Rules for Review and Assignment of V2.x Tables

HL7 V2 Tables and HL7 V3 Concept Domains

The name of every HL7 V2.x table will represent the name of a HL7 V3 Concept Domain. HL7 V3 Concept Domains will be created with names as similar as possible to their corresponding Version 2 artifacts. (9-June-2011 Minutes)

HL7 V2.x "User" tables with No Suggested Values will be represented as a Concept Domain only (no code systems or value sets). (9-June-2011 Minutes)

HL7 V2 Tables and HL7 V3 Value Sets

HL7 V2.x Tables that have associated values are HL7 V3 Value Set. (9-June-2011 Minutes)

The Value Sets defined as "all codes" from the code systems built from the V2 standard tables will be Type 21 OIDs. (9-June-2011 Minutes, 22-August-2013)

HL7 V2 Tables and HL7 V3 Code Systems

HL7 V2.x Tables that have associated values that are HL7 authored and published in an HL7 V2 Standard are HL7 V3 Code System. (9-June-2011 Minutes)

HL7 V3 code systems that are created from the enumerated values of V2 code tables will be registered as Type 18 OIDs. (9-June-2011 Minutes)

New Code Systems

Any change to the domain (semantic boundary) of a Code System will result in a new Code System. (9-June-2011 Minutes)

HL7 V2 Tables and HL7 V3 Bindings

HL7 V2.x "HL7" Tables have a UV (Universal) binding between the Concept Domain and the Value Set. (9-June-2011 Minutes)

HL7 V2.x "HL7" Table bindings have a coding strength of Coded With Exceptions (CWE), with the following exceptions (9-June-2011 Minutes):

  • exception 1
  • exception 2

HL7 V2.x "User" Tables have either a Representative realm (R1) or an Example realm (X1) binding between the Concept Domain and the Value Set. The binding decisions are arbitrary based upon the perception and consensus agreement by the review group of the completeness of domain coverage by the published set of codes. (9-June-2011 Minutes)

HL7 V2.x "User" Table bindings have a coding strength of Coded With Exceptions (CWE), with the following exceptions (9-June-2011 Minutes):

  • exception 1
  • exception 2
