Horizon Blue Cross Blue Shield of New Jersey named Kevin P. Conlin to succeed Robert A. Marino as chief executive of New Jersey's largest health insurer effective Jan. 1, the Newark company said Thursday.

Marino has been Horizon's president and CEO since March 2011 and chairman since March 2012. He is retiring on Dec. 31.

Conlin joined Horizon in 2012 as executive vice president for health care management and has led the company's efforts to get away from the legacy fee-for-service model, under which doctors and hospitals are paid for the volume of services they provide rather than for the results.
