With the unsubmitted_claims_search advanced setting, you can choose to display the Pending, Unsubmitted option in the Filter By dropdown list on the Claims List screen.
This setting requires True and False buttons.
By default, the unsubmitted_claims_search advanced setting is set to True, so Pending, Unsubmitted appears in the Filter By dropdown list on the Claims List screen.
Changing the default
To change the default, navigate to Settings > Advanced and search for unsubmitted_claims_search. Change the setting to False, so Pending, Unsubmitted will be hidden from the Filter By dropdown list.
