Caller type: Survey
I got a voice message from 215-302-4564 asking me to call 1-833-764-0470 about important info they needed. It concerned BCBS of TN and they mentioned my name. I called BCBS of TN direct and they said it was a firm they use to collect survey info. I guess they do it for other companies, too. BCBS asked if I wanted to be on their Do Not Call and Do Not Write list and I said Yes. I forgot the name of the firm, but suggest you call your medical group directly to verify any calls you get - including the number I mentioned (in case that number transfers to someone else in the future).
