This "unaffiliated person" class is used to convey a minimal amount of information about a Person who is not fully enumerated in an organization's data systems. This class can be used for points of contacts for external organizations, healthcare providers who work for other organizations (e.g., this medical record was received from a Dr. Smith), as well as other persons who play an ancillary role in the provision of care to the patient (e.g., a taxi driver who brings the patient to weekly appointments, etc.) This class contains only the name of the person, and optionally address(es) and/or phone number(s). No other information, such as birthdate, gender, or identifiers such as a social security number, tax id number, or national provider number are needed and indeed will often not be known.
