The critical role of ERISA in state health reform.

Despite prominent roles for employers and state regulation in the Clinton administration's Health Security Act, relatively little attention has been accorded to the impact of federal preemption of state legislation through the Employee Retirement Income Security Act (ERISA). As interpreted by the U.S. Supreme Court, ERISA permits state regulation of insured employee health plans but otherwise preempts analogous regulation relating to self-insured benefit plans. This has prompted lower courts to find that hospital rate-setting legislation, regulation of preferred provider organizations (PPOs), and medical malpractice suits for utilization review decisions are preempted by ERISA. Several issues with major implications for health reform remain unresolved, such as the availability of ERISA preemption to self-insured health alliances and health maintenance organizations (HMOs).
