Segment Reporting [Abstract] |
Segment Information | 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. The health plan in Massachusetts, operated by our individual health insurance business, is included in the Specialty Services segment. Factors used in determining the reportable business segments include the nature of operating activities, 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 2013, the Company reclassified the health plan in Arizona, which is primarily a LTC operation, to the Managed Care segment. As a result, the financial results of the Arizona health plan have been reclassified from the Specialty Services segment to the Managed Care segment for all periods presented.
