Question: Can we submit a BRCA-1 mutation as a diagnosis? New York Subscriber Answer: There is no specific code for BRCA-1 mutations. You first need to determine if your physician was treating the patient for breast cancer or ovarian cancer. Accordingly, you can submit code V84.01 (Genetic susceptibility to malignant neoplasm of breast) for genetic susceptibility to breast cancer and code V84.02 (Genetic susceptibility to malignant neoplasm of ovary) for genetic susceptibility to ovarian cancer. Another option is to submit code 758.9 (Conditions due to anomaly of unspecified chromosome) for conditions due to anomaly of unspecified chromosome. These codes map to codes Z15.01 (Genetic susceptibility to malignant neoplasm of breast), Z15.02 (Genetic susceptibility to malignant neoplasm of ovary), and Q99.9 (Chromosomal abnormality, unspecified), respectively, in ICD-10
