Role of Stop-Loss

Stop Loss coverage is an insurance product that provides protection against catastrophic or unpredictable losses.

What is Stop Loss coverage?

Stop Loss coverage is an insurance product that provides protection against catastrophic or unpredictable losses. It is purchased by employers who self-fund their employee benefit plans, but do not want to assume 100% of the liability for losses that exceed certain limits called deductibles.

Types of stop Loss coverage

What is Specific Stop Loss coverage?

What is Aggregate Stop Loss coverage?

What is the role of the employer's plan document?

The plan document defines the benefits offered to the employees and is critical in determining liability under the Stop Loss coverage. Because the employer has freedom in designing the plan, there may be elements in the document that are not included under the Stop Loss coverage. The covered portions of the plan document must be approved by the underwriter in order to go into effect under the Stop Loss coverage. Changes in the plan document after its initial approval must be approved before their inclusion in the Stop Loss coverage by an addendum to the plan document.

How is loss defined?

Expenses are determined to be eligible for reimbursement under the Stop Loss coverage based upon two criteria:

When are claims paid?

Stop Loss coverage is provided on a reimbursement basis. The group is responsible for payment of all losses under a self-funded plan. With the purchase of Stop Loss coverage, the group is still responsible for all losses including those that exceed the deductible. After the losses have been paid, the employer will be reimbursed for the amount of the loss that exceeds the deductible. All reimbursements are paid directly to the employer, never to an employee or to a provider of services or supplies.

When and how are reimbursements paid?

Specific claims are generally submitted and processed as soon as the deductible is met. Aggregate claims are usually processed only after the close of the contract period. Occasionally, there are requests for a "monthly accommodation" on the Aggregate. This means the year-to-date Aggregate claims are compared to the year-to-date Aggregate Deductible to determine if any amount is payable. Funds could change hands during the year. The ultimate amount of the claim should remain the same. There is a business risk in this situation rather than an insurance risk as the employer may have to pay back advances if it turns out that claims in a later month would not have been reimbursed.


Self-funding and Stop Loss coverage provide an effective strategy to protect employers against catastrophic losses, while maintaining plan design flexibility and maximizing cost savings in comparison to the traditional fully-insured model.
