OCR description
On November 15, 2016, a business associate (BA), Summit Reinsurance, notified the covered entity (CE), PrimeWest Health, of a data security incident involving the CE’s data. The breach affected approximately 2,441 individuals. The protected health information included patients’ names, addresses, date of birth, and social security numbers. The BA mitigated the breach by taking the computer server offline and by confirming that the ransomware was limited to a specific server. The BA also assessed and removed any remote access to the data through the ransomware. The CE provided breach notification to the media, affected patients and HHS. OCR obtained documented assurances that the CE implemented the corrective actions listed above.
