My provider is looking into becoming credentialled with a local hospital. As for now, he is just going to be doing psychological testing there. They want us to do his billing. Once he is affiliated with the hospital, what do I do? I know that I would need to contact all insurance companies that we are networked with, but would we have contract with all insurances that the hospital takes? I have never worked for a hospital or facility, therefore, I have know idea about UB04 claim forms. Please help. I dont have time to do my job now much less do something like this. I WOULD APPRECIATE ANY GUIDANCE.
