Segment Reporting [Abstract]  
Segment Information Segment Information
The Company operates in four segments: (1) a Medicaid segment, (2) a Medicare segment, (3) a Commercial segment and (4) an Other segment. The Medicaid, Medicare and Commercial segments primarily represent the government-sponsored or subsidized programs under which the Company offers managed healthcare services. The Other segment includes the Company's pharmacy operations, vision and dental services, clinical healthcare, behavioral health, and corporate management company, among others.

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 (CODM) to evaluate all results of operations. The Company's CODM is its Chief Executive Officer. The Company's CODM focuses primarily on each segment's ability to generate sufficient revenues and manage expenses associated with health benefits and cost of services (including estimated costs incurred). As such, the CODM measures operating performance at the segment level based on gross margin, including evaluation of budget to actual variances, to determine the allocation of financial and capital resources for each segment. The Company does not report total assets by segment since this is not a metric used by the Company's CODM to allocate resources or evaluate segment performance.

Segment information for the three months ended March 31, 2025, is as follows ($ in millions):
