  title: Particle Health Network Provider Discovery
  summary: Register a patient, run a network query, then discover which providers and organizations hold records for that patient.
  description: >-
    A care-team and provider-directory discovery flow aligned with the HL7 Da
    Vinci Payer Data Exchange (PDex) Plan-Net / provider-directory intent. The
    patient is registered and a network query is launched and polled to
    completion; once records have been gathered, the provider map is read to see
    which organizations responded, and the geographic network participants for the
    patient's state are listed. Each step inlines its request so the flow is
    self-contained.
