To find out which of the supplemental plans will cover you best, you have to compare them. With almost a dozen plans to pick from, there is something there for everyone. Once you compare Medicare Supplement Plans for 2018, you will see that the coverage, while similar, is unique for each plan.
That can make finding the right one a bit difficult, but it is certainly doable. It will help if you start with a base knowledge of what you need to have covered. You should know both what your current medical expenses are and what your state of health is like. This will help you determine what has to be covered. Then you can start looking at the various plans and find the one that fits those needs best.
