## CodeSystem: Segment Group (2.4 - 1.0.0) (Experimental)

Official URL: http://terminology.hl7.org/v2plusvocab/CodeSystem/segmentGroup | Version: 1.0.0
Active as of 2026-01-27 | Computable Name: SegmentGroup
Other Identifiers: OID:2.16.840.1.113883.18.241
Copyright/Legal: HL7 Inc., 2026

HL7-defined code system of concepts specifying the optional segment groups which are to be included in the response. This is a repeating field, to accommodate inclusion of multiple segment groups. The default for this field, not present, means that all relevant groups are included. Used in Version 2 messaging in the Response Control Parameter (RCP) segment.

This Code system is referenced in the content logical definition of the following value sets:

- Hl7VSsegmentGroup
