General Notes

DXPOAn indicates whether each diagnosis (DXn) was present at admission. This provides an indicator of complications arising during a hospitalization. The coding of this data element is consistent with the UB-04 standards. No edits checks are performed on this data element during HCUP processing. Beginning with the 2017 HCUP databases, external cause of morbidity codes are included with other diagnoses in the diagnosis-related data elements (I10_DXn, I10_NDX, and DXPOAn) and are no longer retained in separate data elements (I10_ECAUSEn, I10_NECAUSE, and E_POAn). From 1998 to 2006, this data element was called DXatAdmitn and coded with 0/1 values. Before 1998, this data element is called TMDXn.
