# CRD Communication Request - Da Vinci - Coverage Requirements Discovery v2.2.1

## Resource Profile: CRD Communication Request 

 
This profile specifies constraints on the CommunicationRequest resource to support coverage requirements discovery. 

### Usage

§§prof-3^crd-client^exchange:CRD Clients **SHALL** use the CRD CommunicationRequest profile to [resolve references](foundation.md#additional-data-retrieval) to CommunicationRequest resources passed to CRD Servers (e.g. `selections` context references) and to populate `draftOrders` context objects.^

CRD Clients **SHALL** use the CRD CommunicationRequest profile to [resolve references](foundation.md#additional-data-retrieval) to CommunicationRequest resources passed to CRD Servers (e.g. `selections` context references) and to populate `draftOrders` context objects when invoking the following CDS Hooks:

* [order-select](hooks.md#order-select)
* [order-sign](hooks.md#order-sign)
* [order-dispatch](hooks.md#order-dispatch)

§§

Information provided in [Must Support](http://hl7.org/fhir/R4/profiling.html#mustsupport) elements will commonly be required for CRD Servers to perform coverage requirements discovery. 

**Usages:**

* Use this Profile: [CRD CDSHooks Additional Orders Response (Logical Definition)](StructureDefinition-CRDHooksResponse-additionalOrders.md), [CRD CDSHooks Alternate Request Response (Logical Definition)](StructureDefinition-CRDHooksResponse-alternateRequest.md), [CRD CDSHooks Coverage Information Response (Logical Definition)](StructureDefinition-CRDHooksResponse-coverageInformation.md) and [CRD Bundle of Request Resources](StructureDefinition-profile-bundle-request.md)
* Refer to this Profile: [Coverage Information](StructureDefinition-ext-coverage-information.md) and [CRD Communication Request](StructureDefinition-profile-communicationrequest.md)
* CapabilityStatements using this Profile: [CRD Client USCDI 1](CapabilityStatement-crd-client3.1.md), [CRD Client USCDI 3](CapabilityStatement-crd-client6.1.md) and [CRD Client USCDI 4](CapabilityStatement-crd-client7.0.md)
