Open Enrollment

Core Takeaways

• Open enrollment is the period when you can sign up for or change health insurance plans.
• ACA open enrollment typically runs from November 1 to January 15.
• Missing open enrollment means you may have to wait until next year.
• Special enrollment periods are available for qualifying life events.

What is Open Enrollment?

In plain English: Think of open enrollment like a yearly window of opportunity. It’s your chance to pick or change your health insurance plan. Miss the window, and you’ll have to wait until next year—unless something major happens in your life.

When is Open Enrollment?

The timing of open enrollment varies depending on the type of health insurance:

• ACA Marketplace: Typically November 1 to January 15
• Employer-sponsored plans: Usually in the fall (October-November)
• Medicare: October 15 to December 7
• Medicaid/CHIP: Year-round in most states

Plan Type	Open Enrollment Period	Effective Date
ACA Marketplace	Nov 1 - Jan 15	Jan 1 (if enrolled by Dec 15)
Employer Plan	Oct-Nov (varies)	Jan 1
Medicare	Oct 15 - Dec 7	Jan 1
Medicaid	Year-round	Varies by state

What You Can Do During Open Enrollment

• Enroll in a Plan — Sign up for health insurance for the first time
• Change Plans — Switch to a different health plan
• Renew Coverage — Keep your current plan (may auto-renew)
• Update Info — Report changes in income or household

Important: I always tell people to review their plan during open enrollment, even if they’re happy with it. Premiums and benefits can change from year to year, and there might be a better option available. I used our health insurance comparison tool last year and found a plan that saved me $300/month!

Special Enrollment Periods

You can enroll in or change health insurance outside of open enrollment if you experience a qualifying life event:

• Losing health coverage (job loss, COBRA expiration)
• Getting married or divorced
• Having a baby or adopting a child
• Moving to a new area
• Changes in income that affect eligibility

What Happens If You Miss Open Enrollment?

If you miss open enrollment and don’t qualify for a special enrollment period, you’ll generally have to wait until the next open enrollment period. However, you may be able to:

• Apply for Medicaid or CHIP (if eligible)
• Get short-term health insurance
• Wait for the next open enrollment period

Frequently Asked Questions

Can I change my health plan outside of open enrollment?

Generally, no. You can only change plans outside of open enrollment if you qualify for a special enrollment period due to a qualifying life event.

What is a qualifying life event?

Qualifying life events include things like losing health coverage, getting married, having a baby, moving to a new area, or changes in income.

Does my employer plan have the same open enrollment period as the ACA Marketplace?

No, employer plans typically have their own open enrollment periods, usually in the fall (October-November).

What if I’m happy with my current plan?

Even if you’re happy with your plan, it’s still a good idea to review it during open enrollment. Premiums, benefits, and provider networks can change, and there might be a better option available.
