Ever since Kentucky rapidly shifted patients from traditional Medicaid to private health plans that manage their care for a set price, problems have been widespread. Patients complain of being denied treatment or forced to travel long distances to find a doctor or hospital in their plan's network. Advocates for the mentally ill argue the care system for them has deteriorated. And hospitals and doctors say health plans have denied or delayed payments. Experts warn that what happened in Kentucky should be a cautionary tale for other states that rush to switch large numbers of people in Medicaid, the state-federal program for the poor and disabled, to managed care in hopes of cutting costs and improving quality.
