The Groups guide to open enrollment

Open enrollment is the easiest time of year for changing health insurance. It’s a great time to get coverage if you don’t have it. Someone might want to change their plan if it doesn’t cover what they need it to. 

In open enrollment, you can select a new plan on your state’s Marketplace site. If you prefer, you can call the phone number listed online. The rest of the year, you’ll need a “qualifying life event” to change your plan. These include marriage, having kids, losing coverage, or income changes.

The timing of open enrollment depends on your health plan. Medicare open enrollment is October 15, 2023 through December 7, 2023. For Marketplace and public plans, it’s November 1, 2023 through January 15, 2024. (Most employer plans have their own open enrollment periods.)

This is what you need to know about open enrollment.

What you need to know if you have Medicaid or Medicare

Not every Medicaid plan offers the same benefits. Learn about your current plan’s benefits, so you can choose the best one for you. You can get a full list of benefits from your plan’s site.

With Medicare, make sure your current coverage is meeting your needs. It’s important that it covers most of your health care services. This may include primary care appointments, Groups treatment, and medication. You can change your Medicare plan and/or get more coverage by adding Part B or Part D.

What you need to know if you have private health insurance

Like public plans, private plans (commercial or employer) vary in what they cover. Review and compare your current plan, so you can find the right one for you. 

In some states, the Marketplace will re-enroll you for another year. If this is the case in your state, you should have received a letter in the mail. If you’re not sure, reach out to

What you need to know if you don’t have health insurance

If you don’t have coverage, it’s good to look into what you qualify for. If you haven’t qualified for free or low-cost plans before, you may this year. (Did your income change? Are you 65 or older? Do you have a disability? Are you pregnant or did you have kids?)
