Definition:Specific stop-loss
🛡️ Specific stop-loss is a reinsurance mechanism used in self-insured and stop-loss arrangements that caps the amount a plan sponsor or self-funded employer pays on any single covered claim. Rather than limiting aggregate exposure across an entire book, specific stop-loss sets a per-claimant threshold — often called an attachment point — beyond which the stop-loss carrier reimburses the excess. This tool is fundamental in group health and employee benefits markets where employers assume direct responsibility for claim payments.
⚙️ When an employer self-funds its health plan, it bears the financial risk of each employee's medical costs up to a predetermined dollar amount — the specific deductible. If a single claimant's eligible expenses exceed that threshold during the policy period, the specific stop-loss coverage kicks in and the carrier pays the overage, subject to policy terms. The specific deductible is calibrated based on the employer's size, risk tolerance, and historical claims experience, and it is typically reviewed at each renewal. Third-party administrators play a key role in tracking individual claim accumulations and filing timely notices with the stop-loss insurer once a claimant approaches the threshold.
💡 Without specific stop-loss protection, a single catastrophic claim — such as a premature birth, organ transplant, or advanced cancer treatment — could devastate an employer's benefit fund. By transferring the tail risk of high-cost individual claims to a stop-loss insurer, employers gain the cost advantages of self-funding while avoiding potentially ruinous single-claim exposure. This makes specific stop-loss one of the cornerstones of the self-funded insurance ecosystem and a significant line of business for carriers and MGUs that specialize in medical stop-loss.
