Published Date: 8/28/2026
Rule
Summary
This document corrects typographical errors and omissions in the final rule that appeared in the June 4, 2026, Federal Register titled "Federal Independent Dispute Resolution Operations" (referred to hereafter as the "IDR final rule"). The effective date of the IDR final rule was August 3, 2026.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 2 costs, 1 mixed.
IDR decisions are final and binding
If you are a plan, issuer, provider, facility, or air ambulance service involved in a Federal Independent Dispute Resolution (IDR) case, a certified IDR entity's decision is binding on the parties unless there is fraud or intentional misrepresentation of material facts. Those decisions are not subject to judicial review except in cases described in any of paragraphs (1) through (4) of section 10(a) of title 9, United States Code.
Strict IDR negotiation and deadline schedule
The rule requires a 30-business-day open negotiation period that starts when a provider receives an initial payment or denial; the responding party must reply no later than the 15th business day of that period. If parties do not agree, either party may initiate IDR during a 4-business-day window after the negotiation ends, and the non-initiating party must file a response within 3 business days of IDR initiation; certified IDR entity selection deadlines operate on 3-business-day windows.
Notices must include QPA and remittance details
Open negotiation notices, IDR initiation notices, and responses must include detailed information such as the initial payment amount (including $0 if denied), the qualifying payment amount (QPA) if available, copies of any remittance advice, provider and plan contact details and identifiers (NPI, and TIN for providers when initiating), and other specified claim details. These documentation requirements support the Federal IDR process and must be submitted through the Federal IDR portal using standard forms.
'Downcode' defined for payment calculations
The rule adds a definition of 'Downcode' in the qualifying payment amount methodology: a plan or issuer alters a service code or modifier (including adding or removing a modifier) to one associated with a lower qualifying payment amount than the code/modifier billed by the provider, facility, or provider of air ambulance services.
