Self funded plan

What Is a Self-Funded Plan?

A self-funded plan, also known as a self-insured plan, is a type of employee benefit plan where an employer directly assumes the financial risk for providing healthcare benefits to its employees, rather than purchasing a fully insured plan from a commercial insurance carrier. This approach falls under the broader category of employee benefits. Instead of paying fixed premiums to an insurer, a self-funded plan pays medical claims as they are incurred, using the company's own funds. While the employer bears the direct financial risk, many self-funded plans engage a third-party administrator (TPA) to handle administrative tasks such as claims processing, provider network access, and customer service.

History and Origin

The landscape of self-funded plans in the United States is largely shaped by the Employee Retirement Income Security Act of 1974 (ERISA). Prior to ERISA, employee benefit plans were subject to a patchwork of varying state laws, which created complexity for employers operating across multiple states. ERISA was enacted primarily to protect the interests of participants and beneficiaries in employee benefit plans, setting federal standards for reporting, disclosure, and fiduciary responsibilities. Crucially, ERISA includes a preemption clause that generally exempts self-funded health plans from state insurance regulations, allowing them to operate under a single, uniform federal framework regardless of the state in which employees reside. This regulatory consistency significantly encouraged the adoption of self-funded models, particularly among large, multi-state employers. As ERISA celebrates its 50th anniversary, the legal framework it established continues to be the foundation for how self-insured health coverage is structured and governed in the U.S.⁵

Key Takeaways

• A self-funded plan means the employer directly pays for employee healthcare claims rather than paying fixed premiums to an insurance company.
• Employers bear the financial risk, but often mitigate large claims through stop-loss insurance.
• Self-funded plans are primarily regulated by federal law (ERISA), not state insurance laws, offering greater flexibility in plan design.
• Many employers utilize a third-party administrator (TPA) for administrative services, while retaining financial responsibility.
• This model can offer potential cost savings and greater control over benefit offerings compared to fully insured alternatives.

Formula and Calculation

While there isn't a single universal "formula" for a self-funded plan in the way one calculates a financial ratio, the core financial principle revolves around managing expected and unexpected healthcare costs. Employers sponsoring self-funded plans typically estimate their potential claims liability based on historical data, demographic information, and actuarial projections.

The total expected cost for a self-funded plan can be conceptualized as:

Where:

• Expected Claims: This is the statistically projected amount of healthcare expenses for the covered population over a given period, often determined through actuarial science.
• Administrative Fees: Payments to a third-party administrator (TPA) for managing the plan.
• Stop-Loss Premiums: The premium paid for stop-loss insurance, which protects the employer from catastrophic individual or aggregate claims.
• Employee Contributions: The portion of the cost shared by employees through payroll deductions.

This estimation forms the basis for budgeting and setting aside adequate funds, often in a dedicated trust, to cover anticipated expenditures.

Interpreting the Self-Funded Plan

Interpreting a self-funded plan primarily involves understanding its financial implications and flexibility for an employer. For employers, the primary interpretation is that they are assuming direct financial risk management for their employees' healthcare, which can lead to significant cost savings if claims are lower than anticipated. However, it also means exposure to higher costs if claims exceed projections. The decision to self-fund is often driven by a desire for greater cost containment and the ability to customize benefit offerings.

From an employee's perspective, the practical interpretation of a self-funded plan is often indistinguishable from a fully insured plan. Employees still use an insurance card, access provider networks, and pay deductibles, co-payments, and out-of-pocket maximums. The key difference for employees is often in the regulatory oversight, as self-funded plans are governed by federal ERISA laws, which preempt state-specific benefit mandates that might apply to fully insured plans.

Hypothetical Example

Consider "Tech Solutions Inc.," a company with 500 employees. For years, Tech Solutions purchased a fully insured health insurance policy, paying a fixed monthly premium per employee. In 2024, the annual premium reached $15,000 per employee, totaling $7.5 million for the year, regardless of actual claims incurred.

Seeking more control and potential savings, Tech Solutions decided to switch to a self-funded plan for 2025. Based on historical claims data and expert projections, their estimated total claims for 2025 are $6 million. They contract with a TPA for administrative services at an annual cost of $500,000 and purchase stop-loss insurance with a $150,000 per-employee specific stop-loss limit and a $6.5 million aggregate stop-loss limit for a premium of $300,000. Employee contributions are set at $1 million annually.

Under this self-funded plan, Tech Solutions sets aside funds to cover the expected $6 million in claims. If actual claims come in lower, say $5.5 million, the company saves $500,000 that year compared to their projection, and even more compared to the fully insured premium. If claims hit $7 million, the stop-loss insurance would kick in to cover the portion exceeding the $6.5 million aggregate limit, mitigating the employer's exposure. The company manages its cash flow to ensure funds are available as claims arise, which differs from the fixed, predictable premium payments of a fully insured model.

Practical Applications

Self-funded plans are widely used by employers of varying sizes, though they are most common among larger organizations due to the greater ability to absorb financial risk and achieve predictability across a larger employee base. A primary application is in large corporations that can leverage their size to benefit from economies of scale and direct control over their benefit programs. These plans allow employers to customize benefit designs to meet the specific needs of their workforce, unlike the "one-size-fits-all" approach often found with fully insured options⁴. This flexibility extends to provider networks and specific covered services, enabling strategic decisions based on employee demographics and health trends.

Furthermore, self-funded arrangements enable employers to retain control over their health plan reserves, potentially maximizing interest income on those funds until they are needed for claims payments. This can lead to improved cash flow for the organization³. From a regulatory compliance standpoint, self-funded plans are governed by federal law (ERISA) rather than a multitude of state-specific insurance regulations and premium taxes, simplifying administration for multi-state employers².

Limitations and Criticisms

Despite their advantages, self-funded plans come with inherent limitations and criticisms. The most significant drawback for an employer is assuming direct financial risk. While stop-loss insurance mitigates catastrophic claims, unexpected high claims can still strain an employer's balance sheet if not adequately managed or if the stop-loss thresholds are not met. Smaller companies, with less predictable claims experience due to a smaller pool of employees, often find this level of risk prohibitive.

Another area of criticism relates to regulatory oversight. While ERISA preemption offers flexibility, it also means that self-funded plans are not subject to certain state insurance mandates and consumer protections that apply to fully insured plans. This can lead to situations where employees covered by a self-funded plan may not receive certain benefits mandated by their state's insurance laws, potentially causing frustration or confusion. For instance, if a state mandates coverage for a specific medical treatment, this mandate may not apply to a self-funded plan unless the employer voluntarily chooses to include it. Employees in self-funded plans typically have federal appeal rights for denied claims under ERISA, but the lack of state oversight can mean fewer external avenues for recourse.

Self-Funded Plan vs. Fully Insured Plan

The fundamental difference between a self-funded plan and a fully insured plan lies in who bears the financial risk for healthcare costs.

In essence, an employer with a self-funded plan acts as its own insurer, directly managing and funding the healthcare expenses of its employees, whereas with a fully insured plan, the employer transfers that financial risk to an insurance company in exchange for a predictable premium.

FAQs

What happens if claims are higher than expected in a self-funded plan?

If claims exceed expectations, the employer is responsible for paying those claims. To mitigate this risk, most self-funded plans purchase stop-loss insurance. This insurance kicks in when claims for an individual or the entire group exceed a predetermined threshold, protecting the employer from catastrophic financial losses.

Are self-funded plans regulated?

Yes, self-funded plans are regulated primarily by the Employee Retirement Income Security Act of 1974 (ERISA), a federal law enforced by the U.S. Department of Labor. ERISA sets standards for things like disclosure, fiduciary duties, and claims and appeals processes. However, due to ERISA's preemption clause, self-funded plans are generally exempt from state-specific insurance regulations.¹

Do employees pay a premium for a self-funded plan?

Employees often still contribute to the cost of their healthcare coverage through regular payroll deductions, similar to a fully insured plan. These contributions may be referred to as premiums, even though the employer is directly funding the plan rather than an insurance carrier. Employees will also typically have a deductible, co-payment, and an out-of-pocket maximum.

What is a Third-Party Administrator (TPA) in a self-funded plan?

A Third-Party Administrator (TPA) is an independent entity hired by a self-funded employer to manage the day-to-day operations of the health plan. This includes tasks such as claims processing, eligibility management, customer service, and provider network access. The TPA handles the administrative burden, allowing the employer to focus on its core business while still retaining the financial risk and control of the plan.
