This profile constrains AU Core Medicationto meet the requirements of this Implementation Guide for medications. Implementers are highly encouraged to review AU Core Medication profile before using this profile. The purpose of this profile is to provide a representation of a medication for the electronic exchange of health information between individuals, healthcare providers, and the My Health Record system infrastructure in Australia.

This profile defines medication representation requirements for a Clinical Note Document in Australia, ensuring consistent capture of medication details including brand and generic names for accurate and interoperable exchange of medication information across healthcare settings.

Usages:

- Use this Profile: CND Bundle
- Refer to this Profile: CND MedicationStatement
- Examples for this Profile: Medication/ex-medication-crestor
