Definition of Aggregate Stop-Loss Insurance

Aggregate stop-loss insurance is a form of insurance coverage that protects businesses or benefit plans from excessive losses due to high claims costs.

It serves as a financial safety net by setting a maximum limit on the total claims expenses that a business or plan will bear in a specific policy period, typically one year.

In the context of employee benefits, self-insured employers assume the risk of paying for their employees' healthcare expenses directly, rather than purchasing traditional fully-insured health insurance plans.

To mitigate the financial risks associated with high claim costs, employers often opt for aggregate stop-loss insurance.

With aggregate stop-loss insurance, the insurance provider reimburses the employer for claims costs that exceed a pre-established threshold known as the "attachment point" or "specific deductible."

This threshold is set based on the employer's risk tolerance and the desired level of protection. Once the total claims expenses for all covered employees reach or exceed the attachment point, the aggregate stop-loss coverage kicks in, limiting the employer's financial liability.

The aggregate stop-loss policy typically sets an additional limit called the "aggregate limit" or "maximum liability." This limit represents the maximum amount that the employer will be responsible for in claims costs within the policy period.

If the total claims expenses exceed the aggregate limit, the insurance company assumes liability for the excess amount.

Aggregate stop-loss insurance protects employers from the financial impact of catastrophic or unexpectedly high claims, ensuring that they are not solely responsible for covering all claims costs beyond a certain threshold.

It provides a level of predictability and stability in managing healthcare expenses, especially for self-insured employers who bear the risk of large claim fluctuations.
