How to Prepare for Open Enrollment in Florida

By the Florida Plan Finder Team · Licensed Florida Health Insurance Producer · NPN #21249133 · Last Updated: April 8, 2026

Open enrollment is the annual window when Florida residents can enroll in or change their ACA marketplace health insurance plans through healthcare.gov. While the enrollment process itself is straightforward, the decisions you make during this period have a direct impact on your healthcare costs and access for the entire upcoming year. Preparation is the difference between choosing the right plan and realizing in March that your doctor is out of network or your medication is not on formulary.

Florida leads the nation in ACA marketplace enrollment. According to data from the Centers for Medicare and Medicaid Services (CMS), more than 4 million Floridians selected marketplace plans for the 2026 plan year. With over a dozen carriers competing in many Florida counties, there are more options — and more potential for confusion — than in almost any other state. This guide walks you through exactly how to prepare so you can make the best decision during open enrollment.

Know the Open Enrollment Timeline

The open enrollment period for ACA marketplace plans is set by the federal government. Florida uses the federal marketplace at healthcare.gov (Florida does not operate its own state exchange). The typical timeline is:

Outside of open enrollment, you can only enroll or switch plans if you qualify for a Special Enrollment Period (SEP) triggered by a qualifying life event such as losing coverage, getting married, having a baby, or moving to a new area.

Step 1: Gather Your Documents and Information

Before you log in to healthcare.gov or call an agent, assemble the following:

• Social Security numbers for every household member who will be on the plan.
• Estimated household income for the upcoming year. The marketplace uses your projected annual income — not last year's tax return — to calculate your Advance Premium Tax Credit (APTC). If you are self-employed or have variable income, estimate as accurately as possible. KFF's subsidy calculator is a useful tool for running scenarios.
• Your current plan's Summary of Benefits and Coverage (SBC). If you are renewing, your insurer sends this document before open enrollment. It details your current premiums, deductible, copays, coinsurance, and out-of-pocket maximum. Use it as a baseline for comparison.
• A list of your doctors, specialists, and hospitals. Write down the names and, if possible, the National Provider Identifier (NPI) numbers of every provider you want to keep seeing. You will need this to check network directories.
• A list of your prescription medications. Include the drug name, dosage, and frequency. You will use this to check each plan's formulary (the list of covered drugs) and see what tier your medications fall under.
• Immigration documents (if applicable) for household members who are not U.S. citizens.
• Information about employer-sponsored coverage available to you or your spouse, even if you do not plan to use it. The marketplace application asks about this.

Step 2: Review Your Current Plan's Changes

If you already have a marketplace plan, do not assume it will stay the same next year. Insurers file new rates and plan designs annually with the Florida Office of Insurance Regulation. Common changes include:

• Premium increases or decreases. Your premium may go up even if your plan design stays identical. Your subsidy amount may also change, which affects your net premium.
• Network changes. Providers and hospitals enter and leave carrier networks every year. A doctor who was in-network this year may not be next year.
• Formulary changes. Drugs can be moved to different tiers (affecting your copay or coinsurance) or removed from the formulary entirely.
• Plan discontinuation. Your specific plan may be discontinued. If so, your carrier will auto-enroll you into a similar plan — but "similar" does not mean identical. Review the replacement carefully.

Your insurer is required to send you a notice before open enrollment describing any changes. Read it. If you cannot find it, call the carrier or check your healthcare.gov account for plan renewal information.

Step 3: Estimate Your Subsidy

Most Florida marketplace enrollees receive financial assistance. According to CMS data, roughly 90 percent of Florida marketplace enrollees receive APTC subsidies that reduce their monthly premiums. Your subsidy amount depends on your household income relative to the federal poverty level (FPL), your household size, and the cost of the benchmark Silver plan in your area.

Use the KFF Health Insurance Marketplace Calculator or healthcare.gov's window-shopping tool to estimate your subsidy before you formally apply. This gives you a realistic picture of what you will actually pay each month. Keep in mind that if your income changes during the year, you should update your marketplace application — otherwise you may owe money back at tax time or miss out on a larger subsidy.

If your income falls between 100 and 250 percent of FPL, you may also qualify for Cost-Sharing Reductions (CSR), which lower your deductible, copays, and out-of-pocket maximum. CSRs are only available on Silver plans. This is a major reason to look closely at Silver plans even if a Bronze plan appears cheaper at first glance.

Step 4: Compare Plans on Total Cost, Not Just Premium

One of the most consequential preparation steps is understanding that monthly premium is only one piece of your total annual healthcare cost. A plan with a low premium and a high deductible may cost you far more overall than a plan with a slightly higher premium and lower deductible — especially if you use healthcare regularly.

When comparing plans, calculate the estimated total annual cost:

• Annual premiums (monthly premium multiplied by 12, after subsidy)
• Expected deductible spending based on your typical healthcare usage
• Copays and coinsurance for your regular doctor visits, specialist visits, and prescriptions
• Out-of-pocket maximum — the worst-case annual spending cap. If you anticipate a surgery, hospitalization, or expensive treatment, the out-of-pocket maximum becomes the most important number.

Healthcare.gov allows you to enter your doctors and prescriptions during the plan comparison process, which helps estimate your total costs under each plan. Use this feature — it is far more informative than looking at premiums alone.

Step 5: Check Networks and Formularies

Florida's marketplace has a wide range of plan types — HMO, PPO, EPO — each with different network rules. Before you commit to a plan:

• Search the carrier's provider directory for the specific plan (not just the carrier name — a carrier may have multiple networks).
• Confirm your medications are covered by checking the plan's formulary, available on the carrier's website or through healthcare.gov plan details.
• Call your doctor's office to double-check they accept the specific plan for the upcoming year. Online directories can be outdated.

Step 6: Do Not Auto-Renew Without Reviewing

If you are already enrolled and take no action during open enrollment, the marketplace will auto-renew you into the same plan (or a similar one if yours was discontinued). This is convenient but frequently costly. According to research published by KFF, consumers who actively shop and switch plans during open enrollment often save hundreds of dollars per year compared to those who passively auto-renew.

The competitive landscape in Florida shifts annually. A plan that was the best value last year may not be this year, and a new carrier entry could offer better coverage at a lower price. Treat every open enrollment as a fresh decision.

Working with a Licensed Agent or Navigator

You do not have to navigate open enrollment alone. Licensed health insurance agents and certified navigators can help you compare plans, estimate subsidies, check networks, and complete the application — all at no cost to you. Agents are compensated by the insurance carriers, so their help does not add anything to your premium.

In Florida, agents are particularly useful because of the sheer number of plan options. Many Florida counties have 10 or more carriers offering plans, each with multiple metal levels and plan types. An experienced agent who understands the local market can narrow your choices quickly based on your specific doctors, medications, and budget.
