Initial Enrollment Period (IEP)

The Initial Enrollment Period (IEP) is the first opportunity for individuals to enroll in Medicare when they become eligible. For most people, the IEP occurs when they turn 65 and lasts for seven months, beginning three months before the month of their 65th birthday and ending three months after. During the IEP, individuals can sign up for Medicare Part A and/or Part B, as well as select additional coverage options such as Medicare Advantage (Part C) or Medicare prescription drug coverage (Part D). It’s important to enroll during this period to avoid potential late enrollment penalties.
