This code system http://hl7.org/fhir/resource-status defines the following codes:

CodeDefinition
error The resource was created in error, and should not be treated as valid (note: in many cases, for various data integrity related reasons, the information cannot be removed from the record)
proposed The resource describes an action or plan that is proposed, and not yet approved by the participants
planned The resource describes a course of action that is planned and agreed/approved, but at the time of recording was still future
draft The information in the resource is still being prepared and edited
requested A fulfiller has been asked to perform this action, but it has not yet occurred
received The fulfiller has received the request, but not yet agreed to carry out the action
declined The fulfiller chose not to perform the action
accepted The fulfiller has decided to perform the action, and plans are in train to do this in the future
arrived The pre-conditions for the action are all fulfilled, and it is imminent
active The resource describes information that is currently valid or a process that is presently occuring
suspended The process described/requested in this resource has been halted for some reason
failed The process described/requested in the resource could not be completed, and no further action is planned
replaced The information in this resource has been replaced by information in another resource
complete The process described/requested in the resource has been completed, and no further action is planned
inactive The resource describes information that is no longer valid or a process that is stopped occurring
abandoned The process described/requested in the resource did not complete - usually due to some workflow error, and no further action is planned
unknown Authoring system does not know the status
unconfirmed The information in this resource is not yet approved
confirmed The information in this resource is approved
resolved The issue identified by this resource is no longer of concern
refuted This information has been ruled out by testing and evaluation
differential Potentially true?
partial This information is still being assembled
busy-unavailable not available at this time/location
free Free for scheduling
on-target Ready to act
ahead-of-target Ahead of the planned timelines
behind-target Behind the planned timelines
not-ready Not ready to act
transduc-discon The device transducer is disconnected
hw-discon The hardware is disconnected
