Definity

Definity Health was a pioneer in the consumer-driven healthcare (CDH) market, recognized for introducing health plans that combined high-deductible insurance with a health reimbursement account (HRA). Founded in 1998, the company focused on empowering members with digital tools and transparent information to manage their own healthcare spending and decisions. Its innovative model sought to reduce employer costs while increasing member engagement in health management. In 2004, Definity Health was acquired by UnitedHealth Group for approximately $300 million, significantly expanding the acquirer's presence in the emerging consumer-driven health plan sector.
