Already have a Medicare Supplement plan and want to switch to another?

Switching can be simple. For plans of equal or less value:

  • Transfer during your annual Open Enrollment Period, which starts on the first day of your birthday month and ends 60 days after your birthday.
  • No medical exam is required.

 

For plans of greater value:

  • Transfer can be done anytime during the year.
  • The applicant must complete a new application and provide responses to all the questions in the Applicant’s Statement of Health questionnaire for underwriting review and approval.

Note: Extra/Innovative plans are considered “equal to” the baseline plan of that type. Subscribers currently enrolled in Medicare Supplement Plan F can transfer to Plan F Extra4, and members currently enrolled in Plan G can transfer to Plan G Extra during their annual Open Enrollment Period without underwriting. (That means no medical exam is required.)

For more switching details, see the Guaranteed Acceptance guide.
