CHARLOTTE, N.C. -- Carolinas Healthcare System said its computer system was hacked.
It says the personal information of some 5,600 patients of CMC –Randolph may have been exposed.
CMC discovered the security breach on October 8 following an upgrade to the hospital's security software.
The hacker may have accessed emails dating back to March 11 including some that contained personal information.
Officials said the hackers may have gained access to patient names, dates and times of service, provider and facility names, internal hospital medical record and account numbers, dates of birth, and treatment information, such as diagnosis, prognosis, medications, results and referrals.
Potentially affected patients have been sent personal letters explaining the type of information involved.
At this time, Carolinas HealthCare System has no evidence that the information has been misused, and based on the investigation, no other email accounts or other computer systems (including the electronic medical records system) were found to have been affected by this incident.
The hospital says if you have questions you can call this number at 1-877-313-1404.
