Headquartered at 55 Water Street in Lower Manhattan, New York City,[1] it is a multi-billion-dollar organization with over 3 million members.

[9] The company was founded by David M. Heyman with the support of New York City mayor Fiorello La Guardia, who wanted to offer medical services to New Yorkers of “moderate means.”[10] HIP got its first members in 1947.

[12] Due to their steadily worsening financial condition, the decision was made to merge these entities into HIP, effective March 29, 2006.

[13] ConnectiCare was established in 1981[14] and serves approximately 245,000 members in a service area that includes the entire State of Connecticut; Berkshire, Hampshire, Hampden, Franklin and parts of Worcester counties in Massachusetts; and Westchester, Rockland, Putnam and Orange Counties in New York.

[3][13] Anthony Watson, then chairman and CEO of HIP, managed the 2006 merger, which created the largest health insurer based in New York State.

[18][19] Two additional Neighborhood Care sites were established in Chinatown in December 2013[20] and in Crown Heights in April 2016.

[23] In February 2016, EmblemHealth announced a new partnership with the City of New York and the Municipal Labor Committee to provide expanded access to health care.
