  title: drChrono Patient Registration (Upsert)
  summary: Search for an existing patient by name and update it if found, otherwise create a new patient record.
  description: >-
    A patient demographic upsert against the drChrono EHR REST API, aligning with
    USCDI patient demographic data elements. The patient is searched by name; when
    a match is found the existing patient record is updated, and when no match is
    found a new patient is created. This is the standard deduplicating intake step
    at the front of most clinical and revenue cycle integrations. Every step inlines
    its request so the flow is self-contained.
