The Centers for Medicare & Medicaid Services has set the dates for the next phase of the Federal Independent Dispute Resolution (IDR) Gateway. Beginning Nov. 13, 2026, parties and their representatives will be able to initiate disputes, respond to cases, select a certified IDR entity, and submit offers directly within the Gateway. The current web forms outside the Gateway will remain available for a transition period, then sunset after Jan. 15, 2027.
Here is what the upcoming IDR gateway transition means for the organizations that use the Federal IDR process, and what FHAS recommends doing now so the transition is a smooth one.
Two dates to put on the calendar
- Nov. 13, 2026 – Organizations with IDR Gateway accounts can submit the Notice of IDR Initiation, Notice of IDR Initiation Response, Notice of Certified IDR Entity Selection, and Notice of Offer web forms inside the Gateway. Gateway users also will be able to view reports and access dispute records, both for disputes started in the Gateway and for earlier disputes that have been mapped to their organization.
- Jan. 15, 2027 – The last day the web forms will be available outside the Gateway. After this date, the only form that remains outside the Gateway is the Notice of IDR Initiation – Resubmission.
In short, Nov. 13 is when parties can start working in the Gateway, and Jan. 16 is when they must.

Who needs a Gateway account
Any organization or individual that processes disputes, represents parties named in disputes, or submits IDR web forms needs to sign up for a Gateway account to use the new features. If your organization relies on a third-party administrator, billing company, or law firm to handle disputes, you do not need your own account, but the organization managing your disputes does. It is worth confirming now that whoever submits on your behalf has signed up.
A note on disputes that are not yours
Parties have had Gateway access since Sept. 15, and the Gateway matches disputes to an organization based on the contact information supplied to the Federal IDR portal. Occasionally that match will be wrong. The Gateway now allows parties to confirm or deny ownership of a dispute that has been assigned to it. CMS describes this as a security measure, not a new type of objection. Its purpose is to remove an organization from a dispute that does not belong to it, so that users in that organization are not viewing someone else’s case.
If your organization denies ownership, the certified IDR entity reviews the denial. The Gateway offers no option to upload documentation with a denial, so the certified IDR entity will generally look to the remittance to see whether it points to your organization or to another party, such as a third-party administrator. If the IDRE agrees with the denial, the dispute will no longer be visible to your organization in the Gateway. CMS has said it will provide further guidance on administrative fees in these situations.
Denying ownership is a tool for correcting misrouted disputes, so we encourage parties to check the remittance before using it. If a dispute before FHAS has reached you in error, our team is glad to help sort it out.
What this means for working with FHAS
Nothing changes in how you work with us. CMS has directed certified IDR entities to continue their current processes, including how they receive information and manage disputes. FHAS will continue to access dispute data and documents through the Federal IDR portal and the certified IDR entity APIs, and our team will continue to communicate with parties the same way we do today.
Four steps to take before Jan. 15
FHAS urges parties to use the two-month window between Nov. 13 and Jan. 15 and recommends that both initiating and non-initiating parties take these steps:
- Confirm you have a Gateway account, or that the organization submitting on your behalf does.
- Test the new functionality between Nov. 13 and Jan. 15, while the web forms are still available as a fallback.
- Make any internal process changes before Jan. 15, so the people who initiate and respond to disputes can get comfortable using the Gateway before it is required.
- Resolve any issues on your end with submitting solely within the Gateway before Jan. 15.
CMS has also updated the Federal IDR Portal User Guide, the Reports Tab User Guide, the Data Exchange Out-API Companion Guide, and the Field Reference Guide to reflect the change. All four are available on the Registration for Technical Assistance Portal (REGTAP).
CMS has said it will hold additional training sessions and publish further guidance for parties on using the Gateway, and the Federal IDR Team will provide ongoing updates as the Gateway is implemented. We will share those as they come. Questions about the Gateway itself can go to IDRGatewayHelp@cms.hhs.gov or 1-800-985-3059. Questions about a dispute before FHAS, or about how the transition affects your cases with us, or about all things IDR, can come to our team as always.
