Malignant neoplasm of unspecified fallopian tube

This code signifies a primary cancerous tumor originating in a fallopian tube, where the specific side (left or right) is not documented. It represents an uncontrolled growth of abnormal cells within the fallopian tube tissue.

This code is appropriate when the medical record explicitly states a malignant neoplasm of the fallopian tube but does not specify laterality. It is used when pathology confirms malignancy and the physician's documentation indicates an unspecified fallopian tube as the primary site.

• Avoid using this code if laterality (left or right fallopian tube) is documented; instead, select the more specific code.
• Ensure documentation clearly indicates a primary malignancy, not a metastatic site.
• Always review pathology reports and operative notes for precise anatomical location and laterality.
