Some WellPoint Inc customers got a surprise in their inbox this week: emails meant to remind them to get a specific preventative screening such as a colonoscopy or mammogram mistakenly included personal and health information in the subject line. WellPoint declined to say how many customers received the emails or the cause of the technology issue. An Anthem BlueCross customer in California sent the email she received to Reuters. Subject: "[PROOF] - Don’t miss out - call your doctor today; PlanState: CA; Segment: SMALL GROUP; Age: Female Young; Language: EN; CervCancer3yr: N; CervCancer5yr: N; Mammogram: N; Colonoscopy: N"
