OnBase keeps track of previous MPIs, MRNs, and Chart IDs that have been removed through a merge or rename process. This feature allows users of the Medical Records Unity Client and OnBase Patient Window to retrieve charts or records using previous MRNs, MPIs, or Chart IDs.
If you need to reuse previous patient identifiers for new patients, you can use OnBase Workflow to remove a previous MPI or MRN from the history of an existing MPI or MRN. For information about the Unlink Master Patient Index Number and Unlink Medical Record Number actions, see the Workflow module reference guide.
