Use the CMS IDR Gateway to manage dispute submissions and monitor dispute status after its launch in the latter half of 2026

Steps

1. 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.
2. 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.
3. 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.
4. Review notifications sent through the Gateway when the IDR entity issues a determination, including the selected offer and any applicable reasoning.
5. 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.
6. Export dispute history reports from the Gateway for internal audit trails and to identify patterns in IDR outcomes that may inform future negotiation strategy.
