Malignant neoplasm of hard palate

This code signifies a cancerous tumor originating in the hard palate, the bony anterior part of the roof of the mouth. It represents a primary malignancy of the palatine bone and associated tissues.

Apply this code when documentation explicitly states a diagnosis of malignant neoplasm of the hard palate. This is typically supported by pathology reports confirming malignancy and specifying the hard palate as the primary site.

• Ensure the documentation specifies "hard palate" and not other oral cavity sites.
• Do not confuse with malignant neoplasms of the soft palate (235.1) or unspecified palate (145.9).
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
