MedicationStatement

Work with FHIR R4 4.0.1 MedicationStatement resources.

Choose an operation for this resource:

The diagram summarizes MedicationStatement requests and responses. See Supported FHIR REST Interactions for the shared interaction model.


A FHIR client sends requests to the DDFS R4 MedicationStatement API. Search returns a Bundle; create, read and update return a resource; vread returns one historical version; delete returns HTTP 204 without a body. Custom operations and FHIR-formatted errors can return OperationOutcome.

FHIR R4 definition: https://hl7.org/fhir/R4/medicationstatement.html. See interaction response codes and common error responses.
