Two Paths to Coverage: The Level Funded Plan vs. Fully Insured

Choosing between a level funded plan and a fully insured model is one of the most consequential funding decisions an employer can make before their next renewal. When an employer sponsors group health insurance, the first structural decision isn’t which carrier to use or which plan design to offer — it’s how to fund the coverage. That funding structure determines how costs flow, who bears risk, what data you can access, and how much control you have over what happens at renewal.

Most employers default to fully insured. It’s familiar, administratively simple, and the default offering from most brokers. But level funded health plans have grown substantially in availability and adoption, and for many employer groups, the comparison clearly favors level funding.

This guide breaks down every significant dimension of the level-funded vs. fully insured decision.

The Fundamental Difference: Who Holds the Risk

The core distinction between the two funding structures is risk bearing.

In a fully insured arrangement, the employer transfers all financial risk to the insurance carrier in exchange for a fixed monthly premium. The carrier prices that premium to cover expected claims, administrative costs, stop-loss reserves, and profit margin — for the carrier’s entire book of business, not just your group. When your group has a healthy year, the carrier profits. When claims are high, the carrier absorbs the loss.

In a level funded arrangement, the employer retains the financial risk of their own group’s claims — but that risk is capped by stop-loss insurance purchased as part of the plan structure. The employer pays a fixed monthly amount that funds projected claims, stop-loss protection, and TPA administration. If claims are below projections, the employer receives a surplus refund. If claims exceed projections, stop-loss coverage limits the employer’s additional exposure.

Cost Structure Comparison

Fully insured cost structure:
– One monthly premium payment to the carrier
– Premium includes: claims funding + risk margin + admin + profit
– Employer cannot separate these components or capture savings from favorable claims

Level funded cost structure:
– Monthly payment broken into: claims fund + specific stop-loss + aggregate stop-loss + TPA admin fee
– Each component is transparent and separately tracked
– Year-end surplus refund available if actual claims are below the claims fund projection

The practical implication: fully insured premiums embed a cost of certainty that level funded employers don’t pay. For groups with favorable claims experience, that embedded cost is real money left on the table.

Claims Data and Transparency

This is where the difference between fully insured and level funded is most operationally significant for employers.

Fully insured: Most carriers will not share detailed claims utilization data with employer groups under 50–100 covered lives. The employer receives no visibility into what’s actually driving their costs. At renewal, the carrier presents an increase and the employer has no data to challenge or contextualize it.

Level funded: The TPA provides monthly claims reports that include total claims versus projections, claims by category (medical, pharmacy, specialty, preventive), and tier-level utilization data. This data enables employers to:

Identify cost drivers before renewal
Make mid-year plan design adjustments
Model renewal scenarios using actual data rather than carrier estimates
Hold carriers accountable with specific utilization evidence

For employers who want to actively manage health benefit costs rather than passively absorb carrier decisions, claims transparency is not optional. Level funded is the mechanism that delivers it at groups under 100 lives.

Stop-Loss Protection: Your Safety Net

A common concern with level funded plans is risk exposure. The stop-loss structure answers this concern.

Specific (individual) stop-loss sets a per-person claims threshold — commonly $25,000 to $75,000 per member per year depending on group size. Once a single member’s claims exceed that threshold, the stop-loss carrier pays the remainder. This protects against catastrophic individual claims events.

Aggregate stop-loss sets a total claims cap for the group — typically 115–125% of projected annual claims. If your group’s total claims exceed this cap, the stop-loss carrier pays the excess. This protects against an unexpectedly bad claims year across the group.

The result: level funded employers have a defined, predictable maximum financial exposure — similar in structure to the predictability of a fully insured premium, but with the potential to pay less when claims are favorable.

ACA Compliance Under Both Structures

Both fully insured and level funded plans must satisfy ACA requirements for applicable large employers (50+ FTEs):

Minimum essential coverage (MEC) requirement
Minimum value standard (60% actuarial value)
Affordability requirements (employee contribution ≤ 9.02% of W-2 wages for 2025)
1094-C / 1095-C annual reporting

Level funded plans are self-funded arrangements for ERISA and ACA purposes, which means they are exempt from certain state-mandated benefits. This can be an additional cost advantage in states with expensive mandate requirements — though this benefit is less significant in Texas, which has relatively limited state-level mandates compared to states like New York or California.

Level funded plans do require more formal ERISA plan documentation (Summary Plan Description, wrap document) than fully insured plans. A qualified TPA provides these documents as part of the administrative package.

Which Employers Are Best Suited for Each Option?

Level funded is typically the better fit when:
– Group has 25–150 covered lives
– Workforce skews younger and healthier (lower average age, fewer chronic conditions)
– Employer wants claims data and cost transparency
– Prior years’ claims experience is average or favorable
– Benefits consultant has level funded placement experience

Fully insured is typically the better fit when:
– Group is very small (under 15 covered lives)
– Known high-cost claimants make level funded underwriting difficult or expensive
– Employer strongly prioritizes administrative simplicity
– Industry or workforce characteristics create significant claims volatility
– Group is in a high-growth phase with highly unpredictable enrollment

The Renewal Renewal Dynamic

One of the most significant long-term differences between the two structures plays out at renewal.

Under a fully insured plan, the carrier controls the renewal. They use internal actuarial models, book-of-business trends, and ACA risk adjustment data to set your rate. Your leverage is limited to the ability to shop the market — which helps, but still keeps you in a reactive position.

Under a level funded plan, your renewal is informed by your own claims data. You know what drove utilization. You know your stop-loss performance. You know whether your claims fund was adequate, over-funded, or under-funded. That knowledge gives you genuine negotiating leverage with both your current TPA and competing carriers.

Over a 3–5 year horizon, the compounding effect of annual claims data and renewal leverage is often more financially significant than the year-one cost comparison.

Frequently Asked Questions

Is level funded health insurance the same as self-funded?
Level funded plans are a form of self-funding, but they’re structured differently than traditional self-funded (Administrative Services Only, or ASO) arrangements. Traditional self-funded plans pay claims as incurred with stop-loss protection. Level funded plans set a fixed monthly payment upfront — more similar in cash flow to a fully insured premium — while still providing claims transparency and surplus refund potential. Level funded is often considered “self-funding with training wheels” — a lower-complexity entry point.

Can an employer switch between fully insured and level funded?
Yes, typically at the plan renewal date. The transition requires underwriting review, new plan documentation, and carrier/TPA selection. Your benefits consultant should model the comparison 90–120 days before your renewal to allow adequate time for evaluation and transition.

What is the minimum group size for level funded health insurance?
Many carriers and TPAs offer level funded products starting at 10–15 covered employees. The financial benefits of level funding become more meaningful as group size increases and claims data becomes more statistically credible. Most consultants recommend level funding evaluation for any group with 25 or more covered lives.

How do employees experience the difference between fully insured and level funded?
From an employee perspective, the experience is largely identical. They have the same ID card, provider network access, claims process, and plan design features. The funding structure is a back-office financial mechanism that is invisible to employees during day-to-day plan use.

The Bottom Line on Level-Funded vs. Fully Insured

Fully insured plans offer simplicity and certainty. Level funded plans offer transparency, cost control, and the potential to benefit from your group’s own favorable claims experience.

For most growing employers with reasonably healthy workforces, the expected value of level funding is positive — and the claims visibility alone is worth the transition even before any surplus refund is factored in.
