In health care messaging and healthcare generally it is vitally important that the correct test, procedure, report etc is done on the right patient and the results are consigned to the appropriate person.  The use of identifiers plays a major role in ensuring clinical safety in messaging and the healthcare system.

The representation of healthcare identifiers used for patient, provider organisation and health identifiers in HL7 V2.x messages uses the common attributes of HL7 Table 0203 - Identifier Type and User-defined Table 0363 - Assigning Authority below.


HL7 Table 0203 - Identifier Type 

ValueDescriptionComment
ACSNAccession IDAccession Identifier
AMAmerican ExpressDeprecated and replaced by BC in v 2.5.
AMA

American Medical Association
Number

A physician identifier assigned by the AMA.
ANAccount numberAn identifier that is unique to an account.
ANONAnonymous identifier

An identifier for a living subject whose real identity is protected or suppressed
Justification: For public health reporting purposes, anonymous identifiers are occasionally used for protecting patient identity in reporting certain results. For instance, a state health department may choose to use a scheme for generating an anonymous identifier for reporting a patient that has had a positive human immunodeficiency virus antibody test. Anonymous identifiers can be used in PID 3 by replacing the medical record number or other nonanonymous identifier. The assigning authority for an anonymous identifier would be the state/local health department.

Administration registration
number

An identifier for an individual or organization relative to controlled substance regulation and transactions.
Use case: This is a registration number that identifies an individual or organization relative to controlled substance regulation and transactions.
A DEA number has a very precise and widely accepted meaning within the United States. Surprisingly, the US Drug Enforcement Administration does not solely assign DEA numbers in the United States. Hospitals have the authority to issue DEA numbers to their medical residents. These DEA numbers are based upon the hospital’s DEA number, but the authority rests with the hospital on the assignment to the residents. Thus, DEA as an Identifier Type is necessary in addition to DEA as an Assigning Authority.

For this case, the CX data type requires distinct identifier types to accurately interpret component 1. Additionally, the distinction among these license types is critical in most health care settings (this is not to convey full licensing information, which requires a segment to support all related attributes).

  1. In table 0203 - Identifiers it does not reference the veterans codes

    • DVW = DVA Card - White - ADDED per Australian Standard AS4700.1 - 2005
    • DVG = DVA Card - Gold - ADDED per Australian Standard AS4700.1 - 2005
    • DVO = DVA Card - Orange - ADDED per Australian Standard AS4700.1 – 2005
    • DV = Veterans number - ADDED per Australian Standard AS4700.1 – 2005


    However these codes are then used in Table 6.1 Examples


    And

    Do we really need the offshore identifiers in this table, It appears to be an international example, rather than an Australian example.
    i.e.

    • DEA = Drug Enforcement Administration registration number (US)
    • TN = Treaty Number (Canada)
    • NII = National Insurance Organization Identifier (Germany)
    • XX = Organization identifier ??? – A filler or null value I think
