Date of Birth
 
(01/01/21 – 12/31/21)
A date of birth (DOB) must be listed for each participant.
 
In AZTECS, when the DOB is known, key as MMDDYYYY (e.g., 06091996 for June 09, 1996) on SSDO.
 
When the DOB is unknown, use the approximate date of July 01 and key as 0701 (MMDD) and the approximate year of birth (YYYY).
 
In HEAplus, when the DOB is unknown, the same procedure is followed. Enter July 01, when entering the DOB on the Member Information page, with the approximate year of birth.
 
For an unborn child, key the expected delivery date (EDD) as the DOB.
