Enrollment Period

Enrollment Period means, under Medicare's medical insurance (Part B) protection, the period during which a person may sign up for coverage. The initial enrollment period of 7 months begins 3 months before the month in which the person first becomes eligible for the medical insurance protection and ends three months after that month. For those who do not sign up for Part B protection during their initial enrollment period, there is a general enrollment period, January 1 through March 31 of each year, during which they may enroll. For those who apply during a general enrollment period, protection begins the following July.
