Stop-Loss Insurance

Stop-loss insurance is coverage that a self-funded employer buys to limit its financial exposure when health claims run unusually high. The employer pays claims up to an agreed threshold, and the stop-loss carrier reimburses the employer for amounts above it.

It is the safety net behind most self-funded plans, including administrative services only arrangements. It protects the employer's finances, not the employee's coverage, which stays under the plan.

What Are the Two Main Types of Stop-Loss Coverage?

Stop-loss policies usually contain two protections. Specific stop-loss covers the cost of any single covered person that passes the individual deductible, which guards against one very large claim, such as a premature birth or a transplant.

Aggregate stop-loss covers the plan's total claims for the year. It responds when many ordinary claims add up and pass a set share of expected claims, even if no single case was unusually costly.

Employers can buy one or both. Most combine them, because the two risks, one catastrophic case and a broad rise in utilization, are different.

What Is an Attachment Point?

The attachment point, sometimes called the retention or deductible, is the dollar amount the employer must pay before the stop-loss carrier starts reimbursing. A lower attachment point means more protection and a higher stop-loss premium.

Choosing it is a balance. Employers with strong cash reserves can accept a higher attachment point to keep premiums down, while smaller employers often choose a lower one to avoid large swings.

The attachment point also interacts with the contract period. Policies can cover claims incurred and paid in the same period, or include run-in or run-out terms, so the wording matters.

How Is Stop-Loss Regulated?

The Department of Labor has said stop-loss insurance generally is not treated as health insurance under state law, because it protects the employer rather than the plan member. States regulate it as insurance, and the Department's view is that state laws setting minimum attachment points are not preempted by ERISA.

In practice, rules differ by state. Some states set minimum attachment points for small employers, so a quote that works in one state may not be allowed in another.

Employers should confirm that their policy matches the plan document. Gaps between the two, such as different definitions of covered services, are a common source of disputes.

What Should HR Watch For in a Stop-Loss Contract?

HR rarely signs the contract alone, but it often feels the effects. These items deserve a careful read:

• Individual exclusions: a carrier may set a higher deductible for a person with a known high-cost condition.
• Reimbursement timing: how quickly the carrier pays and what documentation it needs.
• Contract period: whether claims must be incurred and paid within the same period.
• Plan alignment: whether the stop-loss policy follows the plan document word for word.

How Does Stop-Loss Relate to Level-Funded and Self-Funded Plans?

Stop-loss is the common thread. A fully self-funded employer chooses its own attachment points, while a level-funded plan usually bundles pre-set stop-loss terms into one monthly payment.

That packaging is why level-funded plans are easier for small employers, but it also means they have less room to customize coverage. An employer with a large cash reserve may prefer separate, higher attachment points and lower premiums.

Whichever structure is used, the employer should treat stop-loss as part of the plan design and not as an afterthought. The wrong attachment point can turn a good plan into a financial risk.

How Can HR Cloud Help With Stop-Loss Coverage?

HR Cloud does not offer stop-loss or claims tools in its published materials. What People HRIS can do is keep plan documents, notices and approvals organized, since it offers secure document storage with version tracking and automated approvals and task assignments.

Frequently Asked Questions

Q: Who buys stop-loss insurance?

A: The employer that sponsors a self-funded health plan. Employees do not buy it and are not covered by the stop-loss policy itself.

Q: Is stop-loss insurance the same as health insurance?

A: No. Health coverage pays for an individual's medical care. Stop-loss reimburses the employer's plan when claims pass an agreed limit.

Q: What is the difference between specific and aggregate stop-loss?

A: Specific coverage applies per person when one claimant's costs exceed the individual deductible. Aggregate coverage applies when the whole plan's claims pass a total threshold.

Q: Does stop-loss reduce employee benefits?

A: No. Employees see the same plan benefits. The policy only affects who ultimately pays the largest claims.

Q: Can a stop-loss carrier deny a claim?

A: Yes, if the claim falls outside the policy terms, such as an excluded condition or a service the plan document did not cover. Careful plan alignment reduces this risk.

Q: Do small employers need stop-loss?

A: Almost always. A small group has little capacity to absorb one very large claim, so carriers and advisers treat stop-loss as essential for small self-funded plans.
