Blue Cross and Blue Shield of Oklahoma Data Breach: Full Details

On April 13, 2025, Blue Cross and Blue Shield of Oklahoma (BCBSOK) disclosed a data breach to the U.S. Department of Health and Human Services, affecting 1,020 individuals in the United States. The breach involved unauthorized access to the Blue Access for Members™ (BAM™) online portal, which is used by members to view their health insurance information. According to BCBSOK, suspicious activity was detected on February 11, 2025, revealing that protected health information (PHI) and personally identifiable information (PII) may have been viewed by an unauthorized individual. The incident potentially occurred over a four-month period, from November 8, 2024, to March 5, 2025.

The types of information exposed in this breach included name, address, date of birth, service dates, telephone numbers, fax numbers, email addresses, medical record numbers, health plan beneficiary numbers, account numbers, and medical/dental service and billing information. This data spans both PII and PHI, increasing the risk for those affected, as it could potentially be used for identity theft or insurance fraud.

The breach was reported to federal regulators and details are available on the U.S. Department of Health and Human Services breach portal. BCBSOK also posted a detailed notice for affected members on its website.
