Health Care Service Corporation (HCSC), founded in 1936, is the largest customer-owned health insurer in the United States. The company serves more than 27 million people across five states: Illinois, Montana, New Mexico, Oklahoma, and Texas. With over 35,000 employees, HCSC operates as a mutual legal reserve company, meaning it serves the interests of its members rather than external shareholders.
HCSC's product portfolio includes comprehensive health coverage for employers of all sizes, individuals and families, as well as Medicare and Medicaid plans. The company also offers pharmacy solutions, life insurance, dental insurance, and health data technology services.
The organisation's stated priorities are expanding access to quality, cost-effective healthcare, improving affordability, and empowering member health. For those in AI and data roles, HCSC's scale - serving tens of millions of members - generates substantial healthcare data, and the company's health data technology division signals active investment in data-driven approaches to care delivery and operational efficiency.
