The Mount Kisco Medical Group has joined the MVP Health Care network to provide services to Medicare Advantage customers in Westchester, Putnam, Dutchess, Ulster and Columbia counties, the two companies jointly announced on Monday.
Founded in 1946, the Mount Kisco Medical Group includes more than 300 physicians at 30 offices in Westchester, Putnam and Dutchess counties. The multispecialty group practice will add 150 clinicians at nine locations as of Jan. 1, when physicians of the Mid-Hudson Medical Group are expected to individually join the Mount Kisco Medical Group after its  acquisition of the Mid-Hudson group practice headquartered in Fishkill.
Based in Schenectady, the nonprofit MVP Health Care provides health insurance plans to more than 700,000 members in New York, Vermont and New Hampshire and maintains a regional network of 19,000 health care providers.
