deadline.
