Because Learning about Medicare can be like learning a new language. You need to learn the words, understand the main ideas and become fluent. We’re here to make that as easy as possible. Because there are four basic parts of Medicare: A, B, C and D. Each part helps pay for certain health care services. Each part also has certain costs that you may have to pay. Your Medicare costs will depend on what coverage you choose and on what health care services you use. If you’re eligible at age 65, your initial enrollment period begins three months before your 65th birthday, includes the month you turn age 65, and ends three months after that birthday.
However, if you don’t enroll in Part B during your initial enrollment period, you have another chance each year to sign up during a “general enrollment period” from January 1 through March 31. Your coverage begins on July 1 of the year you enroll. Whether you’re new to Medicare, getting ready to turn 65, or preparing to retire, you’ll need to make several important decisions about your health coverage. If you wait to enroll, you may have to pay a penalty, and you may have a gap in coverage.
