Many lawsuits against employer group health plans hinge on the enforceability of the plan’s anti-assignment provision. ERISA does not give providers the right to sue for plan benefits. A provider’s lawsuit must be derived from the participant’s right to plan benefits. In other words, the participant must assign his or her right to the provider. Even with such an assignment, a provider will lack standing to bring a lawsuit if the ERISA plan has a valid and enforceable anti-assignment clause. (ERISA itself generally prohibits assignment of retirement plan benefits, but the ERISA prohibition on assignment does not apply to health and welfare plans.)
While courts have generally held that anti-assignment provisions are enforceable, states have begun weighing in on the side of providers in an attempt to keep these lawsuits alive. But can a state law invalidate anti-assignment clauses in plans subject to ERISA and mandate that benefits be assignable to a healthcare provider? The Fifth Circuit, in Dialysis Newco, Inc. v. Community Health Systems Group Health Plan, 938 F.3d 246 (5th Cir. 2019), recently invalidated a Tennessee law that sought to do just that.
