How it started
History
AmeriHealth, known initially as Delaware Valley HMO, was established in 1995 to provide health coverage to Pennsylvania employers and their staff residing in Burlington, Camden, Gloucester, and Salem counties of New Jersey. It expanded its coverage area to include southern New Jersey and Delaware, and by 1997, AmeriHealth offered coverage to the entire state of New Jersey. In 2013, AmeriHealth announced it would be offering plans in New Jersey on the federally run health insurance exchange.
