Learn when you can sign up and when coverage starts.

Key takeaways

  • Open enrollment is the period of time each year you can sign up for health insurance or make changes to your plan.
  • Each state has a different open enrollment period. Colorado, Idaho, Nevada, and Utah timelines are listed below.
  • If you miss open enrollment, you may have to wait until next year’s open enrollment period to make changes to your insurance coverage.
  • Some people may be able to sign up for or change insurance during a special enrollment period if they have a qualifying life event, such as losing a job or having a baby.

Open enrollment is the time each year when you can make changes to your health insurance plan. Missing the deadlines can mean waiting another year to sign up unless you qualify for a special enrollment period. Because dates vary by state, it’s important to know exactly when you need to act.

When is open enrollment if you get insurance through your job?

If you have health coverage through your employer, your open enrollment timeline may be different than your state’s. Be sure to ask your manager or HR department when your company holds enrollment.

What if you miss open enrollment?

Open enrollment is the only guaranteed time of year you can make changes to or sign up for a health plan. If you miss that window, you might have to wait until next year’s open enrollment to sign up.

There are special circumstances where you may be eligible to sign up for or make changes to a plan outside of open enrollment. This is called a special enrollment period (SEP).

You may qualify for an SEP if you experience one of these qualifying life events:

  • Getting married
  • Getting divorced and losing health insurance as a result
  • Giving birth or adopting a baby
  • A death in the family that results in a loss of health insurance coverage
  • Losing employer-sponsored coverage
  • Losing Medicaid or CHIP eligibility
  • Moving to a new ZIP code or state
  • Turning 26 and aging off a parent’s plan

To find out if you qualify for a special enrollment period, contact our Sales Team at 855-442-0220 (toll-free).
