Open enrollment is your annual chance to sign up for, change, or drop employer-sponsored health insurance and other benefits. For most people with job-based coverage, it falls in the fall — typically October to December — with new coverage starting January 1. But your employer sets the exact dates, so check with HR. Miss that window and you're locked in until next year, unless you have a qualifying life event like marriage, a baby, or losing other coverage. That triggers a Special Enrollment Period.
Important Deadlines and Timelines
But some deadlines are set at the federal and market level. Knowing these helps you plan — whether you're enrolling through an employer, the Marketplace, or Medicare.
Employer-Sponsored Plan Deadlines
Most companies finalize their plans and premiums in Q3 and announce open enrollment dates in early Q4. The window is usually 2-4 weeks. So take the deadline seriously. Do nothing, and you'll likely be auto-re-enrolled. But in some cases, you could lose coverage entirely.
Health Insurance Marketplace (ACA) Deadlines
If you're buying through Healthcare.gov or a state exchange, the open enrollment period runs from November 1 to January 15. Want coverage starting January 1? You need to enroll by December 15. And some state exchanges—like California, New York, Colorado—have extended deadlines.
Medicare Annual Enrollment Period
The Annual Enrollment Period (AEP) runs from October 15 to December 7 each year. Changes kick in January 1. It's your chance to switch plans, change Part D coverage, or move between Original Medicare and Medicare Advantage.
What Changes Can You Make During Open Enrollment?
Open enrollment is your chance to rethink your benefits. Here's what you can usually change:
- Enrolling in or Waiving Health Insurance: Signing up for the first time or opting out if you have alternative coverage.
- Switching Plan Types: Moving from a PPO to an HMO, a High-Deductible Health Plan (HDHP) to a more traditional plan, or vice-versa.
- Adding or Dropping Dependents: Covering a new spouse or child, or removing dependents who now have their own coverage.
- Electing Supplemental Benefits: Signing up for dental, vision, disability, or life insurance.
- Contributing to Tax-Advantaged Accounts: Setting or changing your contributions to a Health Savings Account (HSA), Flexible Spending Account (FSA), or Dependent Care FSA.
How to Prepare for Open Enrollment
Don't wait for the enrollment packet to arrive. Preparing early ensures you pick the right coverage and maximize your benefits.
- Audit Your Previous Year's Healthcare Usage: Review how often you visited doctors, what prescriptions you filled, and any anticipated changes for the coming year (like planned surgery or having a baby).
- Evaluate Total Costs, Not Just Premiums: Compare deductibles, copays, coinsurance, and out-of-pocket maximums across plan options. The cheapest monthly premium may cost you more annually.
- Check Provider and Pharmacy Networks: Ensure your preferred doctors, hospitals, and medications are covered under any new plan you are considering.
- Maximize Linked Benefits and Incentives: Investigate if your employer offers programs like WellthCare, which turns preventive health actions into automatic retirement contributions and spendable store dollars. Aligning your health plan choice with such programs can create significant added value.
- Complete All Elections by the Deadline: Submit your elections through the HR portal or with your benefits administrator before the stated deadline. Keep a confirmation for your records.
Open enrollment is more than an administrative task — it's a chance to plan your finances and health. WellthCare, the first Health-to-Wealth Benefit System, works alongside your existing health plan and gets used first, rewarding every preventive action with store dollars and automatic retirement contributions. Know the deadlines, evaluate your options, and you'll get coverage that protects your well-being and builds your wealth throughout the coming year.
