For employers considering a self-funded health plan, one of the biggest questions is simple: What happens if claims are higher than expected?
That's where stop-loss insurance comes in.
Stop-loss insurance provides financial protection by limiting an employer's exposure to unexpectedly high health care claims. Rather than eliminating the employer's responsibility for claims, stop-loss establishes predetermined thresholds—known as attachment points—after which the stop-loss carrier reimburses the plan for eligible excess expenses.
There are two primary types of stop-loss protection: specific and aggregate.
Specific Stop-Loss: Protecting Against a Large Individual Claimant
Specific stop-loss protects the plan when claims for one individual participant exceed a predetermined amount.
For example, imagine an employer has a specific attachment point (or stop-loss amount) of $50,000. If an individual participant has $150,000 in eligible employer funded claims during the contract period, the employer's financial responsibility is generally limited to the applicable specific threshold, with the stop-loss carrier reimbursing eligible claims above that amount, subject to the terms of the contract.
This protection is particularly important because a single unexpected event—a serious illness, accident, premature birth, or other significant medical condition—can generate substantial claims.
In simple terms, specific stop-loss protects against the financial impact of a high-cost individual claimant.
Aggregate Stop-Loss: Protecting the Plan as a Whole
Aggregate stop-loss provides a different layer of protection. Instead of looking at one individual, it considers the combined eligible employer funded claims of all plan participants during the contract period.
The aggregate attachment point is generally established above the plan's expected claims. Depending on the plan and stop-loss contract, it may commonly be set at approximately 110%--125% of expected claims.
For example, if a plan's expected annual claims are $1 million and its aggregate attachment point is 120%, the aggregate threshold would be approximately $1.2 million. If eligible claims exceed that threshold, the stop-loss carrier may reimburse the plan for eligible expenses above the applicable aggregate attachment point, according to the contract.
Aggregate stop-loss therefore provides protection against the possibility that the entire plan experiences higher-than-expected claims, even when no single claimant necessarily reaches the specific attachment point.
Two Layers of Protection
Specific and aggregate stop-loss work together to help create a more predictable financial environment for self-funded employers.
- Specific stop-loss protects against unusually large claims from an individual participant.
- Aggregate stop-loss protects against unexpectedly high claims across the plan as a whole.
Together, these protections help employers take advantage of the potential flexibility and cost-control opportunities of self-funding while putting limits around their financial exposure.
Of course, stop-loss protection is governed by the specific terms, conditions, exclusions, and definitions contained in the stop-loss contract. Attachment points, reimbursement provisions, and other contract provisions matter.
The bottom line: Self-funding does not mean an employer has to take an unlimited financial risk. Properly structured stop-loss coverage can provide an important safety net—helping employers manage the uncertainty that comes with health care claims while maintaining greater control over their benefit plan.
