Usage

CRD Clients SHALL use this profile to resolve references to VisionPrescription resources passed to CRD Servers (e.g. selections context references) and to populate draftOrders context objects when invoking the when invoking the following CDS Hooks:

• order-select
• order-sign

Information provided in Must Support elements will commonly be required for CRD Servers to perform coverage requirements discovery.

NOTE: This profile is not currently based on US Core because US Core does not yet profile the VisionPrescription resource. If a future version of US-Core adds support for the resource, this profile will be revised to extend the US Core profile.
