To ensure your health data is secure, use strong passwords if you store health information on your computer or mobile device, and always check the source before providing medical information online, suggests HealthIT.gov. When not in use any more, shred all health-related information, including physician statements, prescriptions and insurance forms.
File a complaint with your health insurance provider if you suspect someone used or shared your private information and breached the Health Insurance Portability and Accountability Act or HIPAA rules, states HealthIT.gov. Insurance providers typically send a notice of privacy practices to help policyholders file a complaint. Alternatively, file a complaint with the attorney general office in your state or the U.S. Department of Health and Human Services Office for Civil Rights. The Federal Trade Commission handles complaints related to websites not covered by HIPAA that shared their users' health information inappropriately.
