A change file contains only those dental members associated with an individual dental provider/PCD who have changed since the last file was produced. A change file will contain change, addition and terminated transaction types. A member who terminated since the last file will appear on the first subsequent change file but not on any future files.
For members enrolled in DMO plans, this data will contain the Aetna subscriber number. This is the number under which the family is enrolled in Aetna systems. All members of the family (subscriber and dependents) will have the same number.
