Segment Reporting [Abstract]  
Segments Segments
We currently have four reportable segments consisting of: 1) Medicaid; 2) Medicare; 3) Marketplace; and 4) Other. Our reportable segments are consistent with how we currently manage the business and view the markets we serve.
The Medicaid, Medicare, and Marketplace segments represent the government-funded or sponsored programs under which we offer managed healthcare services. The Other segment, which is insignificant to our consolidated results of operations, includes long-term services and supports consultative services in Wisconsin and the
commercial portion of the business acquired in connection with the ConnectiCare transaction that closed effective February 1, 2025.
The key metrics used to assess the performance of our segments are revenue, margin and medical care ratio (“MCR”). MCR represents the amount of medical care costs as a percentage of premium revenue. Therefore, the underlying margin, or the amount earned by the segments after medical or service costs are deducted from revenue, represents the most important measure of earnings reviewed by management, and is used by our chief executive officer, who is our chief operating decision maker, to review results, assess performance, and allocate resources. Such oversight and decision making includes, among others, pricing, approving capital expenditures, and identifying growth opportunities. We do not report total assets by segment since this is not a metric used to assess segment performance or allocate resources.
