Fam hx of malig neoplm of lymphoid, hematpoetc and rel tiss

This code indicates a family history of malignant neoplasms affecting the lymphatic system, blood-forming tissues, or other related systems, excluding Hodgkin's lymphoma and non-Hodgkin's lymphoma, which have their own specific family history codes. It signifies a genetic predisposition or increased risk for these types of cancers in a patient due to their family's medical history.

Use this code when a patient reports a first-degree or second-degree relative (e.g., parent, sibling, child, grandparent) who has been diagnosed with a malignant neoplasm of lymphoid, hematopoietic, or related tissues, other than Hodgkin's or non-Hodgkin's lymphoma. This is often documented during a patient's initial comprehensive history and physical examination or during follow-up visits where risk factors are assessed.

• Always sequence this code as a secondary diagnosis, as it describes a risk factor, not the patient's current condition.
• Ensure the documentation clearly specifies "family history" and the type of cancer falls within the "other malignant neoplasms of lymphoid, hematopoietic and related tissues" category.
• Do not use this code if the patient themselves has a personal history of such a malignancy; instead, use the appropriate personal history code (e.g., Z85.79).
