Except for coverage of a newborn or adopted child, changes in coverage will begin the first day of the month following the qualifying event. Coverage for a newborn is effective on the child's date of birth, or in the case of an adopted child, on the date of placement. The premium for coverage of a newborn or adopted child is due in the birth month if the child is born on the 1st of the month, or in the case of an adoption, if the date of placement is the 1st of the month. Otherwise, the premium is not due until the following month.
