This comprehensive Florida Open Enrollment Calendar will help you understand every major enrollment period so you never miss an important deadline.
Why Enrollment Dates Matter
Unlike auto insurance or life insurance, health insurance generally cannot be purchased whenever you want.
Most health insurance plans have limited enrollment windows.
Missing one deadline could mean:
- Going months without coverage
- Paying expensive medical bills out-of-pocket
- Waiting until the next enrollment period
- Losing premium tax credits
- Missing the opportunity to change Medicare plans
Fortunately, many people qualify for Special Enrollment Periods throughout the year.
Florida Individual & Family Health Insurance Calendar (Marketplace/ACA)
Florida uses HealthCare.gov for Marketplace health insurance enrollment.
For 2026 coverage, the Marketplace Open Enrollment Period ran:
November 1, 2025 – January 15, 2026. Consumers enrolling by December 15 received January 1 coverage, while later enrollments generally became effective February 1.
For future years, federal rules shorten the HealthCare.gov enrollment window beginning with the fall 2026 enrollment season for 2027 coverage, making it even more important to enroll early.
Florida Health Insurance Annual Calendar
January
- New Marketplace plans begin
- Medicare Advantage Open Enrollment begins
- Continue Marketplace enrollment if still within the federal enrollment window (when applicable)
February
Coverage begins for January Marketplace enrollments.
This is also a good month to:
- Verify your doctors are in-network
- Transfer prescriptions
- Set up automatic premium payments
- Review your deductible and copays
March
Last month of Medicare Advantage Open Enrollment (ends March 31).
During this period Medicare Advantage members may:
- Switch Medicare Advantage plans

- Add a Part D drug plan if returning to Original Medicare
April – June
Generally no Marketplace Open Enrollment.
However, you may qualify for a Special Enrollment Period if you experience a qualifying life event.
Examples include:
- Marriage
- Divorce
- Birth or adoption
- Moving
- Losing employer coverage
- Loss of Medicaid
- Permanent relocation
Most Special Enrollment Periods last 60 days before or after the qualifying event.
July – September
Excellent time to prepare for Open Enrollment.
This is when we recommend clients:
- Review current health insurance usage
- Update prescription lists
- Confirm physician preferences
- Estimate household income for subsidy eligibility
- Compare plan options before enrollment opens
October
Medicare Annual Enrollment Begins
October 15 marks the beginning of Medicare Annual Enrollment (AEP).
This is one of the busiest times of year for licensed Medicare brokers.
November
Marketplace Open Enrollment begins on November 1 for most HealthCare.gov states, including Florida.
This is your opportunity to:
- Enroll in Marketplace coverage
- Change Marketplace plans
- Renew existing coverage
- Update subsidy information
December
Several important deadlines occur during December.
December 15
Typically the last day to enroll for January 1 Marketplace coverage through HealthCare.gov.
December 7
Medicare Annual Enrollment ends.
Changes made during Medicare AEP become effective January 1.
Medicare Enrollment Calendar
Many Floridians mistakenly believe Medicare only has one enrollment period.
In reality, there are several.
Initial Enrollment Period (IEP)
Your Initial Enrollment Period lasts seven months:
- Three months before turning 65
- Your birthday month
- Three months after your birthday month
This is often your best opportunity to enroll without unnecessary delays.
Medicare Annual Enrollment Period (AEP)
October 15 – December 7
You may:
- Change Medicare Advantage plans
- Join Medicare Advantage
- Return to Original Medicare
- Change Part D prescription drug plans
Coverage begins January 1.
Medicare Advantage Open Enrollment
January 1 – March 31
If you already have Medicare Advantage you may:
- Switch to another Medicare Advantage plan
- Return to Original Medicare
- Add Part D if eligible
This period is only available to current Medicare Advantage members.
Special Enrollment Periods (SEP)
One of the biggest misconceptions is that people must wait until Open Enrollment.
Not true.
You may qualify for a Special Enrollment Period if you experience certain life events.
Common qualifying events include:
- Marriage
- Divorce
- Birth of a child
- Adoption
- Moving to a new ZIP code or county
- Losing employer-sponsored coverage
- Turning 26 and aging off a parent’s plan
- Loss of Medicaid or CHIP
- Permanent relocation
- Certain changes in household income
Most Marketplace SEPs provide a 60-day enrollment window.
Employer Health Insurance Open Enrollment
Employer plans have their own enrollment calendars.
Most employers schedule Open Enrollment between:
- September
- October
- November
However, every employer chooses its own dates.
If you’re offered employer coverage, review:
- Monthly premium
- Deductible
- Prescription benefits
- Specialist copays
- Network hospitals
- Family coverage costs
Why Reviewing Your Coverage Every Year Matters
Many people assume keeping the same health insurance plan is the easiest option.
Unfortunately, plans change every year.
Changes may include:
- Monthly premiums
- Deductibles
- Copays
- Prescription formularies
- Provider networks
- Hospital participation
- Out-of-pocket maximums
Even if your premium stays the same, your doctors or medications may no longer be covered the way they were last year.
