CalOptima Data Breach (2015)

On October 7, 2015, an internal printing error resulted in approximately 100 CalOptima Medi- Cal members with diabetes receiving a health incentive survey that may have included an extra survey meant for another member. We became aware of the error on October 8, 2015, and immediately stopped all printing. However, we were not able to retrieve the surveys that had already been processed for mailing.
