Official notice

Due to a vendor error, the covered entity (CE), Aflac, erroneously sent correspondence containing protected health information (PHI) to the wrong customers, affecting 930 policyholders. The types of PHI included names, policy numbers, types of coverage, employee numbers, and premium amounts, depending on the type of correspondence mailed. In addition, six policyholders’ social security numbers were potentially comprised. In response to the breach, the CE retrained employees and revised its impermissible disclosures and safeguard policies. Additionally, the CE sanctioned the manager who led the address standardization project and terminated its contract with all third party vendors and contractors involved in the breach. The CE provided breach notification to HHS, and affected individuals. Media notice was not required because the incident did not involve more than 500 residents in any particular state. OCR obtained assurances that the CE implemented the corrective actions listed above.
