| use | N/A |
| type | CE/CNE/CWE |

| 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 | CE/CNE/CWE subset one of the sets of component 1-3 or 4-6 |

| reasonCode | CE/CNE/CWE |
| 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. |
