Definition:Self-insured plan
📋 Self-insured plan is a benefit program — most commonly for health coverage — in which the sponsoring employer or organization directly finances claims incurred by plan participants rather than paying premiums to an insurance carrier under a fully insured arrangement. The term is functionally synonymous with a self-funded plan and is used interchangeably across much of the insurance and benefits industry, though "self-insured plan" appears more frequently in regulatory and legal contexts.
🔄 Plan sponsors typically hire a third-party administrator (TPA) or use an insurer's administrative services only (ASO) platform to manage enrollment, adjudicate claims, negotiate provider network contracts, and handle compliance filings. Because the employer bears the underwriting risk, most self-insured plans incorporate stop-loss insurance to cap exposure — specific stop-loss protects against any single high-cost claimant, while aggregate stop-loss triggers when total plan claims exceed a predetermined threshold. The employer retains claim-level data ownership, an advantage that enables more sophisticated analytics and population health strategies.
🎯 For the insurance industry, self-insured plans represent both a competitive challenge and a revenue opportunity. On one hand, every employer that moves to self-insurance is a traditional group insurance policy that doesn't renew. On the other, carriers earn substantial fees through ASO contracts and stop-loss underwriting — a line of business that has become one of the fastest-growing segments in employee benefits. Insurtech startups have entered this space with platforms that help smaller employers self-insure for the first time by bundling stop-loss, TPA services, and cost-containment tools into a single offering, further blurring the boundary between fully insured and self-insured models.
