How to Choose the Right Group Health Plan

Choosing the right group health plan is one of the most consequential decisions a business owner makes each year — not because the choice is made once and forgotten, but because it repeats annually and compounds. The wrong structure means overpaying a carrier for a plan designed primarily to protect the insurer’s profitability rather than the employer’s budget. The right structure means owning the financial outcome of your group’s actual health experience, keeping the surplus when your team has a good year, and accessing the data that tells you where costs are actually going. Most business owners default to fully insured group health plans out of familiarity and simplicity, never learning that a structurally superior alternative has existed for decades and is now accessible to groups as small as five employees. That alternative is level-funded group health insurance — a hybrid model that combines the cost predictability employers want with the data transparency, plan flexibility, and year-end refund potential that fully insured plans categorically cannot offer.

The group health decision begins with understanding that not all plan structures are created equal — and that the default option presented by a single carrier or a captive agent almost never represents the best available outcome. At Diversified Insurance Brokers, Jason Stolz, CLTC, CRPC, DIA, CAA, works with businesses across all fifty states to evaluate the full spectrum of group health plan structures, from fully insured to level-funded to self-funded, and design the approach that generates the best combination of coverage quality, employee experience, and long-term cost management for each employer’s specific workforce and budget profile. The right group health plan is not the cheapest plan — it is the plan structure that gives you the greatest control over what you pay and what you get for it.

The Three Group Health Plan Structures: What Each One Actually Means

Before evaluating which group health plan structure is right for a specific business, every employer needs a clear understanding of what the three primary funding models actually are — because the differences are structural and consequential, not cosmetic. The funding model determines who bears the financial risk of your employees’ health claims, who keeps the money when claims run low, and who has access to the data that drives the plan’s real cost over time.

A fully insured group health plan is the traditional model. The employer pays a fixed monthly premium to an insurance carrier, and in exchange the carrier assumes all financial responsibility for employee health claims. If your group has an excellent year — minimal hospitalizations, few specialist visits, low prescription spend — the carrier keeps every dollar of unused premium as profit. The employer receives nothing back. The carrier’s renewal quote the following year reflects market pricing, community rating trends, and its own actuarial assumptions, not your group’s actual claim performance. This is the model most business owners are familiar with, and it has one significant structural flaw: it permanently transfers the financial benefit of a healthy workforce to the carrier while leaving the employer exposed to consistent annual premium increases regardless of how well their group actually performed.

A self-funded group health plan sits at the opposite end of the spectrum. The employer directly pays all employee health claims as they are incurred, retaining full financial responsibility for the group’s medical costs. Stop-loss insurance protects against catastrophic individual claims (specific stop-loss) and against aggregate claims that exceed a defined annual threshold (aggregate stop-loss). Self-funding provides maximum transparency and maximum savings potential for groups with favorable claim histories, but it also carries meaningful cash flow risk for smaller employers and requires more sophisticated plan management through a Third Party Administrator (TPA). Our resource on what self-funded group health insurance is covers the mechanics of this model in detail, and the companion page on the pros and cons of self-funded group health is worth reviewing before evaluating whether a group is ready for that level of risk assumption.

Level-funded group health insurance is the hybrid that delivers the best attributes of both models without requiring the scale or risk tolerance that full self-funding demands. It is the structure that the majority of well-informed employers with healthy workforces should be on — and the fact that it remains underutilized reflects a gap in how group health insurance is typically sold, not a gap in its value.

How Level Funding Works: The Mechanics That Make It Superior

In a level-funded plan, the employer pays a fixed monthly amount — predictable and budget-friendly, just like a fully insured premium. That fixed payment is divided into three components: a claims fund allocation (the estimated cost of employee medical claims divided across twelve monthly installments), a stop-loss insurance premium (which protects the employer if claims exceed expectations), and an administrative services fee paid to the TPA or carrier managing the plan. The employer knows exactly what they are paying each month, and that number does not fluctuate during the plan year regardless of how many claims are filed.

At the end of the plan year, the surplus calculation occurs — and this is where level funding fundamentally parts ways with fully insured coverage. If actual employee claims were lower than the funded claims budget, the employer receives a refund of the unused claims fund balance. In a fully insured plan, that same surplus would belong to the carrier. In a level-funded plan, it belongs to the employer. This refund potential — which can range from modest credits to substantial checks depending on how well the group performed — is the most direct financial advantage of level funding, and it represents real money that employers on fully insured plans surrender every year without realizing it. According to UnitedHealthcare data, employers on level-funded structures paid an average of approximately nineteen percent less than comparable fully insured groups. That gap represents the combined effect of risk-based underwriting, exemption from certain state premium taxes, and refund potential that fully insured pricing structurally excludes.

The stop-loss insurance embedded in the level-funded structure is what makes this model accessible and practical for small and mid-size employers who cannot absorb catastrophic claim exposure. Specific stop-loss coverage protects against any individual employee’s claims exceeding a defined threshold — commonly $20,000 to $50,000 per person — ensuring that a single serious illness or injury cannot devastate the employer’s financial position. Aggregate stop-loss coverage provides a ceiling on the group’s total annual claims, protecting against the scenario where multiple employees have high-cost health events simultaneously. The mechanics of how this protection works are covered in detail through our resource on understanding stop-loss insurance in level-funded plans. Taken together, the fixed monthly structure and the stop-loss protection create a model that is genuinely predictable on the cost side while genuinely rewarding on the performance side — a combination that fully insured plans cannot replicate. The comprehensive explanation of all the financial advantages is available through our resource on why group level funding works.

Level Funded vs. Fully Insured: Head-to-Head Comparison

The Claims Data Advantage: Why Transparency Changes Everything

One of the most underappreciated advantages of level-funded group health insurance is not the refund potential — it is the claims data. When a business operates on a fully insured plan, the carrier holds the claims data and is under no obligation to share meaningful utilization information with the employer. You receive a renewal quote and an aggregate rate increase, but you rarely learn which cost categories drove the increase, whether it was prescription spend, specialist visits, or emergency room utilization, or whether specific benefit design changes could have redirected employees toward more cost-effective care pathways. You are, in effect, managing a major expense line with no information about what is driving it.

A level-funded plan fundamentally changes this dynamic. Because the employer is the plan sponsor under ERISA, they have access to detailed monthly claims reports showing utilization patterns, cost drivers, high-cost claimant trends (within HIPAA privacy rules), prescription spend by category, and emergency versus preventive care ratios. This data is not just interesting — it is actionable. An employer who learns that emergency room visits are a disproportionate cost driver can respond with nurse hotline programs that redirect after-hours care. An employer who sees high prescription costs in a specific therapeutic category can work with the TPA to implement formulary management or alternative sourcing strategies. The claims data transparency that level funding provides is what enables employers to actually manage their health plan as a business asset rather than simply receiving a bill from a carrier each month.

According to research from the benefits consulting community, level-funded plans grew from representing approximately seven percent of small-firm coverage to thirty-seven percent of small-firm coverage between 2019 and 2025, according to Kaiser Family Foundation Employer Health Benefits Survey data. That adoption curve reflects a genuine market recognition that the transparency and refund structure of level funding delivers superior value for employers who take the time to understand it. For most well-run businesses with reasonably healthy workforces, level funding is not an advanced or exotic option — it is the right foundational structure, and fully insured coverage is what they should be moving away from. Our resources on the tax benefits of level-funded health insurance and whether small groups can get health insurance refunds provide the financial detail that supports this shift.

Who Level Funding Works Best For — and When Fully Insured Still Makes Sense

Level-funded group health insurance is not the right structure for every employer in every situation, and honest guidance requires acknowledging when fully insured coverage is the more appropriate choice. Level funding produces its strongest results for employers with workforces that are relatively young and healthy, groups with low historical claims utilization, businesses whose owners are motivated to engage with their claims data and make plan management decisions throughout the year, and companies that have experienced repeated renewal increases on fully insured plans without any corresponding improvement in coverage quality. For these groups — and they represent the majority of small to mid-size businesses with functioning wellness cultures and moderate healthcare consumption — level funding is structurally superior to fully insured coverage on both cost and transparency grounds.

Fully insured coverage remains the more appropriate choice for certain specific situations. Groups with employees who have known chronic conditions requiring predictably high ongoing treatment costs may find that level-funded underwriting produces premiums that are not competitive with community-rated fully insured options, because level-funded pricing reflects the actual health risk of the specific group. Very small groups of two or three employees, where a single high-cost claim can exceed the entire claims fund and create significant stop-loss complications, may find the administrative and financial predictability of fully insured coverage more practical. Groups where the employer has no bandwidth for plan management engagement and simply needs a set-and-forget solution may also find fully insured coverage operationally simpler. In these cases, fully insured plans serve as a reasonable fallback — but they should be the fallback, not the default starting point. Our resource on group health insurance cost for small business helps employers understand how level-funded and fully insured pricing compares for groups of various sizes.

Level Funding and the Self-Employed: A Frequently Overlooked Opportunity

One of the most common misconceptions about level-funded group health plans is that they are only available to businesses with traditional W-2 employee populations. In fact, some level-funded structures are available to self-employed individuals and businesses with non-traditional workforce compositions. Understanding whether 1099 contractors can access group level funding is important for businesses that rely heavily on independent contractors or have mixed W-2 and 1099 workforces. The eligibility rules vary by carrier and state, but the opportunity exists in more situations than most business owners assume. For self-employed individuals without any employees, separate pathways for getting group health insurance as a self-employed person exist outside the traditional level-funded structure, though the financial logic of group-style coverage often applies across both contexts.

The tax treatment of level-funded plan contributions also merits attention for self-employed business owners and S-corporation owners who fund their own health coverage. Because level-funded plans are ERISA plans — not insurance contracts subject to state regulation — they carry different tax characteristics than fully insured premiums in certain contexts. Our resource on level-funded health insurance tax benefits covers how employers can deduct their level-funded contributions, how surplus refunds are treated for tax purposes, and how the ERISA status of the plan affects compliance obligations. For ACA-compliant alternatives to traditional group structures, our resource on ACA alternatives for company healthcare covers the full landscape of options beyond the standard carrier marketplace.

The Group Health Decision by Business Size

The right group health plan structure varies with employer size, not because the fundamental logic changes, but because the available options and the risk tolerance appropriate for each size bracket differ meaningfully. For very small employers — groups of two to ten employees — level funding is available from select carriers and offers meaningful advantages over fully insured community-rated plans for groups with healthy demographics. Our resources on group health insurance for a two-person business and group health insurance for ten employees address the specific options and minimum participation requirements at the smallest end of the market. For groups between twenty and fifty employees, level funding typically becomes fully competitive with fully insured pricing for healthy groups and often demonstrably cheaper on a net-of-refund basis when claims performance is favorable. Our resources on group health insurance for twenty employees, thirty employees, and fifty employees cover the size-specific considerations in detail.

For larger employers with fifty to one hundred or more employees, level funding transitions naturally toward fuller self-funding territory where the employer’s statistical pool is large enough to make direct claims management financially meaningful. Group health insurance for one hundred employees covers the funding structure and plan design options for mid-market employers who have outgrown the small group market but have not yet built the internal infrastructure for full self-funding. Industry-specific employer groups — law firms, construction companies, physician practices, accounting firms, and consulting firms — each carry distinct workforce demographics and claims utilization patterns that affect level-funded pricing significantly. Our industry-specific resources on group health for law firms, group health for construction firms, group health for physician practices, and group health for consulting firms help employers in those sectors understand how their workforce profile maps to specific plan structures.

Beyond the Medical Benefit: Building a Complete Employee Benefits Package

The group health plan is the anchor benefit that drives enrollment and employee satisfaction, but a complete employee benefits package integrates several additional coverages that protect employees and the business more comprehensively. Group life insurance provides a death benefit to employee families at a fraction of individual market cost, typically with guaranteed issue provisions that eliminate underwriting for eligible employees. Group long-term care insurance addresses the risk of extended nursing or home care needs that health insurance and Medicare do not adequately cover, at group pricing that substantially undercuts individual LTC premiums. Dental and vision coverage — available through our resource on dental and vision insurance options — rounds out the benefit package in a way that employees value highly even when the employer contribution is modest.

Disability income protection is among the most frequently overlooked gaps in employee benefit packages. Disability income insurance for key person employees and guaranteed issue group disability insurance provide income replacement when employees cannot work due to illness or injury — a risk that statistics consistently show is far more common during working years than premature death. An employer who invests in a well-structured level-funded medical plan and then leaves disability, life, and dental coverage unaddressed has built an incomplete benefits architecture. The most competitive employers in the labor market understand that the total benefits package — not the medical plan alone — determines their ability to recruit and retain quality employees. Working with an independent group health broker who can design and manage the full benefits package rather than a single product line produces the most coherent and cost-effective result.

The Independent Broker Advantage in Group Health Insurance

The same structural dynamic that makes independent broker access valuable in life insurance and annuity markets applies with equal force in group health insurance. A captive agent representing a single carrier presents one funding structure at one price point, evaluated through that carrier’s proprietary lens. An independent broker who works with multiple level-funded carriers, fully insured carriers, and TPA networks can run a genuine cross-market comparison that identifies which structure — and which carrier within that structure — produces the optimal combination of coverage quality, cost, and refund potential for a specific group’s demographics and healthcare needs.

For employers who already have a group health plan and want to know whether they are on the best available structure, a second opinion on their existing group health insurance quote from an independent broker frequently reveals that significant savings are available through a level-funded restructuring that their current broker has never proposed. Our team at Diversified Insurance Brokers approaches every group health engagement by first determining whether level funding is appropriate — and if so, running a market comparison across multiple level-funded carriers to identify the most competitive option before presenting any recommendation. The resource on why working with an independent group health insurance broker matters explains this process in detail, and the resource on how to get the best group health insurance rates covers the specific strategies that independent comparison produces in competitive outcomes. For employers just beginning this process, our resource on how to set up group health insurance for employees provides the foundational process from first evaluation through first plan effective date.
