• Unique Device Identifier:

  • CHANGE: Used to only apply to implantable medical devices, now broadened to apply to ALL devices used in medical care

  • Specific ask: Feedback on whether Unique Device Identifier (UDI) should be one or two data elements (Unique Device Identifier—Implantable and Unique Device Identifier—Non-implantable). Is there an impact on standards development or information exchange to use one data element, Unique Device Identifier, to include both implantable and non-implantable devices?

  • Notes:

    • previoulsy rejected additional data element for test kit and instrument identifiers can now be covered by this

• Laboratory Order:

  • CHANGE: identifies LOINC as the standard to use - version 2.78

  • Notes:

• Performance Time (under Procedure):

  • CHANGE: Definition is now

  • Notes:

• Result Unit of Measure:

  • CHANGE: Definition is now: Unit of measurement to report quantitative laboratory test results

  • Notes:

    • Was called out as having updated definition, but definition remained unchanged, but UCUM updated from 2.1 to 2.2

• Updated versions of referenced code systems for these elements in the Laboratory Class:

  • Laboratory Class - Tests → LOINC version 2.78

  • Laboratory Class - Values/Results → SNOMED US Edition September 2024

  • Laboratory Class - Specimen Type → SNOMED US Edition September 2024

  • Laboratory Class - Specimen source site → SNOMED US Edition September 2024

  • Laboratory Class - Result Unit of Measure → UCUM 2.2

  • Laboratory Class - Reference Range → UCUM 2.2

  • Laboratory Class - Specimen Condition Acceptability → SNOMED US Edition September 2024
