I got a call today from pharmacists "working with my insurance company", they wanted to review my medications.  After asking me to verify my name they proceeded to ask my birthdate.  At this point I said you are wanting to give me information, not te other way around.  They hurried me off the phone, saying they would mail me something.
Looks fishy (phishy) to me.

These folks call my wife's job! this is bull crap.

I got a 412 call from caller saying they're Anthem asking for birthdate and want to verify who I am.  I hung up, called back and got the same computer asking for the same info.  I hung up.  I had a question on my healthplan, called the number on my card and asked them were they calling me yesterday and they said no. So It's BOGUS!  Also, they have no office in Pennsylvania that I know of.

The phone number 855-222-8921. the caller id was 412-773-8572. It appears to be a mobile phone. Maybe the information was stolen.

Same phone call - one to me - one for my wife.   Caller ID does NOT equal "Anthem" or anything that would exist IF this were a legit call.  

Likely robo-callling in geographies over and over and over.   The caller ID and the calling number will likely change over time - - - the content of their recording will be the same until everyone figures it out.

Blue Cross Blue Shield robo call saying "Are you more stressed in the new year? If so, here are some numbers you can call... blah blah blah."  Nothing major.

very suspicious...of course I called the number on the back of my insurance card & couldn't get a real person. so i guess there is no way to contact anthem blue cross via phone to report this suspicious voice mail left by the robot at this number.

Have received messages from this phone number a few times now also stating they are from Anthem. I will not be calling them back after seeing all of this.

Received the same message yesterday.
I was very unhappy, wandoring why would a insurance company calling to remind me to get health checks since I JUSTH had my annual last month.
And if their is a health issue, why my Dr. did call and a insurnace company would call me.
Good thing I found this post before calling the 855xxxxxxxx back.

Exact same situation happened to me with exactly the same numbers.  Thanks to all of you -- I WILL NOT be calling them back.

posing as Anthem/Blue Cross - without authority...
Recommend only calling Anthem # listed on your ID card

I received a call from this number, which my husband answered.  It was all robot, and rather than give information, my husband got the callback number and told me about it.  I googled it and got to this page, and after reading it, opted instead to call Anthem Blue Cross directly rather than use the callback number.  Anthem confirmed that they did not try to call me and do not have toll-free numbers that start with 855.  They also said that their usual policy is to try to call their members again, rather than have their members call them back.

Arg. It seems they have called Kaiser members and Blue Shield members too. I haven't found a single post from anyone indicating that they have reached a human and that the call is legitimate. I have found postings where it seems like the caller ID number might be spoofed, because some posters said they hit call back rather than the number specified in the message. The person who answered the phone had no idea what they were talking about, and they had been receiving a bunch of similar calls from members of that same health insurance company (at that time, it was Aetna). I'm pretty convinced now that this is a scam.

Yup I got it today too. They left a message (robot voice). They identified themselves as calling from Anthem Blue Cross, said they had "an important health reminder" for me (stated my name) and asked them to call me back at 855-874-7379 (said it was toll-free). My caller ID said the call came from "Pittsburgh PA" and the number was 412-723-5999. When you Google the Pittsburgh number, there's more info posted about the call. Supposedly it's for some "women's health check" message. But they want you to confirm a lot of personal info first (all asked by robot not human) and they give an 877 number "to opt out of future messages". If you look at some of the reports from other time periods, it appears this number has called Aetna members too (back in Oct 2010). At BEST this is a marketing company. At WORST it is a phishing scam (likely since they are asking people to confirm personal information like birthdates). Either way, the call didn't originate from an Anthem Blue Cross telephone number. Beware.

I just got the same call. I said yes to my phone number, since they had that already, hung up when they wanted my birthday. If the message is that urgent, send me a letter or email, this type of notification is just asking for mimics using it for phishing.

turns out it is legit, but why take my word for it, right?   ;-)
It's robo-advice for your health.  
I'd say:  always call the number on your card when calling back!  but you knew that.

I got an exact call today. Sounds fishy to me. I never have health issues.

This was from Anthem/Blue Cross with some kind of message regarding your health.  When it asked me to input my date of birth, I hung up because it seemed fishy they were asking me input information.  Although a mechanical voice said my name and asked me to verify by saying yes or no if I was that person.  May have been legit but didn't want to take a chance with phishers.
