New Mountaineers or Qualified Life Events after Oct. 22

How to enroll for your 2026 and 2027 benefits

New Mountaineers and current Mountaineers experiencing a qualifying life event need to enroll in benefits for the remainder of 2026 and review benefits options for the full 2027 calendar year. The information below will assist you in managing your new enrollment or benefit changes during this period.

What is a qualifying life event? This is a major life change, such as getting married, having a baby, or a change in partner coverage. If you experience one of these events, you must update your benefits within 30 days of the event.

    Enrolling or updating your benefit elections for 2026

    If you completed your new hire enrollment or submitted your qualified life event benefits changes for 2026 before October 22, 2026, no additional action is needed for your 2026 benefits. Starting October 22, 2026, you can review your benefits options and make changes for 2027 benefits. Follow the instructions under the Take Action section of the 2027 benefits column below.

    If you are completing your new hire enrollment or if you are experiencing a qualified life event between October 22, 2026, and December 31, 2026, update your 2026 benefits by following the instructions under the Take Action section of the 2026 benefits column below. When you finish updating your 2026 benefits, the system will automatically direct you to review your 2027 choices.

    Enrolling or updating your benefit elections for 2027

    Most of your 2026 benefit elections will carry over to 2027 automatically. However, you must log in and make an active election if you want to:

    • Change your medical plan: The Choice PPO Plan will no longer be offered in 2027. If you enrolled in the Choice PPO Plan for 2026 and do not select a new plan during Open Enrollment for 2027, you and your dependents will be automatically enrolled in the Enhanced HDHP.

    • Contribute to an HSA or FSA: Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) do not automatically roll over. You must re-enroll to choose your 2027 contribution amounts.

    • Update dependent coverage: Add or remove family members from your plan (your 2026 spousal surcharge status will roll over).

    • Modify your tobacco status: Update your tobacco use response (your 2026 selection will roll over).

    • Increase your Life Insurance coverage: In 2027, Iron Mountain will pay for Basic Life and AD&D insurance at 1x your annual pay (up to $500,000).

    • Add supplemental life insurance: Enroll in or increase your voluntary coverage.

    • Update your beneficiaries: Review and confirm who will receive your life insurance benefits.

    • Enroll in MetLife legal: Sign up for legal coverage or expand your plan to cover parents, in-laws, and grandparents in 2027.

    2027 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 2027 benefits column below.
