Encounter for care delivered in the community/HMO setting or for hospital ambulatory visits that do not involve admission. The encounter is typically self-contained. It MAY be linked to other encounters via EpisodeOfCare to represent a series of visits for chronic care (e.g., dialysis) or other relationships (e.g., a nurse ECG performed following a physician visit in the same HMO appointment). It SHALL NOT use partOf to link to other encounters. Duration is expected to be short (minutes to hours); the exact start or end time MAY be unknown and not recorded, but at least one SHALL be present. Visits to HMO-operated/community emergency centers MAY be modeled with this profile, however, if more structured representation is required using ILHDPEncounterHospitalization/ILHDPEncounterInpatientCareSegment might be more appropriate.
