Provide how Medicaid Managed Care will or will not save money for a Medicaid State Agency?
One source should be the website Centers for Medicare and Medicaid.
Hint:  Centers for Medicare and Medicaid bestow the responsibility of the Medicaid program to each state in the nation.  They are provided, through a calculation, a set dollar amount per year of funds from the federal government to cover the beneficiaries of Medicaid (complicated process, summarizing for you).  Ultimately, the state (s) will attempt to keep this program financially viable and managed.
