[US Core MedicationDispense](https://hl7.org/fhir/us/core/STU9/StructureDefinition-us-core-medicationdispense.html)

# Stable ID

The `id` is derived from the patient, last filled date, sold date, product code, drug description, directions,
strength, and days supply. If a subsequent request contains a record with all of the same values, it resolves to
the same `MedicationDispense`.
