Fully Insured vs Level-Funded vs Self-Funded Health Plans

Health benefit costs put pressure on employers. That forces a hard question: is there a smarter way to fund your group health plan?

The answer depends on how much financial risk you are willing to carry, how much control you want over plan design, and how clearly you can see your own claims data. Three funding models dominate the market: fully insured, level-funded, and self-funded. Each one handles risk, cash flow, and transparency differently.

A licensed independent agent can explain the distinctions for a South Carolina employer. Any specific recommendation belongs with the licensed agent handling the account.

• You could not absorb a surprise six-figure claim. A fully insured plan puts the risk entirely with the insurance company. That predictability is valuable, especially for very small employers.
• You want steady monthly payments and a chance of money back. For some employers, a level-funded plan may offer more predictable monthly payments while retaining claims-experience risk. Suitability depends on the group.
• You want detailed claims data and more control over plan design. A self-funded plan gives you both, but you carry the claims risk yourself. Most self-funded employers buy stop-loss coverage for that reason.

Fully insured. This is the most familiar setup. Your company pays a fixed monthly premium to an insurance company, and the insurance company pays covered claims under the policy. The insurance company absorbs the claims risk if costs spike. The trade-off is that the premium reflects the insurance company's risk charge, and the employer has less control over the funding mechanics.

Self-funded. This flips the model. The employer pays claims directly out of its own funds, usually with help from a third-party administrator that processes paperwork and manages the network. The employer retains the upside if claims are lower than expected, but also carries the claims risk unless protection is purchased.

Level-funded. Level-funded plans are not fully insured. They combine a fixed monthly payment with an expected-claims component, administrative fees, and stop-loss premiums. Favorable claims experience may produce a surplus credit or refund under the contract. Unfavorable claims experience can affect renewal pricing and terms.

The table below sets out how each model handles payment, risk, and claims data.

What that means for you. A level-funded arrangement can offer more predictability than traditional self-funding, but it does not eliminate claims-experience risk. A self-funded arrangement changes the cost structure, but total cost depends on claims, administration, stop-loss, and contract terms.

Who carries the risk is the core distinction between these three models.

Fully insured. Risk sits entirely with the insurance company. Your premium is your premium, whether your employees file ten claims or ten thousand. That predictability is valuable, especially for very small employers who cannot absorb a surprise six-figure claim.

Self-funded. You carry the claims risk yourself. In a bad year, a handful of expensive hospitalizations or specialty drug prescriptions can blow past your budget. That is why most self-funded employers purchase stop-loss coverage.

Level-funded. The risk is split. The employer is technically self-funded, but the fixed monthly payment and built-in stop-loss create a financial floor and ceiling. Your cash flow looks a lot like a fully insured plan month to month, but you retain the chance of getting money back if claims are favorable.

One thing to keep in mind: self-funded and level-funded arrangements can have different federal and state regulatory treatment from fully insured plans, and the details depend on the arrangement and applicable law. Do not treat this overview as ERISA or legal advice; confirm the requirements for a specific arrangement with Compliance and the employer's advisor.

Stop-loss coverage is what makes self-funding practical for employers who are not Fortune 500 companies. It works as a safety net, reimbursing the employer when claims exceed a set threshold.

There are two types.

• Specific stop-loss reimburses covered claims above a contract threshold for one individual.
• Aggregate stop-loss reimburses covered claims above a contract threshold for the group, subject to the contract.

Why the price keeps shifting. Stop-loss pricing and underwriting respond to claims experience, expected utilization, contract terms, and the risk being transferred. A group with adverse claims experience may receive less favorable pricing or terms, and underwriting can affect whether a level-funded or self-funded option is viable.

Getting the deductible right. Choosing the right specific deductible is a balancing act. A lower deductible means more protection but higher stop-loss premiums. A higher deductible saves on premiums but requires more cash reserves. Your broker should model several scenarios using your group's actual claims history so you can see the trade-offs in real numbers, not guesses.

Claims reporting can inform a renewal comparison. How much you see depends on the funding model.

Fully insured. The insurance company owns the claims data. You will see summary reports, maybe some aggregate utilization numbers, but you rarely get the detail needed to make informed decisions about plan design or wellness programs.

Self-funded. You typically receive detailed claims reports from your third-party administrator. You can see which categories of care are driving costs: emergency room visits, musculoskeletal issues, diabetes management, behavioral health. That information lets you target changes that actually move the needle, like adding a telehealth benefit if emergency room use for non-emergencies is high, or adjusting pharmacy tiers if specialty drugs are eating your budget.

Level-funded. It varies. Some insurance companies provide robust data. Others share very little, especially for smaller groups. Before you sign, ask exactly what reporting you will receive, how often, and in what format. If an insurance company will not commit to meaningful data sharing, that is a red flag.

At renewal, available aggregate claims reporting and contract experience can inform the comparison. A fully insured employer and a self-funded or level-funded employer may receive different kinds and amounts of reporting. Any claims or utilization material used in a review must be handled confidentially and only through the licensed agent and authorized vendors responsible for the account.

Contract terms can create material financial obligations. These are the provisions that trip up employers most often.

• Run-out period. When you leave a self-funded or level-funded plan, claims incurred during the contract period but not yet submitted still need to be paid. Your contract should specify how long the run-out lasts and who funds it. Some contracts include run-out coverage in the base cost; others charge a separate fee.
• Rate terms. Ask how long the fixed monthly amount and stop-loss terms apply, and whether any terms can change at renewal or mid-year.
• Terminal liability. This is the money needed to cover claims that were incurred but not yet reported when you terminate a self-funded plan. If you switch to a new plan mid-year, you could be paying two sets of claims simultaneously. Make sure you understand who covers those claims and for how long.
• Surplus handling. On level-funded plans, find out exactly how surplus funds are calculated and returned. Some contracts return the full surplus; others keep a percentage. The timeline matters too: you might wait six to twelve months after the plan year ends before seeing a refund.
• Network access and administrator selection. Self-funded plans let you choose your third-party administrator and, often, your provider network. Confirm whether you can change administrators without terminating the entire arrangement, and check whether the network covers the providers your employees actually use in the Columbia and Midlands area.

Do not rely on a summary sheet from the insurance company.

Your group health plan is one of the largest line items on your books, and the funding model you choose shapes everything from monthly cash flow to long-term cost control.

Whether you are running a five-person office in Irmo or a 50-person operation in Lexington, the right structure depends on your claims history, your risk tolerance, and your appetite for data.
