Genetic susceptibility to other malignant neoplasm

This code indicates a patient has an inherited predisposition to developing various types of cancer, excluding breast and ovarian cancers. This susceptibility is often identified through genetic testing revealing specific mutations or a strong family history of multiple cancer types. It signifies an increased risk, not a current diagnosis of cancer.

Use this code when a patient has a documented genetic mutation (e.g., Lynch syndrome, Li-Fraumeni syndrome) that increases their risk for malignant neoplasms other than breast or ovarian. It is also appropriate for individuals with a significant family history suggestive of a hereditary cancer syndrome, even if specific genetic testing is pending or inconclusive. This code is typically used for screening, surveillance, or counseling encounters.

• Always sequence this code as a secondary diagnosis when a primary reason for the encounter (e.g., screening colonoscopy) is present.
• Do not use this code if the patient has an active malignant neoplasm; instead, code the specific cancer and any relevant personal or family history codes.
• Ensure documentation clearly supports the genetic susceptibility, such as genetic test results or detailed family history.
