Q. What is the deadline to enroll in 2023 ACA-compliant health insurance coverage in the individual market?

A. Open enrollment for 2023 health coverage began in nearly every state on November 1, 2022. (some exceptions: It started on October 15 in Idaho, and starts on November 16 in New York. And in California, open enrollment began November 1 but existing policyholders could begin renewing their coverage as of October 1.)

In most states, open enrollment for 2023 coverage will end on January 15, 2023. And in most states, December 15 is the deadline to get a plan that takes effect January 1; enrollments completed in the latter half of December and the first half of January take effect February 1 instead.

There are some exceptions to this:

  • In New Jersey, Maryland, California, and Nevada, coverage will be effective January 1 as long as the application is completed by December 31
  • In Massachusetts, Rhode Island, and New Mexico, the deadline for a January 1 effective date is December 23.

Open enrollment used to end on December 15 in most states, but the Biden administration added a one-month extension that took effect for the 2022 plan year and will continue to be used from now on. This applies to the 33 states that use The other 17 states and DC are free to follow that same schedule — most do — or set their own schedule.

What are the Obamacare open enrollment deadlines for state-run exchanges?

The states that run their own exchanges can set their own enrollment deadline, as long as it’s not earlier than December 15. For 2023 coverage, as was the case for 2022 coverage, there are 18 fully state-run exchanges that have the option to set their own open enrollment schedules.

Most of these state-run exchanges choose to follow the same November 1 – January 15 schedule that uses. But some have opted for different schedules. Here are the open enrollment windows that the state-run exchanges are using for 2023 coverage (note that the deadlines sometimes change at the last minute, and we’ll keep this page updated as open enrollment progresses; dates that vary from the schedule are shown in bold font):

Who can enroll in ACA-compliant health plans year-round?

Medicaid and CHIP enrollment is available year-round to eligible residents.

Year-round enrollment is also available in the Basic Health Programs in New York and Minnesota. Enrollment is also available year-round for the ConnectorCare program in Massachusetts, for people who are newly eligible or who haven’t enrolled before.

Native Americans and Alaska Natives can enroll year-round in plans offered in the exchange. Applicants who are eligible for Medicaid or CHIP can also enroll year-round. This is true every year, not just in 2021.

And CMS has finalized a new rule that allows subsidy-eligible applicants with income up to 150% of the poverty level to enroll year-round, as long as the American Rescue Plan’s subsidy enhancements remain in effect. The Inflation Reduction Act has extended the subsidy enhancement through 2025, so the low-income special enrollment period will also continue through 2025. This special enrollment period is optional for state-run exchanges, although several of them had already rolled it out as of early 2022.

Does Obamacare open enrollment continue through January 15 in all states?

HHS had previously defined open enrollment as the window from November 1 to December 15, but state-run exchanges have had the option to offer special enrollment periods before or after that window, in order to effectively extend open enrollment.

For coverage effective in 2022 and future years, HHS has changed the enrollment window for It’s now November 1 through January 15. But instead of requiring state-run exchanges to use an enrollment window at least that long, HHS has given them the option of keeping an earlier deadline, as long as it’s not before December 15. This is why Idaho is allowed to continue to have a mid-December enrollment deadline. But all of the rest of the state-run exchanges have opted to extend their enrollment deadlines to January 15 or later.

Fully state-run exchanges are the only ones with the ability to extend open enrollment on their own (in the other states, the decision has to come from CMS, since the extension has to be issued via, and most of them have been choosing to do so each year. But now that HHS has extended the deadline to January 15 for 2022 and future years, many of the state-run exchanges are using that date rather than issuing additional extensions.

Outside of ACA’s open enrollment window, enrollment’s only available with a qualifying event

After open enrollment ends, people can normally only purchase coverage if they have a special enrollment period triggered by a qualifying event such as:

Regardless of whether you purchase insurance through the exchange or off-exchange, the annual open enrollment window applies, and special enrollment periods are necessary in order to enroll at any other time of the year.

Open enrollment schedule has varied over time

Although open enrollment is now set at November 1 – January 15 in most states, it has varied quite a bit over the years. In the federally-run marketplaces, the following enrollment windows have been used (with some last-minute extensions, and with somewhat different schedules used by the state-run marketplaces):

  • 2014 coverage: October 1, 2013 through March 31, 2014
  • 2015 coverage: November 15, 2014 through February 15, 2015
  • 2016 coverage: November 1, 2015 through January 31, 2016
  • 2017 coverage: November 1, 2016 through January 31, 2017
  • 2018 coverage: November 1, 2017 through December 15, 2017
  • 2019 coverage: November 1, 2018 through December 15, 2018
  • 2020 coverage: November 1, 2019 through December 15, 2019
  • 2021 coverage: November 1, 2020 through December 15, 2020
  • 2022 coverage: November 1, 2021 through January 15, 2022
  • 2023 coverage: November 1, 2022 through January 15, 2023

It’s inhuman to put a limited timing for enrolling in a health plan. Enrollment SHOULD be ALL YEAR LONG. You can establish a norm in which once you get a plan, remain on it for a year and don’t allow changes .

That’s how it was pre-ACA, but insurance companies used medical underwriting to determine eligibility in nearly every state, meaning that people with pre-existing conditions either paid more for their coverage, faced exclusions for their pre-existing conditions, or were declined altogether.
Limited enrollment windows have long been the norm for employer-sponsored coverage, which is how most non-elderly Americans get their coverage. The ACA changed individual market coverage to be much more similar to employer-sponsored coverage, including the limited enrollment windows. The idea is to make sure that people are maintaining coverage year-round, instead of waiting until they’re sick to enroll. It’s an essential part of having coverage that’s guaranteed-issue even for people with pre-existing conditions.
But special enrollment periods allow people to sign up for coverage if they experience a bona fide qualifying life event:

seriously i have never understood why there even needs to be an enrollment period limitation at all. I mean, given that it means if someone misses the window, they are barred for as much as a years worth of time from getting coverage, it seems like whatever difficulties might arise from a different system where plans have to re-calculate premiums based on rolling membership adjusting more frequently, would be worth the trouble of the additional complexity.
