Hi LB,
Thank you for your question.
Yes, this is expected behavior for both CCLF and BCDA data. These values are placeholders that get inserted when the real rendering provider TIN or NPI is not available at the time the claim is created. The values you shared for CLM_RNDRG_PRVDR_TAX_NUM and RNDRG_PRVDR_NPI_NUM reflect that the actual provider values were not included.
Thanks,
The BCDA Team
