The term "enrollment period" refers to a specific time frame during which individuals can sign up for or change their health insurance coverage. This is typically an annual event, and it's important that people take advantage of this opportunity because it may be the only chance they have to enroll in a new plan or make changes to their existing one. The exact duration of the enrollment period varies depending on where you live but generally lasts for several weeks during the fall. It’s essential to note, however, that certain life events such as getting married, having a baby, or losing your job may allow you to sign up outside of the regular open enrollment period.
