Medicare in Massachusetts can be very mysterious to many people.  Let's face it, insurance of any kind is complicated.  After spending the past six weeks attempting to understand the complexities of Medicare in my home state of Massachusetts, I decided to share what I've learned with others. During the next six weeks, I will provide some basics of Medicare, along with links for further information.  We'll cover five topics: Medicare part A, part B, part C, part D, and supplemental/gap insurance.
