# Profiles

This IG uses the `Medication` resource to represent the items within a formulary and the `Composition` resource to depict the structure of formularies for a health insurer.

_TODO: These profiles are using http://example.org/fhir as their baseurl, which is not real. Find an authoritative location to store these profiles._

## FormularyList
The `FormularyList` profile is based on `Composition` and allows for the insurer and formulary metadata to be properly conveyed in a single resource.  Since insurers are expected to maintain several formularies at any given time, each `section` represents a single formulary and each `section.entry` is a medication within that formulary.

## FormularyMedication
The `FormularyMedication` profile is based on the `Medication` resource and does a few things:
* Adds formulary metadata elements as extensions
* Similar to US Core, it sets the code system as RxNorm
    * _TODO: actually base this resource on US Core instead_
* It requires a text value to be associated with each medication
    * _TODO: is this appropriate?_
