New Hire
Welcome to Lumexa Imaging. Here’s when your benefits start, who you can cover and how to enroll.
When your benefits start
If you are a benefits eligible employee of Lumexa Imaging, most benefits are effective on the first day of the month following your date of hire.
Who you can cover
You may also enroll your eligible dependents for coverage. Eligible dependents are defined as:
- Your legal spouse (or common-law spouse when recognized)
- Children up to age 26, regardless of dependency, student or marital status
- Children 26 or older who are fully dependent on you for support due to a mental or physical disability and are indicated as such on your federal tax return
How to enroll
If your benefits start in November or December 2026, you’ll need to complete two enrollments:
- In your existing benefits portal, for benefits covering the rest of 2026
- In Employee Navigator, for your 2027 benefits
If your benefits start January 1, 2027 or later, you’ll enroll only in Employee Navigator.
To enroll in Employee Navigator:
- Go to Employee Navigator and register as a new user. Enter your first and last name, date of birth, the last 4 digits of your Social Security number and the company identifier Lumexa.
- Select Begin Enrollment and check that your personal information is correct and up to date.
- Review the plan details and make your elections for yourself and your dependents.
- Before you finish, review your enrolled plans, total per-paycheck costs, dependent elections and declined coverages. When you’re ready, click to sign and complete your enrollment.

Need help enrolling?
If you have questions or need help understanding your plan options, call your Alliant Benefit Advocates at 877-531-8820, Monday through Friday from 8 a.m. to 8 p.m. ET.
Before you enroll
- Compare your medical plan options. Look at the HDHP, PPO 2750 and PPO 6000 on total cost, not just your paycheck contribution. See Medical Plans and Employee Costs.
- Check that your doctors are in network. Search for medical providers on UMR (Choice Plus network), dentists on Ameritas (select Classic PPO) and eye doctors on EyeMed.
- Choosing the HDHP? Decide how much to put in your Health Savings Account to have for deductible and other out-of-pocket costs.
- Know the surcharges. A $150 monthly working spouse surcharge and a $100 monthly tobacco surcharge may apply. See Eligibility.
- Name your beneficiaries for life and AD&D insurance.
Changing benefits after you enroll
During the year, you cannot make changes to your benefits unless you have a qualified life event. If you do not make changes to your benefits within 30 days of the qualified life event, you will have to wait until the next annual open enrollment period to make changes (unless you experience another qualified life event).
