## Resource Profile: CRD Medication Request

Official URL: http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-medicationrequest | Version: 2.2.1 | Highlight text changes?
Standards status: Trial-use Active as of 2026-03-26 | Maturity Level: 4 | Computable Name: CRDMedicationRequest
Other Identifiers: OID:2.16.840.1.113883.4.642.40.18.42.12

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

### Usage

CRD Clients SHALL use the CRD MedicationRequest 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 following CDS Hooks: §prof-9

- order-select
- order-sign
- order-dispatch

!

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

Usages:

- Use this Profile: CRD CDSHooks Additional Orders Response (Logical Definition), CRD CDSHooks Alternate Request Response (Logical Definition), CRD CDSHooks Coverage Information Response (Logical Definition) and CRD Bundle of Request Resources
- Refer to this Profile: Coverage Information, CRD Appointment with Order, CRD Medication Request and CRD Service Request
- CapabilityStatements using this Profile: CRD Client USCDI 1, CRD Client USCDI 3 and CRD Client USCDI 4

You can also check for usages in the FHIR IG Statistics

### 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). §prof-14 This may be necessary for the payer to appropriately respond to coverage information regarding medications associated with medical and DME benefits.
