identifier	PV1-19
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

userSelected	Sometimes implied by being first

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 )

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.
