Family history of primary malignant neoplasm (Z80)

The ICD-10 code Z80 series is used to document a family history of primary malignant neoplasms, indicating that a patient's relatives have had various types of cancer. These codes help healthcare providers assess hereditary cancer risk based on family medical history.

The main code Z80 covers any family history of malignant neoplasms, while more specific codes classify histories related to particular organ systems. For example, Z80.0 pertains to digestive organ cancers such as colorectal and gastric cancer, often linked to terms like "family history of colorectal cancer" or "hereditary nonpolyposis colon cancer." Codes like Z80.3 specify family history of breast cancer, including early-onset cases in close relatives. Similarly, Z80.41 to Z80.49 cover various genital organ cancers such as ovarian or prostate cancer, reflecting synonyms like "family history of neoplasm of ovary" or "family history of malignant neoplasm of prostate." The section also includes codes for family history of urinary tract malignancies (Z80.5), leukemia (Z80.6), lymphoid and hematopoietic cancers (Z80.7), other organ systems (Z80.8), and unspecified malignant neoplasms (Z80.9). These codes guide clinical risk evaluation and preventive care for individuals with a hereditary predisposition to cancer.
