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.
Original Medicare offers basic hospital and medical insurance coverage. But you may find that it does not cover the cost of all the services and supplies you need.
