The Affordable Care Act (the law known commonly as the ACA or Obamacare) created a nationwide open enrollment period.

• For 2025, open enrollment will run from November 1st, 2024 through December 15th, 2024
• For 2024, it ran from November 1, 2023 through December 15, 2023.
• For 2023 it ran from November 1, 2022 through December 15, 2022.

Here is a list of the 2025 open enrollment dates listed by state.

Keep in mind that if your state runs its own Marketplace, your enrollment period may be different. Check to see if your state has an extended enrollment period here.

During open enrollment, anyone can purchase individual and family health insurance on their own.
However, if you experience a major life-changing event (termed a “qualifying life event” under the law), you may be eligible for a personal special enrollment period outside of Obamacare’s open enrollment season.

What are some qualifying life events?

Qualifying life events that may trigger a special enrollment period for yourself and your family outside of Obamacare’s open enrollment period include the following:

• Marriage or divorce
• The birth or adoption of a child
• The loss of employer-based health insurance coverage
• Moving to a new city outside your old plan’s coverage area
• Changes in income that may make you eligible for Obamacare subsidies

Be aware that you may need to provide documentation showing that you experienced one of these (or other) qualifying life events.

How long will I have to enroll in a new plan?

If you experience a qualifying life event, you will typically have a sixty-day window during which you can enroll in a new Obamacare health insurance plan and apply for Obamacare subsidies if you meet the income criteria.

Supplemental forms of health insurance

Outside the open enrollment period, you can only purchase Obamacare-compliant health insurance if you experience a qualifying life event. However, even if you can’t get an Obamacare-compliant health insurance plan, there are supplemental insurance products available that can offer some level of protection. Although they will not meet your coverage requirements under the Affordable Care Act, and you may still be subject to a tax penalty (which still applies for 2018), this level of protection may still be better than having no coverage at all.

Some alternate forms of coverage may include, but are not limited to, the following:

• Short-term health insurance plans: Short-term plans typically provide temporary coverage for periods of 30 days up to 4 months at a time. They typically will not cover pre-existing conditions or preventive medical care, but they may limit your financial liability for medical bills in case of accidents or other unexpected medical emergencies.
• Accident insurance: Accident insurance plans provide you with a cash payout if you suffer from specific injuries. The payout is made to you rather than to your medical provider, and you can use the money for whatever you choose.
• Critical illness insurance: These plans work like accident insurance but are designed to provide you with a cash payout in case you are diagnosed with a covered serious illness.
• Dental or vision insurance: Dental or vision insurance plans typically provide you with some coverage or discounts for a specific set of dental or vision services within a specific period of time.
