State Specific Notes
General Notes
 

Beginning with the 2017 HCUP databases, International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) 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).

Prior to 2017, E_POAn is used to indicate whether each external cause of injury code (I10_ECAUSEn for the fourth quarter of 2015 and all of 2016; ECODEn prior to the fourth quarter of 2015) 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.

State Specific Notes

Arizona

For 2011, the data source has informed us that some hospitals had problems reporting Present on Admission indicators. We recommend checking hospital statistics before using this data element.

In 2010 only, the DXPOAn data elements have been suppressed for one hospital that provided erroneous data for the indicators that the diagnosis was present on admission on most of its discharges.
