Shopping group health for your team
For small and mid-sized employers in Washington State, group health insurance often feels like a broken binary choice. On one side, there are traditional fully insured plans: predictable but increasingly expensive, devoid of data transparency, and subject to rigid community rating. On the other side is true self-funding: highly flexible and transparent, but carrying volatile cash-flow requirements and massive claims risk that most mid-sized businesses cannot tolerate.
Level-funded health insurance is the engineered middle ground.
Marketed specifically as a hybrid alternative for employers who want the cost-control mechanisms and data transparency of self-funding without the day-to-day exposure to volatile claims risk, level-funding has become a dominant strategy for companies with 20 to 250 employees. In a level-funded plan, you pay a fixed monthly amount—hence the name “level”—just as you would with a fully insured premium. But beneath the surface, that payment is split into a claims fund, an administrative fee, and a stop-loss insurance premium. If your team’s medical claims run low, you get money back. If they run catastrophically high, the stop-loss insurance kicks in, ensuring you never pay a dime over your monthly set rate.
This guide provides a comprehensive breakdown of how level-funded health plans operate in Washington, the intricate mechanics of claims risk and stop-loss contracts, the compliance reality of federal ERISA preemption versus the Washington Office of the Insurance Commissioner (OIC), and the exact criteria HR leaders and executives must evaluate to determine if this funding arrangement is right for their workforce.
To evaluate level-funding, you must first strip away the illusion of the “premium.” When you buy a fully insured policy from carriers like UnitedHealthcare, Premera Blue Cross, or Kaiser Permanente, you pay a premium in exchange for the absolute transfer of risk. What the carrier does with that money is a black box.
When you establish a level-funded plan, you are not buying insurance in the traditional sense; you are financing a self-funded architecture through a predictable installment plan. Your business technically bears the claims risk, but that risk is heavily smoothed and capped.
Every month, the employer pays a set, unvarying amount. That payment is divided by a Third-Party Administrator (TPA) into three distinct buckets:
This portion of the payment goes to the TPA (or the administrative arm of a major insurance carrier) to run the plan. It covers claims adjudication, customer service for your employees, access to a provider network (such as renting a national PPO network), pharmacy benefit management (PBM) fees, and compliance reporting. This is a sunk cost; it does not change regardless of how many claims your employees file, and it is never refunded.
Stop-loss is the safety net that makes level-funding viable for mid-sized companies. It is an insurance policy that the employer buys to protect the plan itself against catastrophic losses. The premium for this stop-loss policy is pulled from your monthly payment. Like the administrative fee, this is a fixed, sunk cost that secures your financial ceiling.
The remainder of your monthly payment—typically the largest portion—is deposited into a dedicated claims fund holding account. When your employees go to the doctor, pick up prescriptions, or visit the hospital, the TPA pays those actual medical bills using the money sitting in this reserve fund.
This is where the magic, and the risk, of level-funding resides. The TPA actuaries calculate the “maximum expected liability”—the absolute worst-case scenario for your group’s claims based on underwriting. Your monthly payment funds this maximum amount.
Because you are funding the worst-case scenario evenly over 12 months, your cash flow is protected from spikes. If a dozen employees need expensive surgeries in February, you do not receive a massive bill in March. The TPA uses the reserves, and if the reserves run dry early in the year, the TPA’s “accommodation” feature essentially advances the funds, settling the math against the stop-loss policy behind the scenes. Your payment remains level.
At the end of the plan year (and a designated run-out period), a final accounting is performed. If the money left in the claims reserve fund is greater than the actual claims paid out, the employer has a surplus. Depending on the contract, the employer receives a percentage of that surplus (often 50% to 100%) back as a cash refund or as a credit toward the next year’s administrative fees.
Level-funding is not a universal solution. It is a highly specific financial instrument designed for a particular segment of the market. Understanding whether your business fits into this “sweet spot” is the first step in the decision matrix.
The target demographic for level-funded plans is the small-to-mid market, generally defined as companies with 20 to 250 employees on the health plan.
Why not smaller businesses? While some carriers offer level-funded products down to groups as small as 5 or 10 employees, micro-groups face extreme volatility. A single cancer diagnosis or premature birth in a 10-person company will instantly blow through the claims fund and trigger the stop-loss policy. Because the pool is so small, one bad year makes the group functionally uninsurable in the level-funded market for the next renewal, forcing them back into fully insured community rating at a massive disruption to the staff.
Why do enterprises skip this step? Large employers—those with 500, 1,000, or more employees—possess the law of large numbers. Their claims become statistically predictable. An enterprise of that size does not need to pay a premium for a TPA to smooth their cash flow into “level” monthly payments. They have the capital reserves to handle monthly cash-flow fluctuations, and they choose to pure self-fund. In a pure self-funded arrangement, the employer only pays for claims as they actually occur week-to-week, keeping the cash on their own balance sheet rather than parking it in a TPA’s reserve fund. Large enterprises skip level-funding entirely.
Because level-funded plans are medically underwritten—meaning the rates are determined by the actual, specific health conditions of your employees—they are inherently designed to reward healthy groups.
If your workforce skews older, has a high prevalence of chronic conditions (like diabetes, heart disease, or costly specialty drug prescriptions), or has ongoing catastrophic claims, level-funding will likely quote higher than a traditional fully insured plan. The mathematical reality is that level-funding only generates a financial advantage if your group’s actual risk is lower than the community average.
| Feature | Fully Insured Group Plan | Level-Funded Group Plan | Pure Self-Funded Plan |
|---|---|---|---|
| Claims Risk | Transferred entirely to carrier | Borne by employer, but capped heavily | Borne entirely by employer (up to stop-loss) |
| Monthly Payment | Fixed premium | Fixed maximum monthly payment | Highly variable based on weekly claims |
| Surplus / Refunds | Carrier keeps 100% of profit | Employer receives refund/credit | Employer retains cash immediately |
| Data Transparency | None (Black Box) | Comprehensive claims data reporting | Complete ownership of all data |
| Underwriting | Community Rated (under 50) | Strictly Medical Underwriting | Actuarial / Medical Underwriting |
| State Mandates | Subject to all WA OIC mandates | Exempt via ERISA (Federal rules apply) | Exempt via ERISA (Federal rules apply) |
To truly understand how a level-funded plan protects your business, you must grasp the mechanics of stop-loss insurance. Stop-loss is the only reason a mid-sized company can survive bearing its own claims risk. It comes in two essential forms, both of which are bundled into your level-funded contract.
Specific stop-loss protects the plan from an exceptionally high claim by a single individual. When establishing the plan, the employer and TPA agree on a specific deductible—often $25,000, $50,000, or $100,000, depending on the size of the group.
If an employee requires an organ transplant that bills out at $400,000, the claims reserve fund is only responsible for the costs up to the specific deductible (e.g., $50,000). The specific stop-loss insurance policy steps in and covers the remaining $350,000. This ensures that one catastrophic illness does not drain the entire pool of money meant to pay for the rest of the company’s routine healthcare.
While specific stop-loss protects against one person having a massive claim, aggregate stop-loss protects against everyone having slightly higher-than-average claims.
Actuaries predict your total claims for the year. The aggregate stop-loss “attachment point” is typically set at 120% or 125% of those expected claims. If the whole company gets the flu, requires minor surgeries, and uses expensive brand-name medications at a rate that pushes total spending beyond that 120% threshold, the aggregate stop-loss insurance pays every dollar above it.
In a level-funded plan, your monthly payment is mathematically calculated to fund exactly up to this 120% aggregate attachment point. Because you are funding the worst-case scenario upfront, you cannot be billed for a deficit at the end of the year. The risk is capped.
When evaluating level-funded contracts, HR executives must look out for “lasers.” A laser occurs when the stop-loss carrier reviews your group’s medical history during underwriting and identifies a specific employee with a known, ongoing, high-cost condition (for example, someone receiving active chemotherapy).
Instead of applying the standard $50,000 specific deductible to that employee, the carrier “lasers” them out, assigning them a unique specific deductible of $250,000, or excluding their condition from stop-loss coverage entirely. In a standard level-funded environment, severe lasering usually ruins the financial viability of the plan, signaling that the group is better off staying in the fully insured market where preexisting conditions must be absorbed into the community rate.
One of the most complex, yet critical, components of a level-funded contract is the difference between “incurred” claims and “paid” claims. This distinction dictates how your contract handles the end of the plan year, and it is where many employers get financially trapped if they don’t understand the terms.
A medical claim is incurred on the date the service is rendered—say, December 15th. However, it takes time for the doctor to bill the network, for the network to route it to the TPA, and for the TPA to cut a check. The claim might not be paid until February 10th of the following year.
If your level-funded contract ends on December 31st, who pays the claim in February?
This is solved by contract types, noted as fractions:
When an employer decides to leave a level-funded plan and return to a fully insured plan, they face terminal liability. The new fully insured carrier will not pay for claims incurred before their policy started. The old TPA will only pay them if the employer funded a run-out period.
High-quality level-funded plans include Terminal Liability Reserve (TLR) funding within the monthly payment, meaning the cost of closing out the plan and paying those trailing claims is already handled. Lower-quality proposals might look cheaper upfront because they strip out TLR, leaving the employer holding a massive bag of unfunded liabilities if they ever try to leave. Executives must explicitly ask their benefits consultant if terminal liability is funded in the quote.
The legal architecture of a level-funded plan fundamentally shifts the regulatory playing field.
In Washington, traditional fully insured health plans are regulated by the state’s Office of the Insurance Commissioner (OIC). The OIC enforces strict community rating rules for small groups, levies a state premium tax (around 2%), and dictates a long list of mandated benefits that every policy must cover—ranging from specific behavioral health requirements to alternative medicine mandates.
Because a level-funded plan is technically a self-funded plan under the law, the claims portion of the plan operates under the federal Employee Retirement Income Security Act of 1974 (ERISA).
ERISA includes a “preemption clause” that legally blocks state governments from treating self-funded employee benefit plans as insurance companies. Therefore:
While escaping state mandates provides flexibility, most employers use that flexibility carefully. Stripping out too many benefits can harm recruitment and retention. The true value of ERISA preemption in level-funding is financial efficiency and uniform administration, particularly for Washington employers who also have remote staff across state lines.
Because level-funding relies on medical underwriting rather than community rating, the process of obtaining a quote is significantly more intrusive than buying a fully insured plan. The stop-loss carrier must accurately predict your group’s risk before committing to an attachment point.
There are two primary methods TPAs use to underwrite a group in Washington:
For smaller groups (typically 20 to 50 employees), employees are required to fill out comprehensive health questionnaires detailing their medical history, current diagnoses, and prescription drug usage. This requires immense coordination by HR. If employees lie or omit major surgeries, the stop-loss carrier can legally deny the claim later on grounds of non-disclosure, placing the liability squarely back on the employer.
For slightly larger groups (often 50+), TPAs use algorithmic underwriting known as GRX. Instead of asking employees to fill out paper forms, the employer submits a simple census (names, dates of birth, zip codes). The underwriting software pings national pharmacy clearinghouses and medical databases to identify what prescription medications your employees are currently taking.
Because medications correlate heavily to specific diagnoses (e.g., insulin for diabetes, biologics for rheumatoid arthritis), the actuaries can predict the group’s medical liability with stunning accuracy without a single employee filling out a form.
If the GRX scrub reveals a highly healthy population, the resulting level-funded quote will be aggressively priced, often 10% to 20% lower than the fully insured community rate. If it reveals high-cost specialty drug utilization, the carrier may decline to quote at all.
Level-funding looks incredibly attractive in year one if your group is healthy. The true test of a level-funded strategy is the renewal.
In a fully insured small-group plan under the ACA, your rates are community-based. If one of your employees gets cancer, your premium next year doesn’t skyrocket based on that claim; the risk is socialized across the state.
In a level-funded plan, you own your data and your risk. If you have an excellent year with low claims, you receive a surplus refund, and your renewal increase will likely be in the low single digits.
However, if your group suffers a terrible year—a premature NICU baby, a cancer diagnosis, and a major car accident—the stop-loss insurance will cover the deficit for year one. You will not pay extra. But when year two arrives, the actuaries now know that your group is high-risk. Your “level” monthly payment for the renewal year will spike massively to account for the new baseline of expected claims, or the specific individual may be lasered.
At this point, many employers panic and try to run back to the fully insured market to hide behind community rating. This is where un-funded terminal liability (as discussed earlier) becomes a nightmare.
The Rule of Level-Funding: It is a long-term strategy, not a one-year rate grab. Executives must view level-funding as a multi-year commitment, understanding that bad years and good years will average out to long-term savings, but only if the company has the stomach to ride out a challenging renewal.
Transitioning to a level-funded plan fundamentally changes the employer’s legal standing. Under ERISA, the employer is named as the Plan Sponsor and the Plan Administrator. You are acting as a fiduciary for your employees’ healthcare funds.
Because HR departments are not equipped to adjudicate medical claims or negotiate hospital discounts, they hire a TPA. The TPA is the engine of the level-funded plan. They process the bills, issue the Explanation of Benefits (EOBs), and handle customer support.
Many major carriers in Washington—such as UnitedHealthcare, Aetna, or Cigna—offer turnkey level-funded products (often branded as “All-Savers” or “Aetna Funding Advantage”). In these bundled products, the carrier acts as the TPA, provides the stop-loss, and rents out their own PPO network.
Alternatively, an employer can build an “unbundled” level-funded plan using an independent TPA, buying stop-loss from a separate reinsurance market, and renting a network like the First Choice Health network or the Premera Blue Cross backbone.
From the perspective of the rank-and-file employee, a level-funded plan is indistinguishable from a fully insured plan. They receive an ID card with a recognizable network logo. They go to the doctor, pay a standard copay, and leave. They are never told that the claims are paid from a corporate reserve fund rather than a carrier’s profit pool.
The only difference employees might experience is a change in the drug formulary or a tighter integration of wellness and care-management programs, which TPAs aggressively push to keep claims costs down.
The single greatest advantage of level-funding for an HR director is data. In a fully insured plan, if you ask the carrier why your rates went up 15%, they will refuse to tell you, citing HIPAA.
In a level-funded plan, the employer receives monthly claims reports (de-identified to protect individual HIPAA privacy, but detailed enough to show trends). You will know exactly how much of your spend is going to pharmacy, how many emergency room visits were unnecessary, and which chronic conditions are driving costs.
Armed with this data, HR can make targeted plan design changes. If emergency room usage is disproportionately high, the employer can implement a zero-dollar telemedicine benefit to divert traffic. If specialty drugs are draining the reserve fund, the employer can carve out pharmacy benefits to a specialized PBM. You can actively manage the plan rather than passively receiving rate hikes.
Deciding to move from a fully insured model to a level-funded architecture requires careful alignment of company demographics, financial health, and risk tolerance. Use this situation-to-action map to guide your strategy:
Situation 1: You have fewer than 20 employees and experience regular turnover.
Situation 2: You have 30–150 employees, a generally healthy, younger demographic, and are frustrated by double-digit community rate hikes.
Situation 3: You have 50–200 employees, but you have known, ongoing catastrophic health conditions within the staff (e.g., active chemotherapy, dialysis).
Situation 4: You are an enterprise with 300+ employees and strong cash reserves.

Get a Free ConsultationLevel-funded health insurance is the most powerful tool available to mid-market Washington employers looking to break free from the perpetual cycle of fully insured rate hikes. It demands more engagement from HR, a deeper understanding of stop-loss contracts, and the discipline to view health benefits as a multi-year financial strategy. But for the right company, the reward of data transparency, regulatory flexibility, and the return of unspent claims dollars makes the transition exceptionally profitable.
