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

ChOrfRequestedEncounter
Encounter
identifier	PV1-19
identifier (VisitNumber)	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
participant	ROL
type	ROL-3 (or maybe PRT-4)

individual	ROL-4
appointment	SCH-1 / SCH-2
period	PV1-44, PV1-45
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.
