Called my chiropractic office saying they were doing a survey on behalf of Blue Cross and Blue Shield and wanted to talk to my insurance secretary. Fortunately she was not here. It sounded fishy, so I googled it and found this site. I guess it is a scam.
Turns out to be legit. Some company is conducting a survey for Blue Cross/Blue Shield. They should only be calling people who bill that insurance. I had been missing calls from this number and no message was left. So, today when I had the chance, I took the call and participated in the survey just to see if it was legit.
The questions were all about experiences with billing and verification with BC/BS. No fishy questions; no personal data asked for.
