Argonne National Laboratory

For Retirees

Beginning January 2017, Medicare-eligible retirees age 65 or older and their Medicare eligible dependents age 65 or older will purchase individual health insurance (i.e., medical, prescription drug and dental) through a private health exchange managed by Aon Hewitt. A health reimbursement account (HRA) will be established to help you pay for the coverage you select in the Aon Retiree Health Exchange. The amount Argonne contributes will be reviewed and established on a calendar year basis.

Dependents under age 65 of retirees age 65 and older may participate in Argonne's pre-65 retiree group health care plans.

Pre-65 retirees and dependents are not affected by this change.
