Health insurance enrollment doesn't work like most purchases—you can't sign up or switch whenever you want. There are specific windows when enrollment is allowed, and missing them can mean going months without coverage. Understanding Florida's enrollment calendar helps you plan ahead and avoid gaps.
Annual Open Enrollment: The Primary Window
The ACA marketplace open enrollment period for Florida runs each year from November 1 through January 15. This is the primary window when any Floridian without disqualifying employer coverage can enroll in or change a marketplace plan.
| If You Enroll By | Coverage Starts |
|---|---|
| December 15 | January 1 |
| January 15 | February 1 |
To avoid any gap in coverage, enroll by December 15. If you already have a plan, it will auto-renew if you do nothing—but always review your plan before auto-renewing because terms change.
Special Enrollment Periods (SEPs)
Outside of open enrollment, you can only enroll in a marketplace plan if you have a qualifying life event. Each qualifying event opens a 60-day Special Enrollment Period. The event must be documented and reported to the marketplace within the 60-day window.
Qualifying Events That Trigger a 60-Day SEP
- Loss of health coverage: Losing employer coverage, COBRA ending, Medicaid termination, or aging off a parent's plan at 26. (Note: voluntarily dropping coverage does not qualify.)
- Household changes: Marriage, divorce, birth, adoption, death of a covered dependent.
- Address change: Moving to a new state, county, or zip code that results in different plan availability.
- Change in citizenship or immigration status
- American Indian/Alaska Native: Tribal members can enroll once per month year-round.
- Gaining eligibility or ineligibility for Medicaid/CHIP
- Certain errors or misinformation by a marketplace representative
Employer Plan Enrollment Deadlines
Employer-sponsored plans have their own open enrollment periods, which vary by employer—typically in October or November for January 1 coverage. Newly hired employees generally have 30–60 days after their start date to enroll. After that, they must wait for the employer's open enrollment or a qualifying life event. Check with your HR department for exact deadlines.
Medicare Enrollment Deadlines
Medicare has its own enrollment windows that differ from the ACA marketplace:
- Initial Enrollment Period: 7-month window around your 65th birthday (3 months before, the month of, and 3 months after). Enroll during this window to avoid late enrollment penalties.
- Annual Enrollment Period (AEP): October 15 – December 7 each year to switch Medicare Advantage or Part D plans.
- General Enrollment Period: January 1 – March 31 for people who missed their Initial Enrollment Period.
If you're on a marketplace plan, it may auto-renew—but plans change. A plan that auto-renews may have different premiums, a different network, or a different drug formulary than last year. Always log in to HealthCare.gov and actively review your plan before the December 15 deadline.
Florida Medicaid Enrollment
Florida Medicaid has no open enrollment period—you can apply at any time. If you're eligible, coverage begins shortly after approval (often retroactive to the application date). Apply through ACCESS Florida at myflorida.com/accessflorida.
Enrollment timing can be complicated, especially if you're transitioning between coverage sources. Talk to a licensed Florida advisor to make sure you enroll at the right time with no gaps in coverage.
