Learn about Medicare Supplement Plans

Every Medicare Supplement policy must follow Federal and State laws designed to protect you, and the policy must be clearly identified as "Medicare Supplement Insurance.” Medicare Supplement policies are identified by letters "A" through "N" and are "standardized.” Each standardized Medicare supplement policy must offer the same benefits, no matter which insurance company sells it. The plan premium is usually the only difference between policies with the same letter sold by different insurance companies.

The best time to buy a Medigap policy is during your Medicare Supplement open enrollment or a guaranteed issue period. This period lasts for 6 months and begins on the first day of the month in which you're both, 65 or older and enrolled in Medicare Part B.
