Missing Open Enrollment does not automatically mean waiting until November. What it does mean is that your options narrowed considerably at the end of 2025, when the year-round enrollment path many lower-income households relied on was permanently eliminated. What’s left is a set of qualifying life events, each with a strict 60-day window.
Here is what still qualifies, what no longer does, and how not to miss the clock.
The 60-day rule
Most qualifying life events trigger a Special Enrollment Period (SEP) of 60 days, either before or after the event depending on the type. Miss it, and you are generally back to waiting for the next Open Enrollment — there is no grace period, and “I didn’t know” does not extend the window.
The main qualifying life events
| Category | Examples |
|---|---|
| Loss of coverage | Job loss, employer coverage ending, COBRA exhaustion, aging off a parent’s plan at 26, losing Medicaid or CHIP eligibility |
| Household changes | Marriage, birth, adoption or placement for adoption, certain cases of divorce or legal separation resulting in coverage loss |
| Moving | A permanent move to an area with different plan options, or into coverage for the first time |
| Income or eligibility changes | A change that affects your eligibility for premium tax credits or cost-sharing reductions |
| Other | Gaining citizenship or lawful presence, leaving incarceration, a marketplace enrollment error, and other exceptional circumstances such as a natural disaster |
Each category has its own documentation requirements and its own rule on whether the window runs before or after the event. Losing other coverage, for example, generally gives you 60 days before or after the loss date, while having a baby generally gives you 60 days after the birth.
What Does Not Qualify
Some situations feel like a qualifying event but are not:
- Voluntarily dropping your coverage
- Losing coverage because you stopped paying premiums
- Coverage that ended because of fraud or intentional misrepresentation
- Losing coverage more than 60 days ago
- Losing a short-term limited-duration plan, which is not qualifying coverage
- Moving only for medical treatment or vacation
The low-income SEP is gone — what that means for 2027
Through 2025, anyone with household income up to 150% of the federal poverty level could enroll or switch plans essentially year-round, without needing a qualifying life event. That provision was phased out through 2025 and 2026 and permanently eliminated by federal rule in May 2026.
If your income is under 150% FPL, you no longer have that standing option. You now need either the standard Open Enrollment window or one of the qualifying life events above, the same as everyone else. A small number of states run their own Basic Health Program or similar alternative with different year-round rules (including Washington D.C., Oregon, Minnesota, Massachusetts, Connecticut and New York) — worth checking if you’re in one of those states, but it is no longer a nationwide fallback.
When Your Coverage Starts
Start dates depend on the event and on when you pick a plan, according to the CMS Special Enrollment Period guide.
| Event | When coverage starts |
|---|---|
| Loss of other coverage, plan chosen before the loss | First day of the month after your old coverage ends |
| Loss of other coverage, plan chosen after the loss | First day of the month after you pick a plan |
| Birth, adoption or foster placement | Retroactive to the date of the event; you can ask for the first of the next month instead |
| Marriage | First day of the month after you pick a plan |
| Permanent move | First day of the month after you pick a plan |
For marriage and a move, you generally need to have had qualifying health coverage for at least one day in the 60 days before the event, with exceptions such as moving from abroad or a U.S. territory.
What documentation to have ready
- Proof of the event. A termination letter, marriage certificate, birth certificate, or lease/utility bill showing a new address, depending on the event.
- Timing. Apply within 60 days of the event. Don’t wait to “get organised” first — you can start the application and add documentation as you gather it.
- Coverage start date. This depends on the event and when you enroll. Some events (like birth or adoption) can make coverage retroactive to the event date; others start on the first of the following month.
What Happens After You Apply
For loss-of-coverage events, HealthCare.gov must verify your eligibility before your enrollment goes through. After you pick a plan, you generally have 30 days to submit supporting documents, and you cannot use the coverage until verification is resolved and your first payment is made. Other event types may also be checked, so keep your documents handy.
Options That Do Not Depend on a Window
- Medicaid and CHIP. If you are eligible, you can apply at any time of year.
- Tribal members. Members of federally recognized tribes can change Marketplace plans once a month.
- State programs. Some states run their own programs with year-round enrollment, as HealthInsurance.org lists for the District of Columbia, Oregon, Minnesota, Massachusetts, Connecticut and New York.
Where this connects to your subsidy and plan choice
Qualifying for a Special Enrollment Period doesn’t change what you’re eligible for financially — the same 2027 income rules apply as they would during Open Enrollment. See ACA subsidy eligibility for 2027 for the current income bands, and if the event is tied to a job change, Marketplace vs. employer coverage for how to weigh a new employer offer against a marketplace plan. Once you know you qualify, our plan selection guide covers how to actually choose between what’s available to you.
Frequently Asked Questions
How long is a Special Enrollment Period?
Most last 60 days from the qualifying event. For loss of coverage you can report the change up to 60 days before it happens and have 60 days after it to pick a plan.
What happens if I miss the 60-day window?
In most cases you will need to wait for the next Open Enrollment period, unless a new qualifying event occurs in the meantime. This is why acting quickly matters now that the year-round low-income option is gone.
When does my coverage start after a qualifying event?
It depends on the event. For most, coverage starts the first day of the month after you pick a plan. For a birth or adoption it can be retroactive to the date of the event.
What events do not qualify for a Special Enrollment Period?
Voluntarily dropping coverage, losing coverage because you stopped paying premiums, and moving only for medical treatment or vacation do not qualify. Dissatisfaction with your plan is not a qualifying event either.
Does losing subsidy eligibility itself count as a qualifying event?
Not on its own. A change in the income or circumstances that caused the eligibility change may qualify under income or eligibility changes, but simply owing more or less than expected at tax time is not by itself a trigger.
Can I switch plans mid-year just because I do not like my current one?
No. Dissatisfaction with a plan is not a qualifying life event. You would need to wait for Open Enrollment unless one of the listed events genuinely applies.
Can I enroll in Medicaid or CHIP at any time?
Yes. If you are eligible, you can apply for Medicaid or CHIP at any time of year without waiting for a Special Enrollment Period.
If you think you qualify
The clock starts the day the event happens, not the day you get around to dealing with it. Get in touch as soon as a qualifying event occurs and we’ll confirm your window, help gather documentation, and run your subsidy eligibility at the same time so you’re not enrolling blind.
