Dr. Hankyu Chung of San Jose, Calif., recently began notifying all of his patients that a burglary may have exposed their personal health information and personally identifiable information.

On June 17, 2013, burglars entered the building complex in which Dr. Chung's office is located by opening an unlocked door, then accessed Dr. Chung's office via the crawl space above the office itself. No locked doors or windows were breached.

Among the items stolen were two laptops, one of which was used solely to access the Internet. The second laptop, which was password-protected, contained all patients names, telephone numbers, birthdates and medical records, including visit dates, complaints, physical examination notes, diagnoses, and testing and medication information.

"The circumstances that resulted in this breach are being corrected through increased security and implementation of procedures to minimize the possibility of future breaches," Dr. Chung wrote in the notification letter [PDF].

While no identity theft protection services are being offered to affected patients, all patients are being advised to review their credit information frequently over the next few months.
