K09.9
ICD-10-CMThis code represents a non-specific cystic lesion found within the oral cavity or surrounding structures, such as the jaw, salivary glands, or soft tissues of the mouth. It indicates the presence of a fluid-filled sac without further pathological or anatomical detail.
Use this code when documentation identifies a cyst in the oral region but lacks specific information regarding its type, origin, or precise location (e.g., "oral cyst," "cyst of mouth"). This code is appropriate when the provider has not specified a more definitive diagnosis after initial examination or imaging.
