Definition:Self-funded health plan
🏥 Self-funded health plan is an arrangement in which an employer assumes direct financial responsibility for paying its employees' health insurance claims rather than purchasing a fully insured policy from an insurance carrier. Sometimes called a self-insured health plan, this model allows the employer to retain the premium dollars that would otherwise flow to an insurer, bearing the underwriting risk itself while typically hiring a third-party administrator (TPA) to handle claims processing, network access, and plan administration.
⚙️ Under this structure, the employer establishes a trust or dedicated fund from which claims are paid as they arise. To protect against catastrophic or unexpectedly high aggregate claims, most self-funded employers purchase stop-loss insurance — both specific stop-loss, which caps exposure on any single claimant, and aggregate stop-loss, which limits total plan-year liability. Because self-funded plans are regulated primarily under the federal Employee Retirement Income Security Act (ERISA), they are generally exempt from state insurance mandates, premium taxes, and many state-level benefit requirements — a regulatory distinction that heavily influences the decision to self-fund.
💡 The prevalence of self-funded plans reshapes the competitive landscape for carriers and insurtech firms alike. Large employers have increasingly moved to self-funding over the past several decades, meaning that insurers often compete for administrative-services-only (ASO) contracts and stop-loss policies rather than traditional fully insured business. For MGUs and specialty carriers, the growing stop-loss market has become a significant growth area. Meanwhile, data-driven startups are targeting self-funded employers with tools for predictive analytics, cost containment, and population health management, recognizing that these employers have both the financial incentive and the data access to invest in innovative solutions.
