This code system http://hl7.org/fhir/medication-admin-status defines the following codes:
| Code | Display | Definition |
| in-progress | In Progress | The administration has started but has not yet completed. |
| on-hold | On Hold | Actions implied by the administration have been temporarily halted, but are expected to continue later. May also be called "suspended". |
| completed | Completed | All actions that are implied by the administration have occurred. |
| entered-in-error | Entered in Error | The administration was entered in error and therefore nullified. |
| stopped | Stopped | Actions implied by the administration have been permanently halted, before all of them occurred. |
| unknown | Unknown | The authoring system does not know which of the status values currently applies for this request. Note: This concept is not to be used for "other" - one of the listed statuses is presumed to apply, it's just not known which one. |
