Quick Answer
What is a self-funded health plan? A self-funded (or self-insured) health plan is one where your employer pays for your medical claims directly from its own funds, rather than purchasing insurance from a carrier. A third-party administrator (TPA)—often a company like Cigna, Anthem, or UnitedHealthcare—processes claims and manages the network, but the money comes from your employer. According to the KFF 2025 Employer Health Benefits Survey, 67% of covered workers are enrolled in self-funded plans. Your insurance card may show a major carrier’s logo, but in most cases, the carrier is the administrator, not the one paying your claims.
Why 67% of American Workers Are in Self-Funded Health Plans — And Most Don’t Know It
Take out your health insurance card. Look at it.
It probably says Cigna, or Anthem, or Aetna, or UnitedHealthcare. It has a member ID, a group number, copay amounts, and a customer service phone number. Everything about it looks and feels like insurance.
There is a roughly two-in-three chance it isn’t.
According to the KFF 2025 Employer Health Benefits Survey, 67% of covered workers in the United States are enrolled in self-funded health plans. Among employees at large firms (200+ workers), the figure is 80%. That card in your wallet? The logo on it is almost certainly the third-party administrator—the company that processes your claims. Your employer is the one that pays them.
Most people have no idea. And the distinction matters more than you’d think.
The Statistic That Surprises Everyone
Self-funded health plans are not an alternative model. They are the dominant model for American employer-sponsored health coverage.
KFF’s annual Employer Health Benefits Survey—the most comprehensive data source on employer-sponsored coverage—has tracked the steady growth of self-funding for over two decades. In 2025, 67% of covered workers were enrolled in self-funded plans, up from 63% in 2024 and 61% in 2022. Among large employers (200+ workers), 80% of covered workers are in self-funded plans. Even among small firms (10–199 workers), the figure has reached 27%—up from 20% in 2024—driven partly by the growth of level-funded arrangements.
Add it up and the picture is clear: if you receive health coverage through an employer in the United States, the majority probability is that your plan is self-funded. The insurer whose name is on your card is, in most cases, a service provider to your employer—not the entity bearing the financial risk of your healthcare.
Why You Can’t Tell by Looking at Your Card
The confusion is by design—not malicious design, but structural design.
When an employer self-funds its health plan, it hires a third-party administrator (TPA) to handle the operational side: processing claims, managing provider networks, issuing insurance cards, running the customer service line, and providing the technology platform employees use to check benefits and find doctors.
The TPA is often a major insurance carrier. Cigna, Anthem Blue Cross Blue Shield, Aetna, and UnitedHealthcare all serve as TPAs for self-funded plans—while also selling fully insured products under the same brand. From the employee’s perspective, the experience is identical. The card looks the same. The app works the same. The network is the same.
The difference is invisible but consequential: in a fully insured plan, the insurance company assumes the financial risk and pays claims from its own reserves. In a self-funded plan, your employer assumes the risk and pays claims from its own funds (or a dedicated trust), and the TPA acts as an administrator, not an insurer.
The analogy: imagine you own a restaurant but hire a management company to run the day-to-day operations. Customers see the management company’s name on the menu, the staff wears the management company’s uniforms, and the phone number goes to the management company’s call center. But you own the restaurant. You pay the bills. That’s the TPA relationship in a self-funded plan.
What “Self-Funded” Actually Means in Practice
The mechanics of a self-funded plan are straightforward, though the terminology can be confusing.
| Component | What Happens | Who’s Responsible |
| Claims funding | When you visit a doctor, the plan pays the provider. In a self-funded plan, that money comes from the employer’s funds. | The employer (plan sponsor) |
| Claims processing | A TPA reviews claims, applies plan rules, determines coverage, and pays providers according to the plan document. | The TPA (e.g., Cigna, Anthem, Aetna) |
| Network management | The TPA provides access to its provider network, including negotiated rates with hospitals and physicians. | The TPA |
| Stop-loss protection | The employer purchases stop-loss insurance to cap exposure to catastrophic claims (individual or aggregate). | A stop-loss carrier (often a separate insurer) |
| Plan governance | Self-funded plans are governed by federal ERISA law, not state insurance regulations. The employer is the plan sponsor and fiduciary. | Federal law (ERISA) + the employer |
| Plan design | The employer decides what the plan covers: benefits, networks, cost-sharing, exclusions. | The employer (with TPA guidance) |
The practical experience for employees is largely the same whether a plan is self-funded or fully insured. You use the same network. You see the same doctors. Your copays and deductibles work the same way. The difference is structural—who bears the financial risk and which regulatory framework governs the plan.
Why Employers Choose Self-Funding
The growth of self-funded plans from a niche strategy to the majority model didn’t happen by accident. Several structural advantages drive the choice.
Cost Transparency and Control
In a fully insured plan, the employer pays a fixed premium and has limited visibility into how that premium is determined or spent. In a self-funded plan, the employer sees the claims—what’s being spent, on what, in which categories. This transparency enables more targeted cost management: identifying high-cost areas, adjusting plan design, and investing in prevention where the data indicates the greatest need.
Avoiding State Premium Taxes and Mandates
Fully insured plans are subject to state insurance regulations, including state premium taxes (typically 2–3% of premiums) and state-mandated benefit requirements that vary by jurisdiction. Self-funded plans, because they are governed by federal ERISA law, are exempt from most state insurance regulations through ERISA preemption. For multi-state employers, this creates a single regulatory framework rather than a patchwork of state-by-state requirements.
Customized Benefits Design
Self-funding gives employers flexibility to design benefits that match their specific workforce’s needs. A technology company with a young workforce may emphasize fertility and mental health benefits. A manufacturing company with an older workforce may prioritize chronic disease management and musculoskeletal care. This customization is more limited under fully insured arrangements where the insurer sets the plan parameters.
Access to Claims Data
Self-funded employers own their claims data—aggregate information about how the plan is being used, where costs are concentrated, and which programs are producing results. This data enables evidence-based benefits strategy. Fully insured employers typically receive limited data from their carrier.
Multi-State Consistency
An employer with workers in 15 states can offer one self-funded plan design across all locations. A fully insured plan would need to comply with each state’s insurance regulations and benefit mandates, potentially creating different coverage in different states. ERISA preemption makes self-funded plans operationally simpler for distributed workforces. (For a detailed comparison of how ERISA governs employer plans, see our guide to ERISA-based employer health models.)
What Self-Funded Status Means for Your Rights
Here is where the invisible distinction between self-funded and fully insured becomes very visible—if you ever have a problem.
Same ACA Protections (for Large Employers)
Self-funded plans offered by large employers (50+ full-time equivalent employees) are subject to ACA market reforms. This means they must cover preventive services without cost-sharing, eliminate annual and lifetime limits on essential health benefits, cover dependents to age 26, and prohibit pre-existing condition exclusions. On these fundamentals, self-funded and fully insured plans offer the same protections.
Different Appeals Process
This is the biggest practical difference. If your claim is denied in a fully insured plan, you can appeal through the insurer and, if necessary, through your state insurance department, which has regulatory authority over the carrier.
If your claim is denied in a self-funded plan, your appeals follow the federal ERISA claims procedure—not your state’s process. Your state insurance department generally has no jurisdiction over self-funded ERISA plans due to federal preemption. Appeals go to the plan administrator (your employer or the designated fiduciary), then to external review under federal standards, and ultimately to federal court under ERISA §502(a). (For step-by-step guidance on this process, see our guide to the ERISA claims appeal process.)
Where to Go for Help
If you have a complaint about a self-funded plan, the appropriate federal agency is the Department of Labor’s Employee Benefits Security Administration (EBSA), not your state insurance department. EBSA can investigate whether the plan followed proper procedures and contact the plan on your behalf. The contact number is 1-866-444-3272.
Key point: knowing whether your plan is self-funded or fully insured before you have a problem tells you where to direct complaints and appeals. Many people discover the distinction for the first time when their state insurance department tells them “we can’t help you with this plan”—a frustrating experience that advance knowledge prevents.
How to Find Out If Your Plan Is Self-Funded
This information is available to you. Here’s where to look.
Check Your Summary Plan Description (SPD)
Every ERISA plan is required to provide a Summary Plan Description. This document identifies the plan sponsor (your employer), the plan administrator, and the type of plan. Self-funded plans will typically state that the employer sponsors and funds the plan, and will identify a separate TPA as the claims administrator. Look for language like “the employer pays claims from its general assets” or “this plan is self-funded.”
Ask Your HR Department or Benefits Administrator
A direct question—“Is our health plan self-funded or fully insured?”—will get a direct answer. This is not sensitive information. Your HR team or benefits administrator can confirm the plan’s funding structure.
Look for Clues on Plan Documents
- If the plan identifies a TPA as “claims administrator” and your employer as “plan sponsor” or “plan administrator,” it’s likely self-funded.
- If stop-loss coverage is mentioned, the plan is self-funded (fully insured plans don’t need stop-loss).
- If the plan references ERISA fiduciary responsibilities and the employer’s role in benefit determinations, it’s self-funded.
- If your benefits card lists a “group number” associated with a major carrier but your employer is not the carrier, the carrier is likely acting as TPA for a self-funded plan.
The Bottom Line: Self-Funded Plans Are the Norm, Not the Exception
Self-funded health plans are not unusual, risky, or second-tier. They are the majority model for American employer-sponsored health coverage—covering two-thirds of all workers with employer plans and 80% of workers at large firms.
The model works because it gives employers cost transparency, design flexibility, and data access—while employees receive the same networks, the same ACA protections, and the same day-to-day experience as those in fully insured plans.
What differs is the governance structure (federal ERISA rather than state insurance law), the appeals process (federal rather than state), and the entity bearing financial risk (your employer, backstopped by stop-loss insurance, rather than a carrier).
Understanding this distinction doesn’t change your coverage. It changes your ability to navigate the system effectively when you need to—knowing where to direct appeals, who the plan administrator actually is, and why your state insurance department may not be able to help.
The card in your wallet tells you who processes your claims. Your plan documents tell you who pays them. Now you know to check.
Frequently Asked Questions
What is a self-funded health plan?
A self-funded (or self-insured) health plan is one where the employer pays for employees’ medical claims directly from its own funds, rather than purchasing insurance from a carrier. A third-party administrator handles claims processing, network management, and customer service. According to KFF’s 2025 survey, 67% of covered workers are in self-funded plans.
Is a self-funded plan the same as having no insurance?
No. Self-funded plans provide real health coverage—with networks, benefits, and protections. The difference is who pays the claims: in a fully insured plan, an insurance carrier pays; in a self-funded plan, your employer pays. Employees receive the same practical coverage either way.
Why does my insurance card say Cigna if my plan is self-funded?
Because Cigna (or Anthem, Aetna, UnitedHealthcare, etc.) is acting as the third-party administrator—processing claims and managing the network on behalf of your employer. The logo represents the administrator, not the entity paying your claims.
Can my state insurance department help with a self-funded plan complaint?
Generally, no. Self-funded ERISA plans are exempt from state insurance regulation due to federal preemption. Complaints and appeals go through the plan’s internal ERISA procedures and, for federal oversight, to the Department of Labor’s Employee Benefits Security Administration (EBSA) at 1-866-444-3272.
Are self-funded plans less protective than fully insured plans?
Not in terms of coverage. Self-funded plans offered by large employers are subject to ACA market reforms including pre-existing condition protections, preventive care coverage, and dependent coverage to age 26. The appeals process differs (federal ERISA rather than state insurance department), but the coverage protections are comparable.
How do I find out if my plan is self-funded?
Check your Summary Plan Description (SPD) for language identifying the employer as plan sponsor and a separate TPA as claims administrator. You can also ask your HR department directly. The presence of stop-loss coverage in plan documents is another indicator of self-funded status.
