Enrollment Information

The first step (if you have not already done so) is to pick the right health plan for you and your family. To help you make the best decision Aetna offers the Plan Selection & Cost Estimator Tool. With this tool, you can estimate how much your family’s health care needs may cost and review the recommended preventive medical care for each family member based on age and gender and the average cost of medical services needed for you and your family.

For information about how to enroll in or make changes, please contact the MITRE HR Service Center by phone or mail.

Once your enrollment is complete, you’ll want to register for Aetna Navigator, your secure member website. Then you can start enjoying all of your plan’s many tools and extras, such as the member discount programs (PDF).
