There are specific enrollment periods for health insurance through the Health Marketplace:
Annual Open Enrollment Period: Typically runs from November to mid-December each year. During this time, individuals can enroll in health insurance for the upcoming year, make changes to their existing coverage, or switch plans.
Special Enrollment Period: Available throughout the year for individuals who experience qualifying life events, such as marriage, birth or adoption of a child, loss of other health coverage, or relocation. These events trigger a special enrollment opportunity outside of the regular open enrollment period.
