My provider is credentialed at a facility in NJ our billing address is in NY. The payer is BCBS FEP, we're trying to bill the claim to NJ since services were rendered there, but they keep rejecting it saying we have to bill in NY, but the NY plan rejects it. The payer is saying our TIN has to have a billing address in NJ. I've never had this issue before and one of the claims actually paid.
