Enrolling in a Medigap Plan
The best time to purchase a Medicare Supplement Insurance plan is during your Medigap open enrollment period. Your open enrollment period begins as soon as you are at least age 65 years old and enrolled in Medicare Part B. Your open enrollment period only lasts for six months.
During your Medigap open enrollment period, insurance companies cannot deny you coverage or charge more for your monthly premiums based on any preexisting health conditions you might have. If you apply to enroll in Medicare Supplement Insurance outside of your open enrollment period, you may be subject to medical underwriting.
