Claim Attending Physician NPI Number (FFS)

SAS Name
AT_PHYSN_NPI

On an institutional claim, the national provider identifier (NPI) number assigned to uniquely identify the physician who has overall responsibility for the beneficiary's care and treatment.

NPIs replaced UPINs as the standard provider identifiers beginning in 2007. The UPIN is almost never populated after 2009.
