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.

There will be no longer medical, prescription drug, and dental coverage through Argonne's group plan.

This change will result in the following benefits:

  • Greater choice
  • Potential equal or better coverage at a lower cost
  • Argonne HRA contribution
  • Flexibility to choose the individual coverage that fits your needs.

Dependents of post-65 retirees will remain under a PPO plan.

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