Read the PDex Plan-Net CapabilityStatement (v1.2.0) to confirm which search parameters are supported; the server must support at least the mandatory search parameters for each resource type as defined in the IG
Query Practitioner: GET /Practitioner?name=<name>&_include=Practitioner:qualification to retrieve practitioners and their qualifications; use Plan-Net Practitioner profile constraints for credential and identifier elements
Query PractitionerRole with chained parameters to find practitioners by network or service type: GET /PractitionerRole?network=<Network-id>&_include=PractitionerRole:practitioner&_include=PractitionerRole:location
Query Organization: GET /Organization?type=<org-type>&_include=Organization:endpoint to retrieve health system organizations and their FHIR endpoint references; Organization type codes come from the Plan-Net organization type value set
Query HealthcareService: GET /HealthcareService?organization=<Org-id>&specialty=<NUCC-code> to find services offered at a specific organization with a specific specialty; specialty uses NUCC Health Care Provider Taxonomy codes
Use InsurancePlan queries to find plan-network relationships: GET /InsurancePlan?type=<plan-type>&_include=InsurancePlan:administered-by to retrieve plans and their administering organizations
Known gotchas
Plan-Net uses PractitionerRole and OrganizationAffiliation (not direct Practitioner-to-Organization links) to model participation in a network — querying Practitioner alone will not reveal network membership
Plan-Net profiles derive from US Core Practitioner and Organization profiles (STU4) but add Plan-Net-specific extensions (e.g., qualification, communication); servers that serve US Core resources without Plan-Net extensions will not be conformant
The Plan-Net IG is currently v1.2.0 (FHIR R4); avoid confusing it with the broader PDex (Payer Data Exchange) IG — Plan-Net covers provider directories only, not member clinical or claims data exchange
