How do I set up a follow up claim reminder within ClaimWizard?

In a claim, click the "Update Claim" button and select the "Action Items" tab.

This will let you add action items to a single claim as needed. You can also do this directly from the action items tab in the claim. The update claim option is also available anywhere in the system where you see a blue up arrow or blue update button (e.g. open claims workbench, action item, workbench, quick view sidebar.)
