Hello - If a biller needs detailed information on claims that did not pay, and the insurance companies (beloved) automated phone system does not allow one to speak with a live human being about it, how does one get this information? I submitted several claims to BCBS of Texas, most have paid, but several did not. All the EOB said was "A contract co insurance has been taken" That sounds fine, except BCBS of Texas is the only insurance this patient has, and my provider/client wants to know what to do about this....NOW, and I don't know what to tell him. Any ideas?
