How to Choose Medicare Supplement Insurance

When choosing Medicare supplement insurance, it’s important to consider your personal needs and preferences. While your premium is a big factor, it’s also important to look at other items, including whether you have to worry about copays and coinsurance, and what out-of-pocket costs you’ll have. Also, pay attention to your budget to determine whether it makes sense for you to pay more upfront, or whether you need smaller payments.

Look at various ratings, including A.M. Best and J.D. Power, to see whether a company has good customer satisfaction or its financial health.
