This Code System is normative - it is generated based on the information defined in this specification. The definition will remain fixed across versions, but the actual contents will change from version to version

This Code system is used in the following value sets:



This code system http://hl7.org/fhir/fhir-types defines the following codes:

4      MedicationAdministration MedicationAdministrationDescribes the event of a patient consuming or otherwise being administered a medication. This may be as simple as swallowing a tablet or it may be a long running infusion. Related resources tie this event to the authorizing prescription, and the specific encounter between patient and health care practitioner.resourcebtn btn
4      MedicationDispense MedicationDispenseIndicates that a medication product is to be or has been dispensed for a named person/patient. This includes a description of the medication product (supply) provided and the instructions for administering the medication. The medication dispense is the result of a pharmacy system responding to a medication order.resourcebtn btn
4      MedicationKnowledge MedicationKnowledgeInformation about a medication that is used to support knowledge.resourcebtn btn
4      MedicationRequest MedicationRequestAn order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationRequest" rather than "MedicationPrescription" or "MedicationOrder" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.resourcebtn btn
4      MedicationUsage MedicationUsageA record of a medication that is being consumed by a patient. A MedicationUsage may indicate that the patient may be taking the medication now or has taken the medication in the past or will be taking the medication in the future. The source of this information can be the patient, significant other (such as a family member or spouse), or a clinician. A common scenario where this information is captured is during the history taking process during a patient visit or stay. The medication information may come from sources such as the patient's memory, from a prescription bottle, or from a list of medications the patient, clinician or other party maintains. The primary difference between a medicationusage and a medicationadministration is that the medication administration has complete administration information and is based on actual administration information from the person who administered the medication. A medicationusage is often, if not always, less specific. There is no required date/time when the medication was administered, in fact we only know that a source has reported the patient is taking this medication, where details such as time, quantity, or rate or even medication product may be incomplete or missing or less precise. As stated earlier, the Medication Usage information may come from the patient's memory, from a prescription bottle or from a list of medications the patient, clinician or other party maintains. Medication administration is more formal and is not missing detailed information.resourcebtn btn
