About the C00–C14 Code Range
ICD-10 codes C00-C14 classify malignant tumors found in the lip, oral cavity, and pharynx. These codes specify the location and type of cancer such as the lip, tongue, gums, mouth floor, palate, tonsils, salivary glands, nasopharynx, and hypopharynx.
Each code within this range helps identify particular cancers like squamous cell carcinoma of the lip's vermilion border (e.g., C00.0 and C00.1), or malignant neoplasms of regions such as the base of tongue (C01), hard and soft palate (C05.0, C05.1), and major salivary glands (C07-C08). Synonyms including "primary carcinoma of upper lip," "carcinoma of base of tongue," and "mucoepidermoid carcinoma of parotid gland" guide coders in matching clinical terms to specific codes. Codes like C09 and C10 cover tumors of tonsils and oropharynx, while C11 addresses nasopharyngeal cancers. The category also covers less defined sites (C14) to capture overlapping or unspecified malignant neoplasms in oral and pharyngeal regions.
