### Logical Definition (CLD)

- Include these codes as defined in `http://hl7.org/fhir/observation-status` version 📦4.0.1

  Code | Display | Definition
  final | Final | The observation is complete and there are no further actions needed. Additional information such "released", "signed", etc would be represented using [Provenance](provenance.html) which provides not only the act but also the actors and dates and other related data. These act states would be associated with an observation status of `preliminary` until they are all completed and then a status of `final` would be applied.
  entered-in-error | Entered in Error | The observation has been withdrawn following previous final release. This electronic record should never have existed, though it is possible that real-world decisions were based on it. (If real-world activity has occurred, the status should be "cancelled" rather than "entered-in-error".).

### Expansion

Expansion performed internally based on codesystem ObservationStatus v4.0.1 (CodeSystem)

This value set contains 2 concepts

System | Code | Display (en) | Definition | JSON | XML
`http://hl7.org/fhir/observation-status` | final | Final | The observation is complete and there are no further actions needed. Additional information such "released", "signed", etc would be represented using Provenance which provides not only the act but also the actors and dates and other related data. These act states would be associated with an observation status of `preliminary` until they are all completed and then a status of `final` would be applied. |  |
`http://hl7.org/fhir/observation-status` | entered-in-error | Entered in Error | The observation has been withdrawn following previous final release.

(If real-world activity has occurred, the status should be "cancelled" rather than "entered-in-error".). |  |

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
System | 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
