The two companies have announced a new agreement on a Medicaid Health Plan contract for 2018. If you are currently covered by the Amerigroup Medicaid plan, you do not need to make any changes to your plan in order to continue using Unity Point Health. Unity Point Health operates hospitals in Marshalltown and Grinnell, among its locations in Iowa.
