I am not able to get my out of state BCBS claims to properly route to the BCBS of OK. I have changed all payor IDs for the out of state policies (for example, BCBS of Texas) to be that of BCBS of OK electronic payor ID but they are still being rejected. The rejections is "Rendering NPI is not on file". I have verified all NPI numbers correct. I have had no luck getting response/help from BCBS or our Clearinghouse. I can't be the only one who has had this problem... Help!!
