## Resource Profile: AU PS Medication

This profile sets minimum expectations for a Medication resource in the context of a patient summary in an Australian context. It is based on the AU Core Medication profile, and applies the additional requirements from Medication (IPS).

See Comparison With Other National and International IGs 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 Medication resource in AU Core.
- When populating `Medication.code` producers SHALL correctly populate `Medication.code.coding` with either a code from Australian Medication or PBS Item Codes, 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 Medication 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 in AU PS MedicationStatement.

Examples for this Profile: Bundle/aups-gpvisit-retrieval, Bundle/aups-referral-endoconsult-autogen and Bundle/aups-referral-endoconsult-curated

Usages:

- Use this Profile: AU PS Bundle
- Refer to this Profile: AU PS MedicationRequest and AU PS MedicationStatement

You can also check for usages in the FHIR IG Statistics
