The US Core Condition Encounter Diagnosis Profile inherits from the FHIR [Condition](https://hl7.org/fhir/R4/condition.html) resource; refer to it for scope and usage definitions. US Core version 5.0.0 split the US Core Condition Profile into this profile and the US Core Condition Problems and Health Concerns Profile. This profile meets the requirements of the U.S. Core Data for Interoperability (USCDI) **Encounter Diagnosis** Data Element. It sets minimum expectations for the Condition resource to record, search, and fetch information about an encounter diagnosis. It specifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption. 

**Example Usage Scenarios:**

The following are example usage scenarios for this profile:

* Query for a Patient's current or historical encounter diagnosis
* [Record or update](us-core-roadmap.md#future-candidate-requirements-under-consideration) a Patient's encounter diagnosis

### Mandatory and Must Support Data Elements

The following data elements must always be present ([Mandatory](must-support.md) definition) or must be supported if the data is present in the sending system ([Must Support](must-support.md) definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The [Formal Views](#profile) below provides the formal summary, definitions, and terminology requirements.

**Each Condition Must Have:**

1. a category code of 'encounter-diagnosis'
1. a code that identifies the condition*
1. a patient

**Each Condition Must Support:**

1. an encounter
1. date record was first recorded

**Additional USCDI Requirements:**

These [Additional USCDI Requirements](must-support.md#additional-uscdi-requirements) elements are not Mandatory or Must Support but are required for ASTP Health IT certification testing and are included in the formal definition of the profile and the Condition examples.

1. a recorder*

**Profile Specific Implementation Guidance:**

* For Problems and Health Concerns, use the [US Core Condition Problems and Health Concerns Profile](StructureDefinition-us-core-condition-problems-health-concerns.md).
* *The `Condition.code` has an **additional binding** of "[current](https://hl7.org/fhir/R5/terminologies.html#binding)" and a base "preferred" binding. 
* For the conformance rules on the current binding for coded data, review [this section](general-requirements.md#current-binding-for-coded-elements) in the General Requirements page.
* USCDI's applicable vocabulary standards for Encounter Diagnosis are SNOMED CT and ICD-10-CM. 
* The [US Core Condition Codes](ValueSet-us-core-condition-code.md) only supports ICD-9-CM for historical purposes. When using ICD codes, only **non-header** ICD-10-CM codes **SHOULD** be used as the primary code for current encounter diagnoses.
 
 
* The encounter **SHOULD** always be referenced in `Condition.encounter`.
* To search for an encounter diagnosis, query for Conditions that reference the Encounter of interest and have a category of `encounter-diagnosis`. An example search is shown in the [Quick Start](#search) section below.

* *The profile elements `Condition.asserter and Condition.recorder` communicate the [individual level provenance](basic-provenance.md#individual-level-provenance) author data corresponding to the U.S. Core Data for Interoperability (USCDI) Provenance Author Data Elements.

**Usages:**

* Refer to this Profile: [US Core Encounter Profile](StructureDefinition-us-core-encounter.md)
* Examples for this Profile: [Condition/encounter-diagnosis-example1](Condition-encounter-diagnosis-example1.md) and [Condition/encounter-diagnosis-example2](Condition-encounter-diagnosis-example2.md)
* CapabilityStatements using this Profile: [US Core Client CapabilityStatement](CapabilityStatement-us-core-client.md) and [US Core Server CapabilityStatement](CapabilityStatement-us-core-server.md)

Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile's information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the [US Core Server CapabilityStatement](CapabilityStatement-us-core-server.md) for a complete list of supported RESTful interactions for this IG.

* See the [Scopes Format](scopes.md#scopes-format) section for a description of the SMART scopes syntax.
* See the [Search Syntax](general-guidance.md#search-syntax) section for a description of the US Core search syntax.
* See the [General Requirements](general-requirements.md) section for additional rules and expectations when a Server requires status parameters.
* See the [General Guidance](general-guidance.md) section for additional guidance on searching for multiple patients.
