I am a Medical Biller, I recently signed up two separate Provider Practice in California. Both for Oral Surgery. I submitted claims to Blue Shield for both providers. Both providers claims got rejected from the clearing house. The clearning house stated I needed to contact blue shield regarding the doctor's NPI and information. I verified information with Blue shield that both NPI and information was correct. Provider was enrolled as a out of network provider. However, my claims still will not clear the clearing house. So I must drop to paper to Blue shield. Any suggestions as to what is the problem.
