April 13, 2026: Delivery type now captured from free-text documentation

We’ve added support for identifying delivery type when it appears in free-text clinical documentation and creating a standardized FHIR Procedure resource from it. Supported mappings currently include Cesarean delivery (SNOMED CT 11466000) and Vaginal delivery of fetus (SNOMED CT 700000006).

You can identify Procedure resources derived from narrative text by a meta.tag indicating they come from unstructured content and by code.coding.userSelected set to false.

Below is an example of what the relevant portions of the FHIR resource will look like:

{
  "resourceType": "Procedure",
  "status": "completed",
  "code": {
    "coding": [
      {
        "system": "http://snomed.info/sct",
        "code": "11466000",
        "display": "Cesarean delivery",
        "userSelected": false
      }
    ],
    "text": "Cesarean delivery"
  },
  "meta": {
    "tag": [
      {
        "system": "https://zusapi.com/fhir/StructureDefinition/data/enrichment",
        "code": "unstructured-source"
      }
    ]
  }
}

This applies to all documents ingested on or after April 6, 2026.
