Threat actors can leverage stolen medical records to impersonate legitimate patients to commit various forms of fraud, including submitting fraudulent claims to health insurers without authorization. This could not only affect healthcare coverage, but also compromise safety if there’s misinformation on file that is needed for medical treatment. Anyone who may have been a victim of a medical data breach should get confirmation from their provider to find out exactly what information was stolen. Change and strengthen any online logins and implement multi-factor authentication. Asking the insurance provider for copies of claims and carefully reviewing explanation of benefits notices can reveal if a patient’s identity has been used fraudulently. This might show if inaccurate health and medical information is present in the patient’s records. Lastly, financial and credit accounts should be monitored closely, because sometimes medical insurance information is used to commit other forms of financial fraud. Placing a credit freeze on file with the credit bureaus and notifying banks or other financial institutions is helpful to prevent fraud when identity theft is suspected.
