The job stop-loss does
A self-funded employer pays its plan's claims directly — which works beautifully until one member needs a transplant or a premature infant spends months in the NICU. Stop-loss insurance (sometimes called excess loss insurance) is the policy that caps that exposure: the employer funds claims up to agreed thresholds, and the carrier reimburses what exceeds them.
Stop-loss is insurance for the employer, not for employees. Members never interact with it; their benefits come from the plan itself. What stop-loss protects is the company's balance sheet — turning a theoretically unlimited liability into a bounded, budgetable one.
Specific vs. aggregate coverage
Stop-loss comes in two layers, usually purchased together:
- Specific (individual) stop-loss caps the plan's exposure to any single member's claims in a policy year. If the specific deductible is $75,000 and one member's claims hit $400,000, the plan pays the first $75,000 and the carrier reimburses the rest. Specific deductibles commonly range from tens of thousands for smaller groups into the hundreds of thousands for large, risk-tolerant plans.
- Aggregate stop-loss caps the plan's total claims across all members, typically set at around 120–125% of expected claims (the "attachment point"). It protects against a bad year of many mid-sized claims rather than one catastrophic case.
Together they bound both tails: specific handles severity, aggregate handles frequency. Level-funded plans bundle both layers tightly, which is what makes self-funding mechanics workable for small groups.
What drives stop-loss pricing — and what to watch in the contract
Stop-loss underwriters price on census demographics, industry, plan design, chosen deductibles, and — above all — the group's claims experience and known high-cost conditions. Terms that deserve attention:
- Lasering: carriers may set a higher specific deductible for a named individual with known ongoing claims. Ask whether the quote lasers anyone and whether renewals can add lasers.
- Contract basis (run-in/run-out): "12/12," "12/15," "15/12" and similar terms define which incurred-vs-paid claim windows are covered. Mismatched bases create coverage gaps at transitions.
- Renewal caps and no-new-laser guarantees: available from some carriers, valuable in volatile years.
- Captive arrangements: mid-sized employers increasingly join stop-loss group captives — pooling a layer of risk with other employers to smooth volatility and share underwriting profit, one reason "captive insurance" keeps coming up in self-funded circles.
The strategic point: stop-loss pricing is where your plan's claims record turns into next year's fixed costs. An employer whose cost containment program genuinely reduces claims — fewer escalated episodes, fewer avoidable ER visits, earlier catches on brewing conditions — brings a better story to underwriting every single year.
Stop-loss and everyday claims: the connection people miss
Stop-loss protects against catastrophe, but catastrophe is priced from the everyday. Underwriters read a plan's routine utilization — ER rates, unmanaged chronic conditions, gaps in access — as the leading indicators of future large claims.
That's one of the quieter benefits of an access model like EZaccessMD: 24/7 physician access with in-home diagnostics doesn't just redirect avoidable facility claims; it gets symptoms evaluated earlier — the fever that's actually pneumonia, the "indigestion" that warrants an EKG — with physician follow-up rather than a discharge summary. Fewer escalations is exactly the trend line a stop-loss renewal wants to see. Model the claims-side impact with the ROI calculator.
