Aetna notified all possibly affected individuals of the breach, filed a breach report with OCR, commenced an investigation to identify and correct the root cause of the issue; the coding changes that were causing the breach were removed from IPS via Aetna's emergency Change Management procedures to prevent any further exposure while the problem was analyzed; once the specific code that conflicted with its proxy server settings was identified as the root cause of the breach, it was removed. Also, in an effort to mitigate any harm as a result of the breach, Aetna offered all affected individuals one year of free credit monitoring, and the notification letters included a toll-free number which was established specifically to answer questions related to this incident. \
