Rhode Island Gov. Donald Carcieri announced a plan six months ago to save the state $67 million by transforming the system for providing healthcare to the elderly, poor and disabled. The plan requires a "global Medicaid waiver" from the federal government. The General Assembly even approved a state budget that took the savings into account, but lawmakers and Rhode Island's 186,000 Medicaid recipients have yet to see a written plan. The proposal will likely be submitted to the federal government the end of July or early August, said Department of Human Services Associate Director Murray Blitzer.
