MedicationAdministration-Nullification MedicationAdministration-Nullification Someone wishes to record that the record of administration of a medication is in error and should be ignored. MedicationAdministration-Recording MedicationAdministration-Recording Indicates that a medication has been recorded against the patient's record. MedicationAdministration-Update MedicationAdministration-Update Update a Medication Administration record. admin-notify admin-notify Notification of a change to an administrative resource (either create or update).

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies See Code System for further information.
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding ). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
