Diaz v. Blue Cross & Blue Shield
Annotate this CaseBlue Cross and Blue Shield of Montana (BCBS) and New West Health Services (collectively TPAs) administered a self-funded employee healthcare benefit plan for the State's employees. Jeannette Diaz and Leah Hoffmann-Bernhardt (Plaintiffs), who were both injured in accidents, filed suit against the state, BCBS, and New West for allegedly violating their made-whole rights by failing to conduct a made-whole analysis before exercising subrogation rights. Plaintiffs moved for class certification seeking to include in the lawsuit individuals who had their benefits reduced under the State plan, as well as individuals who had their benefits reduced under policies independently issued and administered by the TPAs. The district court denied class certification and determined that Montana's made-whole laws did not apply to TPAs. The Supreme Court (1) affirmed the district court's finding that BCBS and New West, in their capacities as TPAs in the present case, were not subject to the made-whole laws under either the subrogation statutes or under a third-party beneficiary theory; and (2) reversed the district court denial of class certification, as Diaz and Hoffmann-Bernhardt demonstrated that the requirements of Mont. R. Civ. P. 23 were met.
