Malignant neoplasm of hard palate

This code signifies a primary cancerous tumor originating in the hard palate, the bony anterior portion of the roof of the mouth. It represents an uncontrolled growth of abnormal cells within the hard palate tissue, which can invade surrounding structures and potentially metastasize.

Use this code when documentation confirms a primary malignant neoplasm located specifically in the hard palate. This diagnosis is typically established through biopsy and histopathological examination. Supporting documentation will include pathology reports, physician notes detailing the tumor's location, and imaging studies confirming the site.

• Differentiate from malignant neoplasms of the soft palate (C05.1) or uvula (C05.2).
• Always confirm the primary site; if metastatic to the hard palate, a secondary malignant neoplasm code (C79.x) would be appropriate, along with the primary site.
• Ensure laterality, if applicable and documented, is not confused with this site-specific code.
