Why does an EOB generated from an ERA show the status Unprocessed even though the associated claims are already Paid or Denied?

This is the expected behavior of the system.

ERAs received from Availity and AI Posting are two independent processes.

When Amexzone receives an ERA file from Availity, the system automatically converts it into an EOB and updates the corresponding claims based on the information received, setting their status to Paid or Denied as appropriate.

The Unprocessed status displayed on the EOB refers only to the AI Posting workflow. AI Posting is a separate feature used to process payment documents that already exist in the system. During this process, the document moves from Unprocessed to Processing, and once the results are available, the biller can review them before accepting or correcting the posting.

For this reason, it is completely normal for an EOB generated automatically from an ERA to remain in the Unprocessed status even though the associated claims have already been updated to Paid or Denied. This status does not indicate that the ERA was not processed; it only indicates that the document has not gone through the AI Posting workflow.
