All codes in this table are from the system http://hl7.org/fhir/trigger-type
| Level | Code | Display | Definition | 
| 1 | named-event | Named Event | The trigger occurs in response to a specific named event, and no other information about the trigger is specified. Named events are completely pre-coordinated, and the formal semantics of the trigger are not provided. | 
| 1 | periodic | Periodic | The trigger occurs at a specific time or periodically as described by a timing or schedule. A periodic event cannot have any data elements, but may have a name assigned as a shorthand for the event. | 
| 1 | data-changed | Data Changed | The trigger occurs whenever data of a particular type is changed in any way, either added, modified, or removed. | 
| 2 | data-added | Data Added | The trigger occurs whenever data of a particular type is added. | 
| 2 | data-modified | Data Updated | The trigger occurs whenever data of a particular type is modified. | 
| 2 | data-removed | Data Removed | The trigger occurs whenever data of a particular type is removed. | 
| 1 | data-accessed | Data Accessed | The trigger occurs whenever data of a particular type is accessed. | 
| 1 | data-access-ended | Data Access Ended | The trigger occurs whenever access to data of a particular type is completed. |

Explanation of the columns that may appear on this page:
| Lvl | A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - 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 |
