Some Illinois lawmakers are pushing for a delay in a pilot program that would place some elderly and disabled Medicaid patients into HMOs. The Illinois Department of Healthcare and Family Services has issued a request for proposals by managed-care plans to provide medical care services to 40,000 seniors and adults with disabilities in suburban Cook, DuPage, Kane, Kankakee, and Will counties. But lawmakers say the state is trying to launch a program before it has been adequately vetted by lawmakers, medical care providers, and other groups, the Chicago Tribune reports.
