At least 16 client companies and more than 23 million patients are estimated to have been affected by the incident. The data breach was discovered on March 21 by AMCA, which appears to be the largest health data breach of the year so far this year. As of July 25, only one victim entity – Natera – had a breach report for the AMCA incident posted on the Department of Health and Human Services HIPAA Breach Reporting Tool website.”]
