On systems configured for overlapping (non-unique) MPIs, OnBase uses both the MPI value and the MPI assigning authority to uniquely identify patients.
If your system is configured for overlapping MPIs, select the Use Assigning Authority option. When this option is selected, the Unlink Master Patient Index Number action will use both the MPI value and the assigning authority value to identify the MPI to unlink.
-
If the assigning authority value is populated on the document or WorkView object when this action is executed, then the action will look for a matching MPI that has the specified assigning authority.
-
If the assigning authority is not populated, the action will look for a matching MPI that has a blank assigning authority.
Ensure this option is selected if your system allows overlapping MPIs. Otherwise, the Unlink Master Patient Index Number action will unlink all MPIs that match the MPI value on the document or WorkView object. The assigning authority value will be ignored.
