Concepts

This case-sensitive code system http://terminology.hl7.org/v2plusvocab/CodeSystem/sequenceResultsFlag defines the following codes:

CodeDisplayDefinitionversion introducedcomment, to suppress IG-publisher warning, to be replaced with standard latermodified
C Cyclical Cyclical 2.5 Used for indicating a repeating cycle of service requests; for example, individual intravenous solutions used in a cyclical sequence (a.k.a. "Alternating IVs"). This value would be compatible with linking separate service requests or with having all cyclical service request components in a single service request. Likewise, the value would be compatible with either Parent-Child messages or a single service request message to communicate the service requests' sequencing 2015-07-13
