Aetna has launched a new partnership with Mexico's largest health insurer to give about 30,000 people who buy high-end plans access to its provider network both in this country and abroad, Aetna announced Monday. As of Feb. 1, Grupo Nacional Provincial (GNP) customers can use Aetna's network, healthcare management services, mobile technology tools and wellness information. The deal will continue Aetna's goal of expanding its international business in Latin America. "GNP shares our deep commitment to excellence and focus on customer needs," Aetna International General Manager of the Americas Eugene Marks said in the announcement. GNP's CEO Alejandro Bailleres said the arrangement is beneficial for its members because they often have second homes in the United States and travel extensively. Announcement
