Prsnl hx of malig neoplm of nasl cav, mid ear, & acces sinus

This code indicates that a patient has a past medical history of a malignant tumor originating in the nasal passages, middle ear, or paranasal sinuses. While the primary cancer is no longer present or active, its history remains relevant for ongoing patient care, surveillance, and risk assessment.

This code is appropriate for patients who have completed treatment for a malignant neoplasm of the nasal cavities, middle ear, or accessory sinuses and are now considered to be in remission or cured. It should be used for follow-up visits, surveillance, or when the history of this cancer impacts current treatment decisions for other conditions.

• Always sequence this code as a secondary diagnosis, as it represents a historical condition, not an active disease.
• Do not use this code if the patient has active cancer in these sites; instead, code the active malignancy.
• Ensure documentation clearly states the patient's history of cancer in the specified anatomical sites and that it is no longer active.
