DALLAS - The Employee Retirement Income Security Act preempts a health plan's action seeking subrogation from several insurers under the plan's coordination of benefits (COB) provision of benefits it paid to its participants, even though ERISA would not preempt a subrogation action brought by the participants, a federal judge in Texas ruled June 13 (Central States, Southeast and Southwest Areas Health and Welfare Fund v. Health Special Risk, Inc., et al., No. 3:11-CV-2910-D, N.D. Tex.; 2013 U.S. Dist. LEXIS 83400).
