### Mappings for HL7 v2 Mapping (http://hl7.org/v2)

CdmhEncounter
Encounter |
identifier | PV1-19
use | N/A
type | CX.5
system | CX.4 / EI-2-4
value | CX.1 / EI.1
period | CX.7 + CX.8
assigner | CX.4 / (CX.4,CX.9,CX.10)
status | No clear equivalent in HL7 v2; active/finished could be inferred from PV1-44, PV1-45, PV2-24; inactive could be inferred from PV2-16
class | PV1-2
type | PV1-4 / PV1-18
serviceType | PV1-10
priority | PV2-25
subject | PID-3
episodeOfCare | PV1-54, PV1-53

end | DR.2
length | (PV1-45 less PV1-44) iff ( (PV1-44 not empty) and (PV1-45 not empty) ); units in minutes
reasonCode | EVN-4 / PV2-3 (note: PV2-3 is nominally constrained to inpatient admissions; HL7 v2 makes no vocabulary suggestions for PV2-3; would not expect PV2 segment or PV2-3 to be in use in all implementations )
reasonReference | EVN-4 / PV2-3 (note: PV2-3 is nominally constrained to inpatient admissions; HL7 v2 makes no vocabulary suggestions for PV2-3; would not expect PV2 segment or PV2-3 to be in use in all implementations )
diagnosis |
condition | Resources that would commonly referenced at Encounter.indication would be Condition and/or Procedure. These most closely align with DG1/PRB and PR1 respectively.
