RALEIGH — The personal data for an estimated 1,182 North Carolina medical providers went missing after computer memory stick went missing, the state Department of Health and Human Services announced Friday.

The data was stored on a USB thumb drive by Computer Sciences Corp, a state health department vendor. The company reported the breach to the state and promised a full investigation, according to a statement.

No patient information was contained on the device. But provider data included names, Social Security numbers, dates of birth and addresses in an encrypted format.

All providers involved in the breach were listed in the Medicare exclusion database, which designates those prohibited by the federal government from participating in Medicare, Medicaid and all other federal programs.

“We expect our vendors to maintain the security of information,” said DHHS Secretary Aldona Wos in a statement. “I have instructed CSC that North Carolina expects an independent third party assessment to assure CSC’s adherence to required security standards.”

Providers who have questions can contact a dedicated CSC information hotline at 1-800-957-7154.
