NIS Description of Data Elements

 
ASOURCEUB92 - Admission source, (UB-92 standard coding)

General Notes
 

Three HCUP data elements contain information on the source of admission:

  • ASOURCEUB92 (available beginning in 2002 for HCUP data in general, and in 2003 for the NIS) indicates the source of admission and uses the same coding as the source of admission data element on the UB-92 claim form. ASOURCEUB92 has more detailed categories for routine admissions and transfers from other health facilities than the HCUP data element ASOURCE. Some states do not provide enough detail in the coding of the source of admission to accurately code ASOURCEUB92. For these states, the data element ASOURCEUB92 is not available.
  • ASOURCE (available for all data years) indicates the source of the admission (emergency department; transfer from a hospital; routine, birth and other; etc.) recoded into HCUP uniform values. Routine, birth, and other (ASOURCE=5) include referrals from physicians, clinics, and HMOs. Transfer from a hospital may include transfers within the same hospital as well as transfers between hospitals. If the data source does not provide the admission source, then beginning in the 1998 data, ASOURCE is not present on the HCUP files. In the 1988-1997 data, ASOURCE is retained on the HCUP files and is set to unavailable from source (.B).
  • ASOURCE_X (available beginning in 1998 data) retains the source of admission as provided by the data source. The original values have not been recoded into uniform HCUP values and are source-specific. ASOURCE_X is available for all states that provide HCUP with information on admission source.

The Uniform Billing UB-04 Specifications changed Source of Admission to Point of Origin for Admission or Visit. While this change was scheduled to start as of October 1, 2007, the change-over date was not universally followed. To accommodate the new information two data elements were added to the HCUP databases - PointOfOriginUB04, for uniformly coded values, and PointOfOrigin_X, for values as received from source. During HCUP processing of the 2007 calendar year data, coding was examined by hospital and information was stored in ASOURCEUB92/ASOURCE_X and PointOfOriginUB04/PointOfOrigin_X as most appropriate. Sometimes there was not a succinct change from one coding scheme to another. Original source values are retained in ASOURCE_X and PointOfOrigin_X if there are any question about the coding.

Beginning with 2004: Admission source is coded for newborns.
Prior to 2004: The admission source provided by Texas (ASOURCE_X) was blank for all newborn admission types (ATYPE=4) in the source data file. Because the majority of newborn admissions are routine, the HCUP source of admission was assigned to routine (ASOURCE=5), if the admission type was newborn (ATYPE=4). In order to achieve this, the following code was implemented: If ASOURCE_X = ' ' and ATYPE ='4' then ASOURCE = '5' ;
For all other values, ASOURCE is coded from ASOURCEUB92.
