Segment Information

Centene operates in two segments: Managed Care and Specialty Services.  

The Managed Care segment consists of Centene’s health plans including all of the functions needed to operate them. The Specialty Services segment consists of Centene’s specialty companies offering auxiliary healthcare services and products. Factors used in determining the reportable business segments include the nature of operating activities, the existence of separate senior management teams, and the type of information presented to the Company's chief operating decision-maker to evaluate all results of operations.

In January 2017, the Company reclassified Cenpatico Behavioral Health of Arizona, LLC and the related Cenpatico Integrated Care health plan from the Specialty Services segment to the Managed Care segment due to a reorganization of the Arizona management structure following the Health Net integration. As a result, the financial results of Cenpatico Behavioral Health of Arizona, LLC and the related Cenpatico Integrated Care health plan have been reclassified from the Specialty Services segment to the Managed Care segment for all periods presented.
