### Logical Definition (CLD)

- Include these codes as defined in `http://hl7.org/fhir/event-status` version 📦4.0.1

  Code | Display | Definition
  preparation | Preparation | The core event has not started yet, but some staging activities have begun (e.g. surgical suite preparation). Preparation stages may be tracked for billing purposes.
  in-progress | In Progress | The event is currently occurring.
  on-hold | On Hold | The event has been temporarily stopped but is expected to resume in the future.
  stopped | Stopped | The event was terminated prior to the full completion of the intended activity but after at least some of the 'main' activity (beyond preparation) has occurred.
  completed | Completed | The event has now concluded.
  entered-in-error | Entered in Error | This electronic record should never have existed, though it is possible that real-world decisions were based on it. (If real-world activity has occurred, the status should be "stopped" rather than "entered-in-error".).
  unknown | Unknown | The authoring/source system does not know which of the status values currently applies for this event. Note: This concept is not to be used for "other" - one of the listed statuses is presumed to apply, but the authoring/source system does not know which.
