# NDH Value Sets - National Directory of Healthcare Providers & Services (NDH) Implementation Guide v2.0.0-current

## NDH Value Sets

NDH uses standardized value sets where possible. Often the value set needs to be specific to use-cases. As such, the NDH has defined a set of value sets:

[Accepting Patients Codes Value Set](ValueSet-AcceptingPatientsVS.md)

This value set defines NDH concepts used to represent whether a practice, service, or role is accepting new patients.

[Accessibility Value Set](ValueSet-AccessibilityVS.md)

This value set defines NDH accessibility accommodation categories used to describe available access-support options across directory records.

[Age Range Value Set](ValueSet-AgeGroupVS.md)

This value set defines NDH age-group concepts used to represent age-based eligibility or targeting criteria in directory data.

[Benefit Type Value Set](ValueSet-BenefitTypeVS.md)

This value set defines insurance benefit-type concepts used to classify covered services and benefit categories for plan comparison and eligibility interpretation.

[Employment Status Value Set](ValueSet-EmploymentStatusVS.md)

This value set defines employment-status concepts used by NDH to represent an individual's current employment situation in a standardized form.

[Endpoint Access Control Mechanism Value Set](ValueSet-EndpointAccessControlMechanismVS.md)

This value set defines endpoint access-control mechanism concepts used to declare authentication and authorization approaches for secure exchange.

[Endpoint Connection Types Value Set](ValueSet-EndpointConnectionTypeVS.md)

This value set defines endpoint connection-type concepts for NDH endpoints by combining core, IHE, and NDH supplemental connection semantics.

[Endpoint FHIR Mimetype Value Set](ValueSet-EndpointFhirMimeTypeVS.md)

This value set defines permitted FHIR MIME-type representations used to declare supported FHIR serialization formats for endpoint exchange.

[Endpoint IHE Specific Connection Types Value Set](ValueSet-EndpointIheSpecificConnectionTypeVS.md)

This value set defines IHE-specific endpoint connection-type concepts used when exchange needs are more specific than general connection-type codes.

[Endpoint Payload Type Value Set](ValueSet-EndpointPayloadTypeVS.md)

This value set defines NDH endpoint payload-type constraints and, in this guide, intentionally limits payload typing to the not-applicable designation.

[Endpoint Testing Method Value Set](ValueSet-EndpointTestingMethodVS.md)

This value set defines endpoint testing-method concepts used to represent how endpoint validation, conformance, or certification evidence was established.

[FaCeT Practitioner Credential Properties Value Set](ValueSet-FaCeTcredentialVS.md)

This value set defines FaCeT practitioner credential concepts used to represent standardized practitioner credentials and related qualification terms in NDH content.

[FaCeT Organizational Credential Properties Value Set](ValueSet-FaCeTorganizationCredentialVS.md)

This value set defines FaCeT organizational credential concepts used to represent standardized accreditation, certification, and related organizational credential terms in NDH content.

[Individual Qualifications Value Set](ValueSet-HealthcareIndividualTaxonomyVS.md)

This value set defines individual healthcare qualification concepts from the NUCC Provider Taxonomy, including specialties, degrees, licenses, and certifications relevant to individual practitioners. It intentionally excludes grouping-level and non-individual organization categories (for example agencies, facilities, hospitals, laboratories, managed care organizations, suppliers, and transportation services) to keep the expansion aligned to individual practitioner use.

[Healthcare Service Eligibility Code Value Set](ValueSet-HealthcareServiceEligibilityCodeVS.md)

This value set defines healthcare-service eligibility concepts, drawing from condition and procedure value sets to represent qualification criteria for service access.

[HealthcareService Type Value Set](ValueSet-HealthcareServiceTypeVS.md)

This value set defines detailed healthcare-service type concepts used to classify specific clinical, social, and support services in NDH directory exchange.

[Identifier Status Value Set](ValueSet-IdentifierStatusVS.md)

This value set defines identifier-status concepts used to communicate lifecycle state and operational validity of identifiers in directory records.

[Individual Specialties, Degrees, Licenses, and Certificates Value Set](ValueSet-IndividualSpecialtyAndDegreeLicenseCertificateVS.md)

This value set defines individual specialty, degree, license, and certificate concepts by combining specialty and healthcare taxonomy sources for richer credential representation.

[Individual Specialty Value Set](ValueSet-IndividualSpecialtyVS.md)

This value set defines individual specialty concepts used to represent practitioner specialty designations in a consistent coded format.

[Insurance Status Value Set](ValueSet-InsuranceStatusVS.md)

This value set defines insurance-status concepts used by NDH to communicate whether coverage is insured, uninsured, or underinsured.

[NDH Care Team Category Value Set](ValueSet-NDHCareTeamCategoryVS.md)

This value set defines NDH care-team category concepts used to classify the primary coordination focus of a care team in directory exchange.

[Associated Servers Type Value Set](ValueSet-NdhAssociatedServersTypeVS.md)

This value set defines associated-server type concepts used to classify companion or supporting server roles linked to NDH endpoints.

[NDH Endpoint Environment Value Set](ValueSet-NdhEndpointEnvironmentVS.md)

This value set defines NDH endpoint environment concepts used to distinguish production and non-production endpoint deployment contexts.

[Healthcare Service Category Value Set](ValueSet-NdhHealthcareServiceCategoryVS.md)

This value set defines broad healthcare-service category concepts used to classify the general type of services being provided or offered.

[NDH endpoint Implementation Guide Value Set](ValueSet-NdhImplementationGuideVS.md)

This value set defines implementation-guide use-case concepts used to indicate which interoperability guides and exchange scenarios an endpoint supports.

[Secure Exchange Artifacts Value Set](ValueSet-NdhSecureExchangeArtifactsVS.md)

This value set defines secure-exchange artifact type concepts used to categorize certificates and related trust artifacts for endpoint interoperability.

[NDH Verification Status Value Set](ValueSet-NdhVerificationStatusVS.md)

This value set defines NDH verification-status concepts used to communicate whether verification is complete, incomplete, or not required.

[Network Type Value Set](ValueSet-NetworkTypeVS.md)

This value set defines the network-type designation used to classify NDH network entities distinctly from general organization categories.

[Organization Alias Type Value Sete](ValueSet-OrgAliasTypeVS.md)

This value set defines organization-alias type categories used to distinguish how alternate organization names are used in directory contexts.

[Organization Type Value Set](ValueSet-OrgTypeVS.md)

This value set defines organization-type categories used to classify directory organizations by role and function while excluding network-only typing.

[OrganizationAffiliation Roles](ValueSet-OrganizationAffiliationRoleVS.md)

This value set defines organization-affiliation role concepts, combining HL7 and HIE-oriented role sources to classify affiliation relationships consistently.

[PractitionerRole Code Value Set](ValueSet-PractitionerRoleVS.md)
