This profile sets minimum expectations for a MedicationRequest resource in the context of a patient summary in an Australian context. It is based on the [AU Core MedicationRequest](http://hl7.org.au/fhir/core/StructureDefinition/au-core-medicationrequest) profile, and applies the additional requirements from [MedicationRequest (IPS)](http://hl7.org/fhir/uv/ips/StructureDefinition/MedicationRequest-uv-ips). 

See [Comparison With Other National and International IGs](comparison.md) for a comparison between AU Patient Summary (AU PS) profiles and profiles in other implementation guides.

### Profile Specific Implementation Guidance

* See the [guidance on implementing the MedicationRequest resource](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-medicationrequest.html#profile-specific-implementation-guidance) in AU Core.
* When populating `MedicationRequest.medicationCodeableConcept` producers **SHALL** correctly populate `MedicationRequest.medicationCodeableConcept.coding` with either a code from [Australian Medication](https://healthterminologies.gov.au/fhir/ValueSet/australian-medication-1) or [PBS Item Codes](https://build.fhir.org/ig/hl7au/au-fhir-base//ValueSet-pbs-item.html), or both, if a coded value is known and **MAY** populate with a code from another code system. 
* Producers **MAY** populate with only text if no coded value is known.
 
* The MedicationRequest resource can represent the clinical indication as a code with `MedicationRequest.reasonCode`, or a reference with `MedicationRequest.reasonReference` to a Condition or other resource. 
* Although both are marked as **Must Support**, producers are not required to support both a code and a reference, but they **SHALL** support **at least one** of these elements
* A consumer **SHALL** support both elements
 
* The MedicationRequest resource **SHALL NOT** be used to represent that a patient is not currently taking any medications; systems **SHOULD** use the MedicationStatement resource following the [profile specific implementation guidance](StructureDefinition-au-ps-medicationstatement.md#profile-specific-implementation-guidance) in [AU PS MedicationStatement](StructureDefinition-au-ps-medicationstatement.md).

**Examples for this Profile**: [Bundle/aups-gpvisit-retrieval](Bundle-aups-gpvisit-retrieval.md)

**Usages:**

* Use this Profile: [AU PS Bundle](StructureDefinition-au-ps-bundle.md)
* Refer to this Profile: [AU PS Composition](StructureDefinition-au-ps-composition.md)

For example, if you require form or lot number, then you must reference the Medication resource.\r\n\r\nTo improve global interoperability, IPS strongly encourages the use of a reference to a Medication resource, and medicationCodeableConcept is only recommended for cases where no other information than a simple code is available.\r\n\r\nAU PS does not adopt the IPS guidance that systems should only populate a Medication reference when more information than a simple code is available; either medicationReference or medicationCodeableConcept can be used. Future releases of AU PS, based on implementation experience in Australia may adopt that IPS guidance."
