Personal history of malignant neoplasm of liver

This code indicates a patient's past history of a primary malignant tumor that originated in the liver. It signifies that the patient has been definitively diagnosed with and treated for liver cancer, and there is no current evidence of the disease. This history is relevant for ongoing surveillance, risk assessment, and treatment planning for other conditions.

Use this code when documenting a patient's medical history for follow-up appointments after successful treatment for liver cancer, or when the history of liver malignancy impacts the management of current, unrelated conditions. It is appropriate when the primary liver cancer is no longer active and the patient is considered to be in remission or cured.

• Do not use this code if the patient has active liver cancer; instead, code the specific type of liver malignancy.
• This code is appropriate for both hepatocellular carcinoma and cholangiocarcinoma that originated in the liver.
• Always sequence this code as a secondary diagnosis, as it represents a historical condition, not a current illness requiring active treatment.
