In December 2023, Pope Francis appointed Buco as apostolic administrator of the Diocese of Catarman, simultaneous with the pope's acceptance of the resignation of its bishop, Emmanuel Trance, due to health reasons.[7] He was consecrated as bishop on September 8, 2018.[8] Bishop Francisco de Leon of Antipolo acted as principal consecrator, with bishops Oscar Florencio and Jacinto Jose serving as co-consecrators.[4] For his episcopal ministry, Buco chose the motto, Lex Dei Vitae Lampas (The Law of God is the Lamp of Life), taken from Psalm 19:8 of the Christian Bible.[9]
In October 2024, Buco was subsequently appointed as the third Bishop of Catarman in an announcement made by Pope Francis.[10]
