| Code | Display | Definition | 
| CodeSystem-expand | CodeSystem-expand | The definition of a code system is used to create a simple collection of codes suitable for use for data entry or validation. An expanded code system will be returned, or an error message. | 
| MedicationAdministration-Complete | MedicationAdministration-Complete | Change the status of a Medication Administration to show that it is complete. | 
| 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). Note that there is no delete, though some administrative resources have status or period elements for this use. |

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 | 
| 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) | 
| 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 | 
| Comments | Additional notes about how to use the code |
