On June 12, 2019, a business associate (BA), United WestLabs, Inc., notified the covered entity (CE), that its subcontractor, American Medical Collection Agency, experienced a security incident between August 1, 2018 and March 30, 2019, when an unauthorized user gained access to the subcontractor’s computer server. The incident affected individuals across several different CEs including West Hills Hospital & Medical Center. The types of electronic protected health information (ePHI) involved in the incident included names, addresses, medical account numbers, dates of services, amounts paid, referring doctors’ codes, and disposition codes. The CE provided breach notification to HHS, affected individuals, and the media. Following the breach, the CE ceased sending collection accounts to the subcontractor. OCR obtained documentation of the applicable BA agreements and obtained assurances that the CE implemented the corrective action steps listed above.
