This profile identifies the additional constraints, extensions, and value sets that build on and extend Medication that are supported.

A Medication resource is used within the context of a referencing resource: MedicationAdministration, MedicationDispense, MedicationRequest, or MedicationStatement resource.

This profile is designed to set a core Medication standard in the context of:

• Querying medications referenced by another resource
• Recording or updating a medication referenced by another resource
• Reading medications referenced by another resource

Operations on Medication resources are expected to be within the context of an ExplanationOfBenefit, Flag, MedicationAdministration, MedicationDispense, MedicationRequest or MedicationStatement resource query.

Profile specific guidance

• See the Medicine information section for guidance on constructing a resource and the use of medicines terminology.
• Manufacturer information will commonly be exchanged as a PBS code, this information can be represented as an external resource by using Medication.manufacturer.identifier to carry the PBS code and Medication.manufacturer.display to carry the name of the manufacturer.
