We need a new segment for person demographics , for use with associated parties, guarantors, subscriber/insureds, etc. All of the demographic information currently in PID for patient plus employer information, should be fields in this new segment. For example, the person segment would be used for patients, guarantors, associated parties and have fields for name, address, sex, ethnicity, and language. But Standard Version 2.3 is adding such fields to NK1, GT1, and IN2. This information would go into Chapter 3.
