### The National Directory of Healthcare Providers & Services (NDH) Profiles

The following presents the list of Directory NDH profiles. Each profile defines the minimum mandatory elements, extensions, and terminology requirements that are required to be present [Must Support](conformance.md#must-support)). For every profile, there is a simple summary of requirements and guidance, the usage and scope of the profile, and the boundaries and relationship with other profiles. A structured table presents a [logical view](https://hl7.org/fhir/R4/formats.html#table) of the content in both a differential and snapshot view. This is complemented with references to relevant terminologies, search parameters, and examples.

* [Directory Endpoint](StructureDefinition-ndh-Endpoint.md)
* [Directory Group](StructureDefinition-ndh-Group.md)
* [Directory HealthcareService](StructureDefinition-ndh-HealthcareService.md)
* [Directory InsurancePlan](StructureDefinition-ndh-InsurancePlan.md)
* [Directory Location](StructureDefinition-ndh-Location.md)
* [Directory Network](StructureDefinition-ndh-Network.md)

### The NDH Extensions And Their Relationship With The NDH Directory Profiles

To address the particular use case requirements of the NDH, a set extension is defined. The subsequent table demonstrates where these extensions are incorporated within the profiles.

### NDH Search Parameters

To facilitate efficient data retrieval and standardized querying from the NDH, a series of search parameters has been established. The associated set of search parameters for each profile can be found in the subsequent list.

* [Endpoint Search Parameters](StructureDefinition-ndh-Endpoint.md#search-parameters)
* [Group Search Parameters](StructureDefinition-ndh-Group.md#search-parameters)
* [HealthcareService Search Parameters](StructureDefinition-ndh-HealthcareService.md#search-parameters)
* [InsurancePlan Search Parameters](StructureDefinition-ndh-InsurancePlan.md#search-parameters)
* [Location Search Parameters](StructureDefinition-ndh-Location.md#search-parameters)
* [Network Search Parameters](StructureDefinition-ndh-Network.md#search-parameters)
* [Organization Search Parameters](StructureDefinition-ndh-Organization.md#search-parameters)
* [OrganizationAffiliation Search Parameters](StructureDefinition-ndh-OrganizationAffiliation.md#search-parameters)
* [Practitioner Search Parameters](StructureDefinition-ndh-Practitioner.md#search-parameters)
* [PractitionerRole Search Parameters](StructureDefinition-ndh-PractitionerRole.md#search-parameters)
* [Verification Search Parameters](StructureDefinition-ndh-Verification.md#search-parameters)

### NDH Code Systems

Due to the unavailability of certain required concepts in existing code systems, a distinct set of code systems has been defined within the NDH. You can view this list via the link provided below:

* [NDH Code System](artifacts.md#terminology-code-systems)

### NDH Value Sets

The use cases within NDH require specific values not found in the existing value sets. As such, the NDH has defined a set of value sets, which are listed via the link provided below:
