Medicare supplement plans are available to individuals who are enrolled in Medicare Part A and Part B. Eligibility typically begins at age 65, but younger individuals may qualify if they have certain disabilities. The best time to enroll is during the six-month Medigap Open Enrollment Period, which starts when you turn 65 and enroll in Part B.
