Central Distributor SID: Description of Data Elements
This section describes how HCUP data elements are coded, restrictions on their use, their uniform values, and State-specific coding practices.

General Notes
 

The Uniform Billing UB-04 Specifications changed coding specifications for 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. During HCUP processing, 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 is any question about the coding. Regardless of which variables are reported, the best source for identifying admissions through the emergency department (ED) is the HCUP data element HCUP_ED which looks across admission source, point of origin, and ED charges to identify ED admissions.

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

  • ASOURCEUB92 (available beginning in 2002 data) 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.

If the state includes enough detail in the coding of the source of admission to accurately code ASOURCEUB92, then the HCUP data element ASOURCE is coded from ASOURCEUB92 as specified below. Otherwise, ASOURCE is coded from ASOURCE_X and specifications are listed under State Specific Notes.

The first digit of ASOURCE_X describes the site from which the patient originated (e.g., home (1), residential care facility (2), ambulatory surgery (3), skilled nursing/intermediate care (4), acute inpatient hospital care (5), other inpatient hospital care (6), newborn (7), prison/jail (8), other (9).

The second digit of ASOURCE_X describes the license of site from which the patient originated (e.g., this hospital (1), another hospital (2), not a hospital (3).

The third digit describes the route by which the patient was admitted (e.g., this hospital=s emergency room (1), not this hospital=s emergency room (2). Source value 2 includes patients seen in the emergency room of another hospital and patients not seen in any emergency room.


Newborns

In all years, California assigned all records containing a principal diagnosis code of "newborn, born in hospital" (defined as DX1 equal to V3x.0x) to an admission source of newborn, regardless of the admission source reported by the hospital. These discharges are included under the uniform category routine, birth, and other (ASOURCE = 5).


Home Health Service

Prior to 1995, the categories coded under routine, birth, and other (ASOURCE = 5) included an admission source of "Home Health Service."

Beginning in 1995, home health service is not reported by California as a separate category. No documentation is available from the source to indicate whether home health service is reported under another source category.


Court/Law Enforcement

Prior to 1995, the source documentation supplied by California does not indicate which source categories are used for "Court/Law Enforcement" (ASOURCE=4).

Beginning in 1995, the source reported a separate category for admissions from "Prison/Jail." These discharges are included under the uniform category "Court/Law Enforcement" (ASOURCE = 4).


Ambulatory Surgery

Beginning in 1995, the source reports a separate category for admissions from ambulatory surgery. These discharges are included under the uniform category "Other Facility, Including Long Term Care" (ASOURCE = 3).

Prior to 2002, admission source information was provided in two fields; one for newborns and one for all other patients. ASOURCE_X was assigned as follows:

  • If a newborn record (ATYPE=4) then ASOURCE_X = the newborn admission source, Else ASOURCE_X = the admission source for non-newborns.

In 1995-1996, the admission source, "Transfer from a Rural Primary Care Hospital" was erroneously recoded to the HCUP uniform category "Other Facility, Including Long Term Care" (ASOURCE = 3). Beginning in 1997, the admission source "Transfer from a Rural Primary Care Hospital" was correctly recoded to the HCUP uniform category "Another Hospital" (ASOURCE = 2). This source value was not available from New Jersey prior to 1995.

Admitted from Outpatient Department

  • For 1988-1992, the source category "Admitted From Outpatient Department" was recoded to the HCUP uniform category "Routine, Birth and Other" (ASOURCE = 5).
  • For 1993, New York recoded "Admitted From Outpatient Department" into the source category "Emergency Room" and during HCUP processing, it was assigned to the HCUP category "Emergency Department" (ASOURCE = 1).
  • Beginning in 1994, New York does not report "Admitted from Outpatient Department."

Transfer from a Rural Primary Care Hospital

  • Beginning in 1995, New York reported the admission source, "Transfer from a Rural Primary Care Hospital." This was recoded to the HCUP uniform category "Another Hospital" (ASOURCE = 2).
