This case-sensitive code system http://terminology.hl7.org/CodeSystem/task-code defines the following codes:

CodeDisplayDefinition
approve Activate/approve the focal resource Take what actions are needed to transition the focus resource from 'draft' to 'active' or 'in-progress', as appropriate for the resource type. This may involve additing additional content, approval, validation, etc.
fulfill Fulfill the focal request Act to perform the actions described in the focus request. This might result in a 'more assertive' request (order for a plan or proposal, filler order for a placer order), but is intend to eventually result in events. The degree of fulfillment requested might be limited by Task.restriction.
instantiate Instantiate the focal definition Act to perform the actions defined in the focus definition resource (ActivityDefinition, PlanDefinition, Questionnaire, etc.) For PlanDefinition or ActivityDefinition, this might result in a 'more assertive' request (order for a plan or proposal, filler order for a placer order), but is intend to eventually result in events. For Questionnaire, this would result in a QuestionnaireResponse - and possibly resources constructed using data extracted from the response. The degree of fulfillment requested might be limited by Task.restriction.
abort Mark the focal resource as no longer active Abort, cancel or withdraw the focal resource, as appropriate for the type of resource.
replace Replace the focal resource with the input resource Replace the focal resource with the specified input resource
change Change the focal resource Update the focal resource of the owning system to reflect the content specified as the Task.focus
suspend Suspend the focal resource Transition the focal resource from 'active' or 'in-progress' to 'suspended'
resume Re-activate the focal resource Transition the focal resource from 'suspended' to 'active' or 'in-progress' as appropriate for the resource type.
data-request Data request task A type of Task asking the Task.owner to deliver the data corresponding to the characteristics defined by the Task.inputs to the Task.requester
