Register your organization in the CMS IDR Gateway, completing the identity verification process required for all US-based users before the system grants dispute management access.
Log in to the Gateway dashboard to initiate a new dispute by entering the claim details, the failed open negotiation documentation, and your offer amount.
Use the dispute dashboard to track the dispute through its phases — submission, entity assignment, offer submission, determination — and respond to any information requests from the certified IDR entity within the displayed deadlines.
Review notifications sent through the Gateway when the IDR entity issues a determination, including the selected offer and any applicable reasoning.
If the determination is in your favor, use the Gateway records to demand payment from the payer within the required timeframe; if adverse, record the determined amount and close the claim.
Export dispute history reports from the Gateway for internal audit trails and to identify patterns in IDR outcomes that may inform future negotiation strategy.
Known gotchas
The IDR Gateway requires US-based access; international VPN exit nodes or proxy services will be blocked by the identity verification layer.
The Gateway replaces earlier single-use web forms beginning in the latter half of 2026; disputes initiated before Gateway launch through the legacy forms continue under the legacy process and should not be re-submitted through the Gateway.
Dispute dashboards are organization-scoped — individual user accounts must be explicitly associated with the correct organization in the Gateway before they can view or act on disputes.
