Procedure resource (FHIR R4)

Procedure is a FHIR R4 resource. The Pidgeon engine generates synthetic Procedure instances and validates them against the R4 structure definitions.

Example

{
  "resourceType": "Procedure",
  "id": "procedure-633290a318844135e391dee9e9c324bc",
  "status": "completed",
  "code": {
    "coding": [
      {
        "system": "http://www.ama-assn.org/go/cpt",
        "code": "omitted",
        "display": "CPT code omitted from this published example"
      },
      {
        "system": "http://snomed.info/sct",
        "code": "omitted",
        "display": "SNOMED CT code omitted from this published example"
      }
    ],
    "text": "Colonoscopy"
  },
  "subject": {
    "reference": "Patient/patient-L46A6EIB9J"
  },
  "performedDateTime": "2026-04-18T12:00:00Z"
}

Generated by the Pidgeon engine: pidgeon generate Procedure --seed 20260722. Codes from licensed terminologies (LOINC, SNOMED CT, CPT, RxNorm) are omitted from published examples.

Validation context

• strict pidgeon validate grades a Procedure instance against the base R4 structure definition: missing required elements raise REQUIRED_FIELD_MISSING and cardinality violations raise CARDINALITY_MIN or CARDINALITY_MAX.(REQUIRED_FIELD_MISSING)
• strict Profile validation grades the same instance against an installed IG profile: profile cardinality findings carry FHIR-PROFILE-CARDINALITY and terminology binding findings carry FHIR-PROFILE-BINDING.(FHIR-PROFILE-CARDINALITY)
