Winning Open Enrollment: How to Boost Employee Engagement and Lower Renewal Costs

A Strategic Guide for HR Leaders and Business Owners

Nearly half of all Americans struggle to afford healthcare, and nearly one-third feel completely overwhelmed by medical bills and complex billing processes. As group health insurance renewal rates continue to escalate, employers face a dual challenge

: how to drive active participation during Open Enrollment while simultaneously keeping healthcare costs manageable for both the business and its workforce.

These two challenges are deeply interconnected. When employees are disengaged during enrollment, they frequently end up in inappropriate plans, underutilize cost-saving features, and make expensive care choices throughout the year.

Here is a practical guide on how to solve both sides of the equation.

Part 1: How to Increase Employee Open Enrollment Participation Rates

Low participation during Open Enrollment is rarely caused by employee indifference; more often, it stems from health literacy confusion and process friction. Implementing strategic adjustments can turn passive enrollment into an engaging experience.

1. Require Active Re-Enrollment (Eliminate Auto-Rollover)

When plans automatically roll over from year to year, employees default to passive behavior. Studies show that while 76% of employees stay with their plan out of satisfaction, a notable portion stay simply because they are confused, missed the enrollment window, or didn't know how to make changes.

By requiring active re-enrollment every year, employers prompt workers to re-evaluate their current medical needs, preventing costly over- or under-coverage.

2. Shift from Passive Emails to Interactive Communication

Emails are easy to send, but fewer than half of employees find email updates helpful

when navigating health insurance. In contrast, 80% of employees report that in-person or direct conversations are extremely helpful.

To maximize participation:

• Host brief, interactive presentation sessions (virtual or in-person) with dedicated Q&A time.

• Provide one-on-one consultation slots with HR or benefit advisors.

• Send multi-channel reminders across messaging platforms, digital portals, and physical flyers.

3. Demystify Healthcare Jargon

Basic health insurance terms remain confusing to many workers—studies indicate that 10% of employees do not know what a premium is, and 8% are unsure of the difference between "in-network" and "out-of-network".

When presenting benefits options:

• Frame options in terms of exact per-paycheck payroll deductions alongside total monthly contributions.

• Clearly explain how employer-sponsored health options interact with Marketplace options, specifically noting how affordable employer coverage impacts eligibility for Marketplace tax credits.

• Provide clear, side-by-side cost comparisons for common scenarios (e.g., routine doctor visits vs. urgent care).

4. Incentivize Early Action and Digital Tool Engagement

Digital adoption programs can encourage timely completion. Leveraging digital member engagement programs—such as small incentives for completing enrollment forms early or setting up automated premium payments—builds consistent engagement habits.

Part 2: How Employers Can Reduce Group Health Insurance Renewal Costs

Containing group health insurance renewal costs requires moving beyond standard fully insured renewals and focusing on plan structure, funding mechanics, and long-term employee utilization patterns.

1. Explore Alternative Funding Models (Level-Funded Plans)

Traditional fully insured health plans require employers to pay fixed premiums where the insurer retains all unused claim funds as profit. Transitioning to level-funded arrangements offers a predictable monthly payment while allowing employers to receive refunds of unused claim funds at the end of the plan year.

Key advantages of level-funded solutions include:

• Unused Claim Refunds: If claims are lower than projected, 50% to 100% of unused claim account funds can be returned to the employer.

• Stop-Loss Protection: Cap maximum exposure so cash flow remains predictable throughout the year.

• Flexible Carrier Networks: Access to broad national PPO networks or high-performance narrow networks tailored to local demographics.

2. Optimize Network Selection and Consider Hybrid Designs

Network design significantly influences annual insurance renewal rates. Employers can evaluate alternative network structures to match employee needs while controlling costs:

• Tiered & Narrow Networks: Offering focused local provider networks alongside broad PPOs gives budget-conscious employees lower premium entry points.

• Reference-Based Pricing (RBP) Hybrids: Blending standard PPO networks for primary care with RBP for facility claims can yield substantial savings over traditional commercial network rates.

3. Educate Employees as Health Care Consumers

Up to 26% of employees use urgent care clinics for non-emergencies, and 7% rely on emergency rooms for routine care, driving up overall group plan claims. In addition, only 31% consistently check if a provider is in-network before receiving care.

Employers can mitigate unnecessary claim costs by educating employees to:

• Utilize Primary Care Physicians (PCPs) or $0 copay virtual care platforms for non-emergency conditions.

• Always verify in-network status prior to scheduled appointments.

• Choose lower-cost generic alternatives for prescription medications.

4. Introduce High-Deductible Health Plans (HDHPs) Paired with HSAs

High-Deductible Health Plans reduce monthly premium costs for both the employer and employee. When paired with Health Savings Accounts (HSAs), employees can contribute pre-tax dollars toward qualified medical expenses, lowering their tax burden while creating a personal safety net for future healthcare needs.

Executive Strategy Matrix

Initiative	Strategic Goal	Primary Impact
Mandatory Active Re-Enrollment	Increase OE Participation	Prevents default choices, rightsizes coverage, and improves employee awareness.
In-Person & Direct Consultations	Increase OE Participation	Achieves up to 80% communication effectiveness vs <50% for passive email campaigns.
Level-Funded Health Plans	Reduce Renewal Costs	Caps monthly risk while returning unused claim funds back to the business.
Consumer Education Programs	Reduce Renewal Costs	Steers routine care from ER/Urgent Care to PCPs and virtual visits, lowering group claims.
HDHP + HSA Bundling	Reduce Renewal Costs	Decreases baseline group premiums while offering employees tax-advantaged savings.

Summary: Building a Sustainable Benefits Strategy

Increasing Open Enrollment participation and controlling group health insurance costs share a single foundation: education and proactive plan design. By eliminating passive enrollments, engaging employees through direct communication, and exploring flexible level-funded plan structures, businesses can effectively manage annual renewal costs while delivering health benefits employees understand and value.
