After an agent uploads ACA Data Matching Issue (DMI) documents in MyMFG on behalf of a client, the status in MyMFG will continue to show as pending. This is expected. The pending status does not mean the documents were not received — it means CMS has not yet reviewed and approved them.

Once DMI documents are uploaded in MyMFG, the review is handled entirely by CMS (Centers for Medicare and Medicaid Services). MyMFG reflects whatever status CMS has assigned to the case. There is nothing further an agent can do inside MyMFG to move the review forward — the pending status will remain until CMS completes their review.

CMS turnaround time for DMI document review varies and cannot be predicted. In the experience of Messer Producer Support, CMS tends to approve uploaded documents closer to the document submission due date rather than immediately after upload. Agents should not interpret a pending status as an indication that documents were rejected or lost.

For reference, the general CMS review windows for common DMI types are:

These are the outer limits of the review window, not guaranteed approval timelines. CMS may approve documents at any point within that window.

There is no action available inside MyMFG while a DMI is pending after documents have been uploaded. If an agent or client needs confirmation that CMS received the uploaded documents, they can call the Marketplace Call Center Agent/Broker Line at 1-855-788-6275. Have the client's National Producer Number (NPN) ready to access the agent/broker line.

Agents should advise clients that their coverage may not be effectuated until the DMI is resolved by CMS, even if documents have been submitted.
