877-352-4381

Nice try.  This number is not published on their website.  The only form of contact is a web form.  Further a search of this number comes up with almost no hits, but one Google result does show it as a Medical Alert scam number.  There would have been no reason for you to look up the number after they called if you were truly convinced that this was that company calling you about your billing information.  I have reported your post as "misinformation".

Called and wanted to verify my new Medicare #-said they were with a lab associated my dr. uses. BEWARE!

This number is billing for LabCorp. I use it all the time with my patients.

If you already know to whom this number belongs, why did you look it up?

They have called me and I didn't answer. I don't owe any money to them. When I called back to speak to someone, the lady said they would be calling me back. Makes no sense.

A lady from this number 877-352-4381 called me, said she called from lab Corp, billing department, asked me confirm date of birth, and insurance information . I feel not safe, hang up and researching... it’s scam

Lady left message that she’s from labcorp and needs to update informations to call back. No thanks, send me a letter.

I received a call from +1 (877) 352-4381, a guy left a message stating they needed to update my insurance information, he left my name, dob, and reference number. I called the number back, although suspicious to me, the person who took my call asked for the reference #, the guy repeated the # twice on the voicemail so it was hard to figure it out, so the lady asked for the first 3 letters of my first and last name and my dob. She found me, said they needed the insurance name and claims address. I asked what it was for and she said a lab that was done on July 3rd. I said oh I bet that is from a COVID test and she confirmed it was from a CVS for a COVID test. It sounded weird but it was legit and she was super nice. After the call and speaking with them I knew it wasn't a scam. Hope this helps!

It also happened to me an hour ago. And I called them back. Even though I had my doubts too. It was about my covid test needed my insurance number and Medicare ID number for part B. That made me wonder! But I gave her the information.

just received a hard to understand vmail from them as well.  i wonder why they need more info since i already provided it at the time the appointment was made?  kinda sketchy...

" i wonder why they need more info since i already provided it at the time the appointment was made?" Possibly because this wasn't a legitimate call?

I don’t want to give my Medicare # to this co. That drugstore has billed Medicare for ex before so there’s no reason that labcorp should be receiving a # with a digit missing.  They can send a letter if they’re legit.
