Enroll in a plan

You have automatically been enrolled in the UnitedHealthcare Group Medicare Advantage (PPO) plan, sponsored by Navistar, Inc. You don't need to fill out an enrollment form or take any further action.

What am I enrolled in?

You're enrolled in the UnitedHealthcare® Group Medicare Advantage (PPO) plan. To learn more about your plan details, review plan benefits and costs.

What happens after enrollment?

If you have chosen not to opt-out of your plan, your employer will send your enrollment information to us. After we receive it, here's what you can expect:

  1. We'll review your information and eligibility.
  2. After you're verified, your information will be sent to the Centers for Medicare & Medicaid Services (CMS) for approval. Approval may take up to one week.
  3. Once CMS approves your enrollment, you will be sent a confirmation letter and your plan member ID card.
  4. Soon after, you will receive your Member Kit in the mail. It includes details about your specific health plan benefits.
  5. Watch for your Annual Notice of Changes, which is mailed to you every year you're a plan member. It describes your benefits, and any changes to them, for the next calendar year.

Need help or have questions?
