MINNEAPOLIS, Minn.--(BUSINESS WIRE)--June 2, 2008--AmeriChoice, a UnitedHealth Group (NYSE: UNH) company, today announced it had received all necessary regulatory approvals for its acquisition of Unison Health Plans and the transaction has closed. On a combined basis, AmeriChoice and Unison serve more than two million beneficiaries of government-sponsored health care programs in 21 states and the District of Columbia, including Unison’s operations in Pennsylvania, Ohio, Tennessee, Delaware, South Carolina and Washington, DC.

Dr. John Blank, M.D., Unison’s president and chief executive officer, said, “Our combination with AmeriChoice is a tremendous opportunity for us to work with one of the most respected public sector health care program companies in the country and will give Unison access to assets and resources that will enable even stronger performance on behalf of our members and state sponsors.”

Unison provides government-sponsored health plan coverage to approximately 380,000 people through a network of 28,000 independent health care providers and a workforce of almost 1,000 employees.
