Coscolluela, who has served Ogilvy over 14 years with a spell in Thailand as well as the Philippines, will move to a non-executive chairman role, effective January next year.
Randy Aquino, the 4As president who joined Ogilvy from BBDO Guerrero Ortega in March, will take on her role, reporting to Tim Isaac, Ogilvy Asia Pacific's vice chairman.
Coscoluella commented: "Randy is a wonderful person, both professionally and personally. I am confident that his leadership will bring Ogilvy Philippines to even greater heights."
The agency has yet to confirm a replacement head of Ogilvy Advertising.
