When you are questioned in custody in connection with a crime, you are told that anything you say may be used against you. When you are questioned in your healthcare provider's office, you are often asked to sign an information release and even if you aren't, you are led to believe that HIPAA will protect your information. What rarely crosses our minds is that there are exceptions to statutes that protect this information, a court may order release of medical records, other treating or evaluating health care professionals have access to this information, and you may someday be applying for disability or be involved in a lawsuit in which medical records will be essential. All that before broaching the topic of insider access to records, hackers, "accidental" or "unintentional" release as claimed by the CA attorney general, and security clearance investigation.
Be honest with your physician, but think before you speak, because we live in an age where information is bought, sold, and used against us in ways we could never imagine 30 years ago.
