State of TN, Bureau of TennCare

The covered entity (CE) mailed the wrong information to 3,900 individuals based on a corrupted data file it received from a state agency. The types of PHI involved were names, dates of birth, social security numbers, member identification numbers, and in some cases, diagnoses, treatments, conditions, and medications. Following the breach, the CE immediately fixed the corrupted file and mailed corrected letters. The CE provided breach notification to HHS, the media, and affected individuals and provided substitute notification by posting on its website. It also offered affected individuals one year of free credit monitoring and comprehensive credit services. The CE also worked with the state agency to implement a new procedure to improve safeguards for PHI. OCR obtained assurances that the CE implemented the corrective action listed above. \ \
