Offering health benefits is not only a strategic move for attracting and retaining talent but also for fostering a healthy, productive workforce. Whether you’re an employer aiming to provide comprehensive coverage or an individual exploring your insurance options, understanding the leading insurers and innovative benefit structures is essential. This overview discusses the dominant players in the industry, how much revenue they generate through premiums, and why emerging benefit models are gaining popularity.

What Is Traditional Group Health Insurance?

When comparing health insurers, many organizations initially consider group health plans. These plans involve employers selecting a medical coverage package to provide to employees and their dependents at reduced rates. Typically, insurers require a minimum participation rate—often around 70%—for a group to qualify. If the threshold isn’t met, the organization may not be eligible for coverage through that insurer.

Insurance carriers offer various plan types, including:

  • Health Maintenance Organizations (HMOs)
  • Preferred Provider Organizations (PPOs)
  • Exclusive Provider Organizations (EPOs)
  • Point-of-Service (POS) Plans

Employees enrolled in these plans usually pay a portion of the premium and are responsible for meeting an annual deductible before the insurance begins sharing costs for medical claims. Employers can purchase these policies directly from insurers, through licensed agents, or brokers. Small businesses in many states also have the option of buying plans via the Small Business Health Options (SHOP) marketplace, which may qualify them for the Small Business Health Care Tax Credit, reducing overall costs.

The cost of group health insurance varies depending on numerous factors, but generally, premiums tend to increase each year. According to the Kaiser Family Foundation (KFF), the average annual premium in 2024 was approximately $8,951 for self-only coverage and $25,572 for family coverage. Employers contributed an average of $7,584 toward self-only plans and $19,276 toward family plans. While group coverage remains a preferred choice for many, the high costs can be prohibitive for smaller enterprises.

Alternatively, individuals can purchase their own insurance policies directly through the Health Insurance Marketplace, or through state exchanges. Many of the same carriers offer these plans, providing flexibility without the administrative burden of traditional group plans. Employers can also offer stand-alone HRAs to reimburse employees for health expenses, offering a more adaptable benefits approach.

In 2023, U.S. health insurers collectively earned approximately $1.08 trillion in net premiums, marking an 8% increase from 2022. This growth demonstrates ongoing demand for health coverage amid rising healthcare costs and inflation.

UnitedHealth Group, the industry leader, generated about $248 billion in premiums, underscoring its dominant position.

Benefits of HRAs and Stipends for Small Businesses

With premium costs continually rising, small and medium-sized companies often find traditional group plans financially challenging. Meeting minimum participation requirements and managing administrative burdens can deter small employers from offering valuable health benefits. Fortunately, alternative strategies like HRAs (Health Reimbursement Arrangements) and stipends provide more flexible, budget-friendly options.

An HRA allows employers to reimburse employees, tax-free, for qualified medical expenses or insurance premiums. These plans enable customization, allowing businesses to set monthly allowances, which employees can use for various healthcare costs. For example, the individual coverage HRA (ICHRA) permits companies of all sizes to reimburse employees for their private health insurance premiums without the need for group coverage.

Similarly, the qualified small employer HRA (QSEHRA) is tailored for smaller firms with fewer than 50 employees, offering a maximum allowance that employees can allocate toward their preferred insurance plans and out-of-pocket expenses. These arrangements are particularly advantageous for startups and small businesses aiming to provide meaningful benefits without the administrative complexity of traditional plans.

Another option is the integrated HRA, which complements existing group coverage, such as high-deductible health plans. Employers can reimburse employees for deductibles, coinsurance, and other out-of-pocket expenses, giving staff greater flexibility.

Lastly, taxable stipends are straightforward to implement and offer employees a fixed amount of money to cover medical costs, including supplemental dental and vision plans. Although stipends are considered taxable wages, they provide employees with the freedom to allocate funds as they see fit. However, employers should note that stipends alone do not fulfill employer mandate requirements under the Affordable Care Act (ACA).
