This tutorial explains the governance and processes which support vocabulary and its use in HL7 standards. The appropriate use of vocabulary in health software and information exchange is important for safe, effective and unambiguous information exchange. This tutorial identifies how to correctly implement code system content into HL7 messages and content as well as how to facilitate the development of code system content in HL7 standards. This tutorial covers requirements for HL7 Version 2 and Version 3, CDA® and FHIR®.

• Those involved in the implementation or development of HL7 standards, or health information systems, including:

• Those implementing vocabulary content in IT systems based upon HL7 standards
• Those participating in the Vocabulary Work Group
• HL7 vocabulary facilitators

Upon Completion of This Tutorial, Students Will Know:

• What a code system is in health information exchange and why it is important
• The HL7 processes for terminology content
• The structures for vocabulary in HL7 Version 2.x
• How coded data is represented in Version 3 messages
• How to use value sets and concept domains as they apply in HL7
• The use of OIDs in HL7 vocabulary maintenance
