Notice of Cognizant / TMG Data Incident

Sept. 5, 2023

Recently, Blue Cross and Blue Shield of Texas (BCBSTX) mailed letters to members with past or current health insurance coverage with BCBSTX. These letters were to inform you about a recent incident involving your Protected Health Information (PHI) as required under the law.

What Happened: On 06/23/2023 we became aware that your PHI was accessed by an unauthorized party on 06/21/2023 at a vendor of TMG Health (TMG). TMG provides third party administrative services to Medicare enrollees of HCSC Insurance Services Company (HISC). HISC is contracted with the Centers for Medicare and Medicaid Services (CMS) to offer this product.

What Information Was Involved: The information that was disclosed included your name, address, email address, phone number, date of birth, Social Security Number, Claim number, bank account number and medical service information. We have investigated the incident and determined that due to the unauthorized access by a bad actor, your information may have been disclosed to the wrong individual.

What We Are Doing: In order to minimize any harm, TMG is working closely with the vendor to ensure systems are updated to block these activities and prevent disclosures of this nature from occurring in the future. TMG is committed to maintaining the privacy and security of your information and is taking this incident very seriously. Our vendor has notified law enforcement to mitigate this situation as best as possible.
