Eligible Dependents are defined in Your Dependents Eligibility. See Qualified Medical Child Support Orders (QMCSOs) for an explanation. Both the Dependent provisions and QMCSO provisions in the section covering eligibility for Non-Medicare Eligible Retirees also apply to eligibility of Dependents of Medicare Eligible Retirees.
Plan benefits for your Dependents will become effective on the same date you become eligible, or if later, on the date you acquire an eligible Dependent. Benefits for your Eligible Dependents are subject to the Coordination of Benefits provision.
