My husband's company changed to GroupHEALTH back in April 2020. Previously, the receptionist was able to put the claims through directly. Not anymore :(. I have to do them myself.
My claims keep getting denied even though I have read through my coverage and I even wrote an appeal email with the guidance of one of their staff over the phone (she was actually good). Since this is not my primary coverage, I now have to take a picture of my denial from my primary coverage and submit that with my claim. No where does it say to do this! This company is banking that people will give up. One of my claims was finally paid out but the other two I submitted at the same time, nothing. Worst ever!

Edited to say that I emailed as per the response below and I got an immediate email saying I was blocked :(. Absolutely awful.
