MillerKnoll Employees Could Face Triple Impact from 2026 Health Insurance Price Increases

Healthcare Provider Update: MillerKnoll offers health insurance coverage through PPO plans with Blue Cross Blue Shield of Michigan. Employees benefit from low deductibles, preventive care at no cost, and access to a broad provider network. The company also provides dental and vision coverage, FSAs, HSAs, and prescription drug benefits through Express Scripts. Additional perks include wellness programs, mental health support, and a 401(k) with employer match 1. MillerKnoll Healthcare costs in the United States are projected to continue rising through 2026, with insurers proposing significant premium increases for Affordable Care Act (ACA) plans. A recent analysis found that ACA insurers are seeking a median premium increase of 15% for 2026, marking the largest hike since 2018. This surge is attributed to factors such as the anticipated expiration of enhanced premium tax credits, rising medical costsincluding expensive medications and increased hospital staysand a shift in the risk pool towards higher-cost enrollees. Without the renewal of enhanced subsidies, out-of-pocket premiums for ACA marketplace enrollees could increase by more than 75% on average. Click here to learn more

In this article, we will discuss:

1. Why group health insurance costs are expected to rise sharply in 2026.

2. How employers may shift health care expenses to employees through plan changes.

3. Key steps individuals can take during open enrollment to manage higher costs.

The cost of group health insurance is expected to rise at the fastest pace in 15 years, ¹  creating significant challenges for both companies and their employees. MillerKnoll employees may soon see higher co-payments, larger deductibles, and greater payroll deductions. Employers across the country are also preparing to make structural adjustments to their health plans, which could mean less prescription drug coverage or tighter provider networks. With Baby Boomers working later into their careers and medical costs continuing to rise, these changes reflect a broader transformation in the American health care system.

According to Brent Wolf, CFP of Wealth Enhancement, “the biggest increase in health insurance costs in over ten years is about to hit both employers and employees. This affects almost everyone and is structural and demographic in nature; it is not just about inflation.”

Factors behind rising prices

While cost hikes in employer-sponsored health insurance have generally been modest, forecasts for 2026 point to a sharp rise. Average benefit costs per employee are expected to grow by over 6.5%, the steepest jump since 2010. ¹  This rise is being driven by several key elements:

• An aging workforce: Many Baby Boomers are working well into their 60s and 70s. Their growing medical needs—from advanced oncology treatments to cardiac care—place heavy cost pressure on employer health plans.

• High-cost claimants: Roughly 20% of employees generate over 80% of health care expenses, ²  concentrating costs and making them hard to manage.

• Medical inflation: New therapies, industry consolidation, and complex billing practices are fueling rising medical inflation.

• Regulatory changes: Recent legislation such as the “One Big Beautiful Bill” adds complexity and unpredictability for employer planning.

• Increased utilization and postponed care: Many delayed care during the pandemic. As people return for elective procedures, overall costs have surged.

Wolf observes, “This is a triple whammy. Employers have few options to control costs, medical costs are climbing, and older workers are using more care.”

Employers’ cost management tactics

Nearly 60% of companies are expected to adjust health plan designs in 2026 to help with rising costs ¹ —a much larger share than in prior years. For MillerKnoll employees, these modifications may translate into a higher out-of-pocket load, particularly if companies pursue cost cutting strategies such as:

• Increased payroll deductions: Premium contributions may go up about 6% to 7%, ¹  leading to larger deductions from wages.

• Higher out-of-pocket costs: Changes to deductibles, copayments, and coinsurance will raise what individuals pay when getting care.

• Narrower provider networks: Employers might limit access to certain doctors or prescription medications.

• Plan design shifts: A move toward high-deductible health plans is expected, placing more load on employees to make cost-conscious choices.

According to Wolf, “Employers may quietly reduce benefits because they don't want to annoy employees with premium hikes.” The result is the same: higher household costs.

Getting ready for enrollment

As open enrollment season approaches, careful planning will be very important. Wolf suggests a few key actions:

• - Track open enrollment dates so you don’t miss your chance to make selections.

• - Review all details beyond the monthly premium, including prescription lists, provider networks, and out-of-pocket maximums.

• - Match coverage with personal health needs—chronic conditions may justify higher premiums, while healthier people might prefer high-deductible plans.

• - Use tax-advantaged accounts like flexible spending account (FSAs) or health savings accounts (HSAs) to help offset costs with pre-tax funds.

• - Take advantage of wellness programs that promote preventive care and healthier lifestyles.

The broader context

The demographic reality of an aging workforce will keep pushing health care costs higher for employers and employees alike. MillerKnoll employees, like others across the workforce, will feel these changes beyond 2026.

Wolf emphasizes, “This is not a one-year story.” The cycle of rising costs will affect employers, employees, and retirees for years to come. Planning ahead, budgeting for cost increases, and making informed enrollment choices will be essential.

In addition, Medicare costs are projected to rise significantly in 2026: the Part B monthly premium is expected to climb 11.6%, from $185 in 2025 to $206.50. ³  Part D premiums are forecast to go up 6%, from $36.78 to $38.99, while deductibles increase to $615. ⁴  The Part B deductible is also set to go up nearly 12%, from $257 to $288. ³

Employer-sponsored plans overall are expected to see employee health benefit costs rise by about 6.5% in 2026, the most rapid climb in 15 years. ¹  For MillerKnoll employees, the combination of higher copays, deductibles, and premiums mirrors the national trend driven by medical inflation, expensive therapies, and regulatory shifts.

An analogy for what lies ahead

Dealing with these changes is much like planning for a road trip where fuel prices suddenly jump, tolls multiply, and detours force you onto costlier routes. The journey still has to happen, but it now demands more foresight, budget planning, and careful choice-making. Employees will need to carefully evaluate their open enrollment options, just as travelers must adapt their maps and decisions to reach their destination under changed conditions.
