Resource Profile: CRD Vision Prescription

Official URL: http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-visionprescription Version: 2.2.0-ballot
Standards status: Trial-use Active as of 2025-10-30 Maturity Level: 1 Computable Name: CRDVisionPrescription
Other Identifiers: OID:2.16.840.1.113883.4.642.40.18.42.19

This profile defines an initial profile on the VisionPrescription resource to support coverage requirements discovery.

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:

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.
