Medicare Enrollment Periods Overview
Medicare includes several enrollment periods established by the Centers for Medicare & Medicaid Services (CMS). The Initial Enrollment Period (IEP) generally begins three months before an individual turns age 65, includes the month of their 65th birthday, and ends three months afterward.
Individuals who do not enroll during their Initial Enrollment Period may be eligible to enroll during the General Enrollment Period or may qualify for a Special Enrollment Period (SEP) based on certain life events or other circumstances recognized by CMS. Eligibility requirements, enrollment timeframes, and any applicable late enrollment penalties are determined by federal Medicare rules and may vary depending on an individual’s circumstances.
