If the Claims on Hold option was selected in new account setup for training purposes, the claims within that status can be released with Bulk Rebill.
First, use the Advanced Claim Management Tool to sort claims you would like to bulk rebill and remove the hold.
Next, click the Bulk Rebill button, leave the default transaction code "-Select additional transactions", check the box below it "Take these claims off hold" and click "OK".
Lastly, when you see the popup below, click| "OK".
The claims that were Bulk Rebilled will now appear in Awaiting Claim File Creation status.
