Generated Narrative: CodeSystem medication-classification-type

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

Code	Display	Definition
anatomical	Anatomical Class	Classification 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 Class	Classification based on the therapeutic use of the medication (e.g., antihypertensive, analgesic).
pharmacologic	Pharmacologic Class	Classification based on the pharmacologic action of the medication (e.g., beta-blocker, ACE inhibitor).
moa	Mechanism of Action	Classification based on the mechanism by which the medication exerts its effect.
chemical	Chemical Structure Class	Classification based on the chemical structure of the medication (e.g., benzodiazepine, statin).
regulatory	Regulatory Classification	Classification assigned by a regulatory authority (e.g., prescription-only, orphan drug designation, biosimilar status).
controlled-substance	Controlled Substance Schedule	Classification under a controlled-substance scheduling scheme (e.g., DEA schedules, narcotic/psychotropic classification).
legal-status	Legal/Marketing Status	Classification by legal or marketing status (e.g., prescription-only, over-the-counter, behind-the-counter).
reimbursement	Reimbursement/Formulary Class	Classification used for reimbursement or formulary management (e.g., tier, formulary group).
essential-medicines	Essential Medicines List	Inclusion on a public-health essential-medicines list (e.g., the WHO Model List of Essential Medicines).
