You'll get a personalized experience, guiding you step-by-step through the process. We will only ask you for information that relates to your situation.

Before you get started

You'll need:

  • Enrollee ID cards from all other plans.
  • Full name and birth date for each person covered by other insurance.
  • If you or someone on your account also has Medicare, you’ll need the Medicare card issued by the government.
  • If someone on your plan has other insurance because of a court order from the Friend of the Court or a divorce decree, you’ll need those legal documents.
