This case, along with two companion cases , involved data lost due to damage and/or opening of priority mail during processing and transit through the United States Post Office. In this case, potentially 15,000 individuals may have been affected. The types of protected health information (PHI) involved in the breach included names, social security numbers, group names, and group numbers. The data was not recovered. The covered entity (CE), Delta Dental, provided breach notification to HHS, affected individuals, and the media. It also took immediate and appropriate steps to mitigate potential damages to individuals and to reduce the likelihood of recurrence. From December 2013 to case closure in September 2015, no further incidents occurred, and OCR determined that the CE’s corrective actions were effective.
