If the patient is either an employee or a student, enter the appropriate name in this box. An entry here is REQUIRED. If there is no group or FECA number, then type in either [1] capitalized N/A which will appear in the box on the CMS-1500 form or [2] lower case n/a which will leave the box blank. If this box is left blank, the patient will be listed in the Pre-Billing Tab of the Insurance Manager which will hold and NOT produce claims until this item has been entered.
