Retirement is no longer just a one-and-done activity. More people are experiencing retirement in phases as they work longer at second careers or part-time work and adjust their housing needs several times to meet their lifestyle. It's the same with Medicare coverage. With so many changes in Medicare plans and so many options it is smart to review and compare Medicare plans every year. Know the Medicare moving rules if you are relocating. Check your prescription drug plan every year as prices and benefits changes. And have a Medicare supplement plan and are health enough to pass health questions, there may be a more affordable plan available to you.
