Description: The Health Level Seven (HL7) Identification and Cross-Reference Service (IXS) is a standard that defines the functions, responsibilities, inputs, outputs, and expected behavior of a system of components for managing identities, such as would be used in a Master Patient Index (MPI). The HL7 IXS is not limited to patients and can be equally applied to manage identities for staff, providers, facilities, or any other `entities` needing identity management.
