Personal history of malignant neoplasm of brain

This code indicates that a patient has a past medical history of a malignant tumor originating in the brain. This diagnosis signifies that the primary brain cancer has been successfully treated and is currently in remission or no longer present. It is used to document the long-term health implications and surveillance needs associated with a prior brain malignancy.

This code is appropriate for patients who have completed treatment for a primary malignant brain neoplasm and are now being seen for follow-up, surveillance, or for treatment of unrelated conditions. It should be used when the patient no longer has active brain cancer but the history is relevant to their current care. Do not use this code if the patient has active or recurrent brain cancer.

• Always sequence this code after the code for the current encounter's primary reason for visit.
• Do not use this code if the patient is currently undergoing active treatment for the brain malignancy or if there is evidence of recurrence.
• Distinguish this from a personal history of benign brain neoplasm, which has a different Z code.
