What a certified IDR entity does
A certified IDR entity, often shortened to IDRE, is a federally certified organization authorized to decide payment disputes in the federal IDR process. If the provider or facility and the plan cannot resolve the amount through open negotiation, the certified IDR entity reviews the parties' final offers and supporting information.
The IDRE does not create its own compromise number. In federal IDR, it selects one offer. That puts real pressure on the offer and the supporting record.
How IDRE selection works
When a party initiates federal IDR, it identifies a preferred certified IDR entity. The non-initiating party can agree or object and propose an alternative within the required timeframe. If the parties do not agree, the federal departments randomly select a certified IDR entity under the process timeline.
The selected entity must attest that it has no conflict of interest and determine whether the federal IDR process applies. Eligibility review is one reason disputes can slow down or be closed before a payment determination.
- Initiating party proposes an IDRE in the Notice of IDR Initiation
- Non-initiating party can agree or object
- If the parties fail to agree, the departments select an IDRE
- The IDRE attests no conflict and reviews applicability
2026 certified IDR entity fees
CMS publishes the list of certified organizations and their fixed fees. As of the CMS list reviewed for 2026, single-determination fees range from $425 to $800 depending on the certified IDR entity. Batched fees and tiered fees vary by entity as well.
Fees matter most when dispute values are low or when batching strategy is unclear. A page-level benchmark may show that arbitration outcomes are attractive on a code, but the economics still need to account for administrative fees, IDRE fees, staff time, and the probability of eligibility objections.
What IDREs can consider
The certified IDR entity must consider the QPA and may consider other allowable statutory factors, including training and experience, quality and outcomes measurements, market share, patient acuity, service complexity, teaching status, case mix, scope of services, and good-faith contracting efforts where applicable.
Certain factors are prohibited, including billed charges, usual-and-customary charges, and public payer rates. Submissions should be built around allowable factors, not generic dissatisfaction with the initial payment.
How to use IDRE data
Starting with more recent CMS public use files, certified IDR entity names are available at the dispute-line level. That creates a new layer of analysis: outcomes can be compared by payer, specialty, state, service code, and the entity deciding the dispute.
IDRE-level data should be interpreted carefully because case mix matters. Still, it can help teams understand fee economics, throughput, and how outcome patterns differ across certified entities.

No. Fees vary by entity and by single versus batched determinations. CMS publishes the current fee list.
