Employers are increasingly considering self-funding for health care to control costs, as traditional fully insured plans become more burdensome due to rising health care expenses and regulations from the Affordable Care Act. Self-funding can lead to savings through tax avoidance, greater flexibility in plan design, and better cost transparency, but it also brings risks associated with unpredictable claims costs. Stop-loss insurance can mitigate these risks by covering excessive individual and aggregate claims, making self-funding a viable option for employers if managed correctly.
