In a self-funded health plan, the employer pays employee healthcare claims directly instead of paying fixed premiums to an insurer, often using a TPA to administer claims and stop-loss insurance to cap financial risk.
If you’re an HR leader trying to get a handle on rising healthcare costs, you’ve probably heard self-funding come up in conversations with your benefits broker, finance team, or leadership. And for good reason: Self-funded plans have quickly become a major player in employer-sponsored healthcare. In fact, 67% of covered workers are enrolled in self-funded health plans—and that number rises to 80% at firms with 200 or more employees.
So, what’s behind the interest? Self-funding can give employers greater control over their benefits strategy, more visibility into healthcare spending, and opportunities to manage costs. But it also comes with financial risk, administrative considerations, and a responsibility to help employees make informed healthcare decisions.
Let’s break down how self-funded health plans work, how they compare with fully insured plans, and what HR teams should know before exploring their options.
What is a self-funded health plan?
A self-funded health plan is one in which your organization pays for employees’ healthcare claims directly instead of paying a fixed premium to an insurance carrier.
Here’s a simplified example.
Imagine your company has 1,000 employees enrolled in its health plan. With a traditional fully insured plan, you might pay a monthly premium of $700/employee ($700,000 total). With a self-funded plan, you wouldn’t pay that premium.
Instead, you’d pay for the actual cost of the procedure when Employee A needs a hip replacement. And when Employee B needs chemotherapy. And when Employee C needs an MRI. You might contract with a third-party administrator (TPA) to process claims, manage provider networks, and handle other administrative tasks.
Why do employers like this model?
There’s potential for a huge financial upside: if employees’ medical claims come in lower than expected, your company may spend less on healthcare than it would have under a comparable fully insured arrangement.
But if claims are higher than expected, your company is on the hook for those additional costs. That’s the fundamental trade-off: more control over healthcare spending, but also more direct responsibility for the cost of care.
How does self-funding work in practice?
Although plan designs vary, a self-funded arrangement generally follows a few steps:
- Your company establishes the plan. You determine what health treatments and procedures are covered, who’s eligible, what your cost-sharing structure will be, and other plan provisions.
- Employees enroll and receive care. Employees use their health coverage for eligible services, just as they would with a fully insured plan.
- Claims are processed. A TPA or insurance company providing administrative services reviews and processes claims according to the plan’s terms.
- You pay for covered claims. Your organization covers the cost of eligible claims, often through a dedicated account.
- You review spending. Claims and utilization data can help your company understand yearly healthcare costs, identify trends, and evaluate potential changes to your benefits strategy.
Self-funded vs. fully insured: What’s the difference?
Both self-funded and fully insured plans can provide employees with comprehensive health coverage. The biggest difference is who takes financial responsibility for covered medical claims.
A fully insured plan is what most folks think of as traditional employer-sponsored healthcare. With these plans, you, as the employer, pay your insurance company a predetermined premium, while a carrier assumes responsibility for any claims your employees file.
With a self-funded plan, you (as the employer) pay employees’ claims as they occur, often using a third-party administrator (TPA) to handle plan administration and claims processing.
Here’s how the two approaches compare:
Self-funded health plan vs. fully insured health plan
Consideration
Self-funded health plan
Fully insured health plan
Who pays medical claims?
Self-funded health plan: The employer pays covered claims from its own funds.
Fully insured health plan: The insurance company pays covered claims under the policy.
How are costs structured?
Self-funded health plan: Claims fluctuate based on employees’ healthcare use, alongside administrative fees and other plan expenses.
Fully insured health plan: The employer pays a predetermined premium for coverage during the policy period.
Who assumes the claims risk?
Self-funded health plan: The employer, subject to any stop-loss protection.
Fully insured health plan: The insurer.
How much flexibility does the employer have?
Self-funded health plan: Generally more flexibility to customize plan design and administration, within applicable legal requirements and contractual arrangements.
Fully insured health plan: Plan options and changes are generally shaped by the insurer’s available products and policy terms.
What claims data is available?
Self-funded health plan: Employers may receive more detailed claims reporting, subject to privacy rules, minimum reporting thresholds, and contractual access.
Fully insured health plan: The insurer typically manages the claims data and provides reporting under the policy arrangement.
Who handles administration?
Self-funded health plan: Often a TPA or an insurer under an ASO arrangement.
Fully insured health plan: The insurer generally handles claims administration.
What are the advantages of self-funded health plans?
- Potential cost savings: If claims are lower than expected, employers may spend less than they would with a fully insured plan. However, savings aren’t guaranteed, and administrative fees, stop-loss premiums, and other expenses still need to be considered.
- Greater plan flexibility: Employers generally have more control over plan design and can tailor their benefits coverage to their workforce’s needs. That flexibility may make it easier to explore specific coverage options or adapt the plan as employee needs change.
- More visibility into healthcare spending: Access to claims and utilization reporting can help employers identify top cost drivers, evaluate plan performance, and make more informed decisions about future benefits investments.
- Potential for more targeted cost-containment strategies: When employers better understand where healthcare dollars are going, they can investigate opportunities to improve access, encourage appropriate care, and help employees make informed choices.
What are the disadvantages of self-funded health plans?
- Unpredictable claims costs: A handful of high-cost claims or a year of unexpectedly heavy healthcare utilization can increase spending significantly. Stop-loss coverage can reduce that risk, but it doesn’t eliminate it entirely.
- Greater financial responsibility: Employers need enough cash flow to pay claims as they arise. They also need to plan for fluctuations rather than assuming healthcare costs will remain consistent month to month.
- More administrative complexity: Even with a TPA, HR and finance teams need to oversee vendors, monitor plan performance, understand their responsibilities, and coordinate employee communications.
- More responsibility for employee education: A flexible plan doesn’t automatically translate into better healthcare decisions. Employees still need to understand their coverage, provider networks, deductibles, and out-of-pocket costs to use their benefits effectively.
Self-funding can be a good fit for employers with the resources, expertise, and risk tolerance to manage these responsibilities. But it isn’t automatically the best choice for every organization. A benefits broker or consultant can help evaluate the financial implications, workforce needs, and administrative requirements before you make the switch.
What is stop-loss insurance?
Stop-loss insurance is a type of coverage that helps protect employers operating self-funded health plans against unexpectedly high medical claims.
Think of it as a financial backstop. Your organization is still responsible for paying covered claims, but stop-loss coverage can reimburse eligible costs if you’re hit with surprisingly high medical bills.
There are two main types of stop-loss insurance:
Specific stop-loss insurance
Specific stop-loss insurance protects against unusually high claims for an individual employee or plan participant.
For example, imagine your plan has a specific stop-loss cap of $100,000 per person. If one employee incurs $250,000 in eligible claims during the applicable coverage period, your stop-loss policy might reimburse your company for those overages.
The exact amount and timing of reimbursement depend on the policy. The stop-loss cap isn’t necessarily the same as an employee’s out-of-pocket maximum, and it doesn’t change the benefits the employee receives under your health plan.
Aggregate stop-loss insurance
Aggregate stop-loss insurance protects against overspending when it comes to your employee population as a whole.
Suppose your company sets an aggregate stop-loss threshold of $2 million, which is what you usually spend on claims every year. But this year, your workforce’s total claims costs came out to $5 million. In that case, your stop-loss policy might reimburse you for those higher-than-usual costs.
The actual threshold is determined by your specific policy, and might account for factors like who’s enrolled, which expenses are covered, and what’s excluded.
Why does stop-loss insurance matter?
Without stop-loss coverage, your company can potentially be exposed to unmanageable fluctuations in claims costs. Stop-loss insurance can help you plan for worst-case scenarios, and ensure you’re covered if your healthcare spending is unexpectedly high.
When evaluating policies, your HR team should look beyond the premium. The level of protection you receive depends on spending thresholds, exclusions, contract terms, and reimbursement timing.
The goal isn’t simply to buy the cheapest stop-loss policy. It’s to find a level of protection that fits your organization’s financial capacity and risk tolerance.
How do TPAs support self-funded plans?
A self-funded health plan gives an employer more direct responsibility for paying claims, but that doesn’t mean the HR team has to manage every moving part itself.
That’s where a third-party administrator (TPA) comes in.
A TPA is an organization that provides administrative services for a health plan. In a self-funded arrangement, the TPA manages the plan’s operations, while the employer covers medical claims.
Depending on the agreement, a TPA may offer services like:
- Claims processing: Reviewing medical claims and determining whether they’re payable under the plan.
- Member support: Answering employees’ questions about coverage, claims, and benefits.
- Provider network access: Helping enrollees access covered provider networks, depending on the arrangement.
- Plan administration: Supporting enrollment, eligibility, documentation, and other administrative processes.
- Reporting and analytics: Providing claims and utilization reports that help employers understand spending patterns.
- Compliance support: Helping with certain administrative requirements, although the employer is ultimately responsible for meeting its own legal obligations.
How should you choose a TPA?
The right TPA should do more than process claims accurately. It should help your organization administer the plan efficiently and give you the information you need to make informed decisions.
Here are a few questions to ask when evaluating potential partners:
- What reporting will we receive? Ask how frequently the TPA provides claims and utilization data, what level of detail is available, and how it protects employee privacy.
- How will you support our workforce? Ask about how employees will access plan support, if multilingual resources are available, and how employees can get help when they have questions.
- Do you work with other vendors? Find out how your TPA will partner with your stop-loss carrier, pharmacy benefit manager, wellness partners, and benefits decision support tools.
- What are the fees and service commitments? Make sure you understand the administrative fee structure, performance guarantees, implementation process, and procedures for resolving problems.
- Will we have the flexibility we need? Ask how the TPA accommodates your plan design, supports changes, and helps you evaluate performance over time.
How does ALEX Home support employees who are enrolled in self-funded plans?
Self-funding can give employers more insight into healthcare spending. But having data about your plan is only half the equation. The other half is helping employees make informed decisions about their care.
After all, a health plan can be thoughtfully designed, competitively priced, and supported by excellent vendors. But if employees don’t understand their coverage or know how to use it, they’ll struggle to get the most value from their benefits.
That’s where an employee benefits decision support tool like ALEX can make a difference. Here’s how.
ALEX Home helps employees understand their options
Healthcare decisions can be confusing, especially when employees compare plans, try to understand deductibles, or figure out what a particular service might cost. Because self-funded plans are less familiar than traditional plans, employees may need extra support to understand what’s involved.
ALEX helps employees understand their options through personalized, conversational guidance. Rather than expecting employees to decipher a stack of plan documents on their own, ALEX helps them make smarter decisions based on their individual circumstances and your organization’s specific benefits package.
During open enrollment, that can mean helping employees understand the differences between plans and decide which coverage best fits their needs, preferences, and financial situation.
But the support doesn’t stop when enrollment ends. ALEX Home is there throughout the year, when employees have in-the-moment questions as they seek care, start a new treatment, or experience life changes.
ALEX Home connects benefits decisions to cost containment
Here’s where decision support becomes especially relevant for employers with self-funded plans.
When employees make smarter benefits decisions, it means cost savings for them—and for you. And when you cover claims costs directly, it’s especially important to make sure employees use their health plans wisely—year-round.
For example, employees who understand their plan’s provider network may be better equipped to find the right doctor at a lower cost. Those who understand their coverage and cost-sharing responsibilities can make more informed choices when comparing available care options. And folks who stay up to date on preventive care mean lower claims costs for you down the road.
ALEX Home makes those goals possible at scale, by showing employees their personal financial responsibilities at enrollment, chatting with employees in key moments (like when they’re looking for a new doctor), and sending timely reminders throughout the year.
The best part? Those nudges lead to greater healthcare cost containment for your organization.
ALEX Home makes employee experience part of the strategy
It’s easy to focus on the financial mechanics of self-funding: claims costs, stop-loss coverage, administrative fees, and utilization reports.
But behind every claim is a person trying to get the care they need.
Employees who can’t understand their benefits may delay care, miss useful resources, or struggle with their financial responsibilities. Clear, accessible guidance can help them navigate their options with greater confidence. And when they feel supported, engaged, and healthy? They trust you more as their employer.
For HR teams, personalized benefits support can also help reduce the burden of repeatedly answering the same questions. Instead of being the sole source of information for every benefits decision, HR can give employees another resource to turn to when they need help.
Bringing it all together: Is self-funding right for your organization?
Self-funded health plans can offer employers greater flexibility, more visibility into healthcare spending, and opportunities to manage costs better. They also bring greater financial responsibility, administrative complexity, and a need for thoughtful risk management.
Before deciding, your HR team should consider your organization’s financial resources, claims history, workforce needs, risk appetite, and access to experienced benefits partners. Be sure to account for administrative fees, stop-loss premiums, claims unpredictability, compliance responsibilities, and the employee experience—not just the projected savings.
And remember: funding your plan is only one part of managing healthcare costs. The way you design your benefits, support employees, and help people navigate healthcare decisions matters, too.
