Anthem Blue Cross and Blue Shield is warning 10,000 New Hampshire physicians, dentists and other providers that their Social Security numbers may have been stolen.

The insurance company said the providers' numbers may be in a file that a national-level employee transferred to a personal laptop computer that was later stolen.

The Blue Cross Blue Shield Association said the employee's actions violated the association's security policies and was unauthorized.

Anthem spokesman Christopher Dugan said the security breach occurred at a national level and did not include any information about New Hampshire members or their medical conditions.

The association is offering affected providers free credit monitoring for one year.
