I have a provider who billed BCBS/NH code H0031 with a GAD diagnosis. The claim denied because the code is not on the providers fee schedule. BCBS is advising me that if I can resubmit with the H0031 but a different non-covered diagnosis code then it would deny as a non-covered and the provider can collect from patient. I am really at a loss I have never billed the H0031 code and just need any help I can get with this.
