Illinois Gov. Pat Quinn plans to announce six partnerships aimed at controlling health costs by eliminating unneeded care for to up to 6,000 Medicaid recipients.

The collaborations to be announced Tuesday will help Illinois comply with a 2011 state law requiring that at least 50% of Illinois Medicaid recipients be moved into managed care by 2015.

The project is aimed at the costliest patients for Medicaid - the elderly and disabled.

A spokesman for the Illinois Medicaid agency tells The Associated Press that the collaborations include four groups in northeastern Illinois and two in central Illinois.

The Macon County Mental Health Board in Decatur will lead one partnership. Others include a nonprofit network on Chicago's South Side and a group involving a company that manages several Chicago nursing homes.
