The data breach may have exposed data on an estimated 1,656,569 patients of CaptureRx's provider customers, according to a report that the company submitted to HHS' Office for Civil Rights on May 5. The HHS agency publicly posted the report to its online database of healthcare data breaches in an update this week. CaptureRx in February discovered files containing patient names, dates of birth and prescription data had been accessed and acquired by an unauthorized user earlier in the month.
