Yes, losing health insurance is a qualifying life event. It opens a Special Enrollment Period that lets you sign up for a new health plan through the Marketplace or an employer outside of the regular open enrollment window. You generally have 60 days to act, though the exact timeline depends on the type of coverage you lost.
What Counts as a Qualifying Loss of Coverage
Most involuntary losses of health coverage qualify. The list is broader than many people realize:
- Job-based insurance: You lose coverage because you were laid off, fired, quit, had your hours reduced, or your employer dropped the plan.
- A parent’s plan: You turn 26 (or your state’s maximum dependent age) and age off a parent’s policy.
- Divorce, separation, or death: You were covered through a spouse or family member and lost that coverage due to divorce, legal separation, or the family member’s death.
- Medicaid or CHIP: You lose eligibility because of a change in income, a renewal redetermination, or your child ages out of CHIP.
- Student health plans: You lose eligibility for a college or university plan.
- Plan discontinued: Your individual or Marketplace plan is canceled or no longer offered.
- You moved: You no longer live in your plan’s service area.
- COBRA exhaustion: Your COBRA coverage runs out after the full maximum period (typically 18 or 36 months).
- Medicare Part A: You lose premium-free Medicare Part A coverage.
Even a drop in household income can qualify if it makes you newly eligible for Marketplace savings you weren’t getting before.
What Does Not Count
Not every loss of coverage triggers a Special Enrollment Period. The key distinction is whether the loss was involuntary or within your control. If you voluntarily cancel your plan or stop paying your premiums and your coverage lapses, that generally does not qualify. The same applies if you drop COBRA coverage early before the maximum period runs out. The Department of Labor is explicit on this point: to use COBRA exhaustion as a qualifying event, you must receive the full maximum period of continuation coverage without terminating it early. If you cut COBRA short, you’ll typically have to wait for the next open enrollment period.
How Much Time You Have
For most types of coverage loss, you have a 60-day window. That window works in both directions: you can apply up to 60 days before your coverage ends or up to 60 days after it ends. This means you don’t have to wait until you’re actually uninsured to start shopping for a new plan. If you know your last day of coverage is coming, you can enroll early and avoid any gap.
Medicaid and CHIP get a longer window. If you lost Medicaid or CHIP coverage, you have 90 days after the loss to qualify for a Special Enrollment Period on the Marketplace. You also have 60 days to request special enrollment in an employer-sponsored plan if one is available to you.
When New Coverage Starts
If you enroll in a Marketplace plan during a Special Enrollment Period, coverage typically begins on the first day of the month after you select your plan. So if your old coverage ends February 5 and you pick a new plan on January 29, the new plan kicks in February 1, giving you no gap at all. These dates can vary slightly in states that run their own Marketplace, but the general rule is first-of-the-next-month.
This is why acting before your coverage ends matters. If you wait until after you’re already uninsured, you could end up with a few weeks without any coverage before the new plan’s effective date.
Documents You’ll Need
The Marketplace may ask you to prove that you actually lost coverage. Your documents need to include your name and the date coverage ended (or will end). Acceptable proof includes:
- A letter from your insurance company showing cancellation or termination of your policy, printed on official letterhead.
- A letter from your employer confirming that your coverage was dropped, that the employer stopped contributing to costs, or that benefits changed in a way that ended qualifying coverage.
- A COBRA letter from your employer or insurer confirming when COBRA coverage ended or will end.
- Divorce or separation papers showing the date health coverage responsibility ended, if that’s the reason you lost coverage.
- A death certificate along with proof you were covered through the deceased family member’s plan.
If your plan operated on a non-calendar year and you’re losing coverage mid-year, a signed letter from your insurance agent or company stating when the coverage year ends will work.
Employer Plans Have the Same Rule
The qualifying event concept applies to employer-sponsored plans too, not just the Marketplace. If you lose outside coverage, such as Medicaid, a spouse’s plan, or a parent’s plan, your employer’s group health plan must allow you to enroll during a special enrollment window. You typically have 60 days from the loss of coverage to make that request. This is true even if you previously declined your employer’s plan during regular enrollment.
If you have access to both an employer plan and a Marketplace plan, compare costs carefully. Employer plans don’t always offer Marketplace-style premium subsidies, but they sometimes have lower out-of-pocket costs or broader provider networks.
