Generated Narrative: CodeSystem medication-classification-type

This case-sensitive code system http://hl7.org/fhir/medication-classification-type defines the following codes:

CodeDisplayDefinition
anatomical Anatomical ClassClassification by anatomical main group or body system on which the medication acts (e.g., cardiovascular system, alimentary tract). Codes may be drawn from any suitable coding system, such as the anatomical levels of WHO ATC.
therapeutic Therapeutic ClassClassification based on the therapeutic use of the medication (e.g., antihypertensive, analgesic).
pharmacologic Pharmacologic ClassClassification based on the pharmacologic action of the medication (e.g., beta-blocker, ACE inhibitor).
moa Mechanism of ActionClassification based on the mechanism by which the medication exerts its effect.
chemical Chemical Structure ClassClassification based on the chemical structure of the medication (e.g., benzodiazepine, statin).
regulatory Regulatory ClassificationClassification assigned by a regulatory authority (e.g., prescription-only, orphan drug designation, biosimilar status).
controlled-substance Controlled Substance ScheduleClassification under a controlled-substance scheduling scheme (e.g., DEA schedules, narcotic/psychotropic classification).
legal-status Legal/Marketing StatusClassification by legal or marketing status (e.g., prescription-only, over-the-counter, behind-the-counter).
reimbursement Reimbursement/Formulary ClassClassification used for reimbursement or formulary management (e.g., tier, formulary group).
essential-medicines Essential Medicines ListInclusion on a public-health essential-medicines list (e.g., the WHO Model List of Essential Medicines).
