GET [baseUrl]/MedicationOrder?patient=[id]&code=[code]
See token for details on this parameter. ‘code’ can be used multiple times as a search parameter
system
is a uniform resource identifier which defines which CodeSystem the code belongs to. This is optional and if not present all matching codes will be returned regardles of CodeSystems.

See reference for details on this parameter. The patient parameter can be used two ways:
This SHALL be supported for all endpoint provider systems.
id
is the logical id of the patient on the server which can be obtained by a Patient resource query.
GET [baseUrl]/MedicationOrder?patient=42
Return all MedicationOrder resources for Patients with a logical id of 42
This SHOULD be supported by middleware systems (e.g. enterprise application integration (EAI) and the enterprise service bus (ESB)) and MAY be supported for endpoint provider systems.
system
is a uniform resource identifier which defines which CodeSystem the identifer belongs to. For NHS Number this would be https://fhir.nhs.uk/Id/nhs-number
and code
would be the NHS Number.
GET [baseUrl]/MedicationOrder?patient.identifier=https://fhir.nhs.uk/Id/nhs-number|9876543210

2.1.4. status
See token for details on this parameter.
To filter on status ( active | on-hold | completed | entered-in-error | stopped | draft
)
GET [baseUrl]/MedicationOrder?patient=1&status=active
Return all MedicationOrder resources with a status of active and Patient with a logical id of 1.
2.2. Search Response
If the search fails (cannot be executed, not that there is no matches), the return value is a status code 4xx or 5xx with an OperationOutcome.
If the search succeeds, the return content is a Bundle with type = searchset containing the results of the search as a list of resources in a defined order. The result list can be long, so servers MAY use paging. If they do, they SHALL use this Paging method for breaking the list into pages if appropriate. The server MAY also return an OperationOutcome resource with additional information about the search; if one is sent it SHALL NOT include any errors, and it shall be marked with an entry mode of include.
A full set of response codes can be found here API Response Codes. FHIR Servers SHALL support the following response codes:
200 | successful operation |
404 | resource not found |
410 | resource deleted |
