What Is Stop Loss Insurance and Why Should Your Business Consider It?

Healthcare costs can be unpredictable. If your company offers a self-funded or level-funded health plan, you might save money compared to a fully insured plan, but there’s also a risk—what happens if an employee has a major medical emergency?

This is where stop loss insurance comes in. It helps protect businesses from unexpectedly high medical claims, ensuring that a few large claims don’t drain your company’s budget.

If you’re wondering what stop loss insurance is, how it works, and whether your business needs it, here’s everything you need to know.

What Is Stop Loss Insurance?

Stop loss insurance is a type of coverage designed to protect employers from large healthcare claims. It’s specifically used by companies that self-fund their health insurance plans.

With a traditional fully insured plan, an insurance company takes on all the risk. But with self-funded or level-funded plans, the employer pays employee medical claims directly. Stop loss insurance helps limit that risk by covering claims that go beyond a set threshold.

Without stop loss insurance, a single high-cost medical event—such as cancer treatment, a major surgery, or a premature birth—could significantly impact a company’s finances.

How Does Stop Loss Insurance Work?

A company with stop loss insurance sets a financial limit on how much it will pay for employee healthcare costs. If claims exceed that limit, the stop loss insurance policy covers the extra amount.

There are two types of stop loss insurance:

1. Specific Stop Loss Insurance

  • Protects against large claims for a single employee.
  • Example: If your stop loss threshold is $50,000 per employee and one worker racks up $200,000 in medical bills, your business pays $50,000, and the insurer covers the remaining $150,000.

2. Aggregate Stop Loss Insurance

  • Protects against high total claims across all employees.
  • Example: If your company expects to spend $500,000 on healthcare but claims reach $700,000, the insurer covers the extra $200,000 after you reach your limit.

Many businesses use both types of stop loss insurance to protect against individual high-cost cases and overall rising healthcare costs.

Who Needs Stop Loss Insurance?

If your business has a self-funded or level-funded health plan, stop loss insurance is essential. It’s especially useful for:

✔ Small and mid-sized businesses – These companies have fewer employees, meaning one large claim could have a bigger impact on their budget.
✔ Growing companies – As your workforce expands, so do healthcare risks. Stop loss insurance ensures that an unexpected surge in claims doesn’t derail your financial plans.
✔ Companies switching from fully insured to self-funded plans – If you’re transitioning to a self-funded model, stop loss insurance provides a safety net as you take on more financial responsibility.

If your business has a fully insured plan, you don’t need stop loss insurance because the insurance company already assumes all the risk.

Benefits of Stop Loss Insurance

1. Financial Protection Against Large Claims

One of the biggest risks with self-funded healthcare is unpredictability. Stop loss insurance limits your liability, preventing a few costly claims from harming your business.

2. Predictable Budgeting

Without stop loss insurance, self-funded health plans can have unpredictable costs. By setting clear limits, businesses can better forecast expenses and manage their budget.

3. More Control Over Health Benefits

Self-funded plans give employers flexibility to design their own benefits. Stop loss insurance allows companies to take advantage of cost savings while reducing the financial risks associated with large claims.

4. Lower Overall Healthcare Costs

Companies that self-fund their health plans often pay less than those with fully insured plans. Stop loss insurance adds a layer of protection without requiring them to give up cost savings.

5. Protection From Catastrophic Events

Serious medical conditions—like cancer, transplants, or long-term hospital stays—can cost hundreds of thousands of dollars. Stop loss insurance ensures that these extreme cases don’t bankrupt your health plan.

Choosing the Right Stop Loss Insurance

Not all stop loss insurance policies are the same. When choosing a policy, consider:

✔ Thresholds & Deductibles – How much risk is your company willing to take before stop loss insurance kicks in?
✔ Coverage Type – Do you need both specific and aggregate stop loss insurance?
✔ Reimbursement Speed – Some insurers take months to reimburse claims. Look for a provider with fast processing.
✔ Policy Limits – Ensure that your policy provides enough coverage for worst-case scenarios.
✔ Network Access – Some stop loss insurance providers partner with networks to offer better rates on medical care.

It’s a good idea to work with an insurance broker or benefits consultant to find the right stop loss insurance for your business.

Common Questions About Stop Loss Insurance

How much does stop loss insurance cost?

The cost of stop loss insurance depends on your company’s size, claims history, and the deductible levels you choose. Higher deductibles mean lower premiums, while lower deductibles result in higher premiums.

Can businesses switch stop loss insurance providers?

Yes. Just like any other insurance policy, businesses can change providers if they find a better deal or more suitable coverage.

Does stop loss insurance cover all medical claims?

No. Stop loss insurance only covers claims that exceed the set deductible. Routine claims and expenses below that threshold are paid by the employer.

Is stop loss insurance required?

No, but it is highly recommended for self-funded and level-funded health plans. Without it, businesses take on significant financial risk.

Should Your Business Consider Stop Loss Insurance?

If your company offers a self-funded or level-funded health plan, stop loss insurance is one of the best ways to manage risk. It allows businesses to:

✔ Save money compared to fully insured plans
✔ Protect against catastrophic claims
✔ Maintain control over health benefits
✔ Budget healthcare costs more predictably

However, if your company has a fully insured health plan, you don’t need stop loss insurance since the insurer already covers all claims.

Final Thoughts

Self-funding healthcare can be a great way for businesses to save money, but it comes with risks. Stop loss insurance provides a safety net, ensuring that no single claim—or series of claims—destroys your company’s financial health.

If your business is considering a self-funded or level-funded plan, adding stop loss insurance can give you the confidence to move forward without worrying about high-cost claims.
