# US Quality Core MedicationRequest - 2026 US Quality Core Implementation Guide v0.5.0

## Resource Profile: US Quality Core MedicationRequest 

 
Profile of MedicationRequest for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors. 

### USCDI+ Quality Element Support Expectations

Systems are expected to support this profile as part of implementing USCDI+ Quality V1 in FHIR and meeting the conformance requirements of this guide.

The following elements are specifically relevant to USCDI+ Quality V1 data classes and elements. Systems are expected to support these elements as applicable to their role in US Quality Core data exchange. See the [Must Support](must-support.md) section of this guide for more information. These elements are tagged as (USCDI+ Quality) in the formal profile views.

**USCDI+ Quality Elements:**

* status: (USCDI+ Quality) (USCDI) active | on-hold | cancelled | completed | entered-in-error | stopped | draft | unknown
* intent: (USCDI+ Quality) (USCDI) proposal | plan | order | original-order | reflex-order | filler-order | instance-order | option
* medication[x]: (USCDI+ Quality) (USCDI) Medication to be taken
* authoredOn: (USCDI+ Quality) (USCDI) When request was initially authored
* reasonCode: (USCDI+ Quality) (USCDI) Reason or indication for ordering or not ordering the medication
* reasonReference: (USCDI+ Quality) (USCDI) US Quality Core Condition or Observation that supports the prescription
* dosageInstruction: (USCDI+ Quality) (USCDI) How medication should be taken
* dosageInstruction.text: (USCDI+ Quality) (USCDI) Free text dosage instructions e.g. SIG
* dosageInstruction.timing: (USCDI+ Quality) (USCDI) When medication should be administered
* dosageInstruction.timing.repeat: (USCDI+ Quality) When the event is to occur
* dosageInstruction.timing.repeat.bounds[x]: (USCDI+ Quality) Length/Range of lengths, or (Start and/or end) limits
* dosageInstruction.timing.repeat.frequency: (USCDI+ Quality) Event occurs frequency times per period
* dosageInstruction.timing.repeat.frequencyMax: (USCDI+ Quality) Event occurs frequencyMax times per period
* dosageInstruction.timing.repeat.period: (USCDI+ Quality) Event occurs frequency times per period
* dosageInstruction.timing.repeat.periodMax: (USCDI+ Quality) Upper limit of period (3-4 hours)
* dosageInstruction.timing.repeat.periodUnit: (USCDI+ Quality) s | min | h | d | wk | mo | a - unit of time (UCUM)
* dosageInstruction.asNeeded[x]: (USCDI+ Quality) Take "as needed" (for x)
* dosageInstruction.route: (USCDI+ Quality) How drug should enter body
* dosageInstruction.doseAndRate: (USCDI+ Quality) (USCDI) Amount of medication administered
* dosageInstruction.doseAndRate.dose[x]: (USCDI+ Quality) (USCDI) Amount of medication per dose
* dispenseRequest: (USCDI+ Quality) (USCDI) Medication supply authorization
* dispenseRequest.validityPeriod: (USCDI+ Quality) Time period supply is authorized for
* dispenseRequest.numberOfRepeatsAllowed: (USCDI+ Quality) (USCDI) Number of refills authorized
* dispenseRequest.quantity: (USCDI+ Quality) (USCDI) Amount of medication to supply per dispense
* dispenseRequest.expectedSupplyDuration: (USCDI+ Quality) Number of days supply per dispense

Because this profile is derived from US Core, systems are also expected to support Must Support requirements and (USCDI) tagged elements inherited from US Core. The [Formal Views](#profile) section also provides the formal summary, definitions, terminology requirements, and mandatory element requirements.

### Profile Specific Implementation Guidance

To represent that a medication request was intentionally not requested for a medical, patient, or system reason, use the [US Quality Core Medication Not Requested](StructureDefinition-us-quality-core-medicationnotrequested.md) profile.

Additional informational guidance for authoring CQL using this profile is provided in the [CQL Authoring Usage (Informational)](#cql-authoring-usage-informational) section of this page.

**Usages:**

* Refer to this Profile: [US Quality Core Claim](StructureDefinition-us-quality-core-claim.md), [US Quality Core DiagnosticReport Profile for Laboratory Results Reporting](StructureDefinition-us-quality-core-diagnosticreport-lab.md), [US Quality Core MedicationAdministration](StructureDefinition-us-quality-core-medicationadministration.md), [US Quality Core MedicationAdministration Not Done](StructureDefinition-us-quality-core-medicationadministrationnotdone.md)... Show 2 more, [US Quality Core MedicationDispense](StructureDefinition-us-quality-core-medicationdispense.md) and [US Quality Core MedicationDispense Declined](StructureDefinition-us-quality-core-medicationdispensedeclined.md)
* Examples for this Profile: [MedicationRequest/cmd-example](MedicationRequest-cmd-example.md), [MedicationRequest/example](MedicationRequest-example.md), [MedicationRequest/patient-reported-example](MedicationRequest-patient-reported-example.md), [MedicationRequest/patient-requester-example](MedicationRequest-patient-requester-example.md) and [MedicationRequest/practitioner-ordered-example](MedicationRequest-practitioner-ordered-example.md)

### Notes:

#### CQL Authoring Usage (Informational)

To create an expression specifically requesting information that a MedicationRequest intentionally did not occur for a medical, patient or system reason, use the profile [USQualityCore-Medicationnotrequested](StructureDefinition-us-quality-core-medicationnotrequested.md).

The following example illustrates the use of the MedicationRequest profile:

```
define "Antithrombotic Therapy at Discharge":
  ["MedicationRequest": medication in "Antithrombotic Therapy"] Antithrombotic
    where (Antithrombotic.isCommunity() or Antithrombotic.isDischarge())
      and Antithrombotic.status in { 'active', 'completed' }
      and Antithrombotic.intent = 'order'
```
