Frequently Asked Questions

What is open enrollment?

Open enrollment is the designated annual period during which employees can make changes to their benefits elections, including health insurance, dental, vision, life insurance, and other voluntary benefits. Outside of this window, changes can only be made due to qualifying life events. Open enrollment typically lasts two to four weeks and is mandated by regulations governing employer-sponsored benefit plans.

When should open enrollment planning begin?

Start planning at least four to six months before the enrollment window opens to allow time for plan renewals, vendor negotiations, and communication development. System testing and content preparation should be finalized at least six weeks before enrollment begins. Build a detailed project plan with milestones and assign clear ownership for each deliverable.

How long should the open enrollment period last?

Most organizations offer a two to four week enrollment window, which provides employees sufficient time to review options and make decisions without creating an overly long administrative burden. Some organizations extend to 30 days for complex benefits packages or geographically dispersed workforces. Regardless of length, front-load communications and reminders to avoid a last-day rush.

What is passive enrollment versus active enrollment?

Passive enrollment automatically rolls over an employee's current elections if they take no action during open enrollment, while active enrollment requires every employee to make affirmative elections. Passive enrollment reduces administrative burden but may result in employees staying in suboptimal plans. Active enrollment increases engagement but requires more intensive communication and support.

How do you communicate open enrollment effectively?

Use a multi-channel communication strategy that includes email, intranet, physical mail, text messages, and manager cascades to reach all employees. Start communications at least three weeks before enrollment opens and increase frequency as the deadline approaches. Include clear action items, deadlines, and links to enrollment tools in every communication.

What are the most common open enrollment mistakes?

Common mistakes include starting communication too late, insufficient employee education on plan changes, inadequate system testing, and lack of decision support tools. Other pitfalls include not planning for technology issues during peak enrollment days and failing to audit elections before transmitting to carriers. Conducting a lessons-learned review after each cycle helps prevent recurring mistakes.

How do you handle employees who miss open enrollment?

Employees who miss open enrollment are generally locked into their current elections or default coverage until the next enrollment period or a qualifying life event. Communicate this consequence clearly and repeatedly before and during the enrollment window to minimize missed enrollments. Some organizations make exceptions for documented extenuating circumstances, but this should be handled consistently to avoid precedent issues.

How do you measure open enrollment success?

Track metrics including enrollment completion rates, on-time election percentages, benefits fair or webinar attendance, and help desk inquiry volume. Measure employee satisfaction through a post-enrollment survey and identify pain points for future improvement. Compare carrier file accuracy rates and the number of post-enrollment corrections to assess process quality.
