100% looks like a typical fraud phishing letter but is also is noted as being on behalf of Blue Cross and Blue Shield. However, right out the gate it is sent with "extreme urgency" and threatening methods of sending multiply times with a count down if you don’t reply "immediately". Which makes no sense as letter following a standard very typical everyday type doctor visit.I decided to succumb to the threatening letter to call but with a plan to not give out any vital personal info if they should ask. Sure enough, when you call the number they immediately want personal information (name/birth date/etc) from you. I just let them know that if they have access to the doctor visit and/or Blue Shield they should have all that information about the visit and there is nothing else I would add nor would I be giving out any of my personal information. He then says okay that he doesn’t have anything else to ask me. Which makes the whole call and the "extreme urgent" letters seem like phishing scam to attempt to pull personal info verbally from me. I don’t believe this company has a legit purpose for anything on behalf of Blue Shield Blue Cross.
