Following the 1992 separation of five districts from Det Udom: Thung Thoeng, Nong Om, Na Kasem, Khok Chamrae, and Kut Ruea to form a minor district (king amphoe) called "Thung Si Udom," some communities in tambon Thung Thoeng preferred to remain affiliated with the original district, so the central government decided to split the tambon into two portions, the upper portion of which is now Thung Thoeng and was transferred back to Det Udom in the following year, while the lower region, which consisted of nine villages, was formed a new subdistrict called "Na Hom," and has been governed by Thung Si Udom since then. After its establishment, the tambon was governed by the Subdistrict Council of Na Hom, until May 25, 1997, when the council was upgraded by the  to be the Subdistrict Administrative Organization of Na Hom.
