Solve DMIs or Your Clients May Lose Coverage

Last updated: August 1, 2025

During open enrollment, you may have encountered Data Matching Issues (DMIs) in your clients’ applications. Failing to address DMIs within 90 to 95 days may result in a loss of premium tax credits, cost-sharing reductions and in some cases, coverage. 

DMIs occur when:

• Information is incomplete or missing.
• The client's application doesn’t match data from credible sources like IRS databases.

Where to Find DMIs:

On your Agent Assisted On-Exchange Enrollment Solution , powered by HealthSherpa, account:

• The confirmation page you received after enrolling a client in a plan will flag any DMIs with the client’s next steps.
• This information will automatically populate in your Clients tab in the "Documents" column. Click "View" to see the details.

Through the Marketplace:

• Review the eligibility determination notice from the Marketplace to see if any DMIs appear under the “Next Steps” section.
• If your client has a DMI, you will see the message: "Important: You must submit documents." 

Fixing DMIs:

Check the client's application for typos or errors:

• If you find any, resubmit the application to see if this resolves the DMI.
• If no errors were found or resubmitting doesn’t work, you or your client will need to submit documents directly to your Agent Dashboard specific to the issue. You can also call Technical Support for help, using the phone number listed under Agent-Assisted On-Exchange Enrollment:
