βοΈβοΈAction Required: Verify Your Dependent(s) for Benefits Coverage by Sept 1βοΈβοΈ
What you need to know:
Amentum is conducting a dependent verification audit for company-provided Medical, Dental, and Vision benefits.
To ensure your enrolled dependent(s) remain covered, you must submit the required documents by September 1, 2026.
What you need to do:
Step 1: Check whatβs needed
Log in to www.oneamentumbenefits.com.
Click your name in the top-right corner β select Profile β open Your Dependents to review which dependent(s) need verification and what documents are required.
Step 2: Upload your documents
On the Web: Go to Your Dependents to review documentation requirements and upload files.
On the MyChoice Benefits App: Log in β review tasks at the top of the home screen β open the verification task β snap a picture of your required documents for each dependent.
You may also select Profile β Dependents to review or submit documentation.
Tips:
PDFs or JPEGs work best.
Ensure images are clear, legible, and complete.
Need the app? Itβs available in the Apple App Store and Google Play Store.
Deadline to submit:
Submit your documents by September 1 to ensure your dependent(s) remain covered.
What happens if you donβt submit:
If we do not receive the required documents by September 1 your dependent(s) who are not verified will lose coverage starting October 1, 2026.
Important information:
Losing coverage due to incomplete verification is not a COBRA-qualifying event; continuation of benefits under COBRA will not be available.
You cannot add dependent(s) back to coverage until the next Annual Enrollment, unless you experience a qualifying life event (marriage, divorce, birth, adoption, loss of eligibility under another plan, etc.).
