LETTER OF MEDICAL NECESSITY FOR HEREDITARY GYNECOLOGIC CANCER GENETIC TESTING Date: Date of service/claim To: Utilization Review Department Insurance Company Name, Address, City, State Re: Patient Name, DOB, ID # ICD-9 Codes: (list codes) This letter is to urge you to provide coverage for medically-indicated hereditary gynecologic cancer genetic testing for the above named patient. The personal and/or family history reported on the test requisition form raises significant concern for an inherited predisposition to ovarian and/or uterine cancer and indicates a reasonable probability of detecting a causative gene mutation. There are many genes known to predispose to ovarian and/or uterine cancer and the ordered genetic test analyzes 9 high-risk, well characterized genes associated with hereditary gynecologic cancer: BRCA1, BRCA2, EPCAM, MLH1, MSH2, MSH6, PMS2, PTEN, and TP53. These genes substantially increase the risk for ovarian and/or uterine cancer and other cancers. This multi-gene test is the most efficient and cost-effective way to analyze the implicated gynecologic cancer genes and has significant potential to identify a causative gene mutation in the patient. Identification of a causative gene mutation will clarify the patient’s future cancer risk(s) and target medical management. The rationale for testing is that the presence of a mutation in one of these genes places this patient at a substantially increased risk for developing cancer and thus would influence our management recommendations significantly. An aggressive approach to reduce the risk of cancer is indicated in individuals who carry a gene mutation that predisposes them to cancer. If a mutation is identified, we would recommend high-risk management to reduce the patient’s risk of developing an advanced stage cancer and subsequently dying of the disease. As such, I am ordering this genetic test as medically necessary care and affirm that the patient has provided informed consent for genetic testing. Please contact me if I can provide you with additional information.
