Aggregate Stop-Loss Insurance

What Does Aggregate Stop-Loss Insurance Mean?

Aggregate stop-loss insurance is a form of protection employers use to mitigate the risk of an unusually high volume of claims under a specific coverage within their group employee benefit policy.

Unlike traditional benefits in group employee plans, stop-loss insurance protects only the employer and does not provide direct coverage to employees. On a company’s books it sits with other forms of business insurance rather than with the health plan itself, because the policy reimburses the employer rather than paying medical providers.

Insuranceopedia Explains Aggregate Stop-Loss Insurance

Aggregate stop-loss insurance is designed specifically for self-funded insurance plans, where the employer assumes the financial responsibility for providing healthcare benefits to employees. This insurance functions similarly to a high-deductible policy, with the employer covering all claim expenses up to the deductible amount.

Stop-loss insurance enables employers with self-funded plans to limit their financial liability for excessive claims. Instead of paying an annual premium, employers pay a prescribed percentage amount. Once the maximum dollar threshold is exceeded, the employer is no longer responsible for additional claim payments and begins to receive reimbursement. This threshold is typically variable and is calculated based on a percentage of the anticipated annual costs. For most companies this expense becomes one more line item to plan around when budgeting small business insurance costs for the year.

Aggregate coverage usually includes medical and dental benefits for full-time employees. It may also cover short-term disability and vision care, with specific terms negotiated at the time of policy purchase. In that sense the policy sits alongside other employer-purchased protections like workers compensation coverage, both of which exist to shield the business from costs tied to its workforce.
