What Is Open Enrollment?
Open enrollment is the period during which people can purchase health insurance for the upcoming year. If you don’t sign up for health insurance during open enrollment, there’s a possibility that you won’t be able to sign up for health insurance until the next open enrollment period, unless you experience a qualifying event.

What’s Special Enrollment? Are There Exceptions?
Regardless of whether you purchase insurance through the exchange or off-exchange, the annual Obamacare open enrollment window applies, which is why it’s very important to pay close attention to the enrollment deadlines.
You cannot enroll outside of open enrollment unless you have a qualifying event. And the rules for special enrollment periods are stricter than they used to be. In most cases, you’re required to have already had coverage prior to the qualifying event in order to sign up for a new plan as a result of the qualifying event (for example, if you move to a new area, it’s only a qualifying event—allowing you to sign up for a plan in your new area—if you already had coverage in your previous location). The restrictions on special enrollment periods make it more important than ever for people to sign up during open enrollment, when those restrictions don’t apply.
Does The Open Enrollment Period Matter If I Already Have Insurance?
Yes, even if you are already insured and happy with your plan, there are a few things to pay attention to during open enrollment season. During open enrollment season, make sure you note how much your premium will change in the coming year and if this is still feasible for you and your family. Additionally, some benefits of your plan or coverage details may change in the coming year. Make sure that you are aware of these changes before open enrollment period ends, as most states will not let you make changes to your plan after mid-December.
What If I Get Coverage From My Employer?
If you are hired as an employee at a new job, you do not need to wait until the open enrollment period to get covered by their health insurance. The open enrollment period employer health insurance may overlap with the regular open enrollment period, or it may be a few weeks earlier. Check with your employer to find out when their open enrollment period will be and if they are making any changes to the plan in the coming year.
