This Code system is used in the following value sets:

  • ValueSet: ObservationStatus (Codes providing the status of an observation.)
  • ValueSet: ObservationStatus (Codes providing the status of an observation.) ObservationStatus

Codes providing the status of an observation. This code system defines the following codes:

Lvl Code Display Definition
1 registered Registered The existence of the observation is registered, but there is no result yet available.
1 preliminary Preliminary This is an initial or interim observation: data may be incomplete or unverified.
1 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.
1 amended Amended Subsequent to being Final, the observation has been modified subsequent. This includes updates/new information and corrections.
2   corrected Corrected Subsequent to being Final, the observation has been modified to correct an error in the test result.
1 cancelled Cancelled The observation is unavailable because the measurement was not started or not completed (also sometimes called "aborted").
1 entered-in-error Entered in Error The observation has been withdrawn following previous final release.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".).
1 unknown Unknown The authoring/source system does not know which of the status values currently applies for this observation. Note: This concept is not to be used for "other" - one of the listed statuses is presumed to apply, but the authoring/source system does not know which.

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. 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
