Family history of leukemia

This code indicates a patient's family history of leukemia, meaning a blood relative has been diagnosed with any form of leukemia. It signifies a genetic predisposition or increased risk for the patient due to familial occurrence of this hematologic malignancy.

This code is appropriate when documenting a patient's family history of leukemia, particularly during preventative care, risk assessment, or when evaluating symptoms that could be related to a hematologic disorder. It is used to flag a potential genetic component influencing the patient's health.

• Always specify the type of leukemia if known and documented in the family history (e.g., acute myeloid leukemia, chronic lymphocytic leukemia) for more precise risk assessment, though this code is general.
• Do not use this code if the patient themselves has a personal history of leukemia; use the appropriate personal history or active leukemia code.
• This code is for family history only and does not indicate the patient currently has or has ever had leukemia.
