  • Instructions for new Mountaineers enrolling in benefits or Mountaineers experiencing a life event

    Enrolling or updating your benefit elections for 2025

    If you completed your new hire enrollment or submitted your qualified life event benefits changes for 2025 before October 23, 2025, no additional action is needed for your 2025 benefits. Starting October 23, 2025, you can review your benefits options and make changes for 2026 benefits. Follow the instructions under the Take Action section of the 2026 benefits column below.

    If you are completing your new hire enrollment or if you are experiencing a qualified life event between October 23, 2025, and December 31, 2025, update your 2025 benefits by following the instructions under the Take Action section of the 2025 benefits column below. When you finish updating your 2025 benefits, the system will automatically direct you to review your 2026 choices.

    Enrolling or updating your benefit elections for 2026

    Many of your 2025 elections will roll over to 2026; however, you must act if you want to make any of the following updates for 2026:

    • Contribute to a Health Savings Account (HSA) or any Flexible Spending Account (FSA).

    • Update coverage elections to add/remove dependents. Your 2025 spousal surcharge will roll over.

    • Confirm your tobacco use. Your 2025 tobacco use response will roll over.

    • Consider changes to supplemental life insurance coverage: You can increase your coverage by 1x your annual base salary (up to $300,000) without providing information about your health.

    • Update your beneficiaries.

    2026 open enrollment is your chance to review the new plan options and make changes to your coverage. Follow the instructions under the Take Action section of the 2026 benefits column below.

    NOTE: If you are a Mountaineer living in Hawaii and are hired after October 23, 2025, your medical provider will change from Aetna to Kaiser effective January 1, 2026. Please be sure to follow both Take Action links below. This will allow you to elect benefits for 2025 and review benefits for 2026.
