What Is a Special Enrollment Period?
Florida ACA Marketplace Open Enrollment runs from November 1 through January 15 each year. Outside of that window, you generally cannot enroll in or change a Marketplace plan — unless you experience a qualifying life event that triggers a Special Enrollment Period (SEP). An SEP is a time-limited window, usually 60 days, during which you can enroll in or change your Marketplace coverage regardless of the time of year.
SEPs exist because life changes — job loss, marriage, a new baby — do not align neatly with an annual enrollment window. Without SEPs, millions of Americans would face gaps in coverage simply because their life changed at the wrong time of year. For Florida residents, the SEP rules are the same as for all HealthCare.gov states, since Florida did not create its own state-based exchange.
Qualifying Events That Trigger an SEP
The Marketplace recognizes several categories of qualifying events. Each has specific documentation requirements and a 60-day enrollment window from the date of the event.
| Qualifying Event | SEP Window | Common Documentation |
|---|---|---|
| Losing job-based or other coverage | 60 days from coverage end date | Employer termination letter, COBRA notice |
| Marriage | 60 days from wedding date | Marriage certificate |
| Divorce or legal separation | 60 days from finalization | Divorce decree, separation agreement |
| Birth of a baby or adoption | 60 days from birth/adoption | Birth certificate, adoption decree |
| Moving to a new coverage area | 60 days from move date | Lease, utility bill, or mortgage with new address |
| Turning 26 (aging off parent's plan) | 60 days from birthday | Prior coverage termination letter |
| Losing Medicaid or CHIP | 60 days from termination | Termination notice from FL Medicaid |
| Income change — gaining Marketplace eligibility | 60 days from change | Pay stub, employer letter, tax documents |
The Most Common SEP: Losing Job-Based Coverage
By far the most frequently used SEP in Florida is the loss of employer-sponsored coverage. When you leave a job, are laid off, or your employer stops offering benefits, your coverage ends and a 60-day SEP clock starts on the date coverage ends — not the date you receive notice. Act quickly, because waiting too long can mean a gap in coverage between when your employer plan ends and when your new Marketplace plan begins.
One important clarification: voluntarily canceling your current coverage does not trigger an SEP. The loss must be involuntary or due to a qualifying change — such as a job ending, leaving full-time status, or a dependent aging off a plan. If you simply decide you no longer want your current individual plan, you must wait for Open Enrollment.
The SEP window starts when coverage ends, but you can begin your application up to 60 days before you lose coverage. If you know your last day of employer coverage in advance, start shopping plans now so your new coverage begins the day after your old plan ends. There will be no gap in coverage if you time it correctly.
Marriage SEP
Getting married gives both spouses a 60-day window to enroll in or change a Marketplace plan. This is true even if both spouses already have individual coverage — marriage can change the household income calculation significantly enough to warrant a plan review. After marriage, you can enroll together on a family plan or keep separate plans, whichever is more cost-effective.
To use the marriage SEP, you will need to upload a copy of your marriage certificate to HealthCare.gov within 30 days of enrolling.
Birth or Adoption SEP
A new baby or adoption immediately triggers an SEP. The newborn is covered from the date of birth even if the enrollment paperwork is completed later, as long as you enroll within 60 days. This is one of the most important SEPs to use promptly — a newborn with no health coverage is a serious financial and health risk. Adding a dependent to your Marketplace plan works the same way whether the child is born, adopted, or placed in foster care.
Moving SEP
Moving to a new ZIP code in Florida can qualify for an SEP if your move results in new plan options being available. If you move to a different service area where your current insurer has no coverage, you must enroll in a new plan. If you move within the same coverage area and your current plan remains available, you generally do not qualify for a moving SEP — this is a common misunderstanding. Moving from another state to Florida always qualifies, since you are gaining access to entirely new plans.
Moving SEPs require documentation showing your old and new addresses. Keep a utility bill or lease agreement from both addresses. HealthCare.gov typically requests documentation within 30 days of enrollment. If you cannot produce proof, your SEP enrollment can be cancelled retroactively, leaving you with a coverage gap and a bill for premiums you already paid.
Turning 26: Aging Off a Parent's Plan
Young adults in Florida who turn 26 lose eligibility for coverage under a parent's health insurance plan. This triggers a 60-day SEP to enroll in your own Marketplace plan. If you have employer coverage available through your own job, you should first consider whether that coverage is affordable — if it meets affordability rules, you may not qualify for Marketplace subsidies.

Losing Medicaid or CHIP in Florida
If you are terminated from Florida Medicaid or KidCare (Florida's CHIP program), you have a 60-day SEP to enroll in a Marketplace plan. Florida conducts periodic Medicaid eligibility redeterminations, and many enrollees who gained Medicaid during the COVID-era continuous enrollment period have been disenrolled in recent years. If you received a disenrollment notice, act immediately — do not wait until your last day of Medicaid to start your Marketplace application.
If your income drops and you become eligible for Marketplace subsidies for the first time — for example, moving from above 400% FPL to below — that change in circumstances can trigger an SEP. You must demonstrate the income change to HealthCare.gov. Similarly, if income rises and you no longer qualify for Medicaid (in expansion states), that triggers an SEP as well. In Florida, the Medicaid income threshold is low and primarily covers children and certain adults, so the income-rise SEP from Medicaid is less common.
How to Submit SEP Documentation on HealthCare.gov
- Log in at healthcare.gov and complete your enrollment application
- Select your SEP type from the list of qualifying events
- Choose your new plan and complete enrollment
- Upload supporting documents within 30 days (HealthCare.gov will prompt you)
- Monitor your account for a verification confirmation — coverage begins once verified
If HealthCare.gov is unable to verify your SEP through automated data-matching, you will receive a notice requesting additional documentation. Respond promptly — typically within 90–100 days — or your coverage may be cancelled.
