About HL7 V3

HL7V3, like V2.x, is a standard for exchanging messages among healthcare information
systems.However, HL7 V3 is not compatible with V2. V3 denes a more fully-specied data
modelwith less exibility for customization. This presents a tighter standard that is easier to
use,and provides a higher level of formal modeling, complexity, and internal consistency.
HL7V3 is based on information models, which dene the specications of sets of data that are
specicto one area of interest. There are dierent types of information models, including:
ReferenceInformation Model (RIM) – Denes the information content for a domain.
DomainInformation Model (D-MIM) – Denes a set of class clones, attributes, and
relationships,and is a subset of the RIM. Domains include the following:
Domainsunder Administrative Management:
Accountingand Billing
Claims& Reimbursements
PatientAdministration
PersonnelManagement
Scheduling
Domainsunder Health and Clinical Management:
ClinicalDocument Architecture
MedicalRecords
PublicHealth Reporting
ClinicalGenomics
SpecimenDomain
RegulatedStudies
RenedMessage Information Model (R-MIM) – Denes message-specic content, and is
asubset of the D-MIM).
