| Code | Display | Definition | 
| resource | Resource | The context is all elements matching a particular resource element path. | 
| datatype | Datatype | The context is all nodes matching a particular data type element path (root or repeating element) or all elements referencing a particular primitive data type (expressed as the datatype name). | 
| extension | Extension | The context is a particular extension from a particular profile, a uri that identifies the extension definition. |

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