Da Vinci - Coverage Requirements Discovery
2.0.1 - STU 2 United States of America flag

This page is part of the Da Vinci Coverage Requirements Discovery (CRD) FHIR IG (v2.0.1: STU 2.0) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions

Resource Profile: CRD Medication Request

Official URL: http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-medicationrequest Version: 2.0.1
Standards status: Trial-use Maturity Level: 2 Computable Name: MedicationRequest

This profile specifies additional constraints on the US Core MedicationRequest profile to support coverage requirements discovery.

Usage


CRD Clients SHALL use this profile to resolve references to MedicationRequest 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 accidentally constrained out PractitionerRole. When a future version of US-Core adds support back in, this profile will be revised to extend the US Core profile

Notes

While the codes for the medication are expected to be drawn from RxNorm, EHRs MAY send additional coding repetions to communicate other code systems (e.g. HCPCS J codes). This may be necessary for the payer to appropriately respond to coverage information regarding medications associated with medical and DME benefits.
