Wausau Benefits

Wausau Benefits was a prominent Third Party Administrator (TPA) that provided health benefit plan administration and management services to self-funded employers. Founded in Wausau, Wisconsin, the company specialized in claims processing, customer service, and cost-containment strategies for healthcare plans. Over its history, it became one of the largest independent TPAs in the United States, serving a diverse range of corporate clients. The company was eventually acquired by Fiserv in 2003 and later became part of UnitedHealth Group's TPA division, UMR, in 2008. Today, its legacy operations and expertise are fully integrated into UnitedHealthcare's broader healthcare services infrastructure. Its service offerings historically included medical, dental, and vision plan administration, as well as disability and life insurance management.
