Most, if not all, ERISA health insurance plans state that injuries caused by a liable third party are not a covered expense and require reimbursement when a plan pays for injury-related medical expenses (often referred to as subrogation clauses). ERISA provides that health plans which qualify under its provisions can bring a civil action under section 502(a)(3) to obtain equitable relief to enforce the terms of the plan. Appropriate equitable relief is really the only enforcement mechanism an ERISA plan can utilize to address its reimbursement rights contained in the plan.
