# CRD Encounter - Da Vinci - Coverage Requirements Discovery v2.2.1

## Resource Profile: CRD Encounter 

 
This profile specifies additional extensions and constraints on the US Core Encounter profile to support coverage requirements discovery. 

### Usage

§§prof-7^crd-client^exchange:CRD Clients **SHALL** use the CRD Encounter profile to [resolve references](foundation.md#additional-data-retrieval) to Encounter resources passed to CRD Servers, including `encounterId` context references.^

CRD Clients **SHALL** use the CRD Encounter profile to [resolve references](foundation.md#additional-data-retrieval) to Encounter resources passed to CRD Servers, including `encounterId` context references when invoking the following CDS Hooks:

* [appointment-book](hooks.md#appointment-book)
* [encounter-start](hooks.md#encounter-start)
* [encounter-discharge](hooks.md#encounter-discharge)
* [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 Coverage Information Response (Logical Definition)](StructureDefinition-CRDHooksResponse-coverageInformation.md) and [CRD Bundle of Request Resources](StructureDefinition-profile-bundle-request.md)
