description: This Task profile is used to solicit information from a system. The Data Consumer uses it when direct query transactions are not an option, and the transaction may require human intervention. It represents both the data request and the returned \"data request\". Data requests are supplied as codes, free-text, or FHIR Restful queries. It can also support requests for more detailed missing data using Questionnaire, CQL, and QuestionnaireResponse as supported by Da Vinci DTR.\n\nIt constrains the following elements to be *mandatory* (min=1):\n\n- A Task.status with a required binding to HRex [Task Status ValueSet](http://hl7.org/fhir/us/davinci-hrex/STU1/ValueSet-hrex-task-status.html) (this element is a mandatory Task element). For guidance when the provider is not able to complete the Task, refer to the [When The Task Cannot Be Completed section](http://hl7.org/fhir/us/davinci-cdex/STU2/task-based-approach.html#when-the-task-cannot-be-completed).\n- A Task.intent fixed to \"order\" (this element is a mandatory Task element)\n- A Task.code of either \"data-request-code\", \"data-request-code\", or \"data-request-questionnaire\" communicating that the Data Consumer is requesting data using a code(or free text), a FHIR RESTful query, or a data request questionnaire.\n - If the code is \"data-request-query\", the provider system returns data(s) identified by the FHIR RESTful query in the \"query\" input parameter.\n - If the code is \"data-request-code\", the provider system returns data(s) identified by the LOINC code in the \"code\" input parameter.\n - If the code is \"data-request-questionnaire\", the provider system uses [Documentation Templates and Rules (DTR)](http://hl7.org/fhir/us/davinci-dtr/2022May/) to complete the Questionnaire referenced in the \"questionnaire\" input parameter.\n- A Task.for element representing the member (i.e.,patient) for whom the data is being requested\n- A Task.requester element communicating who is requesting the data\n- A Task.owner element representing the Provider who is being asked to provide the data\n\nIt constrains following elements to be [*must support*](task-based-conformance.html#cdex-must-support-definition) (min=0):\n\n- A Task.identifier element representing the unique data request identifier\n- A Task.basedOn element to communicate the order (ServiceRequest, CommunicationRequest, etc.) that authorizes the data request\n- A Task.statusReason.text to communicate the reason for the status (for example, if the Task is rejected or failed)\n- A Task.businessStatus.text element representing the progress in retrieving the data (for example, \"waiting on internal review\").\n- A Task.for.reference.identifier element representing a patient business identifier like a Member ID\n- A Task.requester.reference.identifier element representing the Data Consumer business identifier\n- A Task.owner.reference.identifier element representing the Provider business identifier\n- A Task.reasonCode.text to communicate why the data is being requested\n- A Task.reasonReference.reference.identifier for the claim, pre-auth or coverage business identifier\n- A \"query\" Task.input element to communicate to the provider what information is needed using a FHIR RESTful query.*\n- A \"code\" Task.input element to communicate to the provider what information is needed using a LOINC code.*\n - For the \"code\" Task.input element, an extensible LOINC® Document types value set to communicate the specific information being requested\n- A Task.input element representing a flag to indicate whether the requested data requires a signature\n - A \"data\" Task.output element referring to FHIR resource(s) representing the result(s) of the data request code.\n\nIt defines the following elements to be *optional*:\n- A meta.tag element representing work-queue hints.\n- A \"questionnaire\" Task.input element to communicate to the provider a URL of a data request [FHIR Questionnaire](http://hl7.org/fhir/questionnaire.html) that conforms to the [DTR SDC Questionnaire Profile](http://hl7.org/fhir/us/davinci-dtr/StructureDefinition/dtr-sdc-questionnaire) or the [DTR SDC Questionnaire for Adaptive Form Profile](http://hl7.org/fhir/us/davinci-dtr/StructureDefinition/dtr-sdc-questionnaire-adapt).*\n - A questionnaireDisplay extension to communicate the display name of the Questionnaire\n- A Task.input element representing the purpose of use for the requested data using an extensible [CDex Purpose of Use Value Set](http://hl7.org/fhir/us/davinci-cdex/ValueSet/cdex-POU)\n- A \"response\" Task.output element which is a local reference to the [FHIR QuestionnaireResponse](http://hl7.org/fhir/questionnaireresponse.html) resulting from the data request Questionnaire. The QuestionnaireResponse conforms to the [SDC Questionnaire Response Profile](http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaireresponse) or the [SDC Adaptive Questionnaire Response Profile](http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaireresponse-adapt).\n\nIt prohibits the following elements (max=0):\n- Task.focus\n\n\\* Either a \"query\", \"code\", or \"questionnaire\" Task.input element is required package_name: hl7.fhir.us.davinci derivation: constraint name: CDexTaskDataRequest type: Task elements: meta: index: 0 elements: tag: index: 1 elements: system: {index: 2} code: {index: 3} required: [code] slicing: rules: open discriminator: -
