UHC is not communicating with the regional provider about policy coverage from a claim with service date March 28, 2020. WellMed only shows the policy was in effect on May 1, 2020. Every UHC rep in the phone has told me to do something different every time. The provider has submitted a claim, but they get a denial - policy was not in effect till May 21, 2020. I have emailed, called, faxed, and mailed USPS the same set of forms 3 times! Now again, I have been told the to do the same process for the 3rd time. The people answering the 800 phone lines DO NOT KNOW WHAT TO DO! I have had the Medicare AARP policy since 2015. Very disappointed. Facing suit by the provider.
