Problem: Insurance company needs Rendering Provider to populate Loop 2310B or Box 24J on HCFA.
Solution: Rendering provider info is only generated when there is a group doing the billing.Lists/Submitters/Submitter Detail and enter the Group Name at the bottom of the window. This will populate Loop 2310B with the appropriate NPI. To verify, open RF file and search 2310B loop and you should see the doctor's name.
