Hi Lori,
Not sure why the credentialing manager has the out of network provider using their social security number. How is the practice setup: sole proprietor, LLC, or Corporation? This will determine if the providers can be sued personally. Depending on the insurance, it usually doesn't make a difference if the provider is in-network or out of network in regards to if the social or Tax ID being used. We do credentialing and most, if not all, of our providers use a Tax ID number to submit claims under whether they or in or out of network.
