Search for claim# and check if there is an XA ID given after the claim #.

"Queued" or "pending" means the claim has been sent to XA and is being processed. If blank, the claim has not been pushed to XA at all yet.

In the Claims grid (results of searching for claim #), click "display mode" in the top left and select batch mode. Click "pick action" and select "XA claim export." If there is an issue, the left-most column will show a red sign instead of a checkbox. Hover over the red sign to reveal the reason for the failure.
