Personal history of malignant neoplasm of tongue

This code indicates that a patient has a past medical history of a malignant tumor originating in the tongue. It signifies that the primary cancer of the tongue has been successfully treated and is no longer present, but the patient requires ongoing monitoring for recurrence or late effects.

This code is used when documenting follow-up care for a patient who has completed treatment for tongue cancer, such as surgery, radiation, or chemotherapy. It is appropriate for surveillance visits, management of long-term side effects, or when the patient presents for unrelated conditions but their history of tongue cancer is relevant to their overall care.

• Always sequence this code as a secondary diagnosis, as it represents a historical condition.
• Do not use this code if the patient currently has active tongue cancer; instead, code the active malignancy.
• Ensure documentation clearly states the malignancy is no longer present to support the use of a "personal history" code.
