| Official URL: https://haau3.com/fhir/StructureDefinition/haau3-medication-statement | Version: 1.0.0 | |||
| Draft as of 2026-10-14 | Computable Name: Haau3MedicationStatement | |||
A medication a care recipient is or was taking, as the source system recorded it. Delivered exactly as it arrived: assertion dates are never sent by current sources, effective dates rarely, and dosage is predominantly the source's own free text. Read together with haau3 MedicationRequests when assembling a medication list.
