Kraft Heinz, Ralph Lauren, and other major employers have filed a lawsuit against UnitedHealth, alleging the insurer improperly approved and paid inflated, duplicate, and unsupported medical claims using money from their self-funded employee health plans. The employers claim UnitedHealth relied too heavily on automated approvals with limited human review, paid higher rates to providers it owns, and withheld claims data needed for audits and oversight. They are seeking access to their complete claims records, reimbursement for alleged financial losses, and other damages. UnitedHealth disputes the allegations and says it intends to defend itself against the lawsuit. The case highlights growing concerns among employers about claims transparency, third-party administrator oversight, and how healthcare benefit funds are managed.
