Behavioral Health Systems currently delivers and manages mental health and chemical dependency services to approximately 120,000 lives in the Greater Chicago Metropolitan area, Central Illinois, northwestern Indiana, and Cleveland and Toledo, Ohio, through 28 contracts. About 46 percent of these lives are covered on a full-risk capitation basis, with Behavioral Health Systems assuming both the institutional and the practitioner risks. About 44 percent of the managed lives are covered by partial risk contracts for practitioner risk only. Behavioral Health Systems serves the remaining 10 percent of its members through nonrisk contracts that combine utilization management and a preferred provider organization. Clients include a hospital (for its employees and their dependents), three health maintenance organizations (HMOs), three independent practice associations (IPAs), six physician-hospital organizations, several manufacturing companies, and the archdiocese of Chicago.
