View Notice to Impacted Members PDF Document

On Sept. 9, Blue Cross and Blue Shield of Montana (BCBSMT) learned that unauthorized users gained access to Excellus BlueCross BlueShield's systems. Excellus is a member of the Blue Cross and Blue Shield Association and operates in upstate New York.

Excellus reported on Sept. 9 that personal data may have been accessed by unauthorized individuals. The data may have included name, address, telephone number, date of birth, Social Security number, member identification number, financial account information, and medical claims information.

We are working with Excellus to determine to what extent any of our members' data was accessed. For example, members may have been impacted if they sought treatment in Excellus' service area, which includes 31 counties in upstate New York. In these instances, notifications will be sent as appropriate.

Excellus has said it is providing two years of free identity theft protection services to impacted members. For members who think they may have been impacted, Excellus has created a dedicated website  and a toll-free number to call for more details. That number is 877-589-3331.
